Each 100 milliliters of milk contains 54 calories, of which 3.4 grams of carbohydrates, 3.2 grams of fat, 3 grams of protein, no dietary fiber. So milk is a more nutritious food, and its three major nutrients are more abundant. If you drink a moderate amount of milk does not affect weight loss, but if you drink a lot of milk every day, and more than a certain amount, the carbohydrates and proteins can be converted into fat, directly in the body to hoard, which leads to weight gain.
