Late reply but – you only had 12 pounds to lose and lost on average 3lb per week for the first two weeks and then nothing for the last two. You are still 2lbs “up” on where you should be! With not a lot of weight to lose the loss will always be slower than for people with a couple of stones to come off. It is working fine – and will start to come off again – probably more gradually – very soon. Don’t give up and keep thinking of all those other fantastic health benefits!
