No, there is no proof that coconut water can help you lose weight. Although low in calories – 46 calories for a cup – there is nothing special about coconut water that helps with weight loss. As in the previous blog, if you choose to drink coconut water, read the label! Make sure there is no added sugar or fruit purée. These ingredients would make coconut water higher in calories. (Coconut water has about a teaspoon and a half of natural sugar.) By the way, coconut water doesn’t cleanse your kidneys or help your mental clarity either as some websites claim.
