I want to achieve a BMI within a healthy range, as I am slightly overweight. I'm not sure if I can stabilize that within 3 months, but right now I'm modifying my diet and bicycling as transportation whenever it's applicable, I'm starting to think that this may be inadequate.

I'm not sure if I'm doing it correctly though, and it's tough to find people to help when so many of them are just quacks and amateurs. You often get "nutritionists" when you're looking for dietitians.
