I'm glad you posted this, Carla... I always like knowing the science behind things... I've read many times in this forum that the only reason to not exercise is because it will make you hungrier... it never affected me that way (& I've been exercising from the very beginning), so I always wondered... what you wrote, & what Elizabeth has posted before, makes tons more sense to me... I'm not doubting that some people's experiences have been that they were hungrier when they exercised, but maybe they were really, as Dr. Tran Tien says in his book, thirsty instead... we often mistake hunger for thirst, & that's probably one reason this diet & many others emphasize drinking lots of water...
Here's the quote from the doctor's book (p. 105):
What if I’m hungry after a workout?
You’re probably more thirsty than hungry. It’s normal to drink lots
of fluids after exercising, because your body has lost a great deal of
water. The secret is to avoid overly sweet beverages and to go for
those that are just sweet enough to provide energy. Salty drinks are
better, because they replenish the salts your body has lost through
perspiration.
He continues with this:
As for appetite, you’d better rethink your preconceived notions.
Experiments on rats revealed that an active rat that became inactive
sought solace by gobbling down food and getting fat, perhaps out of
inactivity or to compensate for it. It turns out that the same is true
for people. A sedentary lifestyle increases food intake more than
regular physical activity does. When you’re active, you eat fewer
calories and the calories you do eat are burned faster and better.
There’s an added benefit: regular exercise tends to delay weight
gain, as shown by an experiment conducted in 1995. Two groups
of obese women were put on a diet, but only one group exercised.
The women who exercised had an easier time sticking to their diet
and once their diet ended, 90% of them maintained their new
weight, compared to just 34% of the women in the group that did
not exercise. An excellent example, don’t you think?
Which leads me to this article I found on
SportsGeezer.com:
Exercise Makes You Want to Eat Less
Hungry again? Perhaps you didn't run far enough, or frequently enough. The Scientific American reports that, contrary to the widely held conviction that the more calories we burn, the more calories we want, exercise makes the stomach grow less fond of food. Hunger, it turns out, is a complex sensation, determined in part by neurons which send signals to the brain telling it that you're either hungry or sated. Those neurons get their message from hormones, including insulin and leptin. The magazine reports that researchers found that "physical activity reorganizes the set point of nutritional balance through anti-inflammatory signaling."
To find out how the researchers did it, read more in the Scientific American.
