I think it was Bob on the Biggest Loser who said you are entitled to at least one day of luxury - he said that as long as the majority of the week is controlled it does not matter. I think your luxuries are still within the range of controlled to be quiet truthful. I tend to fall into huge luxury column i am afraid sometimes and then have a bad habit of feeeling i need to make it up. And I think we need to be focused not finatics lol... I agree with sticking to one set of scales but if you wish to use both go ahead just work out what you think is most accurate. It may to you not be either, it might be inbetween the two. You seem to have a good idea of where you are at but be pleasantly supprised by extra bonus's too.
On the road to losing weight for the second time, hoping for 20kg off for Christmas and to make it a life change this time.
