this statement. "Certain fruits, like watermelon, contain a lot of water, but they also contain a sugar that enters the bloodstream really fast. The excess sugar is rejected in the urine with lots of water. Therefore, the water contained in watermelon is not even enough to handle the sugar in it. That is why if you go on a watermelon diet you can feel dehydrated, which sounds unbelievable, but it happens. The key to watermelon is to drink some water before or after eating it."
