Here is my answer to this top weight loss question on Dr. Oz’s Sharecare site:
Water is essential to losing weight and being healthy, yet how much you need varies by individual. Chances are you are not getting enough.
Sometimes when you think you are hungry you are in fact thirsty, it can be a signal from your body to drink. So next time you feel an extra pang of hunger in your day drink water.
How much water should you drink each day? It’s a simple question with no easy answers. Studies have produced varying recommendations over the years, but in truth, your water needs depend on many factors, like how active you are and where you live.
Although no single formula fits everyone, knowing more about your body’s need for fluids will help you estimate how much water to drink each day.
How much water do you need?
On average a healthy man needs about 13 cups while a healthy woman needs about 9 cups. So what about the 8 glasses a day? Think of it as eight 8-ounce glasses a day as a general rule of thumb.
