So I decided to give IF a try - I've been on a 4:3 diet for about two weeks now. I've been able to stick with it, but I haven't experienced (yet) what many report--that fasting gets easier. Does it take longer than 2 weeks? For some, does it just never happen? Yesterday, I nearly went out of my mind until dinner time (when I was rescued by a totally yummy 300 calorie Mexican pizza (recipe from The Book)). I have a very demanding, but not always very distracting job. I can't continue to have days that are unproductive due to hunger. I needed to sit still to read and write yesterday, and I just couldn't concentrate.
Otherwise, it's been going very well. I wavered about whether I should weigh myself (I tend to get too obsessive about things like this); in the end I decided I would go once a week to the health clinic at work for a weigh in (only one so far). I've been doing waist measurements, and have already seen a reduction, which is encouraging.
Sorry for the long post.
As they say in Japan, gambatte!
