Alexander Voroshilov, doctor of the highest category, expert on nutrition and fasting: Kefir diet for fast weight loss. You can do it, but it is harmful if you feel hungry (and you will). Where there is hunger, there is an increase in acidity in the stomach. Next comes gastritis, then helicobacter pylori and ulcer. All in all, the diet is unfortunate.

Oksana Skitalinskaya, dietitian, vice-president of the Dietitian Association of Ukraine: The Japanese diet for fast weight loss is effective — it contains few calories, but they are healthy and not empty. However, breakfast is too poor — a cup of coffee is not a full breakfast — caffeine stimulates the brain, but does not give it energy in the form of nutrients, so the energy boost will be short-lived. If you supplement a cup of coffee with 1-2 tablespoons of low-fat cottage cheese, the result will be excellent. It is impossible to refuse from salt completely. Salt is needed in a small amount — 1 teaspoon without a hill per day. The Japanese diet may not suit people with reduced acidity of gastric juice, with low blood pressure. Given that the diet for fast weight loss is hypocaloric, it should be supplemented by taking multivitamins and physical activity.

Advantages: fast weight loss.
Disadvantages: potassium is excreted along with harmful substances and fat.
Natalia Samoilenko, dietitian, endocrinologist, chief physician of the «Capital» medical center: I have a very negative attitude towards diets for quick weight loss. They do not solve weight problems, but only aggravate them. Hard, low-calorie diets for quick weight loss with a deficit of nutrients give a quick result, but then the weight necessarily returns. Therefore they are categorically not suitable for the long term. The rice diet is good in terms of balance, but it is not recommended to «sit» for a long time on rice alone, especially for people who have problems with intestinal motility. For the rice diet it is advisable to take brown rice and boil it in four waters.
