By establishing the bases of a new dietary philosophy, Michel Montignac has proven for more than 20 years that our choice of foods is determining factor on our health.

Simply adjusting our eating habits can help us not only shed excess weight, but also prevent metabolic diseases such as diabetes and heart disease.

The Montignac method proves that the energy factor is not decisive in gaining weight and what is important in a food is more its quality than its quantity of calories.

So, losing weight does not mean eating less but eating better, by choosing foods based on the metabolic effects they can produce. This means that by choosing "good" carbohydrates and "good" fats metabolism orients the meal's energy towards burning and not storage.

This book is divided into two parts, the first explains what the glycemic index (GI) is and how its use is a decisive factor for permanent weight loss. The book then features tables of the glycemic indexes of foods.
