I find intermittent fasting quite easy as I never used to eat breakfast anyway. I usually have lunch around noon and my dinner before 6 pm and I don't get hungry until the next lunch time strangely enough. I still eat carbs (sorry, but I can never give up bread) and have the occasional treat or two, but I have basically a fairly healthy diet with plenty of protein (eggs, chicken, lean meat, cheese, yoghurt etc) and bread, pasta, rice, vegies, some fruit. Every couple of days I take magnesium and B12 vitamins.
I don't own a set of bathroom scales so couldn't tell you exactly how much weight I have lost over the last 6 months but I have gone down one clothing size so am more than happy with the results, don't need to see a number.
Have definitely noticed emptying a lot less than I used to, having an ileo this is always a bonus, which is natural enough I guess, the less you eat the less that has to come out!
