How did you measure your body fat? What is your lower body workout? How would you describe your aerobic fitness?
I agree with alot of what has been said

- all calories are not created equal; Eating 3500 extra calories of refined sugar is different then 3500 calories that are low on the glycemic scale

- You will lose fat when you burn 3500 calories more then you consumed

- Protein is essential to build muscle; more muscle acclerates your metabolism and strengthens bones as well

- Endurance Aerobics, such as triatholon or Marathon training, requires a majority carb diet b/c exercise is over 1 hour and the HR is b/t 70-90% of MHR (fat can't be used as a fuel in this case); there are 280 million people in the US; the number that run sub 4 hr Marathons consistently would fit comfortably into the seating capacity at Wrigley Field and are thus the (very small) minority who can consume carbs

- Whether you have glycogen stores or not you will burn fat if your HR is b/t 50-70% of your MHR

- the goal should be the lowest possible BFP; 2-6% is essential fat for men however some can get down to 4%.
