Water weight is a common annoyance; and if you don't control fluid retention, water can add several pounds to your body weight. Gravity affects fluids in the body. As a result, fluids tend to settle in the lower half of the body and add weight to the legs and thighs. Fortunately, there are ways to lose water weight in the legs and slim your thighs.
Eat fewer carbs and add potassium-rich foods to your diet. Both carbohydrates and potassium affect the way your body balances water. Water binds to carbs, and lack of potassium in your diet reduces the amount of water your body flushes naturally. Reduce your carb intake and increase your intake of potassium-rich foods such as bananas.
Consume low-sodium foods. Sodium (usually eaten as salt) is a dietary factor that affects water weight in the legs and thighs. Eat fewer than 2,400mg of sodium a day to stop dehydration and fluid retention. Read food labels before purchasing and reduce your intake of processed foods.
Drink plenty of fluids. Dehydration results in water weight because your body goes into survival mode and starts storing fluids, as opposed to flushing fluids. Increase your water intake, and drink at least eight glasses or 64 oz. a day.
Fight water weight with exercise. Being active and engaging in regular workouts prompts perspiration and the release of extra water. In turn, your body loses fluids in the legs. Aim for 90 minutes (at least) of physical activity a week.
Find an alternative drug. Medications are common water weight triggers—such as birth control pills and corticosteroids. Ask your doctor to taper your dosage, which may combat or reduce fluid retention in the legs; or inquire about alternative/natural treatments.
Take a diuretic. Over-the-counter and prescription diuretics stimulate the kidneys and help the body release stored water. Experiment with a diuretic, and take the medication as directed.
