You need to emphazise on cardio, i.e. run, jog, walk, whatever for 25-40 minutes per session to really burn fat off your body, at least until you are leaner and your metabolism has adapted to burning fat quicker. Studies have shown that you need at least 2000mg of L-carnitine per day in order to get any real benefit on fat/wt. loss. Studies show you need at least 6000mg pyruvate per day for wt. loss benefit. Try 200-600mcg chromium polynicotinate supplementally. I don't recommend ephedra-based fat burners, but if you take them, please take when YOUR NOT WORKING OUT. It is more effective that way. For a fat burner to take just prior to working out, take pure guarana or kola nut powder to equivelant of 100-200mg caffeine. That will help mobilize fat while working out quicker and is much safer than ephedra. Take cold showers to reestablish your BAT thermogenic capacity. Works for me. Hope helps.
