Starvation

Simple. Don't eat. You're a fat ass, and your body can live off your excess fat, you flabby, fat fatty. For those with weak moral fiber, go into the wild for a few days with zero provisions. Lard ass! If you survive, I personally guarentee that being seen with your shirt off will be less of a concern.

Gandhi Your Family

This one is ideal for chubby practical jokers, attention whores or authentic zealous religous fanatics who would like to burn calories while they mess with their loved ones, satisfy their needy and unfufilling lives, or who are willing to risk death for some make believe fairy tale.

In this "diet", one takes into account the hunger strikes of Mohandas "Mahatma" Gandhi (which you have misspelled as "Ghandi"), eating and drinking nothing for three days while wearing a dhoti. Then, when all seems lost and you are about to die, drink some orange juice. Not only will you burn fat, you'll lose water weight, ensuring that your emaciated muscles look really cut to everyone else. Impressive!

Gandhi Extreme!

This is the former Ghandi (whoops), I mean "Gandhi" workout, except you spend an hour of each day doing pushups inside the sauna at 24 Hour Fitness. You Hardcore Indian man, you!
