Drink at least ½ ounce to 1 ounce of water per pound of body weight a day to prevent dehydration, help liberate fat stores to be burned as energy and to flush out waste and toxins. Warm or room temperature water is best to drink as this will not negatively impact your metabolism like cold water will do. Research has also shown that drinking 16 oz. of water 30 minutes prior to every meal, along with a lower Calorie diet, improved weight loss results. Water intake is often cited as the most underrated and overlooked part of fat loss. More or less water intake may be necessary depending upon body weight and food consumption. High quality spring water in glass bottles is your best option, but make sure that your water is at least filtered to eliminate impurities like excess chlorine and fluoride which negatively affect the thyroid.
