Low in carbohydrates and high in fat, when we want to lose weight?
Profile : High in fat and low in carbohydrates
Principle : Limit all carbohydrates (starchy foods, sugary foods, fruits) and focus on fats. The goal is to reduce glycogen stores (sugar) to produce ketone bodies as an alternative energy source.
- Strong points :
- Rapid weight loss through mobilization of body fat
- Weak points
- Possible deficiency in certain minerals and vitamins when the Rapid Tone Diet
is strict, constipation, potential risk of kidney stones
- Binding and restrictive
What is the ketogenic Rapid Tone Diet
The ketogenic diet is a diet low in carbohydrates and rich in lipids that deviates from human consumption habits and recommendations for the general population.
Since 2006, Nutrition has recommended the following percentages of calorie intake: 40 to 55% for carbohydrates, 30 to 40% for fats (lipids), and 15 to 29% for protein .
For their part, after having long advised a Rapid Tone Diet very rich in carbohydrates (50 to 55%), and low in fat (30 to 35%) French health authorities have recently made recommendations that are similar to those of LaNutrition, 40 55% of caloric intake in the form of carbohydrates, 35 to 40% in the form of lipids and 10 to 20% in the form of proteins.
But in the ketogenic Rapid Tone Diet we are talking about 70 to 80% of lipids, 20 to 25% of proteins and 5 to 10% of carbohydrates (20 to 50 grams of carbohydrates per day).
This mode of diet restricts carbohydrates to force the body to use lipids as a source of energy, to make ketone bodies (acetoacetate, beta-hydroxybutyrate) and therefore to achieve ketosis (when the body mainly uses ketonic bodies as source energy). Ketosis has therapeutic effects : besides epilepsy, it could be useful against diabetes ; it is also used to treat certain cancers and neurodegenerative diseases (Parkinson, Alzheimer). The mechanisms of action are no yet clear.

For the little story
At the time of ancient Rome, it was considered that the epileptics were inhabited by the demon. They were locked in a room for a few days without food, and the patients were improved. Over the centuries, fasting has become a method of treating epilepsy, with its disadvantages: we can not starve a patient to cure him permanently.
In 1921 the American doctor Russell Wilder sought to reduce or even eliminate seizures in children with epilepsy without fasting. He found that a very fat diet leads to the production of ketone bodies as in fasting. And the diet has been successfully used in this indication until the development of drugs against epilepsy in the late 1940s.
The ketogenic diet regained interest in the 1990s, especially to treat children who remained refractory to epilepsy drugs. Today the applications of this diet are more numerous and the studies are multiplying.
