The Obesity Code (Jason Fung)

The Obesity Code by Jason Fung explains that weight gain is primarily driven by insulin levels, which regulate fat storage. High insulin, often caused by frequent eating and high-carb diets, signals the body to store fat. To lose weight, it’s important to control insulin through strategies like intermittent fasting and reducing carbohydrate intake, rather than just counting calories. The book emphasizes understanding hormonal regulation, especially insulin, to achieve sustainable weight loss and improve overall health, challenging the traditional calorie-focused approach.
