I have read a few research articles that indicate that many overweight individuals feel that they eat a "normal" amount of food when in fact they are eating quite a bit more than a normal person. I would imagine that similarly, a skinny persorn might feel that they eat "alot" of food when in fact they may eat just a normal amount.

So my question is, given that your body is simply a relatively complex bio-chemical system, is there any credence to the notion of a "fast" or "slow" metabolism. That is, does everyone really burn x amount of calories per kg of muscle/fat/etc. with y amount of exertion and it is merely our perception of our activity/intake that gives rise to the notion of a "fast" or "slow" metabolism. Or is there actually some chemical differences in the body that makes the metabolism of one individual different from the next?

I am interested to here other people's opinion on this...
