The Montignac Diet

The Montignac Diet was created by Michel Montignac and first gained popularity in Europe in the early 1990s. This diet regulates how individuals eat foods based on food combining and the glycemic index. The Montignac Diet boast that individuals can continue eating chocolate, wine, cheese and meat while still loosing weight. If individuals follow the meal plan provided on the Montignac Diet, they are supposed to be able to lose weight, reduce the risk of certain heart disease and control diabetes.

The Premise

The Montignac Diet bases the glycemic index portion of the diet upon research completed by the Laval University in Quebec and Harvard University. This diet is based on the belief that people have excess body fat because they eat fats or meats at the same time as certain carbohydrates. This creates a spike in blood glucose levels, which leads to fat storage.

On the Montignac Diet, food is grouped into four main categories:carbohydrates; lipids, such as fats and meats; carbohydrate-lipids, such as organ meat and nuts; and fibers, such as vegetables and whole grains. The Montignac Diet rates the glycemic index of carbohydrates. High-glycemic carbohydrates, such as refined grains, glucose, sugar and starchy vegetables should be avoided. When on the Montignac Diet, individuals are advised to avoid eating carbohydrates at the same meal as lipids. Carbohydrates and lipids should only be consumed three hours apart. On this diet, there are good fats and bad fats. Good fats include olive oil and nuts and bad fats include red meat and butter. Bad fats are to be avoided.

The meal plan on the Montignac Diet has dieters eating three meals a day. Snacking is limited. Fruits are not allowed to be combined with meals. Fruits are only allowed to be eaten separately, in between meals.

The Montignac Diet has two phases, a weight loss phase and a maintenance phase. During the weight loss phase, the meal plan supposedly helps detoxify the pancreas and helps prevent excessive insulin creation. This phase is to be followed for two months. The maintenance phase teaches dieters how to maintain their body weight.

The Montignac Diet allows for individuals to still consume many items that are forbidden on other diets, like cheese and chocolate. The meal plan on the Montignac Diet allows for dieters to personalize their eating plan. The Montignac Diet focuses on foods that have a high fiber content, which should help dieters feel full, longer.

Things to Consider

The Montignac Diet is similar to many other fad diets, like Adkins, because it recommends eating only low-glycelmic index carbohydrates. This diet does not recommend a low-calorie meal plan. Scientific research shows that the most effective method for weight loss is to follow a diet that promotes a meal plan where individuals consume fewer calories a day than their bodies burn.


While Michel Montignac states this diet is based on science, not all the theories he presents are supported by clinical studies in humans.  Despite this, compared to other low carbohydrate diets, this diet offers sensible eating principles, such as eating whole grain foods and avoiding fatty foods like red meats. In general, the Montignac Diet should not be harmful for dieters to try and some dieters may experience weight loss.

    I started my mother at the age of 91 on the Montignac diet as she weighed 169 pounds and was far overweight for her height. Her cholesterol for several years was in the 360 range.

    In one year she lost 25 pounds and her cholesterol dropped to 180. Her doctor was amazed…and her health was excellent. She continued to lose more weight until she reach 129. She maintained that weight from the age of 93 until she died at the age of 99 of an infection.

    Your site was interesting until you bought into the CALORIE myth…a completely disproven method of weight loss. Burning calories (a measure of heat) is real, but it has no relationship with calorie consumption. In fact, anyone who counts calories will struggle their entire life trying to lose weight or maintain a healthy weight.

    The calorie myth is why the world is overweight, especially in the UK and US. Here is a simple illustration of why considering calories makes no sense:

    Roast turkey 1 cup fat 7gr, calories 240. carb 0 protein 41
    One croissant fat 12 gr, calories 235 carb 27 protein 5

    If you compare those and believe somehow that because the calories are almost identical you can eat either and not change your weight, then you really don’t understand anything you read in the Montignac book. The croissant provides fat + carb which makes your pancreas work to store the fat while burning the sugars. You gain weight, your pancreas works overtime, and your cholesterol will go up. The turkey, with no carbs, is healthier as it combines high protein and less fat and will not put weight on nor affect your cholesterol. Calories play no part in the equation.

    Did you also know that high cholesterol comes from a high carb, high sugar diet? Not from fats. The newest findings (not fads – Montignac’s diet is not a fad, it is science), say to lose fat, eat fat.

    If you are sincere about weight loss which is the focus of your site, you might want to study the real facts about the introduction of the calorie myth by two doctors in 1930 whose research was limited and who didn’t understand that depriving a body of calories without consideration of the source of the calories, makes the body go into survival mode and store fat!
