Whether or not a person grows fat is mainly related to energy intake. If energy intake is greater than the amount of energy needed, the excess energy will be converted into energy storage substances and stored in the body, such as glycogen and fat.

When the excess energy is converted to fat, the person will become fat, that is, "long fat". If you drink milk before going to bed, causing an increase in energy intake, you will grow fat in the long run. However, if you drink it and exercise properly during the day, you won't be able to get fat.
