I think initially I used feast days as pig out days (my but it was fun lol) the result is I haven't really lost any weight yet. Well, I've lost weight but then regained it on normal days. Having got the 'pigging out' out of my system I'm now settling down to eating nice but sensible meals on my normal days. Too early to say if this is working yet. I have noticed a recent inability to eat large meals and I definitely get fuller quicker now. I went to a dinner party last week and didn't have much starter, a normal plateful for the meal and could barely manage pudding - which is a huge change for me. Normally I use events as an excuse to go a bit mad.
I've lost 1cm off my waist and I'm losing the anxiety/ panic I had around food. My next step is to start working my way up to 10,000 steps a day.
