Personally, I was more surprised by the various groups of people who _don't_ have higher metabolic rates: > Children’s metabolic rates stay high until age 5, but the rate slowly begins to glide down until it plateaus around age 20. Interestingly, adult rates are stable until age 60, when they begin to decline. After age 90, humans use about 26% less energy daily, Pontzer says. > The study also found that pregnant wom…

This seems almost unbelievable to me. Almost everyone I know, with a handful of exceptions I can think of, had a dramatic change in what I can only say was metabolism at 30 declining steeply to 40. I can tell you personally my ability to lose weight when exercising daily has decreased significantly since 30. If it’s not metabolism, then what? Diet and exercise are almost identical.

You are probably consuming more calories than you think you are or not burning as many as you think you are.

I'll agree with that. There are certain lifestyle changes at that age range: office job, extra cash for eating out, etc.

I can't say for the cases you named but its easy to overlook small lifestyle changes, like how much someone walked in college vs after. That was one shift for me.

It's a combination of your lifestyle changing and your kidneys beginning to lose function. Your metabolic rate may be the same but your GFR is declining.

My 22 month old son wakes up at 5am, and doesn't stop running, climbing, singing and dancing, any possible "activity" you can think of until 7pm when we have to wrangle him for about an hour during "quiet time" until he eventually decides it's time him to sleep. The description "different species" seems apt because I really don't see how it's possible for such a tiny "human" to just have so much energy.

All in jest of course. My son is my world.
