Ask any urologist and the bottom line is you need to produce 2 to 3 quarts of urine a day in order to effectively flush out the kidneys. This equates to consuming 2.5 to 3.5 quarts of water per day for the average adult. If a person sweats more through work, activity or sports, then more water is necessary to achieve the 2 to 3 quarts of urine daily. BTW, this is not a good website to harvest good health information from. Also, "calorie reduction diets" as the one suggested by the original poster fail in the long run the vast majority of the time. Eliminating "high carb low nutrient processed foods" from the typical American diet will go a long way in helping most people achieve a BMI appropriate weight for the long term.
