Fit for Life by Harvey and Marilyn Diamond

A classic food-combining lifestyle programme

Good Condition – visible cover wear with edge and corner scuffing.

Fit for Life presents Harvey and Marilyn Diamond’s influential programme for weight management and wellbeing, built around their ideas about the body’s natural daily cycles, food timing and food combining. The authors encourage a diet rich in fresh fruit, vegetables and other high-water-content foods, while proposing specific ways to separate proteins and carbohydrates and structure meals across the day. Recipes and practical suggestions aim to make the system usable without calorie counting or an extreme exercise regime. First published in the 1980s, the book became a major popular diet title, although several of its nutritional claims remain disputed by mainstream health professionals. It is best read as a landmark lifestyle programme whose recommendations can be considered alongside current evidence and personalised medical advice.
