I didn't tried Lipovox, but I did tried a few diet pill and diet systems (Atkins) a couple years back. The problem with diet only method is that you tend to lose more water weight, and possible muscle mass, which you can easily gain the weight right back. This happened to me..
If you can, try to eat very CLEAN (meaning that no processed foods, no fast carbs - wheat, corn, whole what), no soda or diet soda (bad for liver, bad for fat burn).
Eat more vegetables, brown rice, quinoa, sweet potatos, lean meat.
Exercise - if you can try to do high intensity interval training because it'll really boost your metabolism and give you permanent results.
Good luck and god bless!
