hey seigns, sorry to hear you had a gain this week. like kate said - is it that time of the month?
it could be lots of things that have done it - like not drinking enough water (and retaining), maybe not eating enough? i think from memory you're doing the optifast program? i'm not sure if maybe other people have had the same experience?
either way, i'm sure if you're doing everything you're meant to, that the weight loss will start up again
