‘I
want to know if burning 500 calories more than I consumed will make me lose weight.” The first thing to know here, really, is that unless you are in a lab with electrodes fitted all over your body, it is almost impossible to calculate how many calories you have burnt or consumed. So all that you can get in the best scenario is a rough estimate. So rough that the error is generally plus or minus 500 calories. So much for your great weight loss equation.
