Are commonly held beliefs regarding metabolism correct?

It’s widely believed that people put on weight in middle age because their metabolism slows down and that women have slower metabolisms than men. A large 2021 study (6,500 people) indicates that those assumptions are wrong.

What are the results?

Rather than metabolism slowing in middle age, there are four distinct phases of metabolic change: 1) infancy until age 1 (3% growth), 2) age 1-20 (metabolism slows about 3% a year), age 20-60 (it holds steady), and after 60 (metabolic rates decline 0.7% a year). So, for adults, metabolism slowdown doesn’t happen until after 60 and there are no real differences in metabolic rates for men and women. These findings have big implications for medicine and wellness.
