Trying to lose weight? Here's a neat trick from BBC 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.

New Kerela.com says about after eating exercise:

The researchers reported that though unsurprisingly they had found that people who exercised not only burnt more calories and ate more than the people who sat quietly, what was surprising was that when the amount of energy burned during exercise was taken into account, the ones who exercised took in fewer calories overall - 421 kcal compared to 565 kcal for the inactive group.
