Banana is low in protein: only 4% of its calories come from protein. Most of its calories (93%) come from carbohydrates.
Calculated with 4 kcal per gram of protein and carbohydrate and 9 kcal per gram of fat, so the total can differ slightly from the listed calories.
A medium banana provides about 105 kcal, almost entirely from carbohydrate, which shifts from starch toward sugar as the fruit ripens. Its convenience makes it a common pre-workout snack and a natural sweetener for oatmeal, smoothies and baking. Size matters more than ripeness for calories, so a small banana is a lighter choice and a large one a little heavier.
Typical portion: A large banana of about 135 g peeled works out to roughly 120 kcal, and a small one of about 100 g closer to 90 kcal.
