3 carb servings (45 grams of carb) is considered among diabetics to be an awful lot of carb. I was on a moderately low carb diet (about 100 g, or about 6 or 7 "servings" per day) and many folks with type 2 eat as little as 20 or 30 grams (2 "servings") per day. They do this to keep their numbers down. Your meter is the best guide to what you can eat. Many dietitians still follow the outdated notion that you need lots of carb. And this often leads to extra medication or insulin.
