I listen to podcasts when I walk outside. On a recent walk the speaker was talking about the myth of it being harder to lose weight as you age. She claimed it is self fulfilling. We believe it is harder so it becomes harder. Her argument was basically if it were true why are there so many very thin elderly who struggle with illness because they have so little reserve. I was still struggling to believe her but I continued listening. The argument made is that our metabolism changes (slows). Not so, she says. If we maintain the same level of activity our metabolism would not be slower but as we age we sit at our desks working, do sedentary activities etc etc. So our metabolism does slow due to lack of activity. We however continue to eat the same amount as when we were chasing little kids, generally being more active etc. Which leads us to gain weight. So in the end we need to exercise/be active more and eat based on our actual needs not what we are in the habit of eating. I found the whole thing interesting and it makes common sense to me. So I am going to stop using my age as an excuse. MFP and track my portion sizes much more carefully. What do you think?
