how many ounces to drink a day
Here is how to calculate how much water you should drink a day for both health and weight loss benefits. 1  Your weight: The first step to knowing how much water to drink everyday is to know your weight. 2  Multiply by 2/3: Next you want to multiple your weight by 2/3 (or 67%) to determine how much water to drink daily. For example, if you weighed 175 pounds you would multiple that by 2/3 and learn you should be drinking about 117 ounces of water every day.
