Everyone knows conventional wisdom about metabolism: People put pounds on year after year from their 20s onward because their metabolisms slow down, especially around middle age. Women have slower metabolisms than men. That’s why they have a harder time controlling their weight. Menopause only makes things worse, slowing women’s metabolisms even more.
All wrong, according to a paper published Thursday in Science.....
Central to their findings was that metabolism differs for all people across four distinct stages of life.
There’s infancy, up until age 1, when calorie burning is at its peak, accelerating until it is 50 percent above the adult rate.
Then, from age 1 to about age 20, metabolism gradually slows by about 3 percent a year.
From age 20 to 60, it holds steady.
And, after age 60, it declines by about 0.7 percent a year.
