I think it's worth it. I now know how many calories I can eat without gaining weight. My doc says eating red spicy peppers can speed up metabolism, but I don't like spicy foods. Maybe you do, though.

She tried Metformin to help get my metabolism going, but it had bad side effects on me such as diarrhea.

Also, more exercise/activity can help.

And caffeine such as in green tea--and a moderate amount of caffeine such as in coffee and other things in general, if your doctor okays it.
