Can't See A Thing

At the end of week 3 I'm 3kg down. I can't see where, though. I'm 156cm and my starting weight was 68kg. Usually for my height you can really see a 3kg loss but not this time. Perhaps because I started off more overweight than I've ever been so when there's more to lose its less obvious in the beginning? Idk . . . I am a tad disappointed but I guess a 3kg loss when you had 8kg to lose is pretty good? Doc wants to get me down to 60kg. Hope to be there by early March.
