Keep a lid on the munchies. Eat fruits and veggies if you are hungry. Don't skip meals. Don't eat junk.

Also, I take supplements:
green tea
5-HTP
DLPA
whole food multivitamin w/ herbs
coQ10
lecithin
relora
etc etc

CLA is also good (but I don't take it) and there are other SAFE, herbal diet supplements one can take. Just stay away from this big-name diet pills, they're complete crap for your health.

The most important things are, and always will be, diet and exercise.
