Carb targets for those on insulin

I was just at my endocrinologist the other week. She recommended no more than 40 carbs for each meal and 20 for a snack. I have been looking at the net cabs/fiber thing when I'm low and also compared to the sugar count. Its hard to find the prefect thing for a low when your freaking out. I have had way more lows then needed recently. 46-55 ugh I had 533 cals just for that alone. Got to love our body fighting against us when we are try to help it in the long run.

When I was starting on insulin, I was told to count net carbs. If I was eating fewer than 15g - net - I could skip the insulin.
Food Guides tend to advocate over 100g of carbs a day - the low carb diets advocate under 30g a day.

You really need to try out different levels of carbs, and adjust for what works in your life. I'd say you can safely go to 50g with no adverse effects, no ketosis, yet reap benefits of lower carbs. I'm not a Dr... so all I can tell you is whats worked for me.

Things to note:
The reason you can (have to) subtract fibre from the total carbs is because the fibre does not get absorbed into your blood - so it does not affect your blood sugar. If you were taking insulin for instance, including those carbs in a calculation for how much insulin to take could make you use too much. So it is important.

I've been on a low carb diet for a month or so, under 30g of carbs, and I have not needed any insulin for the last 3 weeks... nice.
