I have been eating/living/moving/sleeping paleo for approximately 6 months, getting increasingly strict with my diet. Now that I am within 5 - 7 lbs of my fat loss goal, I have decided to reduce my carbs to under 50g/day. Am curious as to how much of my initial weight loss is water, and at what point does weight loss reflect fat loss. Thanks. Btw I am 43 yo female 5'2 - 124 lbs.

According to Lyle McDonald, a ballpark re stored glycogen is 500 g (a little over a pound) and for each g of carbs in glycogen there are 3-4g of water. In this case, glycogen would represent 4 or 5 lbs of water. Of course, the amount of stored glycogen actually varies person to person, and the time it takes to deplete it varies too.
Unless your carb intake has been really high, I'd bet you're mostly fat adapted from being paleo for 6 months. So I'd bet you won't see the same quick water weight loss that someone would who'd been eating SAD.
Given that, what I'd say is your weight loss would reflect fat loss right away, but it's hard to say at what point it's predominantly fat loss. Maybe a few days? But maybe it'd be right from the start.
