signals that tell us we're full: the path to obesity
that was a hard title to pick!!
there was a thread yesterday on spotlighthealth.com that was intriguing, so i'm borrowing it for here. one preop had asked her surgeon how she had gotten so heavy, expecting the usual answer about how it was all her fault. but he said something along these lines, according to the post:
normally, it takes about 20 minutes for the 'we're full' signals to get to the brain so that we should stop eating. but apparently years of yo-yo dieting and calorie restriction truly disrupt this mechanism, and it often takes 30-40 minutes for the signals to show up, leaving us more time for more calories. plus dessert.
an interesting idea. i wonder if making sure that we eat for only 20 minutes could help people lose weight.
one thing i DO know is that we are told to take 20-30 minutes to eat our meals, and if we're not done by then, we have to stop eating anyway. we were told that this is because eating longer sets us up for too many calories and a grazing pattern, besides stretching the pouch.
but maybe this feedback loop is an issue as well..
anyone have a clue??? opinion????
