Have you all checked the NYTimes article that came out last week about metabolism?:
It is a really interesting read, and it made me rethink what I thought I knew about metabolism. I always believed that it slows when you are older and differs between men and women, but the study done shows different results. What did you grow up knowing about metabolism? I also heard of people speeding up their metabolism, but I didn't know that was a thing until recently. Looping in @Tiffany_L as well, hopefully you can give some good insight!
Interesting article! I tried to access the actual study but it requires a payment. The numbers here are interesting and my mind points to understanding how stress impacts weight gain/weight loss and metabolism. Stress is seemingly difficult to measure. Then there is genetics! But overall, it is hopeful to know that 20-60 years old our metabolism generally maintains.
