Most cravings are actually misinterpretations from our bodies that we are dehydrated. By drinking a tall glass of water first, you may be giving your body exactly what it wants and alleviate the craving altogether. By some estimations, 80 percent of people are chronically dehydrated. So, before you reach for food to nix your cravings, quench them with some water. Then wait half an hour. More often than not, they’ll be gone.
