Calorie blocker – a list of drugs for weight loss, composition and instructions for use

The content of the article

All products designed to reduce weight are advertised as dietary food additives because they contain natural ingredients. A calorie blocker is a drug that prevents the alpha-amylase enzyme from carrying out the process of converting complex carbohydrates into simple ones. Since simple sugars, in the absence of the need for muscles and internal organs, are deposited on the sides and abdomen in the form of fat folds, this principle of action of the drug looks quite reasonable.

What is a calorie blocker?

People’s desire is anything, while pharmacists have long known this without gaining excess weight and have been operating since the end of the 20th century. Chemists learned about the property of extracts from white bean pods to prevent starch from being digested in the gastrointestinal tract. Then the first fat blocker was made on the basis of the bean shell extract. This is really a natural remedy, because the drug does not contain chemically synthesized substances, so advertising here is telling the truth. However, how substantiated are claims that the supplement blocks calories?

Calorie Blocker Action

In laboratory conditions, bean extract proved to be excellent – in test tubes, gastric juice did not affect starch, it did not break down into simple components. Therefore, it was decided that complex carbohydrates would be excreted from the body without being absorbed, while it would be possible to lose weight without any effort. However, in an experiment on living organisms (experiments were performed on mice), the mechanism of action of carbohydrate blockers was different. The mice initially lost weight, but then, even with increased administration of the blocker, they compensated for the lost weight.

What caused such a real effect? After much research, scientists came to the conclusion that, over time, the gastrointestinal tract adapts to the drug, neutralizing its effect by increased production of alpha-amylase, which breaks down starch. That is, taking the drug on an ongoing basis is simply useless for losing weight; for calorie loss, the blocker can be effective only in the initial stages of taking.


The components of dietary supplements that contribute to body shape can be different. Traditionally, the composition of the calorie blocker contains an extract from legumes (phaseolamine), since it does not allow carbohydrates to break down, that is, it produces a short-term effect of getting rid of excess weight. Recently, additives based on chitosan, a substance derived from mollusk-like shells, have appeared on the pharmaceutical market. The mechanism of its action is based on the fact that this substance does not allow fats to be absorbed into the intestinal walls, blocking them and removing them from the body.

Doctors leave a lot of negative reviews about chitosan as the main component of the diet, indicating to the manufacturers that although the blocker does not allow a small amount of fats and calories to linger in the body, however, one tablet is too little to neutralize all the fats in the intestines. An increase in the amount of chitosan per tablet will also not bring benefits, because not only fats, but also carbohydrates create fat mass in the body.

Side effects

The most common unpleasant consequences of taking supplements aimed at weight loss are bloating and flatulence associated with fermentation processes in the intestine due to the large amount of undigested carbohydrates and fats. In this case, gas formation begins in the intestine. A large amount of water and gas causes the following side effects of fat blockers:

  • Diarrhea after each meal.
  • Sensation of nausea, heartburn associated with blockade of the enzymatic system of the stomach.
  • Violation of metabolic processes associated with the intake of vitamins D, A, E, iron and calcium. The absorption of these substances occurs only in conjunction with fats, and fats are excreted from the body. The consequence of this is anemia, brittle nails, skin allergic rashes.
  • Intervention in the digestive process with the blocking of individual enzymes can lead to a deterioration of the immune system, which is fraught with exacerbation of chronic diseases.
