If you're watching your carbs, you'll have a hard time fitting glazed doughnuts into your meal plan. All doughnuts are relatively high in carbs, and the glaze adds even more. The type and size of the doughnut affect the amount of carbs it provides. About half of the carbs in doughnuts come from added sugars, which should be limited to 25 grams per day for women and 37.5 grams per day for men, according to the American Heart Association.
A 3-inch glazed wheat cake doughnut contains 19.2 grams of carbohydrates, while a regular glazed cake doughnut provides 22.9 grams. Opt for a glazed chocolate cake doughnut instead and you'll be consuming 24.1 grams of carbs.
Yeast doughnuts are lighter and fluffier than cake doughnuts, which can lower the carbs a bit as long as you stick with the smaller 3-inch doughnuts. A 3-inch glazed yeast doughnut provides 14.9 grams of carbohydrates, a larger 3.75-inch glazed doughnut contains 30.7 grams and a 4.25-inch glazed doughnut has 35.9 grams.
