# Why do I burn more calories exercising if I weigh more?

## It takes more effort to exercise if you weigh more.

The more you weigh, the more effort it takes you to perform a particular exercise. Therefore, the more calories you will burn.

##### Example:
• Someone who weighs 200 lbs will burn approximately 160 calories walking for 30 minutes (at a 20-minute mile pace).
• Someone who weighs 250 lbs will burn approximately 195 calories walking for 30 minutes at the same pace.

The person who weighs 250 lbs will have to work harder to walk a 20-minute mile than someone who weighs 200 lbs.

Think about walking while carrying 25 lb weights at your sides (50 extra pounds). It would be extremely hard! That’s what it would feel like to be 50 lbs heavier and walk at the same pace.

It’s also important to note that it may not be realistic for someone who weighs 250 lbs to exercise at the same intensity (pace) as someone who weighs 200 lbs.
