I have been lowering my b.f. % for 4 months. I dropped from about 22% to 15% but now I am having a bitch of a time getting below 15%. I weight train 5 days a week on a 3 day split. I used to do more cardio. I will try to do cardio at least 5 times too. So many factors, so difficult. Diet, training, cardio, high days, low days? Carb up, carb down? damn, I don't know. I need to be taught by an expert.

(i tried hydroxycut hardcore - couldnt sleep, i am taking ephedra now (i dont know if it is even real, and i just bought a new fat burner called Final Burn. Also, BCAA 10g/day, glutamine/15g/day, creatine 5g/day during training, whey isolate 40g/day, oatmeal, avocado, uncooked nuts, chicken, salmon, broccoli, corn, cottage cheese...
do i need to have a high carb day once a week? i am now 6'1", 195 lbs, 15%bf, 28 yrs old.
