1 banana (edible part 89.0g) contains 8 1 calorie, and it takes 55.9 minutes to walk.

The added calories are about 150 calories.

In addition, it depends on the sugar content of bananas. Banana is a high-sugar fruit, which can only be absorbed by liver glycogen. However, the fructose absorbed by human liver glycogen should not exceed 5g per day, and the excess will be stored and converted into fat. So if you eat too much fruit, you will get fat.

The above is for reference only, hope to adopt.
