Saviez-vous que les intolérances alimentaires peuvent causer votre incapacité à perdre du poids?


Symptoms of food intolerance are often thought to be as direct as immediate diarrhea after consuming lactose. However, sometimes they can be as subtle as mild chronic fatigue.


Food intolerance is a reaction of the digestive system to a type of food that is eaten. During an allergic reaction, the immune system produces an IgE-type antibody (immunoglobulin E), which causes changes in the cells of the body. This imbalance causes the release of chemicals in the blood, which in turn cause allergic reactions in our body.

In terms of food intolerance, the presence of antibodies will be more of the IgG (immunoglobulin G) type, the latter reflecting a physiological state, a response of the immune system in response to exposure to food. These antibodies can cause inflammatory reactions, which can take up to three days to appear, making intolerances difficult to detect.

Symptoms of food intolerance can be as much digestive as physical. Here are a few examples:


  • Bloating & water retention
  • Flatulence
  • Inability to lose weight despite eating well and exercising
  • Headaches & migraines
  • Menstrual symptoms amplified
  • Chronic fatigue
  • Joint and / or muscle stiffness and tension
  • Decreased mental clarity or difficulty concentrating
  • Various dermatitis (eczema, rosacea, acne, etc.))
  • etc.⠀⠀⠀⠀⠀⠀⠀

When in suspicion, I recommend theeliminatory diet. This diet consists of withdrawing allergenic or irritant foods for 3 to 4 weeks. The foods are:⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Dairy products⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Eggs⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Shellfish⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Solanaceae (tomato, eggplant, potato, pepper)⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Nuts⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Wheat and corn⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Legumes⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Sweeteners⠀⠀⠀⠀⠀⠀⠀⠀⠀
- Sometimes pseudo-cereals

The goal of this diet is to allow irritants to rest for long enough to reduce symptoms. The rate at which symptoms decrease varies from person to person. The benefits will be greater when the diet is combined with a naturopathic protocol with specific nutraceutical support. Reintroduction is as important as the diet itself. It should be done slowly, one food at a time. When the reintroduced food causes a symptom or less improvement, it should be removed a second time for a period of 3 months.

Be careful, at no time should this diet last more than 3 months. Follow-up by a specialist is strongly recommended.

Note that it is also possible to do food intolerance tests.
