I have heard from several sources that there is a "fat-burning" zone that is something like 60-70% of your maximum heart rate. This, to me, means that 500 calories of work at 65% maximum heart rate will be more effective at burning fat than 500 calories of work at 85% of maximum heart rate. But isn't weight loss achieved by a calorie deficit, meaning that workout intensity is irrelevant?
I have been working out at about 85% max heart rate, but I definitely wouldn't mind working at a lower intensity if it is more effective. But, if there is no difference, my thinking is, why bother working out longer at a lower intensity if it makes no difference?
Can anyone help me on this?
