A medium apple has about 95 calories. That’s for a whole apple with the skin on, weighing roughly 182 grams (about 6.4 ounces). Smaller apples come in around 77 calories, while large ones reach approximately 116 calories. The exact number shifts depending on variety and size, but most apples you’d grab from a grocery store land in that 80 to 100 calorie range.
Full Nutritional Breakdown
Nearly all of an apple’s calories come from carbohydrates. A medium apple contains about 25 grams of carbs, 19 grams of naturally occurring sugar, and 3 grams of fiber. Fat is essentially zero, and protein is minimal at around 1 gram. That 3 grams of fiber is worth noting because it means roughly 12% of the carbohydrate content passes through your digestive system without being absorbed as energy. Most of that fiber lives in the skin, so peeling your apple cuts the fiber content significantly.
The sugars in apples are a mix of fructose, glucose, and sucrose. Unlike added sugars in processed foods, these come packaged with fiber and water, which slows down how quickly your body absorbs them.
Why Apples Don’t Spike Blood Sugar
Despite having 19 grams of sugar, apples have a glycemic index of just 39 (out of 100) and a glycemic load of 6 per serving. A glycemic load under 10 is considered low. For context, white bread scores around 75 on the glycemic index. The fiber and polyphenols in apples slow digestion enough that sugar enters your bloodstream gradually rather than all at once. This makes apples a solid fruit choice if you’re watching your blood sugar levels.
How Size Changes the Count
Apple sizes vary more than most people realize. A small apple (about the size of a tennis ball, around 149 grams) has roughly 77 calories. A medium apple, the size typically referenced on nutrition labels, sits at 95 calories. A large apple (223 grams or so) pushes toward 116 calories. If you’re tracking calories precisely, weighing your apple once or twice gives you a better baseline than guessing, since what one store labels “medium” can easily be another store’s “large.”
Calories by Variety
The calorie difference between apple varieties is smaller than you might expect. Sweeter varieties like Fuji and Gala tend to have slightly more sugar and therefore a few more calories per gram than tart varieties like Granny Smith. In practice, though, the difference between a medium Fuji and a medium Granny Smith is only about 5 to 10 calories. Size matters more than variety when it comes to calorie count.
Raw Apples vs. Applesauce
A half-cup serving of unsweetened applesauce contains about 51 calories, 13.7 grams of carbs, and 1.3 grams of fiber. That sounds lower than a whole apple, but the serving size is smaller and you lose a good portion of the fiber during processing. You’d need roughly two servings of applesauce to match the volume of eating a whole apple, which brings the calories close to the same while delivering less fiber. Sweetened applesauce adds considerably more sugar and calories on top of that.
Whole apples also take longer to eat than applesauce, which gives your body more time to register fullness. If you’re eating apples specifically to feel satisfied between meals, the whole fruit is the better choice.
Apple Juice Is a Different Story
An 8-ounce glass of apple juice has about 114 calories and virtually no fiber. The juicing process strips out the pulp and skin where most of the fiber lives, leaving behind concentrated sugar water. Your body processes juice much faster than a whole apple, so you get a quicker blood sugar response and less lasting satiety. Calorie for calorie, a whole apple keeps you fuller for longer.
How Apples Compare to Other Fruits
- Banana (medium): 105 calories, higher in carbs
- Orange (medium): 62 calories, similar fiber
- Pear (medium): 101 calories, slightly more fiber
- Peach (medium): 59 calories, less fiber
Apples sit in the middle of the pack for fruit calories. They’re not the lowest-calorie option, but their combination of fiber, portability, and long shelf life makes them one of the most practical everyday snacks. A medium apple with a tablespoon of peanut butter adds about 95 calories of fat and protein, bringing the total to roughly 190 calories with a much better balance of nutrients to keep you satisfied.
