Becoming overweight as a child can make weight loss a more significant struggle throughout  life. Scientists identified adolescence as a critical period for the development of obesity.
A person who becomes overweight during adolescence is much more likely to struggle with obesity later in life. An overweight adolescent has a greater chance of being obese as an adult than an overweight child who has not  reached adolescence.
The reason for this is that weight gain in adolescence increases the amount  and size of fat cells. Once fat cells are created, they cannot be lost through weight loss. When an adolescent tries to lose weight, he or she can only limit the size of the fat cells and not the total number of fat cells. The only way to get rid of fat cells permanently is through liposuction, a surgical procedure in which the fat cells are removed from the body. Liposuction is not a realistic option  for most people, so the best way to control adult obesity is to limit the proliferation of new fat cells developed from childhood obesity.
