6. Take diuretics.
Diuretics help to decrease fluids in the body through urination, and although you can take them in the form of medication, you can just as easily find them in food. Onions, beans, leafy greens, pineapple, parsley and grapes are foods that act as diuretics, according to Livestrong. Coffee is another quick way to increase urination and decrease your fluid retention, although caffeine can cause other side effects, too.
7. Get your daily potassium.
Potassium is another natural way to increase urination and decrease fluid retention, notes Livestrong. All meats are a good source of potassium, as well as broccoli, peas and potatoes, and a number of fruits, milk, yogurt and nuts.
