Low Carb Diet

A “low carb diet” is the common term applied to different diets restricting consumption of carbohydrates1. There are many variants of low carbohydrate diets. They all emphasize protein and fat (poultry, eggs, vegetables, fish, etc), and limit carbohydrates (starchy vegetables, grains, etc).

As a rule, such diets are used to lose excessive weight and to prevent or treat various conditions and chronic diseases, like obesity, high blood pressure, cardiovascular disease, metabolic syndrome, epilepsy2, polycystic ovarian syndrome3, etc.

How Does Low Carb Diet Work?

Carbohydrates are found in different products and beverages, like fruits, milk, vegetables, grains, nuts, legumes, seeds, etc. They are the principal fuel source for the body, as in the process of digestion, starches and sugars are decomposed into simple sugars. They are absorbed into the blood where they become glucose4. With the help of the insulin glucose penetrates into the body’s cells. Some part of glucose fuels the body’s activities, and its remains are transformed to fat.

Supporters of the low carb diet say that insulin forestalls breakdown of fat in the body because it lets sugar be used as a source of energy. Thus, if you decrease the consumption of carbohydrates, it will lower the level of insulin, which in turn will make your body burn fat and lose weight.
