I'm new to this, too, but have also been doing a version of this since last Oct, with very pleasing results.
However, like @TheLeadbetterLife my weight loss has stalled.
The book really explains the science behind this and is a very good read. I also watched That Sugar Film last night, which says very much the same thing, albeit with a rather quirky presentation. I have known about this theory of sugar for some time, having read the books by Kathleen Des Maisons about sugar sensitivity in the 90s. Reading the Jenkinson book has illuminated the lightbulb once more!
Re snacks etc: I am going for hard boiled eggs (do a few in advance and put in fridge) and lovely cheese. Probably rather too much lovely cheese. Saturday is weigh in day for me so we will see if this strategy has worked or not.
Oh and lots of fluid. I have sparkling water, and following a super suggestion on here yesterday, I had some cinnamon tea when sugar cravings hit, and it really helped.
I've eased back on my gym exercise also : am nursing an injured back and also think it could be counter productive in excess- stimulating the appetite. I definitely want to continue with the gym as it's so good for controlling stress. It's odd that I enjoy the gym. I normally loathe noisy environments but I find it's the one place I can successfully zone out. Also, it being three minutes from my door helps!
And then there's the dog walking which is non negotiable:D. I will also go easy on Pilates as I suspect that might have contributed to the back issue .
