Im currently taking xenadrine and restricting my carbs to 10-20gs per day. What are some essential guidelines i shuold follow in order to try to lose fat. Im 5'10, 180lbs, and i dont know what my bf% is. I find that I tend to gain muscle pretty easily with only a little bit of weight lifting. I have tried lower weight and more reps but either way I keep gaining muscle. Right now i jus wanna concentrate on getting more defined and cut before i try to bulk up. thanks
