KiaKaHa,
I am posting a good website below: It can let you know your Base number of calories needed daily and can help you determine about how much you should eat to produce weight loss without starving yourself. I'd suggest though, like anything else, modify and tweak it to fit you... This is just a small part of the whole picture when it comes to controlling diabetes. I've learned to never depend on one thing but on a combination of many things to achieve better health.
There's a website for which I posted a link a while back and it talks about how we're all somewhat different, but we can all start at a common point and start from there and modify our diets to what works best for us.
When I was at my peak weight, my carb tolerance was about 10g per day. As my health improved, it gradually increased. I'm able to tolerate 100g-150g per day now and stay in control, but it was a long road getting here, with lots of trials and experimentations.
You asked; "Does it mean I can eat bread sometimes?" I think the answer is maybe, but considering your current stats, you're probably at a point of very low carb tolerance and should probably avoid breads for now.
When you're not sure how a food will affect you, eat it, test yourself at one and two hours afterward and if you get negative results, you will then know what not to do again, right?
I've become a strong believer in eating when my energy feels low and not wait to eat when I am hungry. I also believe that restricting calories below your base rate needed each day is countrer-productive.
Diabetes is a metabolic disorder and everything we do should include trying to increase our metabolism. That is just my opinion based on my experience, not derived from science.....
