Regarding fat burners/stackers/metabolism enhancers. On this site, go to Main Low-Carb Diets Forums & Support, and go to the General Exercise (Under Exercise) forum. There is a "sticky" at the top with lots of names of "stackers". TrainerDan has all the infor anyone could possibly need. Including cautions, etc. Read this before you buy any - he tells you the best kind, or take any (lots of do's and don'ts).

Good luck,
Anna
