water loss - weight loss conundrum

[indigo88]

What happens to the body chemistry that means that early weight is considered to be water loss?

I think!!! its because your body stores available energy as glycogen and that is stored on a 1/4 ratio with water molecules. So when you use your readily available energy in your muscles and liver, you also get rid of 3 times the amount of water. Hence a big drop in weight in the first week or two of dieting but its not fat loss and isnt sustainable.

Ah! All becomes clear. Thanks.

Princess has explained it very well.
