I have looked at answers on the internet, but I still don’t get why if someone is exclusively **drinking water** for a period of time, the weight lost is **also water**… which does not provide energy nor is scarce for the body during that time.
Is this real? Why does or bodies behave that way?

The body has two energy sources: glycogen (sugar) and triglycerides (fat). The body can store any amount of fat, in fact it will grow more space if you give it reason to. Sugar storage, however, is limited to skeletal muscle and the liver. The body prefers to use sugar as fuel first and while fasting will do so. The thing about using sugar as fuel is that it takes water to burn it (or store it, I forget) so the body also carries water for that purpose. Once you’ve used up your sugar reserves, the water is used up with it.
Your body still needs water to function, so during water fasting you drink water, but it’s for other bodily functions.
