Who of those who is 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 - oh-la-la! Figure as in the picture! In fact, everything is not so simple and we have to understand the pros and cons of dietary supplements for weight loss.

What are dietary supplements?

Weight loss supplements are biologically active additives intended for direct intake with food. Most often they contain vitamins, trace elements, plant extracts or even pharmacologically active substances. These are drugs that have not yet passed clinical trials, but are certified for implementation by a wide range of consumers. Recipe for buying dietary supplements do not require.

We will consider different groups of these substances by the mechanism of their action:

1. The first group of dietary supplements contains components that reduce appetite by affecting the centers of saturation of the central nervous system. Such weight loss pads can contain dietary fibers that swell in the stomach and at the same time mechanically create a feeling of satiety or contain various seasonings. It is necessary to carefully study the composition of the drug, because in such dietary supplements unscrupulous manufacturers sometimes add pharmacological substances that suppress the appetite of the central genesis. Most often, it is sibutramine, which has a number of side effects and contraindications, for example, pregnancy, lactation, sleep disorders, increased nervous excitability. It is proved that it is in many means for losing weight.

Take such dietary supplements for weight loss is necessary only after consulting a doctor.

2. Preparations that increase the processes of fat in the cells, the so-called "fat burners", or effective dietary supplements for weight loss. Often such preparations contain foskoline, caffeine, tannin, adrenaline, vitamins and trace elements. But, buying on advertising, those who want to lose weight without effort begin to eat without restrictions, and this only leads to weight gain. Some fat burners, for example, L-carnitine, work only in the right combination with physical activity. In other cases this is just an expensive "dummy".

3. The third group can include substances that violate the absorption of fats. The mechanism of their action is diverse:

- bind the lipids that come with food in the gastrointestinal tract into complexes not digested for the body;

- increase the release of water from the body, that is, a weak diuretic effect;

- accelerate the passage of the food lump in the intestines, thereby violating the full absorption of nutrients.

The very best dietary supplements contain completely natural ingredients. Most popular recently:

- L-carnitine is a vitamin-like amino acid that stimulates the oxidation of fatty acids, besides it is synthesized in the human body. In physiological doses it is absolutely safe even for an infant;

- Chromium picolinate reduces cravings for sweet, normalizes carbohydrate metabolism, stimulates the breakdown of glucose with the release of energy, rather than depositing it into fat stores;

- Chitosan reduces the absorption of fatty acids from food in the intestines, thus normalizing the level of cholesterol;

- extract of green tea increases metabolism, endurance to physical activity, regulates glucose level;

- Extracts of grapefruit, pineapple, Garcinia Cambodian help break down fats, reduce appetite, increase basal metabolism, have antioxidant effect.
