    I watched a show on BBC4 about how the diet of the nation had changed over the last 100 years and how our health had changed etc, and i do remember now how fatter people have higher metabolisms because of the amount of work they have to do.

    They also did a comparison between 2 sisters who were twins but had never met and were re united at 40 years old. One had eaten healthy and excercised her whole life watching her weight whereas the other had lived in the southwest of the US and eaten fatty meats and not watched what she ate her entire life and the weight diffrence between them was only 4 pounds.

    i think some of it has to do with genetics etc, and im not on about spot toning to the people who keep saying that, i know thats not possible im just asking a question as i dont eat that much but the fat never seems to disapear.

    If 2 people weighed 12 stone, with person A having 10% bodyfat and person B having 30% bodyfat, which person would have a higher metabolism? Also, someone said there's a difference between a higher and a more efficient metabolism. What does this mean?
    a higher metabolism is just that - your resting requirement for calories is higher

    fat people have more cells in general, so these cells need more energy

    now two people might have the same metabolism i.e. both burn same amount of kcals/day

    BUT someone with a more efficient metabolism tends to have better nutrient partitioning, what does that mean? more of the calories are burnt for processes such as movement than being stored

    they did a test about metabolism and got a bunch of people and asked them what they thought about their metabolism ie fast/slow/average and obviously people thought theirs was fast and slow etc and what they found out was that pretty much everyone's is pretty average. Most just use it as an excuse for their glutinous lazy ways.

    Horizon : A Diet Guide
    Thats the one! i only remembered it had diet in the title and t`was on BBC4. Quite an interesting program i thought to be honest, with the introduction of mass produced foods with more fat and preservatives in them weve seen a big increase in weight gain throughout society and this program documents it quite well.

    a very large person needs a lot more caloires to stay the same weight . because its more for them to move.

    I can introduce another factor to further complicate things:

    Skinnier can have a higher resting metabolism due to heat loss. They have a higher surface area to volume ratio than fat people, and as such, emit more heat per kilo of body mass. Since they give off more heat, their energy requirements can be a little higher, under a given set of conditions, than a larger person.

    What does this mean in real life terms?

    NOTHING FATTY! PUT THE CHIPS DOWN!

    NOTHING ANOREXIA BOY! EAT A ******* BURGER!!
