How long did it take you to gain that 40 pounds? And now you say you want to lose it fast? You have to kill yourself to lose 2 pounds of fat a week consistantly(especially when your under 10%), and if your 40 pounds overweight you probably don't have a great deal of dietary discipline. I'm not trying to be mean, but according to my calculations you want to get down to 4% bodyfat in just 2-3 months. Ask the guys on the boards here how many have ever managed to achieve this, and how long it took them. My advice, try for 1 pound a week and look great by the end of the summer. Just my two cents
