You really shouldn't be gutted with 2Ib's loss its actually quite good. I have had plenty of losses that low and they always spur me on to wonder what it will be the next WI.. my little surprise lol. Don't forget that there are many factors that effect the weight loss on VLCD, i.e not being completely 100%, totm, how much weight you have to lose, stress, too much exercise ect ect.
Gz on your loss and good luck with future weigh ins!
