Smitha,
I'm limiting myself to around 50g a day, but I'm type 1 on an insulin pump. From the threads I've been reading on here so far, I don't think there's a set amount - just as has been previously said, trial and error. Since I started, I've found that if I have more than 15 - 20g cho at any one meal, I bounce up as high as 13 or 14 but if I stick to 10 - 15g cho, I don't peak at more than 8 even if I check just 1 hour after eating. (my specialist recommends waiting 2 - 2.5 hours for a true post-meal reading). I also try to include something with a low GI, so that the carbs are absorbed much more slowly, which should in turn reduce the peak in Blood sugars.
Re carb counting. I'd weigh things for now, so you get the feel of portion sizes. After that, still weigh things now and again - its amazing how portion sizes can grow without you realising. Speaking from experience - I've had diabetes for 31 years, and was soooooo cocky about knowing all there is to know - until I came on this site and discovered the theory of low carbing. As a result, I weighed a 'normal' sized portion of potatoes, rice and pasta, and was horrified to find that the 40g cho I thought I'd been eating was more like 80 - 90g :shock: . As I said - keep a check on yourself and do spot checks now and again!!!!
I've only been low-carbing for 10 days, and I've had absolutely wonderful results .... until I messed up at the gym yesterday and over did the lucozade - shot up to 19.4!!! ouch. :twisted: As a result, I've had rebound lows and then highs all day today - been bouncing between 2.2 and 15.4. Absolutely nothing compared to the old complex carbing range of 1.8 - 33.3, though. I've settled again now and am just trying to take it a day at a time and learn as I go along, as you will too! :wink:
