How this fits a day of eating
A medium banana (118g) is about 105 calories, just over 5% of a 2,000 calorie day, almost entirely from carbohydrate. It is a convenient, pre-portioned snack that works well before exercise, and its fibre and natural sugars make it more filling than the same calories from sweets.
Ripeness changes the taste more than the calories. As bananas ripen, starch converts to sugar, but the total calories stay about the same, so log a spotty banana exactly like a green one.
Common questions
How many calories are in a banana?
A medium banana about 18 to 20cm long weighs around 118g without its peel and contains roughly 105 calories, 27g of carbohydrate and 3g of fibre. A small banana of 101g is about 90 calories, while a large one of 136g is close to 121 calories.
Do bananas make you gain weight?
No single fruit causes weight gain. A medium banana has about 105 calories, less than many packaged snacks, and provides fibre, potassium and vitamin B6. Weight changes depend on total calories over time, so bananas fit easily into a calorie deficit when they replace, rather than add to, other snacks.
Is a banana a good pre-workout snack?
A banana is a practical pre-workout snack for many people. A medium one supplies around 27g of mostly quick-digesting carbohydrate for about 105 calories, is easy on the stomach, and needs no preparation. Eating it 30 to 60 minutes before training gives time for digestion while still providing usable energy.
How many calories are in 3 medium bananas?
1 medium banana has about 105 calories, so 2 medium bananas come to roughly 210 and 3 medium bananas to 315. The same maths keeps going: 5 medium bananas are about 525 and ten about 1,050. Use the quantity calculator above for any number up to 20.
