I hate to sound stupid, but excerciseas much as you can, and watch how much sugar you eat... Drink diet instead of regular, dont sit around all day, take ur bike instead of ur car... There isn't any better diet method

Bike riding is excellent for losing weight quickly, you have to go miles, but no pain no gain, also yoga stretches for the face..

Good luck :)

Depends on what kind of biking you do... Road biking, yea you probably have to go miles, but cross country mountain biking you don't have to go as far becuase the type of terrain that ur on. Plus on a bike you can probably go 25 - 30 mph whihc makes the miles go by faster. Running is good too unless you get shin splints :( and swimming is an awesome way to get into shape especially if ur big and not areodynamic, it takes more work to move urself
