Not standard advise... but the only way I seem to get my weight-loss going again after a stall is to binge for just one night. I suspect my body goes into starvation mode, and giving it what it wants (and then starting induction over again the following day) seems to motivate it to let go off that fat. Maybe take a night or 2 off when your relatives come over (not the entire week though)... and also, make sure you have the willpower to get back on the wagon again before you venture off!

As for your relatives diaspproval... just don't tell them! Make their dinner as carby as they like it.. but keep the carbs off your own plate. I know its hard, but eat fast then run for the kitchen... the dishes will keep your mind occupied (it does mine)!!
