Excercise, baby!

Yeah, as we been saying, like forever, studies published in The International Journal of Obesity and PLoS One say this:

Their appetites were noticeably blunted by each of the interval workouts, and in particular by the most strenuous 15-second intervals... They also displayed significantly lower levels of the hormone ghrelin, which is known to stimulate appetite, and elevated levels of both blood lactate and blood sugar, which have been shown to lessen the drive to eat, after the most vigorous interval session than after the other workouts... And the appetite-suppressing effect of the highly intense intervals lingered into the next day, according to food diaries that the men completed.
