Discuss.

A new study challenges assumptions about energy expenditure by people, including the idea that metabolism slows at middle age. 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.
