Loosing Body Fat

Q: I am trying to lose body fat and am walking and running 4-5days a week on a treadmill. When I walk, I go 40 minutes at a pace of 4.3 mph (pretty fast). When I run, I go oh, 20-some minutes at a pace of 5.6 mph (jogging for me). Which would be better for losing body fat? I know the longer and slower the better.

A:  Fat is a low grade fuel. If you are pushing too hard during your workout (anaerobic exercise) then the body can't break down the fat fast enough to utilize it as fuel. Your body will by-pass the fat and use the glucose that is stored. You would be better off going slower for a longer period of time.
Good luck!
