The menus at the back of this book offer plenty of filling and tasty recipes for making up 800-calorie days. They are all based on a low-carb, high-protein Mediterranean-style approach. The reason I am so keen on this way of eating is that it will help you maintain your muscle mass and stop your metabolic rate from crashing as you lose weight.

The organ meats tend to be the fattiest parts of the animal. By focusing almost exclusively on the muscles of animals for food, we are preferentially eating protein rather than fat.

On the most basic level, only two things matter: the calories you eat and taking in some balance of macronutrients—proteins, carbs, and fats. The manipulation of those macronutrients and calories on a daily, weekly, or monthly basis is the special sauce that allows for progress.

“I’m no angel. I still have takeaways, wine, cheese, beer. I have a special black shirt that used to fit like cling film. I put it on every so often to see if it still fits. As long as it fits I’m doing fine.”
