The Obesity Code

The Book

Calories in, calories out is a lie. Fung is a nephrologist who lays out the hormonal model. It's insulin. It was always insulin.

Heavy on the science, but readable. He walks through every major diet study and shows why they all failed for the same reason. Then he gives you the fix, and it's embarrassingly simple. The food industry won't like this one.

Key Takeaways

• Cortisol raises insulin. Stress makes you fat, independent of diet
• Vinegar and fibre lower the insulin response of a meal
• The solution is simple: eat real food, don't snack, and occasionally don't eat at all
• Insulin resistance is the root. Everything else is downstream
• Fasting isn't starvation. Your body is designed for it. Three meals a day is a marketing invention
