Does Our Metabolism Slow Down With Age?

Have you ever wondered if after you turn 25 or 35 or 45, or whatever age you think is "over the hill" for your metabolism, if it really slows down?

It's a question I get a lot, so I researched it this past weekend and came up with an answer that might surprise you.

Check out the article I wrote for my partners at Prograde Nutrition here:

Am I doomed to get fat when I get older?

I came upon your site through Krista's ages ago and have found it so informative. I read this article with interest. There is one question for which I can't seem to find an answer anywhere in the "fitness world". When calculating calorie expenditure why does no one ever seem to count mental activity? Are there no studies on how many calories are burned when you think "a lot"? This is a serious question, because it is obvious empirically that you do feel quite drained after a long bout of mental "exertion". Unfortunately, this expenditure does not contribute to muscle building, but the energy is still spent. Do you know of any studies that have addressed this issue?

Agnija - thanks for your comments! For your q, I'm not 100% sure, but I totally know what you mean... I'm ravenous when I study or doing something mentally taxing. I'll look into it and write about it. Thank you!!

Great website, but I was a little disappointed in reading your article "Does Our Metabolism Really Slow Down As We Age?". It sounded so much like everything being touted currently, no scientific info.

As a Phd, you must have great insight to lipolysis and neuroendocrine system in how these relate to aging and hormonal changes. While it is true that many americans become more sedentary as they grow older, there must be some science out there that addresses metabolic slowing and steps to take to lessen it.

Gia - you're right, and in what I've learned and experience with the clients I work with, metabolic slow down with age is more to do with hormonal shifts and oxidative stress than other things. But, being sedentary is a too common theme. Especially in America...
