Human bodies expand for storage. They expand for MUSCLE or POISONS. Storing poisons is a self-protection measure, to keep the body from premature death.

Poison storage or swelling = Fat / Obesity Storing MUSCLE = Strength / Athlete.

That is why the obese don't all die once they top a certain weight.

Life quality is determined by: —Habits—Diet—Exercise—Awareness—Working with others—Focus on rewarding purpose. Less = DEATH

Stay active, stay lean, stay focused on a purpose greater than you.
