It's hard to believe right now, but soon, summer will be right in front of you. And since a few extra pounds might be right "behind" you, this is good news, because apparently, people are less likely to binge in the sunlight because they feel more self-conscious.

The slimming hormone serotonin plays a role too. It gets a boost from the sun, you see, and just so happens to suppress appetite. Another sunny bonus: The sun kicks in a dose of vitamin D -- and there's no doubt most of us are lacking in this D-partment.

Get ready to head for your sun chair, my friends. It might just get keep you trim. Don't forget your sunscreen, though, because weight loss and a little extra vitamin D are not so valuable if skin cancer comes along for the ride.
