I kinda noticed this, too, after sunbathing last week. Totally chowed down on fruit!
I was going to lay off of my injured foot this weekend, but the beautiful day and boundless energy beckoned me. So, I put on my Skechers' Shape-Ups (bought pre-primal, but nice cushioning for my foot) and took my dog, Murphy, to the Dog Park.
Had a great time, some sunshine, a nice walk and throwing the ball in the pond for the dog to retrieve--nothing very strenuous. I probably spent more time in the sun than I should have and I'm very fair skinned (freckled).
I ate a good breakfast of eggs and bacon and was not hungry, but when I got home, I was craving carbs and sugar so bad, I was almost shaking (I'm now on Day 28 and haven't had any real cravings until today). So I chopped up half an apples, some strawberries in a bowl and tossed with pecan pieces and ate it all and now feel so much better. I listened to my body and ate what it told me to.
So was it the sun? I'd be really surprised if it was the small amount of exercise that I got.
Same, I just spent the afternoon outside in the sun, came home and ate a couple of eggs, they didn't do the trick, ate a pear, now its all good.
