Try a bowl of whole-grain cereal with low-fat milk and a handful of berries on top with a side of sliced watermelon, or make a smoothie with fruit, soymilk and wheat germ.
4. The Zapper: Dehydration
The Reason: You may not feel like you’re walking through the Sahara, but there’s a good chance you’re mildly dehydrated right now, and even mild dehydration makes you feel sleepy and sluggish. “Many of us walk around dehydrated without realizing it,” King says. “Dehydrated bodies trap toxins and encourage water retention — a natural defense against the chronic ‘drought.’” Remember, your body is about 60 percent water, and there’s no way it can function at its optimal level during a drought.
King’s simple test for dehydration: Pinch the skin on the back of your hand and hold for three seconds. When you release, if the ridge from the pinch remains for more than a second, you’re probably dehydrated.
