Dr. Jason Fung reveals the science of facial fat loss, subcutaneous vs. visceral fat, and how to lose weight without damaging your appearance. Have you ever seen someone lose a lot of weight but end up looking tired, old, or even sickly? You might’ve heard the term “Ozempic Face” — a phrase describing the hollow cheeks, sunken eyes, and wrinkled skin people often get after rapid weight loss through appetite-suppressing drugs or extreme calorie restriction. But here’s the good news: Fasting doesn’t cause Ozempic Face. In fact, it can protect your facial appearance while helping you lose dangerous internal fat and reverse metabolic diseases like type 2 diabetes.
In this powerful video, Dr. Jason Fung breaks down the real science behind facial fat loss and explains why intermittent fasting is a healthier, smarter, and more natural way to lose fat — without compromising your skin, face, or youthfulness.
