Hi there fulltank You can generally expect to lose 10% of your fat during the first month and about 5% every month thereafter (withstanding any stalls / plateaus). While a lot of what you lose at first is water, there is also some fat in amongst it.

Ann is right - try to weigh yourself at the same time every day (preferably first thing in the morning before any food) and in the same clothing (or w/o ) for accuracy.

Cheers,
Nat
