The Obesity Code
Jason Fung · 2016
Nephrologist Jason Fung argues that obesity is a hormonal disorder of too much insulin, not a simple math problem of eating too many calories, and that the cure is to lower insulin through what you eat and when you eat, including intermittent fasting.
Popular reframing of weight gain around insulin and fasting, with a clear practical protocol.
Three of the ideas you’ll keep
The Clif summary of The Obesity Code pulls out 7 insights. Here are the first three.
- Stop counting calories and start lowering insulin: weight is controlled by hormones, so the goal is to reduce the insulin your food provokes, not just shrink portions.
- Cut added sugar and refined grains first, they spike insulin the hardest. Fructose is the worst offender because it drives fatty liver and insulin resistance directly.
- Eat real, whole food with its fat and fiber intact: dietary fat barely raises insulin, and the fiber in unprocessed carbs blunts the insulin spike that refined versions cause.
