Vince is in China, are the recipes the same? LOL - just seen his reply, surprise surprise at the 'cost' of the bun! I do that - correlate carbs with money - it's an expensive meal or a cheap one! LOL All burger buns are FAR too dear!
My normal pre diabetic diet was 100g carb a day. It was that because if I ate any more other than occasionally I very soon put weight on, and no I hadn't ever measured any element of what I ate in a day before being diagnosed - no helpful food labelling in those days! But anyway - diet was declared 'properly balanced' by the hospital honchos and that's been that ever since.
If I eat more - I put weight on - I don't have a huge frame, and it just makes me miserable. Been a bit piggy the last couple of months (off my feet with a broken kneecap) and haven't actually dared get on the scales - bit difficult with half your weight on crutches, good excuse so I'm sticking to it! - but bet they'll confirm bad news.
