All of our RD experts agree: H2O is crucial for weight loss. “Water is so important when trying to lose weight since it helps to you feel full between meals,” says Amy Shapiro, RD, founder of Real Nutrition NYC in New York City. Here’s a simple hydration rule of thumb: Shoot to consume half as many ounces of water as your total body weight in pounds. (So if you weigh 180, sip on 90 ounces of water each day.) https://www.youtube.com/watch?v=8GVZYDOBMXk
In addition to all of the health benefits, water will keep muscles full and prepared for action. Lastly when I say water I mean water, not diet pop or other drinks. I hate to break it to you, but diet soda is not so great. One or so a day is ok, but more than that can get in the way of your goals. Coffee is fine, but use regular milk or real cream instead of sugar and the like. Remember that coffee will dehydrate you to a degree so you must drink ample water to replace what is lost.
