Where's the Fat?
Fat, or adipose tissue, is found in several places in your body. Generally, fat is found underneath your skin (subcutaneous fat). There's also some on top of each of your kidneys. Other locations depend upon whether you are a man or woman:
An adult man tends to carry body fat in his chest, abdomen and buttocks, producing an "apple" shape.
An adult woman tends to carry fat in her breasts, hips, waist and buttocks, creating a "pear" shape.
One amazing fact is that fat cells do not multiply after puberty -- as your body stores more fat, the number of fat cells remains the same. Each fat cell simply gets bigger!
In addition to fat tissue, some fat is stored in the liver, and an even smaller amount in muscle...
Your weight is determined by the rate at which you store energy from the food that you eat, and the rate at which you use that energy.

I think "apple"/Pear shape or central obesity is common in case of DT2/IR. How puberty is related to diabetes on view of above quote?
