I looked for some info before "weighing in" on this subject ;(

The average guy 6foot 200lbs needs about 2700 calories to maintain his weight, at 400lbs he would need 3900 to maintain his weight and 3200 calories to loose weight. If he wants to maintain his unhealthy "lifestyle" he should have thought about that before killing someone. I think it would be reasonable that his diet be bumped up to the 3200 calorie limit if thats what a doctor would recommend but nothing more.
