Reduce Your Sodium Intake An excess of sodium will cause your body to retain water. Lower your intake by avoiding instant and processed foods like canned soup, boxed macaroni and cheese, and frozen dinners, as well as high-carb foods like pizza, bagels, and French fries. When selecting condiments, opt for lower-sodium versions. Eat fresh foods whenever possible. Incorporate Foods With Potassium Foods like sweet potatoes, greens, tomatoes, oranges, bananas and cantaloupe contain potassium, which helps to counter the effects of sodium and can lower your blood pressure. Control Portion Sizes When you reduce your caloric intake, you reduce your sodium intake too. Make sure to keep meat servings no larger than the size of a deck of cards. Try eating only half of large restaurant meals and taking the rest to go. Drink Plenty of Water Drinking water actually reduces water weight. You should drink half your bodyweight (in pounds) in ounces of water daily to stay properly hydrated. For example, someone who weighs 150 lbs should drink 75 ounces of water every day. Drink whenever you feel thirsty. Eat Hydrating Foods If you grow tired of drinking water you can contribute to your daily intake by incorporating water-filled fruits like strawberries, cantaloupe, and watermelon into your meals. You can also add celery, asparagus and spinach to help with hydration. Exercise Regularly Working up a sweat allows your body to rid itself of excess water, so you’ll lose water weight as soon as you start to perspire. For an extra sweaty workout, try high-intensity interval training.
