I have lost 10lbs in weight over 6 weeks on the 5:2 diet. This is amazing as I have either not lost any weight or put in on when doing a conventional diet.
The diet is a bit of a bore to do but not really difficult as one can comfort oneself with knowing that the next day can contain 'naughty' food. Although the tendency is to eat less on the non-fast days.
I have no way of knowing if I am enjoying the health benefits associated with this diet but I am enjoying being that little bit thinner. Although I still have 14lbs to go but am confident that I can achieve this.
