I think it is pretty much common knowledge that increasing carbs makes you retain water, and when you go low-carb you lose a lot of that water. And therefore, if you low-carb most of the time and have a high-carb day, you'll gain several pounds of water weight.
Here's my question: are carbs from fruit the same--do they make you retain water? I've never eaten fruit and WITHOUT eating other carbs in order to observe whether i retain water or not. If i don't care that much about eating low-carb, but i just don't want to be bloated, would it work to eat a lot of fruit on a daily basis, and then eat junky carbs once a week? For example, let's say i eat 3 pieces of fruit every day, and then once a week i eat a slice of cake with sugary frosting...or 3 cookies or whatever (you get the idea). In the past, cookies or cake would have made me retain water because i didn't eat carbs most of the week. But if i had been eating fruit all week, would i not retain water from the cake? Or would i have just been bloated the entire time from the fruit?
