Snack: Fruit salad with watermelon and berries
Blueberries are yet another stealth love drug, because their soluble fiber (the non-gassy kind, don't worry) helps clear mood-killing cholesterol. And all types of fruit—but especially watermelon—are full of water, and the more hydrated you are, the better the muscles and tissue all over the body will be to respond to stimulus. Feeling adventurous? Sprinkle walnuts on top of your fruit for an extra dose of fatty acids and L-arginine.
