Moreover, the nutrition of skim milk powder is not as comprehensive as that of whole milk powder, and there are almost no fat-soluble vitamins A, D, E and carotenoids. Besides, dieters should really drink whole milk, because they will feel full and be more "anti-hungry" than skim milk. The most important thing is that whole milk tastes better! Silky and mellow, it smells sweet, which is impossible for skim milk.
The fat of skim milk is more than 2 times lower than that of whole milk, so it has less calories and is not easy to get fat. But I think skim milk tastes bad, so it's hard to stick to it. You can mix some whole milk and skim milk.
But it is best not to drink milk on an empty stomach for breakfast, which will affect the absorption of protein.
