how would anybody no if there metabolism is fast??

If you can eat anything you want and generally don't gain any weight it's probably because of a fast metabolism. If your metabolism is slow (or even just normal) it burns energy (calories, carbs, etc.) slower and if you were to just go around eating like crap you'd gain.

gah...wish that was me!! :laugh: lol

There really isnt any way to know whaat it is like. Although there may be some Scientific ways of testing it I dont think they are available to the general public. I asked my Dr if there was a way to test mine and he didnt know of any.

you can only get an estimate and that is by keeping track of the calories you eat over a period of time and then seeing if you gained or lost during that time.

This is why any Calculations for BMR should only be used as a guide. some peoples willbe much higher and others will be much lower.

The Funny thing about it is for general health having a slow metabolism it considered to be healthier, but for weigh loss it sucks!

Usually we consider that when things are more efficient that they are better! but the metabolism is something that most of us consider bad if it is more efficient.....Bad for weight loss anyways

believe it or not there are people out there who try to gain like 5 or 10 pounds cause they think they are too skinny and can't do it

There's a tall skinny girl in my aerobics class who eats chips and cookies before and after class. =\
