He is obese because he eats too much and does not exercise
But he also could well be suffering from PRADER WILLI SYNDROME
It is a rare genetic disorder resulting in PHYSICAL MENTAL and BEHAVIORAL problems. A key feature is an insatiable appetite...always feeling HUNGRY. For food sex power domination. INSATIABLE.
We don't know if he does or doesn't have it. But we can tell just by looking at him and listening to him and evaluating what he has done and said and threatened to do
that something is very wrong with him..
PAY ATTENTION.
