Could it be that chronic calorie reduction has made your body adapt?
- hvs 5y agoI have no idea, but I doubt it. I ate the same way for years, but as I got older I started gaining weight, when I didn't before. The weight gain preceded the calorie reduction.

- makeitdouble 5y agoWithout special efforts metabolism decreases naturally with age (https://pubmed.ncbi.nlm.nih.gov/8361073/ https://pubmed.ncbi.nlm.nih.gov/8361073/) Even with special efforts, it’s only slowing/delaying the process, so progressively eating less is natural anyway.
- robbedpeter 5y agoMetabolism doesn't decrease with age. https://www.everydayhealth.com/diet-nutrition/metabolism-may-not-decline-with-age-as-previously-thought/ https://www.everydayhealth.com/diet-nutrition/metabolism-may... Body composition changes gradually over time. Going from healthy and fit at 20 to overweight and unfit at 40 can be reversed, it's not an inevitable decline. Eventually aging catches up, but it may not be until 60s or 70s when metabolism takes a noticeable hit. As with so much science, they got it wrong, but knowledge is getting better.
