Welcome Margaret! In answer to your question, no, you don't need to count fat/carbs if you follow the book. However, I will say that after 'real life' begins to creep in, it has been very helpful to some of us long term BSDers to have a carb allowance, and aim to keep under 50g, because inevitably there will be times when you will have some carbs, so it's helpful to have a boundary. I will also add that this time, which is my second proper round but third attempt, I have followed the book principles more strictly- (so no pasta, rice, potatoes, bread/grains, sugar) and I haven't needed to count carbs because those are the things that push the carbs up. If you stick to 800 calories, and avoid those foods, it's pretty hard to exceed 50g carbs anyway.
Ironbridge museum was very good, lots of walking. I had a few samples of the delights, (a square of fudge and dh and I shared a piece of fish from ye olde chippy) but all things considered I didn't do too badly. Yesterday not so good, I went totally off plan, probably as a result of Thursday's little tastes of the good stuff.
Today, I've been on plan except for a taste of chocolate fudge icing as I made my Easter cake. Tomorrow, I'm writing off. I'm doing a big roast lamb dinner which shouldn't be too horrific carbs wise, but I will be having an Easter egg, so.......I expect a pound or 2 gain on the scales on Monday. It's annoying too because I'm teetering around the 11.13/12.1 zone and this weekend will inevitably tip me back into the 12s.
I feel like I've found my mojo though, and definitely keeping totally off the 'big 5' has helped me keep on it. I never really gave up the grains before, I'd have porridge or a Ryvita or two for example, but haven't this time and it seems to help.
