Dieters need to control calories. Whole milk has higher fat content and calories than low-fat or skim milk. Because full-fat milk retains the original fat, low-fat or skim milk reduces or removes the fat content in milk, and the natural calories are also low when the fat content is low. Compared with whole milk, low-fat or skim milk is not rich in taste, but other nutrients still exist, such as protein, which is rich in content and can supplement nutrition for dieters.
Although drinking low-fat or skim milk can reduce fat intake, thus reducing energy intake, it is not easy to gain weight, but drinking these milk has no effect on losing weight. People who lose weight should not drink skim milk as water to avoid indigestion and bloating caused by drinking too much.
