Drinking milk generally doesn't make people fat. The calcium component added in milk is mainly to supplement calcium trace elements in human body and promote bone health; The fat content in whole milk is generally around 3%-4%, and the fat content in low-fat or skim milk is even lower (0.5%- 1.5%). Milk is not a high-calorie drink, so whether it is full-fat, low-fat or skim milk, it will not get fat because of the fat in it. Low-fat milk saves less fat than whole milk, so cooking with a little more oil will make it all up.
But people with certain basic diseases, such as hypertension, hyperlipidemia, diabetes or obesity, should pay attention to the fat content when drinking milk.
