One mental tricl I used to lose weight in the first place was to think "Ok, if i eat almost nothing today I will be able to get drunk so quickly and easily tonight." So I'd eat no breakfast, a small lunch, small dinner and then a bit of some High West, get pretty buzzed go to sleep and repeat. Another thing that really helped was my office was no where near any places to eat and they had no vending machines. So it was quite a hassle to get anything to eat during the day. Most of the weight loss was just due to sheer laziness.
