Just heard about the book (here in the US) and read it all in one fell swoop, even watched the video--not too much difference from the book I realized but it proved interesting to have the material reinforced.
I've fasted before so don't think I will have any problem with one day--in fact, that is what attracted me to this method. I know I can cut off my hunger feelings, but what is new for me is actually eating some little thing during the day. I had some oatmeal porridge in the morning and think I'll have some soup later in the day, complemented with a few cups of black java, haha. Looking forward to all the great health benefits and believe that this 5-2 approach will be easier to maintain over longer periods of time.
My biggest challenge will be knowing how much to eat at any one time on the fast day. I'll go back and look at the pictures of portion size again, haha.
