Remember, the more you weigh, the more calories you burn during exercise. So if you weigh 115 pounds you will burn about 115 calories if you walk for 30 minutes at 3 miles per hour. Now if you weigh 300 pounds you will burn nearly 300 calories for the same exercise.. Guess that's good news for us fatties.

Are you serious? Why is this anyway? Why wouldn't you burn the same amount for the same amount of time and speed? Is it because it takes you more energy because there is more to get moving?

Just curious?

Putting this mathematically, eh?

But the hypothesis is incorrect. For one, a fattier person will not be able to do exercises with the same vigour, zest and speed as a trim/fit person. Hence calorie burning is not proportional to weight in a linear fashion.

Besides calories are burnt by muscle activity. The more muscle you have, the higher the calories burnt.

Can you put it this way, say if a slim and fit person exercises for an hour, and an overweight person exercises for half an hour, would they both lose the same amount of calories, seeing the theory that an overweight person would lose weight quicker and easily?

The overweight person will loose a lot of fat and water.

When it comes to calories, it is like this. First what are calories? Calories are measurement of body energy. Muscles burn calories. So a muscular person will burn more calories than a non-muscular person, even when not exercising.

But coming back to point, the fat person will burn more calories, because her/his fat will be converted to glucose and then to calories. But only if, the thin/slim/fit person and the fat/overweight person exercise with the same vigour and the same time.

Wow that is intersting. i knew that the heavier the person, the more they lost with doing the same exercises, but haven't really thought about how it worked. thanks.
