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 High Blood Pressure Is Increasing in People in Their 30s and 40s?

  High blood pressure is no longer considered a condition that appears only after the age of 60.   Today, more and more people in their 30s and 40s are being diagnosed with hypertension, especially those with a family history of diabetes, obesity, cholesterol imbalance, or cardiovascular disease.   Many people believe high blood pressure is simply caused by stress or excess salt intake. While these factors do play a role, the deeper issue is often metabolic dysfunction, particularly insulin resistance.   Let us understand this in a simple way.   The Connection Between Insulin Resistance and High Blood Pressure   Our body produces a hormone called aldosterone.   This hormone tells the kidneys to retain sodium (salt). When salt is retained in the body, water also stays back. Increased water retention raises blood volume, and when blood volume increases, blood pressure rises.   Now here is where insulin resistance becomes important.   People with insulin resistance often have higher insulin levels circulating in the body. Elevated insulin can stimulate the retention of sodium and water, making the body more prone to developing high blood pressure.   This is why people with: Belly fat Weight gain Fatty liver High cholesterol Prediabetes Sedentary lifestyles   often gradually develop hypertension as well.   Ayurveda sees this pattern as a Kapha-dominant metabolic disorder associated with weak Agni, Ama accumulation, sluggish circulation, and blocked channels.   The good news is that Ayurveda focuses not just on controlling blood pressure numbers but on improving the underlying metabolic imbalance itself.   Ayurvedic Principles That Support Better Metabolic Health   Langhana, Lightening Therapy   One of the first approaches in Ayurveda for metabolic disorders is Langhana, or “lightening therapy.” The goal is to reduce overload on the digestive system and give metabolism an opportunity to reset. This includes:   Eating lighter meals Avoiding overeating Choosing foods that are easy to digest Reducing processed and heavy foods Allowing proper gaps between meals   When digestion improves, the body becomes more efficient at handling glucose and insulin. Cells begin responding better to insulin signals, reducing metabolic stress.   Simple dietary practices can often create profound changes in energy levels, bloating, cravings, and metabolic function.   Ruksha Ahara and Ruksha Upachara, Dry Diet and Dry Therapies   Kapha imbalance is typically associated with heaviness, excess moisture, sluggishness, and fat accumulation.   To counter this, Ayurveda recommends “Ruksha” therapies, dry and light approaches that reduce excessive Kapha.   Examples include:   Barley Horse gram Flat beans Millets Light legumes   Daily use of spices such as:   Turmeric Black pepper Dry ginger Cumin Mustard seeds   can help stimulate metabolism and improve digestion.   These foods and herbs support better cellular activity and reduce stagnation in the body.   Ushna Dravya   Cold, heavy, oily, and refrigerated foods tend to aggravate Kapha and weaken digestion.   Warmth, on the other hand, activates Agni.   This is why Ayurveda often recommends:   Warm water throughout the day Freshly cooked warm meals Warm herbal infusions   These practices improve circulation, digestion, and metabolic responsiveness.   Many people notice reduced bloating, better digestion, and improved energy simply by shifting from cold foods and drinks to warm alternatives.   Bitter and Pungent Tastes for Metabolic Cleansing   Ayurveda classifies tastes according to their effect on the body.   For Kapha-related disorders like insulin resistance and obesity, bitter (Tikta) and pungent (Katu) tastes are especially beneficial.   Bitter substances help clear metabolic channels and reduce excess accumulation.   Pungent substances stimulate digestion and circulation.   Examples include: Neem Fenugreek (Methi) Bitter gourd Turmeric Black pepper Garlic Radish Leafy greens   These foods support healthy glucose metabolism and improve digestive efficiency.   Vyayama, Movement and Exercise   Modern lifestyles with very little physical activity are one of the main reasons behind poor metabolism and lifestyle diseases today.   Ayurveda strongly emphasises daily movement to reduce Kapha stagnation.   Exercise helps:   Improve circulation Enhance glucose uptake into muscles Reduce insulin resistance Improve cardiovascular health Support healthy body weight   Strength training is particularly beneficial because muscle tissue improves insulin sensitivity.   Even simple daily habits like walking after meals, climbing stairs, yoga, or mobility exercises can create significant improvements over time.   Consistency matters far more than intensity.   Udvartana, Herbal Dry Powder Massage   Udvartana is a traditional Ayurvedic therapy involving massage with herbal powders.   Unlike oil massage, this therapy uses dry herbal powders to stimulate circulation and reduce excess Kapha.   Horse gram powder is commonly used for this purpose.   Benefits may include:   Improved lymphatic circulation Reduction in heaviness Better skin tone Support for fat metabolism Increased body stimulation   This therapy is often used as part of comprehensive metabolic management programs.   Swedana, Sweat Therapy   Swedana refers to therapeutic sweating or steam therapy.   Mild heat therapy helps mobilise accumulated Kapha in the body.   Benefits include:   Improved circulation Relaxation of stiffness Opening of channels Better elimination of waste Enhanced metabolic activity   One important precaution: The head should not be exposed directly to excessive steam or heat during the process.   Deepana and Pachana, Improving Digestion and Reducing Ama   Ayurveda believes that weak digestion is the foundation of many chronic diseases.   When digestion is impaired, Ama forms in the body.   Ama contributes to:   Sluggish metabolism Inflammation Weight gain Blocked circulation Reduced insulin sensitivity   Deepana therapies stimulate digestive fire, while Pachana therapies help in digestion.   This may include: Digestive herbs Fasting strategies Herbal teas Spice combinations Meal timing corrections   Once digestion improves, many metabolic symptoms begin correcting naturally.   Shamana Therapy, Balancing Kapha with Herbs   After digestion improves and metabolism becomes more active, Ayurveda may use herbal formulations to stabilise the system. This is called Shamana therapy.   Importantly, Ayurveda does not rely on random single herbs for complex metabolic disorders.   Proper treatment usually involves carefully selected herbal combinations tailored to:   Body constitution Digestion Sleep Stress levels Weight… Continue reading Why High Blood Pressure Is Increasing in People in Their 30s and 40s?
