Fat Cells

There are distinct biologically-based reasons for why we get fat. One of the biggest culprits is, aptly named, fat cells.

 The term for these fat cells is adipose tissue and it is located underneath the skin. Men tend to carry body fat in their chest, abdomen, and buttocks, while women generally store fat in their hips, waist, breasts, and buttocks. Any carbohydrates or proteins consumed that are in excess will not be burned and converted into energy but will be stored as fat.

 They will travel through the stomach and intestines and be converted into glycogen and triglycerides in the liver. The triglycerides are transported in the blood from the liver and deposited as adipose tissue cells beneath the skin and around the intestines.Fat cells grow in number, a process called hyperplasia wherein more fat cells are created, typically during childhood and adolescence, pregnancy, or periods of quick weight gain. Not only do fat cells multiply and store more fat but they also grow in size, a process called hypertrophy. This occurs as we gain weight with age. Once fat cells are formed, they cannot be eliminated. They can reduce in size, however.

 When we diet, our systems tap into our fat storage, burning fat in the cells, and converting it into energy. Some controversy exists over whether we achieve a finite number of cells by the time we reach puberty or whether they continue to multiply into adulthood. Most research suggests that the former is true and this offers an explanation for why overweight children struggle to lose weight as adults more than their thinner counterparts.

 The theory is that the greater number of fat cells that are now stationary cannot be eliminated and can only decrease in size through greater effort. Another theory suggests that people who have larger numbers of fat cells will consume more food. Some health experts believe that the size of the fat cell is directly related to the hunger mechanism.

 The smaller the fat cell, the less appetite the individual has. Whether or not a propensity for weight gain is built into our genetics, a proper diet, exercise, and knowing the secrets to a natural weight loss still apply.
