Ginger has the ability to speed up the time it takes your stomach to pass food to your digestive tract by up to 50 percent. Add ginger to your meal, and you can say so long to that full feeling in your gut and hello to that full feeling in your pants sooner. Ginger tea works, pickled ginger is great, or just a half thumb of peeled ginger boiled into a tea, or even raw, will do the trick.
