I've been on the 5:2 diet since February. All was going swimmingly so I decided to up the ante and try a month of 4:3 to really lean down for the summer holidays. The first week or so was ok but a few of weeks in and I'm going to have to return to 5:2. I just can't control my eating on feast days-it's insane, I'm like a crazy person. The psychological impact of fasting for 3 days in the week is just too much. In fact I'm paranoid that I have undone some of my hard work since switching to 4:3
I'm interested to hear if anyone out there had the same experience. I can't believe how much worse I coped on 4:3, particularly as I had no problems whatsoever with 5:2. I read somewhere that there is very little difference ultimately in the weight loss achieved on both these diets. I hope that's true.
Right I'm off to handcuff myself to a chair or have my jaw wired shut.
