That means he needs to create an average deficit of 1,167 calories per day to drop that kind of weight in six months. If he gets in 30mins of activity a day burning an extra 10 calories per minute (generously), he could eat 1,749 calories per day (actually a bit less since his TDEE drops as his weight does).

You can easily fluctuate 5lbs in a day with just water weight and food intake, so let's assume he was actually 290lbs at the start and 240lbs at the end. So 175,000 calories in 180 days is a 972 calorie deficit, which would put him at 1,950.

It's doable, if you're actually disciplined with what you're eating.

My guess is that he got lap band surgery or some shit. Good for him, who cares how he does it.
Lap bands pretty much aren't done anymore since they tend to break loose, slip around and try and tear your insides up but yeah.
