How Many Calories in an Apple? By Variety, Size, and With or Without Skin

The quick answer: A medium apple (about 182g / 3 inches in diameter) contains approximately 95 calories, with 25g of carbs, 19g of sugar, 4.4g of fiber, and 0.3g of fat. Apples are one of the most widely consumed fruits in the world, and their high water content (86%) and fiber make them one of the most filling fruits per calorie.

Calories in an Apple by Size

Apple sizes vary significantly, and so do their calorie counts.

The difference between a small and large apple is about 39 calories. While not dramatic for a single apple, people who eat an apple daily will accumulate about 14,000 calories over a year from size differences alone — roughly 4 pounds of body weight.

Most nutrition databases default to the medium apple (95 cal). If the apples you buy are consistently larger than a tennis ball, they are likely in the large category (116 cal).

Calories by Apple Variety

Different apple varieties have slightly different sugar levels, which affects their calorie count.

Granny Smith apples are the lowest calorie variety at about 80 calories per medium apple, primarily because they contain less sugar than sweeter varieties. Fuji apples are among the highest at 100 calories due to their higher sugar content.

That said, the calorie difference between the lowest and highest variety is only about 20 calories — not enough to base your apple choice on. Choose the variety you enjoy eating, since the nutritional differences are minimal.

With Skin vs Without Skin

Apple skin contains a disproportionate share of the fruit's nutrients.

Peeling an apple removes about 18 calories and half the fiber. It also removes most of the quercetin, an antioxidant concentrated in apple skin that has been linked to anti-inflammatory and antihistamine effects.

The bottom line on peeling: Unless you have a specific digestive issue that makes apple skin problematic, eat the skin. You save a trivial number of calories but lose significant nutritional value.

Full Nutritional Breakdown

Here is the complete nutrition for one medium apple with skin (182g):

Apples are not a powerhouse for any single vitamin or mineral, but they provide a solid base of fiber, vitamin C, and potassium. Their real nutritional strength is in their polyphenol and antioxidant content, which does not appear on standard nutrition labels but has been extensively studied for health benefits.

The Science Behind "An Apple a Day"

The old saying has more science behind it than you might expect:

Satiety: A 2009 study in the journal Appetite found that eating a whole apple before a meal reduced total calorie intake by 15% compared to eating apple sauce or drinking apple juice with the same calories. The fiber and the act of chewing whole fruit create greater fullness signals.

Weight management: A Brazilian study followed women who added 3 apples per day (285 cal) to their diet for 12 weeks. Despite the added calories, they lost an average of 2.7 pounds, likely because the fiber and volume of the apples displaced higher-calorie snack foods.

Gut health: Apple pectin (a type of soluble fiber) acts as a prebiotic, feeding beneficial gut bacteria. A healthy gut microbiome has been increasingly linked to better weight management and metabolic health.

Apple Products and Their Calories

How you consume your apple dramatically affects the calorie equation.

The standout comparison: a fresh apple has 95 calories with 4.4g of fiber and keeps you full for 1-2 hours. A cup of apple juice has 114 calories with almost no fiber and barely affects hunger. Whole fruit is almost always a better calorie investment than its processed alternatives.

Apples in Meal Planning

Apples are one of the most convenient snack foods for meal planning: they require no preparation, travel well, stay fresh for weeks in the refrigerator, and come in their own packaging.

Apple Snack Combinations

Pairing an apple with a protein or fat source creates a more balanced snack that sustains energy for 2-3 hours instead of the 30-60 minutes you get from the apple alone.

Apples at Different Calorie Levels

Apples vs Other Fruits

Apples rank in the middle for calories among common fruits. They are not the lowest (strawberries and oranges win there) or the highest in fiber (pears beat them). Their advantage is a combination of decent fiber, long shelf life, portability, and year-round availability that makes them one of the most practical daily fruit choices.

Frequently Asked Questions

Are apples good for weight loss?

Yes. Apples are one of the best fruits for weight loss because of their high fiber content (4.4g), high water content (86%), and relatively low calorie density. Research shows that eating a whole apple before a meal reduces total intake, and the fiber promotes lasting fullness. At 95 calories for a medium apple, it is one of the most satisfying snacks per calorie available.

Do apples have too much sugar?

A medium apple has 19g of sugar, which sounds like a lot but is entirely naturally occurring. This sugar is packaged with 4.4g of fiber, water, and polyphenols that slow absorption and prevent blood sugar spikes. The glycemic index of a whole apple is about 36 (low), meaning it has a gentle effect on blood sugar. The World Health Organization's sugar guidelines refer to added and free sugars, not the natural sugar in whole fruits.

How many apples can I eat per day?

For most healthy adults, 1-3 apples per day is perfectly reasonable, adding 95-285 calories to your diet. There is no medical reason to limit apple intake for healthy individuals. The main consideration is that eating 3+ apples daily provides substantial fiber (13g+), which can cause digestive discomfort in some people if they are not used to high-fiber diets. Increase gradually.

Which apple has the fewest calories?

Granny Smith apples are the lowest-calorie common variety at about 80 calories per medium apple, due to their lower sugar content. McIntosh apples are also on the lower end at about 88 calories. However, the difference between the lowest and highest calorie varieties is only about 20 calories, making variety choice a matter of taste preference rather than a meaningful dietary decision.

Are apple skins safe to eat?

Yes. Apple skins are safe and nutritious. They contain most of the apple's fiber, vitamin A, and antioxidants. Concerns about pesticide residue can be addressed by washing apples under running water (which removes most surface residue) or buying organic. The nutritional benefits of eating the skin far outweigh any residual pesticide concerns for most people.

How long do apples last?

At room temperature, apples last about 5-7 days. In the refrigerator, they last 4-6 weeks. For the longest storage, keep apples in the crisper drawer of your refrigerator, away from strong-smelling foods (apples absorb odors). This long shelf life makes apples ideal for weekly meal prep — buy a bag at the beginning of the month and they will last.

Is apple juice as healthy as a whole apple?

No. A cup of apple juice has 114 calories, 0.5g of fiber, and 24g of sugar. A whole apple has 95 calories, 4.4g of fiber, and 19g of sugar. The fiber in whole apples slows sugar absorption, creates fullness, and feeds gut bacteria. Apple juice removes the fiber and concentrates the sugar, making it more similar to soda nutritionally than to whole fruit. If you drink apple juice, treat it as a beverage to moderate rather than a fruit serving.

How many calories are in an apple with peanut butter?

A medium apple with 2 tablespoons of peanut butter has approximately 283 calories: 95 from the apple and 188 from the peanut butter. With 1 tablespoon of peanut butter, it drops to about 189 calories. This is a balanced snack with fiber (6.4g), protein (4-8g), and healthy fats that keeps you satisfied for 2-3 hours.

The Bottom Line

At 95 calories per medium apple, with 4.4g of fiber and high water content, apples are one of the most satisfying and practical snack foods available. The calorie count barely changes between varieties (80-100 per medium apple), and eating the skin provides the best nutritional return. For tracking your apple and snack intake as part of a complete daily meal plan, an app like Mealift can help you see how an apple snack fits into your daily calorie and fiber targets alongside the rest of your meals.
