Why Calories In Calories Oout always fails

Why does cutting calories often lead to a weight loss plateau? Is the traditional "Calories In, Calories Out" approach enough to explain weight gain and fat loss? In this video, Dr. Jason Fung explains why he believes the conventional calorie-counting model fails to address the underlying causes of weight gain. He explores the relationship between calorie intake, metabolic adaptation, insulin, hormones, and hunger—and why understanding these factors may provide a different perspective on sustainable weight management. In this video, you'll learn: ● Why the traditional Calories In, Calories Out model has limitations. ● How reducing calorie intake can be accompanied by changes in metabolic rate. ● The difference between calorie balance and the underlying causes of weight gain. ● How insulin influences fat storage and the release of stored energy. ● Why the type of food you eat may affect hunger, satiety, and energy. ● How an 800-calorie omelet compares with a sugary coffee and pastry breakfast in Dr. Fung's explanation. ● Why understanding the root causes of hunger matters more than simply counting calories. ● The three types of hunger: homeostatic, hedonic, and conditioned hunger. ● How GLP-1 medications such as Ozempic relate to appetite and hunger. 🔔 Subscribe to the channel for more science-backed health insights: https://www.youtube.com/@DrJasonFung EXPLORE THE HUNGER CODE Discover more about the science of hunger, appetite, and weight management in Dr. Jason Fung's book, The Hunger Code. 📖 Get the book: https://www.amazon.com/dp/1778401562 ABOUT DR.
