Ripped musclesThe metabolism is every drop of chemistry needed to keep the body going. And the bigger the body - whether that is ripped muscles or too much belly fat - the more energy it will take to run.

The study, published in the journal Science, found four phases of metabolic life:birth to age one, when the metabolism shifts from being the same as the mother's to a lifetime high 50% above that of adults a gentle slowdown until the age of 20, with no spike during all the changes of pubertyno change at all between the ages of 20 and 60a permanent decline, with yearly falls that, by 90, leave metabolism 26% lower than in mid-life

"When people talk about metabolism, they think diet and exercise - but it is deeper than that, we are actually watching your body, your cells, at work," Prof Herman Pontzer, from Duke University, told BBC News."They are incredibly busy at one year old and when we see declines with age, we are seeing your cells stopping working."

Prof Tom Sanders, from King's College London, said: "Interestingly, they found very little differences in total energy expenditure between early adult life and middle age - a time when most adults in developed countries put on weight. "These findings would support the view that the obesity epidemic is fuelled by excess food energy intake and not a decline in energy expenditure."
