American nutrition experts found that people who have more than 3-4 servings of dairy products in their daily diet are only one-sixth as likely to get fat as those who don't eat dairy products. Clinical studies have also confirmed that drinking about 200 grams of milk every day can reduce weight and waist circumference under the premise of constant calorie intake. Milk is easily absorbed by human body, and contains advanced fat, protein, minerals and vitamins, which can whiten and moisturize skin and eliminate wrinkles. Recent studies have also found the principle of milk weight loss: the rich calcium in milk can effectively degrade human fat, reduce fat deposition and maintain normal weight. Experts from the Nutrition College of the University of Tennessee found that when the calcium content in the human body is low, a hormone called "Calcitriol" will be secreted, which can promote the production and storage of fat. Calcium can inhibit the production of this hormone, thus reducing fat production and accelerating the rate of burning fat. The effect of calcium intake through milk is twice as high as that through other ways; At the same time, milk contains amino acids that promote muscle growth. Therefore, if you eat more dairy products, you can lose more fat instead of muscle. Experts remind that adults should consume 1000 to 1200 mg of calcium every day, and the body can absorb only about 500 mg of calcium at a time, so it is best not to eat the whole day at one breath, but to divide it into three times. The American food guide recommends drinking milk three times a day and drinking a glass of milk with cereal for breakfast, which is beneficial to the absorption of protein and calcium and to mobilize human functions; Have milk when eating snacks in the afternoon to promote intestinal peristalsis and clean up the intestines; 200 ml of low-fat milk in the evening calms the nerves and draws a perfect full stop for the "slimming project" all day.
