Exercise After Eating
From BBC Health News:
Exercising after meals can help promote weight loss by boosting hormones that suppress appetite, say UK scientists.
Thanks to these hormones, active people feel less hungry immediately after exercise, and this carries through to their next meal, experiments suggest.
Even when their meals were bigger, sporty people gained fewer calories overall because they burned off more.
The Surrey University and Imperial College London work is published in the Journal of Endocrinology.
Exercise may alter people’s appetite to help them lose weight
Twelve volunteers were fed the same breakfast.
An hour later, half of them worked out for an hour on an exercise bike while the other half sat quietly.
Both groups were left for another hour and then allowed to eat as much as they liked.
Unsurprisingly, people who exercised burned more calories than those who sat quietly, 492 kcal compared to 197 kcal.
And when given the chance to eat afterwards, people who had exercised tended to eat more, 913 kcal versus to 762 kcal.
However, when the amount of energy burned during exercise was taken into account, the sporty people took in fewer calories overall – 421 kcal compared to 565 kcal for the inactive group.
And levels of hormones called PYY, GLP-1 and PP, which tell the brain when the stomach is full, increased during and immediately after exercise.
Volunteers also said they felt less hungry during this time.
Researcher Dr Denise Robertson said: “In the past we have been concerned that, although exercise burns energy, people subsequently ate more after working out. This would cancel out any possible weight reduction effects of exercise.
“But our research shows that exercise may alter people’s appetite to help them lose weight and prevent further weight gain as part of a healthy, balanced lifestyle.”
My comment: We keep hoping we can lose the weight with no sweat, but it seems like everywhere we turn, the secret seems to be . . . eat less . . . exercise more. You can read the rest of the story HERE.

ok so now few months a paper was released about walking 10-30 minutes before each meal can boost the metabolism…
and now after meals too..
it means one should drink water, workout, eat, work out, drink water … to compensate with six “10 minutes” of cardio a day (equals to an hour of walk) and eight glasses of water a day (for a normal three meals eater and a snack )
Don’t you love nutrition 🙂
All this tells us is that exercise burns calories. The study only used 12 people– unfortunately, the media don’t usually scrutinize research methods or the true implications of findings very much.
Judy, yeh, it’s ironic, isn’t it, how much you have to THINK about and how much time it takes. And that’s not to lose weight, but to just stay fit. Aarrgh. I keep hoping for a magic pill that just melts it all off.
Marzapane – yeh, and they probably got a huge grant to come to that conclusion. . . go figure.
My conclusion: I’m not normal 😀 coz i actually build up a huge appetite after i exercise…ok fine i have only exercised 3 times in my life 😀
I just stumbled on the solution to my diet problems. This is what had been missing from my life: http://villeki.aqua-web.org/paskaa/vesi.jpg
Oh Magical, I am dying laughing. And I bet people BUY it, too!
The best I ever had it was doing aqua aerobics with a few close friends. We laughed and talked so much we hardly realized we were exercising, and we solved all the problems of the world. Wish we had that here!
as a “sporty person” myself I must say that the last thing I want to do after eating a full meal is have a big workout.
on the other hand, going for a stroll after eating – whether through the city streets or in a mall – to me seems a delightful way to digest one’s lunch or dinner. Its not exactly a “workout”, but it is exercise!
It seems to me a life style change is in order. One thing we know is that people often revert back after reaching their weight loss goal. A life style change will solidify an ongoing weight loss and will almost guarantee it is kept off
