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.
�� What You'll Learn in This Video:
✅ Why people get “Ozempic Face” after extreme dieting or GLP-1 drugs
✅ The critical difference between subcutaneous fat (under the skin) and visceral fat (around
your organs)
✅ How fasting triggers growth hormone, autophagy, and fat-beiging to help preserve skin
elasticity and bone health
✅ Real-world examples: How fasting users look healthier compared to drug-induced weight
loss
✅ Why fasting helps your body burn harmful internal fat and retain healthy facial fat
✅ How brown fat activation boosts metabolism and supports long-term fat loss
✅ Key findings from recent clinical studies (2022–2025) on time-restricted eating, low-carb
diets, and belly fat reduction
