All carbohydrates (either from sugar or starch) will raise blood sugar to a similar degree. In general, one gram of carbohydrates raises blood sugar by 3 points in people who weigh 200 pounds, 4 points for weights of 150 pounds, and 5 points for 100 pounds.

Of course, adding fiber and eating low on the glycemic index will moderate this blood sugar rise. But the formula can be used for a thumbnail approximation of how many carbs to eat at a time if you are diabetic.

Hi,

I'm type 2. I weigh 191 lbs and am pretty active physically. I try to eat only low GI food. My BG seems to rise about 1-2 per g of carb.

I find the formula works reasonably well for me. But bear in mind that it only applies to people who are totally dependent on injected insulin. So the formula won't work for T2s and T1.5s who still have some beta cell function. When they eat carbs, insulin is produced, moderating the blood glucose rise.
