In my gym, the cardio machines have different heart rate recommendations for fat-burning and cardio. For me, male 51, 178 lbs that amounts to working at about 110 for fat burning and 136 for cardio. So, if I burn a 1000 calories at 136bpm, will I burn less fat than 1000 calories at 110 bpm. Sorry if this has been covered, but can anybody with an informed view enlighten me..?

Best regards, David :huh:

    You can pretty much ignore any of that "fat-burning zone" stuff.

    Work out at a rate that allows you to complete your workout.

    The two principal sources of fuel for any exercise are glycogen and fat.

    At very low intensity you burn a higher proportion of calories from fat than glycogen but burn far fewer calories for a given period of time. At higher intensities you not only burn far more calories (the key to fat loss) but you enjoy improved cardiovascular health.

    Simply put, the so-called "fat burning zone" has absolutely nothing to do with weight loss, it's only of interest (in a meaningful way) to endurance athletes who train to burn fat as even the skinniest marathon runner has, for all practical purposes, a virtually unlimited fuel supply.
