Under the word diet should be understood as a properly organized food, thanks to which you can feel good and not gain excess weight.
But over time the term diet has acquired other shades, and today it means something like "shock therapy" when it is necessary to lose a certain number of kilograms in a short period of time.
Today there are a lot of fast diets. They are based on the use of a particular type of product or caloric restriction, as well as exclusion from the diet or fats, or proteins, or carbohydrates. Diet can also have a negative effect on the body.
The most famous express diets are:
Protein diet
The essence of the protein diet is to exclude all carbohydrates and switch to the use of protein products. There are many options for this type of diet, but mainly low-fat meat and fish, eggs, fat-free cottage cheese, kefir, as well as mineral water, green tea and unsweetened coffee are recommended for food. In order to maintain a balance of vitamins in the diet, you can turn on grapefruit. The effectiveness of the protein diet is expressed in the excretion of the body fluid, as well as in the fact that when a deficiency of carbohydrates the body begins to extract energy from proteins. The diet is strictly forbidden to spend more than 3-5 days. Despite the fact that she is not hungry, but because of a shortage of carbohydrates a person can suffer from a headache, experience weakness, lose concentration, because the brain needs energy.
Monodiettes
The essence of mono-diet is the use of one product for several days. Strict mono diets are built on the use of such products as kefir, rice, buckwheat, apples. The negative factor of such diets is that it is psychologically difficult to have several days the same thing. The principle of a diet is a sharp decrease in the caloric content of a habitual diet, as well as a complete elimination of fats. The body begins to suffer from the lack of vitamins and trace elements, so the use of mono-diet can be justified as a cleaning of the body for 1-3 days.
Low-calorie and low-carb diets
The content of such diets is quite varied. During each meal, the serving should be small. Usually allowed to eat unsweetened coffee, green tea, cracker, grapefruit, orange, eggs, boiled meat, steamed fish and vegetables, fresh vegetables, unsweetened fruits and yogurt. It is necessary to exclude salted, fried and milk. Such diets are recommended to be carried out within 1-2 weeks, and their result will be a loss of 5-7 kilograms.
Negative impact of fast diets:
- The loss of excess weight is due primarily to the elimination of fluid, loss of muscle mass, but not fat.
- Lack of carbohydrates leads to poor health and slows mental work. Together with the liquid, potassium and calcium are washed out of the body.
- Lost pounds very quickly return, because the weakened body quickly makes up for lost time.
In order to minimize risks, it is necessary to use vitamins and mineral complexes, as well as not to reduce the number of calories less than 1000 calories per day, not to exceed the proposed period. And more, it is necessary to leave the diet correctly. Moderate physical activity is necessary. It is not necessary to immediately consume large amounts of carbohydrates and fats.
