Get your wisdom teeth extracted - I looked like a well beaten up gerbil for a week, and in that time lost a stone with no effort at all.
I think it is essential to ensure you have all 4 removed at the same time, under general anaesthetic on an overnight in hospital where they have used hammer & chisel to get one out which has fused to the jaw-bone.....this will def ensure the correct amount of bruising and pain to prevent effective eating for a week.
cheers
