The fat content of ordinary pure milk is about 3%, and skim milk is about 1.5%. If you want to lose weight, I suggest you drink skim milk, which is also nutritious, like Mengniu in your picture! But if you are not overweight or have no urgent plan to lose weight, then you are with pure milk! Because skim milk is used to lose weight, don't skim if you want to gain muscle, because fat must also be added! In addition, the fat content of milk is basically ignored, and non-fat fat will not accumulate in the body. Also, be sure to mix pure milk, not sweet or sugary! Eating too much sugar is not good for fitness.
