Stop counting calories. If ‘Calories In, Calories Out’ really worked, why do those diets fail 99% of the time? In this video, Dr. Jason Fung explains why obesity is not a caloric imbalance, but a hormonal imbalance—specifically involving insulin. Most people believe that weight gain is a personal choice caused by eating too much and exercising too little. But science tells a different story. Discover how your body’s internal thermostat (BMR) actually regulates your weight and why lowering insulin, not calories, is the key to long-term fat loss.
In this video you will learn:
- Why the ‘Calories In, Calories Out’ model is scientifically flawed.
- How damage to the hypothalamus leads to massive weight gain (independent of willpower).
- The role of Basal Metabolic Rate (BMR) in energy expenditure. ● How Insulin acts as a ‘Fat Storage Hormone’ and blocks lipolysis (fat burning).
- Why simply eating less lowers your metabolism and makes you regain weight.
