Maybe It Is Not Just What You Eat, But How Much

We have become very good at asking what we should eat. What is the healthiest breakfast? Which oil should we use? Is rice better than roti? Should we have more protein? What should we eat for good digestion? There is always another food to add, remove, replace or worry about. But there is one much simpler question that often gets lost: how much are you actually eating? Ayurveda has been asking this question for a very long time. In the Matrashiteeya chapter of the Charaka Samhita, the discussion begins with something remarkably straightforward: matrashī syāt, essentially, one should eat in the right quantity. And then comes the important part that quantity is not exactly the same for everyone. It depends on the strength of one’s digestion. That immediately makes the conversation about food a little more interesting. Because we often speak about food as though the food itself is the whole story. We label something “light” or “heavy” and assume that its effect will be the same every time we eat it. But even foods considered naturally light or heavy still depend on quantity. Something that is generally easy to digest can become difficult when eaten in excess, while a heavier food may be manageable in an appropriate amount depending on the person’s digestive capacity. In other words, there is no point in asking only, “Is this food healthy?” without also asking, “Is this the right amount for me, at this time?” Eat according to the proper measure; the proper measure of food depends on the strength of digestion. It sounds almost obvious when you hear it, but think about how rarely we actually apply this idea. We eat because it is lunchtime even when we are not hungry. We continue eating because the food tastes good even after we are full. We finish everything on the plate because that is what we were taught to do. We order more because we are out with friends. Sometimes we eat very little all day and then compensate with a huge dinner because we are exhausted and starving. The food may not necessarily be the problem. Sometimes it is simply the relationship we have with quantity. The chapter makes another interesting distinction between foods that are naturally lighter and those that are naturally heavier. It mentions foods such as rice, green gram and certain meats among the lighter foods, while describing things such as preparations made from flour, sesame, black gram, milk and certain meats like fish as heavier. But even here, food is not reduced to a simple good-food versus bad-food list. It repeatedly brings the discussion back to quantity and digestive strength. This is important because the idea is not to become afraid of foods that are described as heavy. It is to understand that the same food can behave differently depending on how much of it you eat, how strong your digestion is and what else is happening in your body. You do not have to create a permanent list of foods you are “allowed” to eat and foods you are not. You can instead become more attentive to what happens after you eat. Do you feel comfortable? Does the meal digest without leaving you excessively heavy or sluggish? Are you hungry again at an appropriate time? Do you feel energised or do you feel like you need to lie down immediately? These observations are not meant to turn eating into another thing to obsess over. They are simply a way of becoming familiar with your own body. The appropriate quantity of food often supports one’s strength, complexion, comfort and longevity. That is quite different from the way we often talk about food today, where every meal can start to feel like a calculation of calories, protein, carbohydrates, fats and restrictions. Ayurveda’s concern here is much more functional: what does this food, in this amount, do to the person eating it? And it does not just stop with food. Health is maintained through small acts of care repeated regularly. Take something as ordinary as brushing the teeth. Your body is something you maintain, not something you only attend to when something goes wrong. We have a strange relationship with self-care today. We can spend hundreds of rupees on a product marketed as a “self-care essential” and still forget the basics. We can have a complicated skincare routine but sleep four hours. We can buy supplements while eating at completely irregular times. We can spend an hour researching the perfect shampoo and then ignore the fact that we are exhausted all week. Sometimes care becomes another form of consumption instead of something we actually practise. The Matrashiteeya chapter offers a much quieter idea of care. Eat in the right quantity. Keep yourself clean. Take care of the senses. Pay attention to the body. Maintain routines. Do things regularly rather than waiting until a problem becomes severe. There is a sense of maintenance rather than constant correction. And perhaps that is the part of this chapter that feels most relevant now. Eating when we are actually hungry. Stopping before we have eaten far beyond what we need. Paying attention to how a meal makes us feel instead of blindly following a food trend. Keeping our bodies clean. Taking a few minutes to care for our skin, hair, feet and senses. Giving the body enough rest. Building routines that are sustainable rather than impressive for a week. There is also something important in the way the chapter describes the body: almost as something that deserves regular attention and respect. Maybe that is what we miss when we reduce healthy living to individual foods and isolated habits. Because sometimes the most useful change is not finding a better food. It is learning when enough is enough. Health does not always come from… Continue reading Maybe It Is Not Just What You Eat, But How Much

Agnimandya: What Ayurveda Says About Weak Digestion

Have you ever noticed how two people can eat the exact same meal, and one feels perfectly fine while the other feels bloated, sluggish, or gassy an hour later? We usually attribute this to our different bodies but Ayurveda has a much more specific explanation for this, and once you understand it, a lot of your own digestive patterns start making sense. It’s called Agnimandya, and the word itself tells you exactly what it means. Agni is digestive fire, Mandya means a lowered or weakened state. Put together, Agnimandya literally translates to lowered digestive capacity. But before we get into what goes wrong, it’s worth understanding what Agni actually is, because I think this is where most people get it slightly wrong. Agni isn’t just “stomach acid” or metabolism. In Ayurveda, it’s considered one of the Panchamahabhuta, and its function mirrors that of Agni Mahabhuta in the universe at large, it’s the factor responsible for any transformation in matter. It’s the same force behind a mango ripening on a tree, as it is behind the food in your stomach being broken down into something your body can actually use. Specifically, the Agni that governs digestion is called Jatharagni, because it resides in the Jathara, the stomach. Whenever the term Agni comes up in this context, it’s really Jatharagni being referred to, not Dhatvagni, which operates at the level of individual tissues. And here’s the part most people fail to understand. Jatharagni’s real job isn’t just to “digest food.” It’s to convert the properties of food into the properties of your tissues. Wheat, for instance, carries a heavy, stable quality, what Ayurveda calls Guru and Sthira. Once Jatharagni processes it properly, those same qualities get transferred into your Dhatus, your tissues, in a usable, assimilable form. When this transformation happens cleanly, your tissues stay balanced. When it doesn’t, that imbalance shows up directly in your Dhatus, and eventually, as disease. This is really the whole premise behind why Agni is treated with so much seriousness in Ayurveda. It’s not just about comfort after a meal, it’s about whether your body is actually building itself correctly from what you feed it. Now, Ayurveda doesn’t describe Agni as one fixed, uniform thing. It actually breaks it down into four distinct states, based on how consistently and effectively it digests, and this classification alone tells you a lot about how this system really is. The first is Sama Agni, balanced digestive capacity. This is the ideal state, where food taken in the right quantity, what’s called Sama Matra, enough to satisfy hunger, not more and not less, gets digested smoothly, without discomfort, without excess, without deficiency. Ashtanga Sangraha even gives this a rough timeframe, food digesting within about four Yamas, roughly twelve hours. Sama Agni stays balanced as long as your conduct around food stays proper, and it’s our own poor habits that typically disturb it. This single idea alone reframes a lot of digestive complaints, because it suggests that for most people, balanced digestion isn’t a fixed trait you either have or don’t, it’s a state that holds as long as you don’t actively work against it. The second is Manda Agni, low digestive capacity, dominated by Kapha. This is the state where even a small meal feels heavy and takes far longer than it should to digest. What’s interesting is how intolerant this type is. Manda Agni can’t handle any deviation in eating habits, even minor missteps show up quickly as Aadhmana, bloating, Aasya Shosha, dryness in the mouth, Aatopa, abdominal distension, and Aantra Koojana, that gurgling sound in the intestines many of us have felt after a heavy meal we clearly shouldn’t have eaten. If you’ve ever felt like your body “punishes” you disproportionately for one slightly indulgent meal, there’s a decent chance Manda Agni is part of that story. Then there’s Teekshna Agni, sharp or excessive digestive capacity, dominated by Pitta. This is almost the opposite problem. Food gets digested fast, sometimes too fast, even when eaten in excess. It sounds like an advantage until you realize what happens when this type of Agni isn’t fed enough, it starts consuming the body’s own tissues instead, leading to Dhatu depletion over time. Taken to an extreme, this becomes a condition called Bhasmaka, a state of such intense digestive capacity that a person feels perpetually hungry, no matter how much they eat, almost as if the fire is burning through fuel faster than it can be supplied. What I find notable here is that Teekshna Agni can tolerate improper conduct around food far better than Manda Agni can, it just has a different kind of cost attached to that tolerance. And finally, Vishama Agni, irregular digestive capacity, dominated by Vata. This is the most unpredictable of the four. Some days digestion is fine, other days the exact same meal sits like a stone. Charaka specifically describes this as the direct opposite of Sama Agni, unstable, inconsistent, and a major contributor to Dhatu imbalance over time. Interestingly, Vishama Agni can behave in two completely opposite ways depending on the amount eaten, food consumed beyond actual hunger may digest surprisingly fast, while food eaten in a reasonable, hunger-appropriate amount might digest very slowly instead. This unpredictability is exactly what makes it so hard for people with this pattern to pin down what’s actually “wrong” with their digestion, because the pattern itself keeps shifting. Out of all four, only Sama Agni is considered the healthy baseline, responsible for Dhatu Saamya, true balance across all seven tissues. The other three are classified as Vikrita, disturbed states, and this is really where Agnimandya comes in specifically. Technically, Agnimandya refers to Manda and Vishama Agni, the Kapha-dominant and Vata-dominant disturbances, both of which share that core feature of reduced or inconsistent digestive strength, as opposed to Teekshna Agni, which is excessive rather than diminished.… Continue reading Agnimandya: What Ayurveda Says About Weak Digestion

Ama: When Digestion Is Incomplete

After you have had your meal, there might be times when you feel heavy. It is not exactly tiredness, but you do not feel nourished either. Your head feels foggy, there is a discomfort you cannot quite ignore, and yet it is not severe enough to feel like something is seriously wrong. There may also be a feeling that you have not experienced complete satisfaction from the meal. It is almost as though something inside you is saying that the process is not finished, that the job has not been completed. Today, we are going to talk about one of the widely spoken-about concepts in Ayurveda: Ama. When the accumulation of Ama is greater, it can give rise to a condition described as Amadosha. To understand Ama, we have to go back to something we have spoken about before: Agni, our digestive fire. What Is Ama? Ashtanga Hridayam describes this state directly. When the digestive strength is low, the very first tissue formed from food, which remains undigested, becomes vitiated and gets lodged in the stomach as unprocessed matter. This is described as Ama. When Agni is working the way it should, the food we consume gets properly digested, absorbed, and converted into Rasa Dhatu, the first and most essential tissue our body produces after digestion. But when Agni is weak, this conversion does not happen cleanly. Your food is not entirely digested, but it is not entirely rejected either. Some of it remains half-processed, turning into something called Ama. Ama is not exactly food. It is not waste either. It is something caught in between the two, the result of incomplete digestion and improper transformation. What Causes Ama? One of the causes is eating more than what your hunger can accommodate. Ayurveda describes this as atimātrā āhāra, or consuming food in excessive quantity. When food is consumed in a quantity greater than what the digestive capacity can handle, it places a burden on Agni. This can lead to the aggravation of all three doshas and interfere with proper digestion. But it is not exactly about quantity alone. The nature of the food also matters. Food that is heavy, dry, or cold can contribute to the formation of ama, even when it is eaten in a reasonable amount. And it is not just about food. Your lifestyle, mental strain, and the mental state you carry throughout the day can also contribute. When your digestive capacity is compromised, even food that you consider light or harmless may not be processed properly. When Agni is weak, food does not necessarily provide the nourishment your body requires. Instead, according to the Ayurvedic understanding of ama, incompletely processed material can behave like a slow-acting poison within the body. What Happens When Ama Interacts With the Doshas? As this undigested or improperly processed material interacts with the doshas, its effects can vary depending on how the body responds. It may become trapped and cause a condition described in Ayurveda as Alasaka. Or it may be expelled violently from the body, which is described as Vishoochika. Either way, the body is signalling that something has gone wrong in the process of digestion and assimilation. The manifestation can also differ depending on which dosha is involved. When Pitta is involved, you may see signs such as a burning sensation, excessive thirst, and disturbances in the mouth, reflecting more heat-related expressions. When Kapha is involved, it can manifest differently, with congestion-type conditions, urinary disorders, and other Kapha-dominant patterns. This is why Ayurveda does not look at digestion as simply a matter of what you eat. It considers the strength of Agni, the nature and quantity of food, the timing of meals, lifestyle, mental state, and the condition of the doshas together. Ama, in this sense, is not simply about having eaten something unhealthy. It is about what happens when the body is unable to properly process what it has received. What Are the General Properties of Ama? Ayurveda describes Ama as having certain characteristic properties. It is guru, meaning heavy and difficult to digest. It is drava, meaning it has a liquid nature. It is aneka-varṇa, meaning it can present in different colours. And it is picchila, meaning slimy or sticky in nature. The symptoms associated with ama are often the kind most of us have experienced at some point. There may be a sense of blockage or obstruction, general exhaustion, heaviness in the head, dizziness, stiffness in the back and hips, unusual thirst, and that general feeling that whatever you eat is simply not sitting right. Individually, none of these symptoms may seem particularly alarming. But when several of them appear together, they can indicate that something is not functioning properly within the digestive system. The answer is not always to simply eat less, eliminate one particular food, or ignore the discomfort and wait for it to disappear. Ayurveda asks us to look deeper at Agni. How strong is your digestion? Are you eating according to your hunger? Are you eating at regular times? Is the food appropriate for your digestive capacity? Is your lifestyle supporting digestion, or constantly working against it? Because digestion is not merely about what happens to food after you swallow it. It is about how well the body is able to transform what it receives into nourishment. If ideas like Ama and Agni interest you, our courses on Charaka Samhita and Ashtanga Hridayam go much deeper into understanding digestion, imbalance, and the way our body responds to what we eat, how we live, and how we care for ourselves.

Amla: Everything I Tell My Patients About How To Have It

Someone asked me the other day if I like matcha. No. I have something better. And we Indians have had it forever. It is amla. Our humble Indian gooseberry. Now everybody will tell you amla is good. Amla is good, amla is good. But nobody is telling you how much to have, when to have it, in what form, and what to do if you cannot get it fresh. So that is what I am going to tell you here. Exactly what I tell my patients. First, what amla actually is in Ayurveda In Charaka Samhita, amalaki is placed in the vayasthapana mahakashaya. That is the group of ten drugs classified as age sustaining. Age sustaining. Not anti-ageing. There is a difference, and Ayurveda made that difference two thousand years back. Now here is what most people get wrong. Amla tastes sour. So everybody assumes it is heating. It is not. Amalaki is sheeta virya. Cold in potency. And madhura vipaka. Sweet after digestion. This is what Bhavaprakasha Nighantu tells us. So, both of these are going against what your tongue is telling you. Your tongue says sour, your mind says heating. But that is not what is happening inside. And this is exactly why amla calms pitta, when almost every other sour thing will increase it. And that sweetness you feel in your mouth after eating amla, especially when you drink water on top of it? That is not vipaka. Vipaka is happening hours later, in your tissues. People mix up these two all the time. The best form is the fruit. Always. One amla a day itself is great. That is the whole thing. If fresh amla is naturally available to you, please have it like that. Do not overthink it. Do not go looking for a supplement. The fruit is the best form and nothing beats it. And amla comes in the cold season. That is not by accident. Nature is giving it to you exactly when you need it, so that is when you should be having it. So, when it is in season, eat it. Every day. Your body knows what to do with it. If you cannot get fresh amla, then powder Now most of you reading this are not in India. I know. Half of my patients are in places where amla is only available as a powder in a packet. That is okay. Powder works. But please listen to me about the quality. Get organic. Get good quality. And I mean really check. Because we have no idea where these people are drying it. We have no idea where they are powdering it. We have no idea what it went through before it came into that nice looking jar. So, if you are not sure about the source, better to avoid it. Really. Do not have it at all rather than having something you cannot trace. But if you are sure, if you know where it was dried and how it was powdered and how authentic it is, then go ahead. Find the best quality you can. I know I am dragging on too much about quality. I know. But this is more important than the dose, more important than the timing, more important than anything else in this whole article. A bad powder is not a weaker amla. It is a completely different thing. How much: one teaspoon of powder mixed into your food. That is the easiest way and the safest way, and this is what I tell most of my patients. Amla juice, please read this part carefully You can have amla as a juice. But as a shot. Not as a glass. Never drink a full glass of amla juice. Please. Do not take ten, fifteen amlas and make a big juice out of it and sit and drink it. Do not do it. Instead do this: Crush two or three amlas Add a little water Add pepper, turmeric, dry ginger A little Himalayan pink salt If you do not like the salt, add mishri or rock sugar instead And have it like a shot. Not more than 25 ml. That is it. Every day in the morning. That is enough. Timing and Anupana Morning is good. Have your shot in the morning. If you have a very strong acidic stomach, then have it after food. It works just as well and it is gentler on you. Anupana for amla is always water. Keep it simple. And there is one more way which I love, and most people have not even heard of it. Take amla powder, mix it with a little ghee, and have it with the first morsels of rice at lunch time. Beautiful way to take it. You can do the same at dinner also. Now, amla does not cause acidity I have to correct this one, because I am hearing it constantly. Amla does not cause acidity. It cannot. Once it goes into your stomach it cools down and it turns into sweet taste. It is not going to heat you and it is not going to burn you. It actually reduces acidity. Now if your stomach lining is already raw and inflamed, a concentrated shot on an empty stomach can still feel like too much for you. But that is the concentration doing it, not the amla. And that is exactly why I said have it after food. And see the irony here. People think curd is cooling. It is not. Classically dadhi is ushna virya with amla vipaka, and it is abhishyandi, it blocks your channels. It is doing almost the opposite of… Continue reading Amla: Everything I Tell My Patients About How To Have It

Agni: Why the Same Food Affects Everyone Differently

Ayurveda says that your body’s ability to digest and transform food into nutrients differs from person to person. Modern nutrition has also come to a similar understanding: everybody’s body is different. But let us look at this a little deeper. Imagine two people having the same meal, in the same quantity, at the same time. But one might feel energetic and satisfied after eating, while the other might feel bloated, heavy, or dizzy. So, how is that possible? This is because of what Ayurveda describes as Agni, or digestive fire. The strength and quality of your Agni determine how well your body digests food, absorbs nutrients, eliminates waste, and produces energy. In other words, it is not just what you eat that matters; how your body processes the food you eat matters just as much. And Agni is more than digestion. In Ayurveda, Agni is more than just digestive enzymes or stomach acid. It represents the entire process of transformation happening inside your body, from breaking down food to supplying energy, nourishing the tissues, and supporting immunity. Ayurveda describes 13 different types of Agni, with the most important one being Jatharagni, the main digestive fire located in our digestive tract. When we talk about the overall state of digestion, Ayurveda mainly focuses on four different types of Agni. Each one reflects a different pattern of digestion and relationship with food. Let’s look at them in detail. Sama Agni: Balanced Digestion Sama Agni is considered the ideal state of digestion, where your Agni is balanced, your food gets processed efficiently, and you get hungry at regular intervals of time. Your appetite is steady. Your energy remains stable throughout the day, and you feel satisfied after eating your meals. So, someone with Sama Agni has a healthy ability to digest and process food efficiently. That does not mean they can eat unhealthy food all the time. It simply means that their digestion is functioning the way it should. The goal is not to have a digestion that allows you to eat anything without consequences. The goal is to have an Agni that is balanced enough to digest, transform, nourish, and eliminate efficiently. Vishama Agni: Irregular Digestion The second type is Vishama Agni. Vishama means irregular, and it describes digestion that is irregular or unpredictable. Some days you may have a good appetite, while on other days, you may not feel like eating at all. Some days you may feel bloated after eating or sluggish after your meals. You may also experience irregular bowel movements. This pattern is mostly associated with aggravated Vata, which is linked with movement and irregularity within the body. When Vata becomes irregular, digestion can also become irregular. People with Vishama Agni may find that their hunger, digestion, bowel movements, and even their response to food can change from day to day. So, how do you overcome this? It can be as simple as maintaining consistent meal times, eating warm, home-cooked meals, and following a steady daily routine, or Dinacharya. Because Vata is a quality that drives irregularity, it can be calmed by consistency. Sometimes, the answer is not another supplement or another complicated diet. It is simply giving your body a predictable rhythm. Tikshna Agni: Sharp or Intense Digestion The third is Tikshna Agni, which means sharp or intense digestion. This is when your digestion becomes strong and fast, and sometimes, too strong. People with Tikshna Agni may experience intense or frequent hunger. They might get hungry very quickly, digest food very quickly, and may be able to tolerate spicy or heavy meals. At first, this might sound like something good. But Tikshna Agni is often linked with aggravated Pitta, which is associated with heat and intensity. If it is not managed well, you may experience acidity, heartburn, excessive heat, or inflammatory-type conditions. The goal here is not to suppress digestion, but to balance its intensity. It is suggested to take moderately cooling foods in nature and avoid excessive spice or very hot, acidic foods. Instead of skipping meals, maintain a regular Dinacharya, eat at consistent times, and stay adequately hydrated. When Agni is too sharp, giving it more stimulation is not necessarily the answer. Sometimes, it needs moderation. Mandagni: Slow or Weak Digestion The fourth type is Mandagni. Manda means slow or weak. Mandagni is characterised by a low appetite and slow digestion. After eating your meals, you may feel sluggish, heavy, or lethargic. You might also experience mental fog after eating. Over time, this heaviness may also affect how you feel mentally as well. Mandagni is associated with aggravated Kapha. This is also the condition most directly linked with Ama accumulation in Ayurveda. Ama is often described as a form of accumulation that can occur when food and metabolic processes are not properly processed. Because the digestive fire is slow, food is not processed efficiently. This can lead to partially digested material accumulating in the system, which Ayurveda describes in terms of Ama. This is why Ayurveda does not look at digestion simply as whether you are eating the “right” food. The same food can affect two people differently because their Agni may be different. One person may eat a meal and feel energetic, satisfied, and comfortable. Another person may eat the exact same meal and feel heavy, bloated, sluggish, or uncomfortable. The food is the same. But the person processing the food is not. And this is one of the reasons Ayurveda places so much importance on Agni. It is not simply about what enters the body. It is also about the body’s ability to transform what enters it. Understanding your Agni gives you a different way… Continue reading Agni: Why the Same Food Affects Everyone Differently

Fasting in Ayurveda: Beyond Intermittent Fasting and Weight Loss

Fasting has become one of the biggest health trends in recent years. You have probably heard of intermittent fasting, time-restricted eating, or 16:8 fasting. Researchers have spent years studying these patterns, and studies suggest that giving your body regular breaks from food can improve metabolism and support overall health. But before fasting even became popular, Ayurveda had already recognized its value. More than 2,000 years ago, Ayurveda described this approach as Langhana. Rather than viewing fasting simply as a way to lose weight, Ayurveda viewed it as a method to help the digestive system recover and function better. In the Charaka Samhita, one of Ayurveda’s oldest and most fundamental texts, there are two approaches to treatment. One is Brimhana, which means nourishing and strengthening the body. The other is Langhana, which is to make the body lighter. Langhana includes fasting, eating less, or taking lighter meals over a period of time to give your digestive system a chance to improve. Both approaches are used for different situations. Someone who is weak and recovering from illness may need Brimhana to rebuild their strength, while someone who feels sluggish, heavy, and has poor digestion will benefit from Langhana. There’s one important distinction we need to understand here. Langhana and fasting are not the same thing. In Ayurveda, Langhana is the broader therapeutic principle of lightening the body and reducing the burden on digestion and metabolism. It is one of the two fundamental approaches to Chikitsa. Fasting, or Upavasa, is simply one of the methods used to achieve Langhana. In the Charaka Samhita, Langhana is described through Dashavidha Langhana, or ten methods of producing the lightening effect in the body. Upavasa (fasting) is one of them. Others include Atapa Sevana, therapeutic exposure to sunlight; Pipasa, controlled restriction of water intake in carefully selected situations; Vyayama, exercise; and Deepana-Pachana, therapies that stimulate digestion and help clear accumulated Ama. The approach always depends on the person’s Agni, strength, disease, and overall constitution. This is an important difference in how fasting should be discussed today. Ayurveda never treated fasting as something everyone should be doing. It was only recommended when the body needed it. Digestion Comes First In Ayurveda, digestion is the centre of health. When Agni works well, food is broken down properly, nutrients are absorbed, and waste is eliminated. That is when the body stays healthy. But if digestion is weak, it may result in the formation of Ama, leaving you with signs like bloating, sluggishness, and heaviness. The underlying problem is very simple. A digestive system that is constantly overloaded with food might not work efficiently. Sometimes, instead of adding more food, you can benefit by consuming less or having less to process. That is why the approach of Langhana exists. It gives the digestive system time to soothe, recover, and catch up, because your body also needs rest. Where Modern Science Meets Ayurveda While modern science and Ayurveda explain the body differently, they have arrived at similar conclusions about fasting. In 2016, the Nobel Prize in Physiology or Medicine was awarded to Yoshinori Ohsumi for his work on the mechanisms of autophagy. Autophagy is the process where cells internally break down and recycle damaged components. His subsequent research showed that fasting can activate autophagy, essentially giving cells the chance to clear out accumulated waste that has been building up from continuous eating. This is the cell’s self-cleaning process. At a conceptual level, this may appear similar to the Ayurvedic idea of clearing Ama, although the two come from very different frameworks. There was also research led by neuroscientist Mark Mattson, published in the New England Journal of Medicine, which described what is now called the metabolic switch. You might have heard of this phrase. It is the shift that occurs roughly 12 hours or more into a fast, when your body moves from burning readily available glucose to burning stored fat and producing ketones. This switch has been shown to improve insulin sensitivity, reduce inflammatory markers, and improve stress resistance at the cellular level. Separately, there was also research led by biologist Satchin Panda, who focused on time-restricted eating. His studies commonly examined eating within an 8 to 12 hour window rather than eating across 14 to 16 hours. Trials in this area have linked consistent eating windows with improvements in blood sugar regulation, blood pressure, and body composition. He also proposed that the digestive system and metabolic organs like the liver, pancreas, and gut all operate on their own daily rhythms. Giving them a predictable time to rest each day allows them to function more efficiently rather than processing food unpredictably around the clock. This is interesting when viewed alongside the Ayurvedic concept of Dinacharya, which has long emphasized regularity and consistent meal timings. The emphasis Ayurveda has always placed on regular timing and regular intervals of food, combined with Langhana. Ayurveda has never separated these pieces of advice. They were always treated as part of the same principle for supporting the digestive system. The Real Takeaway The point I’m trying to make is not that Ayurveda has been proven right by science. No. The more accurate and useful point is that two very different systems, despite being separated by thousands of years and built on completely different ways of understanding the body, have independently arrived at the same core insight. Our digestive system needs structured, deliberate breaks to recover and function well. And this is not the same thing as simply eating less overall. These few simple principles behind Langhana are worth holding on to. Consistent meal timings matter just as much as what your meal contains. Leaving real gaps between meals is important because it gives the digestive system a chance to do its job. Not everyone needs the same… Continue reading Fasting in Ayurveda: Beyond Intermittent Fasting and Weight Loss

Why Two Healthy Foods Don’t Always Belong Together?

Sometimes I believe we look at food in a very simple way, in the sense that we don’t question it. We look at two foods that are healthy, like for example, a fruit is healthy, milk is healthy, and yogurt is healthy. Then we think, okay, if we mix these two healthy foods, the result will also be healthy. But that is not always true. More than 2,000 years ago, the Charaka Samhita introduced a concept called Viruddha Ahara, which means incompatible food combinations. The idea behind this is that a food is not only judged by what it is, but also by how it is eaten, how it is prepared, what it is eaten with, and who is eating it. Taking all these factors into account is important because two foods can be good on their own, but when combined, may not result in a good combination when eaten together. This is a very different way of thinking about food and nutrition. Normally, the questions that pop into our mind when we think about food are: Is it high in protein? Does it contain any vitamins? Is it low in sugar? Or is it natural or processed? But we should ask different questions. What is this food being combined with? How is it being prepared? Is the right amount being consumed? Is it the right season to eat it? Can my digestion handle it? Now, instead of looking at foods one by one, Ayurveda looks at the relationship between foods. According to the Charaka Samhita, there’s not just one kind of food incompatibility. There are 18 different ways in which food can become unsuitable when combined. Keep in mind that food is affected by where, when, how, how much, and with what it is eaten. Let us look into some of the most important types of Viruddha Ahara. First is Desha Viruddha, which means some foods are better suited to certain climates than others. A food that might work well in a cold region might not be the best choice to be eaten in a hot or humid place. Kala Viruddha refers to, as the name signifies, the season and time of the day. Eating heavy and oily foods during summer, or eating meals that are difficult to digest at night, might not suit the body and is not suggested. Agni Viruddha means digestive strength. Not everyone can digest food in the same way. A meal that might feel light for one person may feel heavy and uncomfortable for someone with weaker digestion. Matra Viruddha means quantity. Even healthy food becomes unhealthy when taken in excess amount. It is important to keep in mind that the right amount of food is as important as the right food. Then there is Samskara Viruddha. The way food is cooked, stored, and processed also changes how it affects the body. The same ingredients may have different effects depending on how they are prepared. Virya Viruddha refers to the inherent qualities of food. Some foods have warming qualities, while others have cooling qualities. Combining foods with opposite properties might not always be a good choice. Samyoga Viruddha refers to foods that do not work well together, even when each of them is healthy on its own. One of the best-known examples of Samyoga Viruddha is milk with sour fruits. According to Ayurveda, milk has a cooling nature, while sour fruits are heating and acidic. The classical texts explain that this combination can disturb digestion, increase heaviness, and create discomfort. Many people may have experienced this without realizing, like after consuming certain fruit-and-milk combinations, such as a smoothie or milkshake, they may feel bloated, heavy, or simply feel that the meal “didn’t sit well.” Now, Viruddha Ahara is not just a small idea presented in Ayurveda. It is an important concept because it is considered one of the major causes of disease. In the Charaka Samhita, incompatible food combinations are described as a major reason for several health problems, especially those related to the skin. They are also linked with inflammation, poor digestion, and, in some cases, even disturbances of the mind. Vagbhata has also described incompatible food combinations as being poison-like. This doesn’t mean they act like a poison after every single meal. It means that when these combinations are consumed repeatedly over months, they might gradually affect your health. The effects may show up as bloating, discomfort, inflammation, and other digestive issues. So, the next time you are trying to consume something healthy, ask yourself if that combination of foods or ingredients is actually healthy for your body.

Share it with someone who might find it interesting, and let us know in the comments if you’ve ever noticed certain food combinations affecting your digestion or how you feel. As next, we’ll explore some of the most well-known incompatible food combinations described in Ayurveda.

Protein vs Digestion: What Ayurveda Teaches About Building Muscle

If you are hitting the gym today, or even just opening a health app on your phone, there’s probably one thing you’ll notice immediately: protein intake. Thirty grams for breakfast, twenty-five grams for lunch and even a protein shake after your workout to hit your daily target. Protein has become so ingrained in modern nutrition that we rarely stop to question it. But here’s something interesting. Ayurveda, one of the world’s oldest continuously practised systems of medicine, never counted protein at all. Why? Let’s understand protein in a simple way. Protein helps build muscle and supports strength. Many people assume that the more protein we eat, the stronger we become. But the amount of protein you eat isn’t necessarily the amount your body digests, absorbs, and uses. This single difference changes everything. The World Has Become Obsessed With Protein Protein is everywhere today. The global protein supplement industry is now worth over $30 billion, and millions of people are actively trying to increase their daily protein intake. Protein powders, protein cereals, protein bars, protein water, almost every food category now has a protein version. The question is not whether we need protein. It has become how can we eat even more of it? Research suggests that most Americans already meet or exceed the Recommended Dietary Allowance (RDA) for protein. Consuming protein far beyond these requirements doesn’t automatically lead to additional muscle gain or health benefits, particularly for sedentary individuals. At the same time, many people are actually falling short on nutrients like fiber, calcium, potassium, and several B vitamins. India has a similar story. You may have heard the claim that 73% of Indians are protein deficient. But that number comes from a relatively small market survey rather than a nationwide nutritional assessment. Protein intake varies considerably across India. While many people meet their basic physiological requirements, others, particularly older adults, women, and lower-income populations, may still consume inadequate amounts. The bigger question isn’t simply how much protein we’re eating, it is whether our body is actually able to absorb and use it properly. Ayurveda Never Looked at Food This Way One of the basic principles of Ayurveda is that food is understood by how it behaves inside your body, not by how many grams of protein, carbohydrates, or fat it contains. In other words, Ayurveda is less interested in the food itself and more interested in what that food does to your body. Every food is understood through its taste, qualities, energy, and what happens after digestion. The Chandogya Upanishad describes what happens when food is eaten, it explains that the heaviest part becomes waste, the finer part nourishes the body, while the subtlest portion supports the mind. The remaining part contributes to building the body’s tissues, including muscle. So Ayurveda never denied that food builds muscle. It simply believed that something else comes first. You might have heard of the saying, you are what you eat. But I believe it extends to you are what you digest. Every meal you eat has the potential to nourish you but only if your body can properly absorb it. Food doesn’t become muscle the moment you swallow it. It first has to be digested, the nutrients must then be absorbed and gradually transformed into the body’s tissues. Ayurveda describes this as a sequential process of tissue nourishment that eventually supports blood, muscle, fat, bone, marrow, reproductive tissue, and finally Ojas, the body’s deepest reserve of vitality and resilience. For all of this to happen efficiently, your digestion has to be working well. Why Ayurveda Focuses on Agni This is why Ayurveda places so much importance on Agni, the digestive fire. When your Agni is strong, food is digested efficiently, nutrients are absorbed properly, and the body receives nourishment. But when Agni becomes weak, the body struggles to digest and process food effectively. Instead of being completely transformed into nourishment, part of the food remains partially digested. Ayurveda calls this Ama. Ama is described as incompletely processed metabolic waste. According to Ayurveda, its accumulation is considered the starting point for many diseases. This is why simply adding more food or more protein is not always the answer if your digestion is weak. Eating more protein does not automatically mean your body will build more muscle. The first step is improving digestion. Modern Science Is Beginning to Ask Similar Questions Interestingly, modern nutrition is beginning to explore many of these same ideas. One 2024 study published in Nature Metabolism reported that consuming more than approximately 25 grams of protein in a meal reduced markers associated with autophagy, the body’s natural process for clearing damaged cells. Researchers are increasingly recognising that digestion, gut health, and nutrient absorption are just as important as nutrient intake itself. High-protein diets can also unintentionally reduce fiber intake if they replace plant-based foods. This matters because dietary fiber feeds beneficial gut bacteria and plays an important role in long-term digestive and metabolic health. In some respects, modern nutrition is beginning to explore concepts that echo principles long emphasised in Ayurveda, particularly the importance of digestion, gut health, and nutrient utilisation. The body is not just a container for nutrients. It is a living system that must digest, absorb, and transform food before it can become nourishment. So Should You Stop Eating Protein? Absolutely not. Protein is an essential nutrient, it helps build muscle, repair tissues, produce enzymes, hormones, and support numerous physiological functions throughout the body. I am not asking you to stop eating protein. I am asking you to stop thinking that more protein automatically means better health. Instead of asking,… Continue reading Protein vs Digestion: What Ayurveda Teaches About Building Muscle

The World’s Healthiest Man Just Got an Autoimmune Disease. Here’s What Ayurveda Saw Coming.

By now, you’ve probably seen the headlines. Bryan Johnson, the man who spends $2 million a year trying not to die, who calls himself the healthiest person on Earth, whose entire movement is built around the slogan “Don’t Die,” has been diagnosed with a chronic autoimmune condition called autoimmune gastritis. I want to walk you through this properly. Not to mock him, there’s nothing funny about watching your own body turn against you. But because his story is, painfully, one of the clearest modern illustrations I’ve seen of something Ayurveda has been saying for three thousand years: disease does not begin on the day it is diagnosed. It begins long before, quietly, in the digestion. What Actually Happened Inside His Body Here’s what we know from his own account. For years, his medical team noticed his ferritin, the protein that stores iron in the body, was persistently low. They couldn’t explain it. He wasn’t anemic. He wasn’t bleeding. He simply wasn’t holding onto iron the way he should have been. Eventually, that unresolved clue led to further testing: a colonoscopy, an endoscopy, biopsies of the stomach lining. What they found was early-stage autoimmune gastritis. His own immune system had begun attacking the acid-producing cells of his stomach lining. Left unaddressed, this kind of damage is progressive. It can impair the body’s ability to absorb vitamin B12 and iron, and over time, it raises the risk of stomach cancer. He’s also spoken about the fact that this didn’t emerge on its own. He was diagnosed with hypothyroidism at 21. He describes a childhood of sugar, soda, and fast food, followed by a stretch in his 20s marked by heavy stress, weight gain, and a deep depression while he was building his business. What he now calls “thyrogastric syndrome,” his thyroid and his stomach’s autoimmunity feeding off each other, didn’t arrive out of nowhere. It had been building for decades. Why Low Ferritin Was the Clue, Not the Cause This is the part I want you to sit with, because it matters far beyond one man’s diagnosis. Low ferritin wasn’t the disease. It was the smoke, not the fire. It was the first visible signal of something that had already been happening for years, invisible to every panel, every scan, every biomarker his team was tracking. He had, by his own description, more data on his body than almost any human alive, and none of it caught this until the damage had already begun. This is precisely where modern diagnostics and Ayurveda part ways. Modern medicine is extraordinary at identifying disease once it has a name, once there is a lesion, an antibody, a measurable marker. But by the time something is measurable, it has usually already gone through years, sometimes decades, of a much quieter process. Ayurveda was built to look upstream of that, to ask not “what is wrong,” but “how long has something been going wrong.” The Ayurvedic View: Where This Condition Actually Begins In Ayurveda, a condition like this is never understood as a sudden immune malfunction. It is understood as a deeper disturbance, one where undigested metabolic waste (Ama), disturbed doshas, and a weakened Agni come together in the Amashaya, the stomach, and begin to block the body’s channels of circulation and elimination. This is the real story behind autoimmune gastritis, from an Ayurvedic lens. Agni, your digestive fire, is not just about breaking down food. It governs how well every tissue in your body is nourished, and how efficiently waste is cleared. When Agni weakens over years of poor digestive habits, food is no longer fully metabolized. What remains is Ama, a sticky, toxic residue that Ayurveda has described for millennia, long before the language of “inflammation” or “autoimmunity” existed. This Ama doesn’t stay put. It circulates. It aggravates the doshas. And eventually, it lodges in a specific site of weakness, in this case, the lining of the stomach itself, the Amashaya, where it blocks the subtle channels (srotas) responsible for healthy tissue function. Over time, this is what creates the conditions for the body to begin attacking its own tissue. So when Ayurveda looks at disease, it does not only ask what the diagnosis is. It asks: how long has your Agni been struggling before the diagnosis finally appeared? The Causes, And Why They Are Painfully Relevant Today What causes Agni to weaken to this point? Ayurveda is remarkably specific about this, and honestly, reading through these causes today feels less like ancient scripture and more like a description of how most of us are actually living. Ajirna and Adhyashana: eating before the previous meal has been digested. Layering meal on top of meal, snack on top of snack, without ever letting Agni complete its work. Viruddha, Guru, Sheeta, Ruksha, Ashuchi, and Vidahi Ahara: food that is incompatible in combination, heavy to digest, cold, dry, impure, or inflammatory in nature. This is your ice-cold smoothie after a heavy meal, your reheated leftovers eaten mindlessly, your ultra-processed food with no living Prana left in it. Vishamashana and Samashana: eating at the wrong time, in the wrong quantity, or mixing suitable and unsuitable foods together in the same meal, so that Agni is asked to process contradictory signals at once. Manasika factors while eating: eating while gripped by grief, anger, stress, or emotional exhaustion. Ayurveda has always understood that the mind digests the meal as much as the stomach does. Vagbhata, one of the great classical authorities of Ayurveda, was explicit about this. He describes food that is unsuitable to the individual, heavy, dry, cold, unclean, or inflammatory to the system as a direct cause of digestive breakdown. He also names the patterns around eating as equally dangerous: eating again before the previous meal is digested, eating at the wrong time, eating… Continue reading The World’s Healthiest Man Just Got an Autoimmune Disease.

The Future Doctor Will Not Just Treat Disease

For a long time, healthcare has always been about this one question: How do we treat disease? It learned to spot symptoms and diagnose problems. That is how it worked. But today, a new question has emerged because of the lifestyle changes people have experienced over the past 50 years due to technological advancement. That question is: How do we keep ourselves healthy and prevent disease from developing? The focus is no longer on waiting for a diagnosis or for disease to strike. It is about asking how we can keep a person well in the first place so they don’t get a disease. This big shift has changed the healthcare industry. And Ayurveda, from the start, has always been about preventive care rather than treating disease. This also changes how we look at the role of a doctor. A doctor is not only someone who steps in when something goes wrong. A doctor also helps a person understand what is happening inside the body long before disease develops. Looking Beyond Symptoms Symptoms are important. They tell us that something needs attention. Modern medicine has made remarkable progress in diagnosing and treating diseases. But Ayurveda looks at another part of the picture. It asks what may have disturbed the body’s natural balance before those symptoms appeared. Was it irregular eating? Poor sleep? Too much stress? A lack of movement? Or was it a combination of small daily habits that slowly added up over time? Understanding these patterns helps us understand the person, not just the disease. Disease does not appear overnight One of the most important ideas in Ayurveda is that disease rarely appears all at once. The body usually gives small signals before a larger problem develops. They are often easy to ignore because they do not stop us from carrying on with our day. It may begin with poor digestion after meals. It may be feeling tired even after a full night’s sleep. Some people notice changes in their appetite. On their own, these may not seem like major concerns. Most people learn to live with them. They become part of the daily routine. Health Is Built Every Day Most of our health is shaped by the choices we repeat every day. The time we wake up. The food we eat. How well we digest it. How much we rest. How we respond to stress. These may seem like small things, but together they influence how the body functions over time. What Prevention Is Not About Sometimes people think preventive care means never getting sick. That is not realistic. Anyone can fall ill despite taking good care of themselves. Prevention is about giving the body the best possible support so it can function well. It is about recognising small changes early and making simple corrections before they become bigger concerns. It is a practical way of caring for health. Why This Matters More Than Ever The reason this feels urgent right now is not a coincidence. Lifestyles have changed dramatically over the past few decades. Sleep schedules have become irregular. Food is more processed than it used to be. Screens keep people sitting still for most of the day. Stress has become a constant. These changes did not happen suddenly. They built up slowly, year after year, the same way disease often builds up slowly in the body. This is exactly why the question of prevention matters so much today. The conditions that create imbalance are far more common today than they once were, which means the need to understand those patterns is more important now too. The Future Doctor If this shift continues, and there is every sign that it will, the doctor of the future will look a little different. That doctor will still treat disease well. That part of the job does not go away. But that doctor will also sit with deeper questions regularly. Why did this imbalance begin? What daily pattern led here? What small change can prevent it from happening again? Ayurveda has trained doctors to think this way for a very long time. As modern medicine slowly moves toward prevention, it is really just walking a path Ayurveda walked long before it. This is not Ayurveda changing to catch up with medicine. It is medicine finding its way back to a question Ayurveda never stopped asking. If this got you thinking about your own health, your daily habits, or why your body responds the way it does, our Charaka Samhita and Ashtanga Hridayam courses are a great place to start. They take you back to the foundations of Ayurveda, helping you understand its principles directly from the classical texts and how they can be applied to everyday health.
