I struggled in week three too, it's common, I also find that my week 3 weight loss is less than the first two weeks, if that happens don't let it put you off, my CDC said it's just a sign that your body has settled into the VLCD and it usually picks up the following week. (lol don't look at my losses this time round I'm stalling big time for some reason. But first couple of times I had great losses!!)
