The best way to increase your metabolism is eat right and gain more muscle. More muscle burns more energy.
My bad, you're right. I was half paying attention and half watching something on youtube while I typed that. You're right, you want to shoot toward a stable insulin level throughout the day. That's also the rationale behind eating smaller meals throughout the day as opposed to fewer, larger meals.
Chromium picolinate is supposed to help keep your insulin levels steady throughout the day. It's a pretty common supplement, you can find at most health-food stores. Someone else will probably know more about it than I do.
