The New York Times has a story on whether walking or running is better for health, and one of the observations is that running is better for weight control. Running, it turns out, is more of an appetite suppressant, which is something I’ve always know for myself. IN one experiment, they let people loose in a buffet after walking or running:
The walkers turned out to be hungry, consuming about 50 calories more than they had burned during their hourlong treadmill stroll.
The runners, on the other hand, picked at their food, taking in almost 200 calories less than they had burned while running.
