Two doctors want to help people lose weight, and they know how to do it. Obesity is now our biggest health threat and is ruining people’s lives. Diets work for a while, but then fail. Why?

In The Diet Whisperer, Dr Paul Barrington Chell and Dr Monique Hope-Ross explain in simple terms why we are now struggling with our weight. And the answers are very surprising. They tell us why calorie counting is flawed, and why exercise is not the answer. They dispel many long-held myths about weight loss and dieting, backing up their methods with up-to-date evidence-based medicine. In this remarkable book on wellness, the two doctors tell us exactly how to lose weight, lose it quickly, and lose it forever.

There are easy to follow plans, for fat adapting our bodies and controlling our fat storage hormones. They teach us how to combine these with safe intermittent fasting, to control our weight forever. As a new diet-whisperer, you will have the skills to make your loved ones healthier too.

Dear Dr Monique, I have just commenced week 9. So far I have lost 18 lbs! I think I think that is my optimum weight now, I am 5'4" and am now 9 stone and I feel wonderful. So full of energy and full of joy. have not felt like this for years! I was a vegetarian for many years thinking it was the "right" thing to do for me and for the planet. But I was always bloated and constipated and hungry! Now I eat meat (only ethical) and have never felt so well. Thank you so much for all that you and Dr. Paul do.

The Diet Whisperer
The Secrets of Permanent Weight Loss

This book is now out of print

Try The Diet Whisperer 12-Week Reset Plan

As doctors, Paul and Monique have been advising patients on weight loss and metabolic wellness for decades. When many patients lost weight permanently and reversed their type two diabetes (T2D), they wrote a book about their journey. The book on weight loss is called The Diet Whisperer 12-Week Reset Plan, a much-updated version of their first book. In just 12 weeks you can see your whole life turned around, with up to 12 kg (26 pounds) of weight loss. You will feel so much better and be back in control.

Part 1. The road to Obesity. As doctors Paul and Monique found most people (including most doctors) do not understand why our bodies gain weight. From the book you learn exactly why you put on weight, and this becomes your first cornerstone of success.

Part 2. The Road from Obesity. Paul and Monique take the responsibility for your learning. You learn the secrets of weight loss and how you can nudge your fat storage hormones into giving up your body fat. This is all explained in simple terms, and you will learn how to teach your body to become ‘fat adapted’, torching the fat as you go. There is a whole chapter dispelling the many ‘diet myths’, that most people still hold as true. You will be shocked. There are plenty of Eureka moments through the book when the penny suddenly drops, and you gain a new understanding of your own body. This is the second cornerstone to your success.

"I found this book full of information regarding how our bodies, particularly our own hormones, can work against us. It gives information on how to change your food habits to enable you to take back control of your body weight and mental well-being. As a rheumatoid arthritis sufferer, I was particularly interested in how changing my eating habits would reduce inflammation. A very interesting and informative book I would highly recommend."
