The fact that the grapefruit diet is very helpful, knows probably everyone who has ever tried to deal with the extra (or not entirely superfluous) kilograms. Many people have long seen this as an axiom, although the studies that led to the well-founded conclusions that grapefruit can really help to lose weight, have been carried out a few years ago.

The first diet, which can be categorized as the Grapefruit Diet, appeared in the 1930s in the United States - when it was known as the Hollywood diet. There are two basic versions of it for a duration of seven days and 21 days. Both diets were very low calorie: a person who has chosen this diet could eat only a few products other than black coffee and grapefruit - for example, fresh vegetables and a little meat without visible fat. The results of such diets are not allowed to reveal any properties grapefruit diet - people who hold such a rigid eating plan, lose weight would be in the case if, instead of grapefruits they ate apples, oranges, and other fruits.

Diet of the Great Depression Depression - a little more than a bad mood   It bears little resemblance to the modern grapefruit diet - for example, the fact that now they do not involve the use of unlimited coffee.

How useful grapefruit diet?

Firstly, it is necessary to dispel a very widespread and seductive myth about the ability of grapefruit to burn fat deposits. In fact, the grapefruit does not burn fat, so you should not rely solely on losing weight at him.

Second, he can still contribute to weight loss, which was confirmed by the results of several studies. In 2004, an experiment was conducted, which lasted 12 weeks. It was attended by 91 people; Researchers subjects randomly divided into four groups. Members of the first group throughout the study before every meal took a placebo capsule Placebo - an effective tool for self-hypnosis And drank 200 grams of apple juice, the members of the second group received capsules with an extract of the seeds and peel a grapefruit, and washed down with them 200 grams of apple juice, the members of the third group took a placebo and drank 230 grams of grapefruit juice before meals, and the subjects of the fourth group received a placebo and ate half a fresh grapefruit. By the end of the twelfth week of the subjects that are in one way or another took grapefruit, it was noted a significant reduction in weight than those that took a placebo and drank apple juice. At the same time the most weight decreased in those who before meals ate fresh grapefruit. During the study, patients did not change their diet, but they had to make a half-hour walk, at least three times a week.

There have been other studies, during which it was confirmed that grapefruit helps to lose weight. But how does it work? Most researchers believe that the composition of grapefruit have unique chemical compounds which reduce the level of insulin in the blood. The relationship between insulin levels and obesity is complex, multifaceted and, probably, scientists have yet to learn about it a lot.

According to date data, elevated insulin levels The principles of action of insulin - the science of saving lives Firstly, it may mean that the body is not effectively using sugar as an energy source, because of which increases the likelihood that he will be postponed "in reserve" as subcutaneous fat. Secondly, because of the high levels of insulin hunger comes more quickly and is more powerful than people with normal levels of the hormone. Finally, elevated levels of insulin slows lipolysis. Putting all these factors together, it is easy to see why the lowering of insulin promotes weight loss. However, it is not known what kind of substances in grapefruit encourages weight loss, and at this point his ability to influence the level of insulin - just one of the most likely theories.

There are also opinions that grapefruit helps to lose weight just because it contains a lot of water and fiber, and at the same time - very few calories. After eating half a grapefruit or before a meal, a person partially saturated, as a consequence - eat less and therefore lose weight. This is often explained by the effectiveness and popularity in recent recommendation eat grapefruit diet overnight. Obviously, he does not burn fat deposits, while the person is sleeping, but it helps to moderate your appetite and avoid high-calorie snacks at night, which, incidentally, leads to excess weight faster than a hearty breakfasts and lunches.

Be that as it may, even if there is no magic in grapefruit substances that reduce insulin levels, the experience of thousands of people confirmed in the course of scientific research shows that grapefruit diet more effective than the same diet without grapefruit.

Features of action of levocarnitine is that simultaneously with the intensification of the process of obtaining energy from fat suppressed toxic effect of the decay products of fats and increases the tissue tolerability of action of toxic substances. That is a partial transition to energy from fat (normal energy derived from carbohydrates and fat - it is the body's energy reserves in the event of famine) has no negative effects on the body.

L-carnitine is capable of lowering the content of cholesterol in the body and slow down the formation of vascular atherosclerotic plaques.
