The number of diets that people use recently is difficult to calculate. Their diversity suggests that the science of dietetics "walks" at a fairly rapid pace and leads a large number of people wishing to maintain a healthy lifestyle.
Not so long ago it became known that some fruits and vegetables we love have a valuable effect on the body - they burn fats. Consequently, they can be used in dietary nutrition. So, for example, it happened with grapefruit. More recently, this bitter fruit was not, it can be said, "adopted" by doctors involved in the development of diets. But physiologists, having measured the calorie content of grapefruit, and also having studied its effect on the body, came to the conclusion that this representative of citrus has a huge range of useful properties. For example, the substance in its composition (flavonoid naringenin) is a biostimulator for the liver, which in turn increases the release of bile, which is the destroyer of fats.
The low calorie content of grapefruit is usually due to the fact that its composition, with recalculation of 100 grams of the raw product, contains very little (0. 9 g.) Proteins, (0. 2 g.) Fats and a fairly small amount of sugars (6. 5 g.). If you look at the data of the energy value table and compare its calorific value with other fruits, you can see the bright difference of this hybrid, characterized by the fact that it has the lowest calorie content, which is only 35 kilocalories per 100 grams of weight. Even ordinary rowan has this value twice as large. Inferior to the grapefruit is only a lemon, which has 31 calories. Undoubtedly, as soon as scientists learned the exact caloric value of this fruit, they decided to use it in dietary nutrition. And recently there have been many people who want to lose weight, while not straining themselves with hunger or complicated dietary delights. For such people, just the diet is based on a grapefruit. It is not complex in its application, it is efficient and quite accessible. Although the cost of this fruit now, does not indulge in cheapness. But, as they say in the people - health is more expensive.
In conclusion, it can be said that its extremely low calorie content is just a signal to go on a diet, and especially to those who need it. After all, there are many examples in the world of how this dietary fruit made weight loss a reality.
