This doesn't seem to line up anecdotally;
The first outlier I see is female health and PCOS, starting in mid 20s for women.
The next outlier I see is insulin resistance and pre and diabetes based metabolism decline.
From a hormone perspective, nose, ear, chin (femalr), and head hair seem to be going under significant change.
Mid 20s with when your lifestyle shift just starts to catch up to you.
You go from a more active young person that eats just enough to get back to hanging with friends to binge drinking in an instant. Then you go from that to a much lazier, snackier lifestyle of 9-5.
Yeah, people on the whole do get fatter in their 30s, but that’s very easily linkable to lifestyle.
This is caused from eating too much, not a decline in “metabolism”
So, the combination of the research and my anecdotes - and your response seems to be
That by our early 20s our metabolism has already slowed (sugary food, alcohol, precipitous drop in activity)
No, our metabolism isn't "slow" (for 99% of people). People just start eating much more and moving much less.
Insulin resistance and PCOS absolutely have effects on metabolism. It’s very well studied.
how many outliers or exceptions do you need before you can throw out the theory
