> people that have never actually been fat. "I did it and I lost 15 pounds

Also people who have never had an older metabolism. It's different. I was also skinny despite eating a ton and hardly exercising when I was 25. Everyone I know over about 30 can identify when their metabolism suddenly changed. Diet (and to a lesser extent exercise) advice from those who haven't hit their own wall yet is worthless for those who have. Those people need to stop over-generalizing their (limited) experience as universal truth.

A recent study found basically no change in metabolism from the age of 20-60: https://www.bbc.com/news/health-58186710

People usually just start packing on a few pounds a year (or more) in their 20s and it adds up.

I'm 40 and I can't pinpoint when my metabolism changed. I can pinpoint exactly when I moved in with my girlfriend, who cooks delicious food, instead of me ordering a salad a day as my main meal, but my metabolism itself seems to have hardly changed at all.
