I know why I regain weight EVERY time, regardless of what diet I'm on...I take my eye off the ball. I'm really good at stuff when I'm focused on it and it's my priority, but when I lose weight it stops being my priority, and then something else takes over, and then I gain a little, then I think "I'll start again tomorrow" which turns into the next day etc...
I'm such an all or nothing person (which is why this diet appeals!) but this time I need to master the art of looking after myself and juggling more than one priority. Not sure how I'm going to achieve that yet but I am NOT going to spend my forties like my twenties & thirties...yo-yoing up and down, wearing my emotional state on my waistline.
