Question: how many grams of carbohydrates should a diabetic have per day?
Answer: On average, people with diabetes should get about 45% of their calories from carbs. A carb serving is measured as 15 grams per serving. That means most women need 3 to 4 carb servings (45–60 grams) per meal, while most men need about 4 to 5 carb servings (60–75 grams).
