A medium banana has about 105 calories. Bananas (kela) are fat-free, naturally sweet and packed with potassium and fibre — one of the most popular everyday fruits in India. The exact calorie count depends on size, so here's the full breakdown along with carbs, sugar, fibre and protein.
Values are approximate averages based on USDA data for a raw, ripe banana. Small Indian varieties such as elaichi (yelakki) bananas are lighter — about 60–80 calories each.
Banana Calories by Size
| Banana size | Weight | Calories (kcal) |
|---|---|---|
| Elaichi / small (yelakki) | ~60g | ~70 |
| Small (15–18cm) | ~101g | ~90 |
| Medium (18–20cm) | ~118g | ~105 |
| Large (20–23cm) | ~136g | ~121 |
| Extra large (> 23cm) | ~152g | ~135 |
Per 100g, a banana has about 89 calories. A sliced cup of banana (~150g) is roughly 134 calories.

Almost all of a banana's calories come from carbohydrates — mostly natural sugars and starch — which makes it a great quick energy source before or after a workout.
"A medium banana is about 105 calories of fat-free, potassium-rich fuel — one of the simplest healthy snacks you can carry anywhere."
Does Ripeness Change the Calories?
The total calories barely change as a banana ripens, but the type of carbohydrate does:
- Green / underripe: more resistant starch, which acts like fibre and is digested more slowly — gentler on blood sugar.
- Yellow / ripe: the starch converts to natural sugars, so it tastes sweeter and is digested faster.
Either way, you're looking at roughly the same ~105 calories for a medium banana.
Is Banana Good for Weight Loss?
Yes — bananas are fat-free, high in fibre and potassium, and naturally portion-controlled. The fibre helps you feel full, and they make a convenient swap for fried or processed snacks. As with any food, they fit a weight-loss diet as long as they're part of a calorie-controlled day.
