Do you believe in the Atkin's diet: eat no carbs?
My gut tells me this is silly, but it seems to work. I still believe in eating less than you burn to lose weight. Oh, and exercise at least 4-5 times per week, 30+ minutes per session and go aerobic.
Cam, if you ride your bike a lot, you'll need protein shakes or lots of extra food to keep your muscle mass. You might find that keeping weight on is as hard or harder than losing weight.
