The Dangerous Cult of 'Fasting' Influencers. Fasting has its anecdotal benefits, yes. But it is overrated. And water fasting is highly overrated. But this video featuring a Cardiologist is amusingly nonsense. There is no study from Boston (from a "University?" - how vague!) that says 7-days water fasting reduces risk of cancer (what cancer?) by 70%. And there is no proof that fasting kills cancer cells in humans. Here is what fasting does to cancers in humans. Nothing. Fasting is now become a sort of religion-like cult for wellness influencers to rake in views and engagement. From a scientific standpoint, there are no realistically good human studies to prove anything from fasting that benefits cancers. I know, I know, "autophagy" and all that. Autophagy: Autophagy is the natural, conserved degradation of the cell that removes unnecessary or dysfunctional components. Yes, its a legit term and all. But in the context of cancer reduction and fasting in humans, it sounds like "immunity boosting," another wellness fraud term. The effects of fasting on cancer cells are all based on MOUSE studies, and none explicitly translated to humans. See this paper: everything is based on cells and tissues and small animal experiments: "While research on the subject is tantalizing, there’s little clinical evidence involving humans to substantiate the claims. Studies on the potential impacts on cancer treatment from various forms of fasting or calorie restriction, including the possibility that they reduce side effects, have been limited." "Fasting may not be appropriate for malnourished individuals or those with cancer cachexia, which results in a continuing loss of skeletal muscle mass, or for people with chronic diseases. Those with diabetes need to be very careful, because of the risk of hypoglycemia." "Based on our systematic review and meta-analysis, there is currently no evidence supporting the superiority of therapeutic fasting over non-fasting in preventing chemotherapy toxicity." - see here: Even intermittent fasting (IF) is overrated in cancer. "IF may be considered in adults seeking cancer-prevention benefits through means of weight management, butwhether IF itself affects cancer-related metabolic and molecular pathways remains unanswered. See here: Also this: "Fasting for short periods does not have any beneficial effect on the quality of life of cancer patients during treatment. Evidence on fasting regimes reducing side effects and toxicities of chemotherapy is missing." See here: The whole aspect of "fasting reducing cancer incidence" in the real world is just due to weight loss. Obesity is associated with at least 13 types of cancers and reversing obesity reduces risk of cancer - nothing to do with fasting killing off cancers cells in the body. And one can lose weight even without fasting. See here: Everything from prevention of adverse events of cancer, to reduction in side effects from chemotherapy, to slowing cancer growth by reducing glucose levels, to promoting cell regeneration by affecting autophagy is all LAB BASED MOLECULAR LEVEL HYPOTHESIS that has not been proven conclusively in humans. See here: Cancer patients must not starve. They must remain hydrated and they must eat a well balanced diet because cancer condition is highly demanding. And dont water fast for 7 days. Easy for people to make reels on it, but in real life, it may prove disastrous. Water fast does make you lose weight (because of starvation) but it is not at all a healthy way to lose weight. Stop with this fasting and cancer madness already.

The Science of Fasting - 2012 Documentary There is a reason so many religions and cultures across the world advocate for fasting to resolve health issues, and think every human being on earth should fast intermittently to help repair and detoxify themselves in this incredibly toxic world where we are being inundated from every vector. Obviously fasting can be detrimental if done excessively and the nutrition is inadequate in between fasting stints, but overall if done right, it's so obviously a great tool for our health that we should all take advantage of. It can by intermittent fasting with 18/6 or 16/8 schedules, it can be 1-2 days a month, it can be 1 week every 6 months, or whatever works best for your individual situation and health goals, but we should all be doing a little bit of fasting every now and again. Considering a large portion of the US is brutally addicted to food and severely overweight and unhealthy with countless diseases and ailments, we should be investing in fasting clinics such as the one shown in this documentary to help them break the addiction and get healthy. Robert F. Kennedy Jr has discussed detox clinics for drug abuse, and hope he can consider the same for obesity and chronic disease with fasting clinics. Many people are not disciplined and strong enough to not eat at home for a few days because of all the temptation, but if they had a place to stay with rules and restrictions, they could learn that discipline and then do it on their own. For anyone that thinks it's dangerous to fast for a long period of time, you should lookup the story of the scottish man back in 1965 who was over 450lbs and fasted for a year straight. If you have body fat on you, you can fast until it's gone, as long as you have water to drink.

A 72-hour water fast (drinking water but consuming no calories) can trigger several changes in the body. Some are well supported by research, while others are still being studied. Potential benefits 1. Autophagy may increase * Autophagy is the process by which cells break down and recycle damaged components. * Animal studies show fasting can stimulate autophagy, and in humans it is thought to increase during prolonged fasting, although exactly when and by how much varies and is still being researched. 2. Ketosis * After around 24–48 hours, most people begin producing ketones from stored fat. * By 72 hours, many people are in deeper ketosis, which can: * Increase fat burning. * Provide an alternative fuel source for the brain. * Reduce hunger in some people once ketosis is established. 3. Improved insulin sensitivity * Fasting lowers insulin levels. * Short-term fasting can improve insulin sensitivity after the fast, which may help with blood sugar regulation in some individuals. 4. Reduced inflammation * Some studies have found short-term fasting can lower certain inflammatory markers, although results vary. 5. Weight loss * You’ll lose weight during a 72-hour fast. * Part of this is fat, but a significant amount is also water and depleted glycogen stores. * Some weight is regained once you eat normally again. 6. Lower blood sugar * Blood glucose typically falls during fasting, particularly in people without diabetes. 7. Potential cardiovascular benefits * Temporary reductions in blood pressure may occur. * Triglycerides may improve in some people. * Long-term benefits depend more on overall diet and lifestyle than occasional fasting. 8. Mental clarity * Some people report improved focus and concentration after the first 24–48 hours, possibly related to ketone production. * Others experience fatigue or brain fog instead. 9. Digestive rest * The digestive system gets a break from processing food

Fasting is NOT Superior for Autophagy Autophagy has become the biggest buzzword in nutrition in the last 5 years & whenever I do videos or posts on intermittent fasting & why it is a useful tool for fat loss, but NOT superior to other calorie equated diets, people invariably say that ‘tHeSe StUdIeS dOn’T aCcOuNt FoR aUtoPhAgY!’ When I cite studies showing that normal calorie restriction gets the same benefits as calorie equated fasting diets, people often say that fasting gets you the benefits WITHOUT calorie restriction. Well, a very highly controlled study showed that this is NOT the case Well this study did (PMID: 34135111). They had people follow one of 3 diets: 1) Alternate day fasting without calorie restriction where they ate 200% of their maintenance calories on feeding days, & 0% the next day (200:0) & continued to alternate them throughout the course of the study 2) Alternate day fasting with 25% calorie restriction where they ate 150% of their maintenance calories on feeding days & 0% the next day (150:0) & continued to alternate those throughout the course of the study or 3) Continuous calorie restriction where they had people eat 75% of their maintenance calories every day for the duration of the study (75:75) Both the 150:0 & 75:75 diets reduced body weight to the same extent, but the 75:75 group lost slightly more fat mass & retained slightly more lean mass than the 150:0 fasting group. Both restricted groups lost more body fat & weight than the 200:0 group which did not lose weight or fat. Markers of autophagy were also equivalent between the 150:0 & 75:75 groups as well as other adipose tissue genes, gut hormones, and markers of cardiometabolic health This study demonstrates that it is the caloric restriction that drives these improvements in health & the changes in autophagy, NOT because fasting has some magical effect on autophagy that exists outside of the caloric restriction it imposes I am NOT saying fasting is bad. I’m not saying it’s not a useful tool or that you can’t lose fat with it. You can & it can be a great tool for many people… it’s just not magic like many proponents of fasting try to make it out to be Tired of the diet wars & not knowing how to make sense of all the contradictory information out there? Comment ‘FRAMEWORK’ and I’ll send you my simplified guide on how to lose fat & build muscle for FREE
