Experts are always saying that when we first start dieting that it’s the water weight that’s lost meaning it’s not fat or muscle. Can you explain what this water weight is exactly and where does it come from?
What would be the approximate normal amount of “water weight” that’s lost in an average male of say 175lbs and 510″ and a woman of 167lbs and 5 6″
Is this “water weight” the weight that can fluctuate within a 24 x hour or 48 hour period?

In addition to the other answers, another source of lost “water weight” comes from changes in salt intake. If you start eating healthier food, you are probably taking in less salt (mainly sodium) than before. Human bodies are made up of mostly water, and that water needs to stay within a pretty narrow range of saltiness. Our kidneys try to regulate our bodies’ salt levels by controlling how much salt goes into your urine vs. stays in your body, but this isn’t an instant process. So if you eat a bunch of extra salt above your usual intake, you will need to drink more water to keep the overall salt concentration in your body the same. If you eat less salt, your body will get rid of more water via urination for the same reason.
