I can report after 2 months, it really works. He recommended I start doing 8/16 fasting, and when I asked for reading material to learn about it, he recommended this book. This book was recommended to me by my doctor, as I did some bloodwork which said I high slightly high cholesterol and should lose 10 pounds. To do that, we have to lower our insulin levels, by eating less things that make them spike.

To change our weight, we have to change our 'body set weight' first. This evolutionary survival strategy has a single purpose: to make us regain the lost weight.'īasically, our bodies are like thermostats in our houses - they are set to a certain weight, and our bodies do their darnedest to keep our weight there. Weight loss results in increased hunger and decreased metabolism. Second, hormonal hunger signaling is immediately and indefinitely amplified in an effort to acquire more food. First, total energy expenditure is immediately and indefinitely reduced in order to conserve the available energy. 'Losing weight triggers two important responses. Shocker, I know, because again intuitively we all know that - its easy to go on a diet and lose weight, but then it always comes back. To prove this, the book goes into all the data it could find about weight loss studies done, and found that generally, diets don't work. The kind of calories make all the difference. This theory of calories in minus calories out, has prevailed for 50+ years, and the book makes a good case for it being wrong. Obesity can also be 'genetic' and passed to kids in the sense that if a mother has high insulin levels it will be passed to the child.Ī fascinating part of the book was that while many of us would intuitively say sugar and processed carbs are the culprit, the prevailing wisdom by all official sources is different - eg look at what the NHS website says: 'Obesity is generally caused by eating too much and moving too little.'. The foods that contribute to weight gain are largely a result of too much sugar and too much refined carbohydrates. Exercise is 5% of it (I would have said it was 70/30, so this was interesting). High insulin levels are a direct result of poor diet, and are 95% of the cause of obesity. High insulin levels are responsible for obesity, and to a smaller degree, so can high cortisol levels (being overly stressed can lead to weight gain). The main theory of the book is that the root cause of obesity and weight gain is a complex hormonal imbalance, that stems from high blood insulin levels. Highly recommended for everyone (the title is misleading, its not just for obese people). Well backed with science and uses studies to make all his points. The best book about how to eat healthy and the reasoning behind it that I've yet read.
