I'm commenting here because this is the greatest thread title in history. I cracked up.
That being said, the definition of insanity is doing the same thing over and over again. Clearly, "carb control" is not working. I'm guessing he has an excruciatingly high intake of dietary fat, leading to a massive calorie surplus. Remember - fat is most easily stored as fat.
1.) Cut fat intake substantially and up protein substantially. Protein is more filling than fat, has less than half the calories and is the least difficult to be stored as fat. Raising protein and cutting fat should lead to spontaneous calorie reduction without impacting satiety too much.
2.) Start lifting. Often. Look into "Starting Strength" and get into a solid routine 3 days a week. I'm a fan of Monday/Wednesday/Friday lifting with some light cardio on Tuesday/Thursday and weekends "off" but with lots of "play."
That alone should help quite a bit. If he can keep carbs low while dropping fats and adding lifting, that should do a lot. If he is low on energy (and it sounds like he has enough body fat to maintain a healthy deficit well), I prefer carbs to fats because they aren't stored as fat as easily. ACME has eye round for $2.99/lb this week - I just picked up a whole one. I prefer lean red meats for fat loss.
