Does weight affect calorie burn?

Question: Does a heavier person burn more calories doing the same exercise a lighter person? What I mean is if I walked for 30 minutes with my other half would I burn more calories than him? He weighs about 138 pounds and I weigh about 100 more than that! If the answer is yes, does anybody know why?

Thanks,

Jade x

    Typically yes, however if you want an accurate calorie burn reading, use a heart rate monitor

    Yes, because the workload is greater. It takes more energy to move 250lbs 1/2 mile down the road than it does 150lbs down the same half mile.

    Yes. The reason why is it take more energy to move something heavier.

    Yes - it's basic physics. The energy expended is equal to the amount of work done. Work done = force (needed to move a mass/weight) x the distance. Since you weigh more than your other half, your work done (for the same distance) is greater than his. There are a few more variables, but those are largely negligible for this particular case.

    Yes.

    However, a lighter person, on average, is in better shape, and would likely achieve a higher calorie burn than a heavier person, because a person in better shape is able to exercise with greater intensity.

    Which is why professional cyclists have that lean build for all the reasons previous posters described. People with a lean build have an advantage over stocky guys on those hills.
