Summary
Most people are told that “weight loss = calorie deficit.” But the truth is, a caloriedeficit is a myth. Your body is not a simple calculator where you just subtractcalories and lose fat. In this video, Dr. Jason Fung explains the science behindwhy focusing only on calories fails, and why hormones, insulin, and fatmetabolism are the real keys to healthy and lasting weight loss.When people try extreme dieting or drug-induced appetite suppression, theyoften experience side effects like the dreaded “Ozempic face” — hollow cheeks,sagging skin, and an unhealthy look. This happens because subcutaneous fat(the fat under the skin) gets burned instead of visceral fat (the dangerous fataround your organs). The result: you may lose weight, but you don’t look or feelhealthy.Fasting works completely differently. Instead of just cutting calories, fastingchanges your hormones and metabolism:�� Insulin drops, allowing fat burning to start�� Growth hormone rises, protecting muscle and skin elasticity�� Autophagy activates, repairing tissues and preventing loose skin�� Visceral fat is targeted, which improves health and appearance�� Brown fat (through beiging) is activated, boosting metabolism naturallyThat’s why people who fast look healthier, stronger, and younger compared tothose who follow harsh calorie-restricted diets.In this video you’ll discover:✅ Why calorie restriction almost always fails✅ The science of subcutaneous vs. visceral fat✅ How fasting avoids the “Ozempic face” problem✅ The role of hormones in fat burning and aging✅ How fasting improves skin health, prevents sagging, and supports long-termfat loss�� If you’re serious about losing weight without losing your health or youthfulook, this video is a must-watch.�� Subscribe now for more science-backed videos on fasting, w…
