Hi Susie, I think the lack of choice during the day makes it quite easy to stick to, I can either have a shake or a bar, if I want to chew. Having a meal in the evening means I don't feel deprived, I am keeping the evening meal between 400/600 cals, trying to keep the evenings lowish carb, but if I want potatoes rice or fruit I can have them. I am not banning any foods, although keeping away from bread as much as possible, as it is definitely my major trigger, also I find if I eat carbs in the evening they don't affect me as much, if I eat carbs earlier in the day I just want to keep eating them....but is early days yet! I will be very happy with a loss of 6lb a month (after this initial water loss). I will be interested to see how you get on. Are you only doing shakes?
