Fat storage refers to the process by which excess calories are converted into fat and stored in adipose tissue, primarily in the abdomen, hips, thighs, and buttocks. This is a natural function of the body that helps provide energy reserves for times when food intake may be limited or scarce. However, when an individual consumes more calories than they burn through physical activity or metabolism, those excess calories are converted into fat and stored in adipose tissue. Over time, this can lead to weight gain and obesity if not managed properly through a healthy diet and regular exercise.
