Q. How many calories does the average banana have?
Most bananas have between 100 and 120 calories. However, because no two bananas are exactly the same, there is no definite answer.
A medium banana of about 7 inches (including the peel) is about 100 calories. A larger banana of 8 inches has about 120 calories.
If you have a smaller banana of only about 6 inches, figure on about 90 calories.
