Exercise affects Satiety

Posted by tinako on March 15, 2013

This connection took me completely by surprise.  I have been asking friends and family how they experience satiety, the sense that you’ve had enough to eat, and found there was a wide variation.  One friend says she has never felt satiety, that she always wants more.  A family member tells me that to him satiety is on or off, and that it doesn’t kick in for a while after eating.  My son and I, on the other hand, feel it slowly coming on as we eat – we feel a stretching sensation in our stomachs and know from experience at what point we need to stop or we will feel ill later.  Is the knowing satiety, or is it the ability to stop eating?  There was a time (before I ran) when I would eat myself sick and continue to eat – did I experience satiety or just a stomachache?

I also figured satiety was something people were ignoring, or the call for food was overpowering will. My friends and family are often surprised that food just doesn’t have much of a hold on me.  For this reason I’m rather humble about my ability to maintain my weight – somehow my wiring has made it easy.

A recent article in the New York Times has astonished me.  In The Appetite Workout, two studies are cited opening a window onto a new view of satiety, and it’s all about exercise-induced hormones.  The article is short and well-written, so I won’t summarize it.

But they weren’t measuring people’s sense of how full they were.  They were measuring how much they ate.  In this case, at least, satiety is not the awareness but the action.

By the way, I run, but my son doesn’t, and we’re both normal weight, but at 13 he still has less control over what he eats than I do, since I shop and he is penniless.

    This definitely makes sense to me. When I run, I am not hungry afterwords but when I replenish I have a much greater awareness of what is going into my body and how my body will react. I never eat until I am completely full because I know how it will affect me later.
