The Body Clock Diet 9/10

By Dietitian Juliette Kellow BSc RD

What’s the theory?

This book is based on the premise that it’s not just what you eat but when you eat it that counts when it comes to losing weight.

The Body Clock Diet aims to keep you in sync with your body’s circadian or natural rhythms. These are controlled by your in-built body clock and affect your sleeping patterns, metabolism, appetite and energy levels.

By eating regularly, timing your meals to suit your body clock and getting the right balance of nutrients at each meal, you’ll work with the chemical reactions in your body that help regulate and control feelings of hunger and fullness.

What does the diet involve?

It couldn’t be more straightforward. You simply follow the 14-day plan. Each day includes three meals and two snacks. Plus there’s a 7-day vegetarian plan.

What can I eat?

The diet is based on a healthy, balanced diet that includes plenty of starchy carbs, fruit, veg, protein-rich foods and low-fat dairy products.

What else does the book include?

There’s a questionnaire to help you identify how your body clock ticks, plus a good explanation of how our body clock works, general healthy eating advice and recipes for each day.

How much weight will I lose?

Up to 2lb a week.

Juliette’s verdict on the Body Clock Diet

This plan is written by a dietitian, which explains the healthy approach it takes to losing weight.

It’s great to see a book that considers the impact our body clock has on our weight and it’s very easy to understand.
