the one you list looks like crap. I see very little in it that'll actually promote fat loss.
it'll make your wallet lighter though.
about the only fat burner I like right now is Thermocin by because its a revamped ECA stack. Synephrine takes the place of ephedra, Guarana for caffine, and White willow bark for the asprin.
its less expensive than the one you list as well.
physical activity doesn't really change, but Thermocin will raise your resting heart rate a little.
I see no reason to take fat burners at your present weight and bodyfat %, or age for that matter.
At least not until you've proven your diet and training are good. If those aren't already almost perfect, then any fat burner is just gonna waste your money and time.
