4. Ice
Water is the best diuretic out there as we’ve already seen, being much safer and healthier than other approaches. But if you want to get even more bang for your buck, then add in some ice. This way you’ll speed up the metabolism more because the body will work harder in order to warm itself back up. Cold ice water can also be used this way to encourage weight loss. Throw in a slice of lemon and you have three diuretic properties working together!
