Yeah he did do it for a week before bit after third day he was eating one protein meal a day instead of 3rd shake , he then stopped and did a low carb diet like atkins .. According to our bmi we could do with loosing 5 stone each but I think we would look miserable ha ha ..taking each week as it comes , not easy , I'm not hungry it's just the smell of food ,, def here at least another 4 weeks
