Overripe banana has 85 kcal per 100 g. Slightly lower in calories than ripe because overripe bananas lose moisture. The starch has fully converted to sugar, making them ideal for baking.
How should I track Banana (overripe, raw)?
When tracking Banana (overripe, raw), weigh the edible portion — after peeling, coring, or removing seeds. The part you throw away does not count, but it can make up 20–40% of the total weight depending on the fruit. A systematic review (Whitton et al., Adv Nutr 2022) found that fruits are among the most commonly misestimated food groups. One more thing to watch: fresh and dried versions have very different calorie density. A handful of dried fruit can have the same calories as a whole bowl of fresh — always double-check which form you are logging.
