Fat memory period is a theoretical concept, which means that in the process of losing weight, the body reduces the size of fat cells, but the number does not decrease. It is said that once the weight is restored, fat cells will quickly return to their original size, leading to obesity again.

Although the existence of fat memory period needs further scientific research to confirm, in fact, the change of weight is closely related to the individual's metabolic rate and eating habits.

If you control your weight and reduce the size of fat cells through diet and exercise, but repeat unhealthy eating habits and lack of exercise for a period of time, you are likely to gain weight again and accumulate fat again in the original place.

Therefore, even if the fat memory period is an existing concept, we cannot simply think that once the fat memory period has passed, we will never gain weight again. Maintaining healthy eating habits, a balanced diet and moderate exercise are the key measures to maintain a healthy weight.
