What is chrononutrition®?

Chrononutrition® is not a diet but a way of food rebalancing. It will allow you to lose or gain weight and to reach a well-balanced body shape.

All foods are allowed, provided they are eaten in the right quantity at the right time!

Eating well and ensure to providing the right quantities of all the essential elements necessary for our body would reduce the appearance of a large number of diseases.

Chrononutrition® is not only a way to control body shape and weight, but also to control cholesterol metabolism and non-insulin-dependent diabetes.

Based on nutrition, chrononutrition® is a method developed by Dr. Delabos with Professor Jean-Robert Rapin. It allows any individual (man, woman, child or elderly person) to regain a balanced figure, by losing or gaining weight, considering that any food is beneficial if it is consumed while respecting the Biological clock of our body.

Chrononutrition® is not a diet (with the “yo-yo” effects that often result from it), is not restrictive and does not involve deprivation. You can eat almost all food – you can continue to eat French fries, chocolate, cheese, butter –only if you respect the times and quantities! Your program will also be adapted if you have cholesterol, diabetes, …

Chrononutrition® is the application to the modern human beings of the thousand-year-old nutritional criteria that civilization has caused them to lose.  In this way, it adapts very precisely to the chronobiology of the body.

Studies by palaeontologists show that the primitive human being was carnivorous and fructivore and, governed by his instinctive impulses, followed a daily and seasonal feeding pattern that ensured his survival. He was a hunter and gatherer, conditioned for it:

  • drink when you get up;
  • hunt and kill his prey. Eat offal first (high fat) and then entrails (filled with pre-digested plants rich in slow sugars if they were herbivorous animals). Then eat the muscles (rich in protein), after leaving them in the air, wind and sun;
  • collect fruits, seeds or roots when appetite reappears.

So he ate fat in the morning, dense at noon, sweet in the afternoon.

Of course, our lifestyle has changed significantly, particularly due to prolonged and more intense activity, requiring the appearance of an evening meal and the modification of the afternoon meal.

While improving our living conditions no longer requires such high energy expenditure to fight against the cold, heat and all the hazards of a hostile environment, we deploy at least as much energy every day in longer and equally stressful activities. The modern man will therefore eat fat in the morning, dense at noon, sweet in the afternoon and light in the evening.

We have previously seen that chrononutrition® is based on the biological rhythms of the human organism. Here is in more detail what scientific studies have shown:

In the morning

  • High secretion of lipases to metabolize the fats that will be used to make the cell walls
  • Secretion of proteases to metabolize the proteins necessary for the development of cell structures
  • Insulin secretion and initiation of the use of slow sugars to gradually ensure transfers


  • Secretion of proteases and amylases
  • Assimilation of cellular proteins
  • Storage of protein reserves and defence globulins

In the afternoon

  • Appearance of an insulin peak allowing the use of fast and semi-rapid sugars to avoid protein destocking and compensate for fatigue related to organ function

In the evening

  • There is much less digestive secretion, which considerably slows down the assimilation of food. The body, attacking its period of cellular restructuring, will no longer be able to metabolize excessively rich nutritional intakes. However, what is not metabolized is stored!

The need for ever-increasing food due to population growth and cheap food has led food manufacturers to constantly increase their production.

Soil depletion, among other things, due to overexploitation, has consequences on the nutritional quality of our food. Hence the need for a supplement to compensate for vitamin and nutrient deficiencies.
