Do cravings hit hard after a marathon workout session at the gym? For me, it varies -- sometimes I want to have some lean protein after a sweat session and sometimes I want to eat my body weight in chocolate (but don't worry -- I don't. Well, usually ... ). But as it turns out, there's actually a rhyme and reason to post-exercise cravings.

According to recent studies, the type of workout you do has a tendency to lead to a certain craving. So,

• If you go for a run, you're most likely to crave fruit afterwards.
• If you go for a swim, you're likely to crave high fat or sugary foods, like chocolate.
  
• If you lift weights, you're likely to crave cheeseburgers, pizza or peanut butter sandwiches.
  
• If you go for a gentle walk, it doesn't affect your appetite at all.
  

Of course, it all comes down to evolution -- if you go for a swim in cold water, for instance, your body is prompted to pack on a protective layer of fat. Still, that doesn't mean you should load up on these things -- just be aware and make sure to diet-proof your pantry before your next workout.
