The natural lowcarb store bars are between 3 and 5 grams of carbs, lots of coconut and seeds, only sweetened with inulin/fructo-oligo-saccharide, which suits me fine. Highly recommended as a treat 3 or 4 times a week.
I've nothing but admiration for people on the forum who seem to stay at 20-30g carbs, and also eat healthily. However, for me, having never eaten fruit/veg/salad, my version of lowcarb has to incorporate some lowcarb versions of the foods I have always eaten. So, i have the occasional box of microchips with my lump of meat for my evening meal, chicken kiev covered in cheese and bacon, despite knowing the breadcrumbs will spike me a bit etc. I aim for less than 7.7 post-prandial readings, but go over this 2 or 3 times a week. about once a fortnight on average my BG goes up to 11 or 12, if I join in with a family roast dinner or take away, have friends over etc, but reduced portions of the carbs.
My treat most days is 6 or 7 strawberries, loads of splenda and erythritol to sweeten, + double cream, extra thick double cream and clotted cream - about 600-700 calories, but perfect LCHF food.
Everyone has to do it their way. I think the higher my cholesterol is the better (from reading malcolm kendrick + others), and don't believe fruit and veg are an essential part of anyone's diet. I eat loads of nuts now. i couldn't survive without my low carb bready things (+ gives me fibre) and artificial sweeteners (which I know a lot of people feel are unhealthy). However, I'd rather stick to what I'm doing and keep my Hba1c down near 6. If I try to restrict myself more, I know that I will have a major pig-out, which i have so far avoided (apart from a 120g bar of cadburys + daim 2 months ago, which set me back for a day or two!!)
hope this is helpful.
