As anyone who's left a sweaty gym sesh and headed straight to Woolies to stock up on Tim Tams and Twisties well knows, the struggle to not overcompensate for burned calories is real. The good news, according to a new study, is that you're not just being greedy; but the bad news is, you're going to have to fight science to resist temptation.

Published in the Journal of Health Psychology, the study, titled Acute aerobic exercise increases implicit approach motivation for dessert images, found that exercise made participants more likely to crave dessert. NY Mag reports that the study tested 88 college students via an "approach avoidance task:" first, they were shown images of desserts and random objects and their immediate response to each was measured by their hand movements on a joystick (if they inadvertently pulled the joystick towards them that indicated positive feelings to what they were seeing).

Next, half the participants were told to exercise while the other half completed memory puzzles before they all repeated the joystick test. The result? The exercisers were more attracted to dessert images the second time round. But hey, they deserved it.

So this is why you want to eat more after exercise
