60% of the time we feel hungry, it is actually because we are thirsty. Many people do not drink enough water on a daily basis. You need about 64 ounces a day or about half or your body weight in ounces of water per day. If it is hot outside or you have been active you will need more. So when it is warm day enjoy a glass of refreshing cold water. But if it is cold outside, opt for sipping on some warmed water to help avoid eating.
I have started drinking water.. Actually my problem is I don't have adequate amount of water at all. Finally, now I am having some water! But strangely, my appetite also increased.
