ScienceDaily (June 19, 2008) — Exercise does not suppress appetite in obese women, as it does in lean women, according to a new study.
"This [lack of appetite suppression] may promote greater food intake after exercise in obese women," said Katarina Borer, PhD, a University of Michigan researcher and lead author of the study. "This information will help therapists and physicians understand the limitations of exercise in appetite control for weight loss in obese people."
Borer and her co-workers sought to better understand how changes in body fat level influence appetite and a hormone called leptin,

To quote Nelson Muntz: “Hah hah!”
I’m lean and have no difficulty staying that way, but one thing I’ve noticed: after a heavy meal, I’m hungry again in a few hours, whereas if I don’t eat much, I don’t get hungry. Eating too much increases hunger.
Guess that's why I'm not fat.

I am not allowed to post anything on “fat” threads. I get myself into too much trouble....
It is called self-discipline.
Also excercise regularly.
I stay thin this way. The wife loves it. :>)))))
thanks, bfl
That's the kind of thing my anorexic relative says.
Most people who are overweight are insulin resistant (IR). Researchers still aren’t sure if the IR causes a person to gain weight or gaining weight causes IR. I am IR. I cannot go long periods without eating or I have hypoglycemic attacks. My vision blurs, I get sluggish, sleepy, and shaky. For that reason, if I am outside of a controlled environment where I can’t get to food immediately when I have a hypo attack, I eat regularly even if I am not hungry. I try to avoid refined carbs and balance carbs with protein every meal, so my blood glucose won’t spike and then come tumbling down in an hour or two. I am not diabetic, but I have family members who are type II. IR is often a predictor of type II.
Exercising makes me hungrier and makes me more prone to hypo attacks. I do exercise. It is important for my cardiovascular health given my family history, but I feel like I am in a vicious cycle that makes it impossible to lose weight.
I’ve tried various meal plans that include more protein or balanced protein & carbs, but none seem to make much difference. I can’t eat carbs-only for any meal.
Once again, we don't know what we don't know.
FReepmail me if you want on or off the diabetes list.
Hmmm. I’m reasonably lean but when I exercise, I get HUNGRY.
I don’t believe hunger is the reason fat people overeat. It’s through boredom, depression, stress, habit, etc.
You're partially right about that. I gain weight when I get sick. I crave massive salt and I think the act of swallowing soothes my sore throat.
I fight with my weight all the time. My best friend stays lean no matter what. Here are a few things we've figured out:
When I get stressed, I get hungry. She looses her appetite.
When I get depressed, I eat. She can't eat.
When I get nauseated, I start to graze, looking for something to calm my stomach. She can't eat.
When it's time for a meal and I'm truly hungry, it takes about 30 minutes for me to *feel* satiated, no matter how much I eat. (If I eat a sensible meal, I have to wait before I stop feeling hungry.) She feels satiated in 5-10 minutes. (If she's really hungry, she lets herself go and eats a wonderful meal without thought, but her body tells her to stop very quickly.)
She has a very high "off" volume. Her body tells her NOT to eat very loudly and she can't over-ride that. My OFF volume is there, but it's very quiet. More like a suggestion.
When she's full from a meal she isn't tempted by food. If I'm very full and I see or smell something tempting (desert) I'll start to salivate and have to stop myself from eating more.
We both have hypoglycemia. It takes her about 5 minutes to get her BG up. It takes me 20-25.
There are very real differences in how our bodies react to food, illness, emotions and exercise. I keep from turning into a cow with a LOT of self-control and effort. She really doesn't think about it at all. I'm never going to say that I eat less than she does - I know it's not true. But I most assuredly *feel* like I do.
I could have told you that.
Meow!
I've got a buddy who varies between 330 and 360 pounds. He's always eaten less in a day than I do, even when I was 165 pounds. I had the fortune to have an excellent metabolism that made me fidget enough to burn excess calories if I wasn't getting enough exercise. For about 6 years nothing I did could get me to vary more than 1 pound from 165 pounds. Then I got type one diabetes, and I started gaining about 10 pounds a year unless I exercised at least an hour and a half a day four days a week.
While virtue and gluttony plays some role in some cases of obesity or the lack thereof, don't take for granted the excellent biofeedback mechanisms that you are lucky enough to have keeping you thin. If those mechanisms break you'll understand exactly how hard a struggle it is to maintain a low weight, and why only those with steely resolve manage to do it over a long term.
