Banana vs Apple
Straight answer first: for fat loss on a calorie budget, the apple wins on volume — 52 kcal per 100g versus 89 kcal for banana — and its common serving (150g, ≈78 kcal) still lands under the banana's (120g, ≈106.8 kcal). The banana is not "bad": it is the faster, denser energy source, which makes it the better pick right before or after training. The table below shows both fruits per 100g AND per their real default servings, then the verdicts split by goal.

What a real serving looks like
Which one, for which goal
For fat loss
The apple. The rule is transparent: at 52 kcal/100g it carries roughly 42% fewer calories per bite of the same weight, its 150g default serving is bigger in the hand, and the chewing + fiber (2.4g/100g) slow the eating. In a deficit you are managing hunger, and volume is your cheapest currency.
Around training
The banana. 27.6g of carbohydrates in a 120g serving, easy to digest, zero prep — fast fuel before a session or a clean top-up after one. The apple's fructose-and-fiber package releases slower, which serves satiety at rest, not a pre-workout spike.
The sugar question
Neither fruit's sugar disqualifies it from a diet: banana 12g/100g, apple 10g/100g — both arrive inside a whole-food matrix with fiber, water, and micronutrients, not as free sugar. The WHO free-sugar guidance does not count whole fruit. What disqualifies a cut is the total calorie line, not the fruit bowl.
Common questions
Which has fewer calories — banana or apple?
Per 100g the apple: 52 kcal vs 89 kcal. Per their real default servings the gap narrows but holds: a 150g apple ≈ 78 kcal while a 120g banana ≈ 106.8 kcal. Both numbers come from the same database rows this site's food pages use.
Can I eat a banana every day while cutting?
Yes — one banana is ≈106.8 kcal inside a 120g serving with 3.1g of fiber and potassium; a cut that cannot afford a banana was cut too tight. The practical rule: count it in the day's budget like any food, and keep fruit as fruit (whole), not as juice or dried pieces where the calories concentrate and the satiety disappears.
Which fruit is more filling?
The apple, for most people: bigger default serving (150g vs 120g), more chewing, comparable fiber (2.4 vs 2.6 g/100g) at 42% fewer calories per 100g. Satiety research ranks whole fruit high exactly because of this volume + fiber + chewing combination — the banana's edge is energy delivery, not fullness per calorie.
