What changes the calories
- Size matters most: a small banana (101 g) has 90 calories while a large one (136 g) has 121 calories.
- The weight on the label is for the edible fruit, so weighing a banana with its peel on will overstate how much you actually ate.
- As bananas ripen, more of their starch turns into sugar, which changes the taste and texture but not the calories much for the same weight.
- Drying a banana removes water and concentrates the calories, and frying banana chips adds the calories of the oil they absorb.
Tips for logging it accurately
- Weigh the banana after peeling, or peel it and weigh the skin to subtract it, for the most accurate entry.
- If you can't weigh it, pick the closest size (small, medium or large) rather than defaulting to medium every time.
- Log toppings and pairings separately, such as peanut butter, honey or yogurt, since they can add more calories than the banana itself.
