    So I've heard conflicting theory's but wanted to know if anyone knows how long it takes for a body to start burning fat after a cardio workout. I've heard some say instantly, or that it takes 20 minutes of running for it to start, and then I've heard some say cardio should only be done in the morning before any meals. Also, I've been working out and then eating my dinner or lunch right after. Is that recommended? Thanks icon_smile.gif

    You can't listen to what people tell you. Your body will begin utilizing fat as fuel around 2 minutes into a run according to the diagram at a Road Runners Club of America certification course I took last Summer. The class is sanctioned by the American College of Sports Medicine so I assume they know their stuff.

    I think it's good to have some sort of fuel in your system so you get the most out of your workout. If you haven't eaten in 10 hours your body is in starvation mode, and if you go out and do intense exercise, it's not going to work out to well for you. Some people like to exercise on an empty stomach, but I typically will eat at least a banana and wait about 15 minutes before I being running if I'm running in the morning.

    You should be getting something into your system after a workout. Make sure you're making intelligent decisions for your post workout meal. Your body has a window of opportunity to take in carbohydrates and protein to replenish the muscle fibers you've broken down through exercise. I've heard something like an hour and a half.

    The problem with what you're being told is that the school of thought seems to be that everything you put into your body automatically plummets to your waist line. That's not true...food=fuel. It's when people use exercise as a justification for eating whatever they want that gets them in trouble.
