"Why we get sick" by Benjamin Bikman. It talks about the causes and effects of insulin resistance, including how to diagnose it. "The obesity code" by Jason Fung. It talks about the causes of obesity (spoiler: hyperinsulinemia) and provides practical advice on how how reducing carbohydrates and intermittent fasting can help. "The case for keto" by Gary Taubes. Is an enjoyable read that not only covers the extensive evidence of how excess insulin leads to gaining body fat, but also how we ended up culturally terrified of dietary fat and dietary cholesterol. If you have already managed to become lean through a low-carbohydrate diet and/or intermittent fasting, then I do recommend following the peer-reviewed research published by Nicholas Norwitz (he also has a YouTube channel for laypeople). Ultimately, what leads me to this eating pattern is my own difficulty managing my body weight when I don't. If I could stay lean, healthy and satiated with a mixed diet that included some rice, bread, potatoes and pasta, I would go for it. Many people do just fine with some carbohydrates in their diet. I used to as well, when I was younger. These days, I can either take significant steps to reduce my insulin levels or I slowly creep towards obesity and metabolic syndrome.
