Which of those who are overweight would not want to lose weight quickly, easily and effortlessly? Many of these people believe in the miraculous properties of drugs such as dietary supplements for weight loss. I drank a couple of packs of pills and - o-la-la! The figure is as in the picture! In fact, everything is not so simple and we have to figure out the pros and cons of dietary supplements for weight loss.
What are dietary supplements?
Dietary supplements for weight loss are dietary supplements intended for direct intake with food. Most often, they contain vitamins, minerals, plant extracts, or even pharmacologically active substances. These are drugs that have not yet passed clinical trials, but are certified for sale to a wide range of consumers. Recipe for the purchase of dietary supplements do not require.

It is necessary to carefully study the composition of the drug, because unscrupulous manufacturers sometimes add pharmacological substances that suppress the appetite of central origin to such a dietary supplement. Most often, this is sibutramine, which has a number of side effects and contraindications, for example, pregnancy, lactation, sleep disturbances, increased nervous irritability. It is proved that it is in many means for losing weight.
To take such dietary supplements for weight loss is necessary only after consulting a doctor.
2. Drugs that increase the processes of fat breakdown in cells, the so-called "fat burners", or effective dietary supplements for weight loss. Often, such preparations contain foscolin, caffeine, tannin, adrenaline, vitamins and minerals. But, having bought advertising, those who want to lose weight effortlessly begin to eat without restrictions, and this only leads to weight gain. Some fat burners, such as L-carnitine, work only in the right combination with physical activity. In other cases, this is just an expensive “dummy”.
3. The third group includes substances that violate the absorption of fats. The mechanism of action is diverse:
- bind lipids that come with food in the gastrointestinal tract into unassimilable complexes for the body;
- increase the release of water from the body, that is, a weak diuretic effect;
- accelerate the passage of the food lump through the intestines, thus violating the full absorption of nutrients.
The best dietary supplements for weight loss contain completely natural ingredients. Most popular recently:

- chromium picolinate reduces cravings for sweets, normalizes carbohydrate metabolism, stimulates the breakdown of glucose with the release of energy, and not its deposition into fat stores;
- chitosan reduces the absorption of fatty acids from food in the intestines, thus normalizing cholesterol levels;
