How Many Calories Are in an Apple? Nutrition, Types, Portions & Diet Impact

Apples are one of the most commonly eaten fruits in the world—and one of the most misunderstood when it comes to calories. Some people believe apples are “negative-calorie foods,” while others avoid them because of their natural sugar content. If you’ve ever wondered how many calories are in an apple, the real answer depends on size, variety, and how it’s prepared.

This in-depth guide goes far beyond the usual “95 calories” answer. You’ll learn exactly how apple calories vary, why apples are filling despite being low in calories, and how to enjoy them in a healthy, balanced way.

Quick Answer: Calories in One Apple

A medium apple (about 182 grams) contains approximately 95 calories.

But apples come in many sizes and types, which means calorie counts can vary more than most people realize.

Calories in Apples by Size & Weight

Apple Size Weight (Approx.) Calories
Small 149 g ~77 calories
Medium 182 g ~95 calories
Large 223 g ~116 calories
Per 100 g — ~52 calories

Why this matters: Most people underestimate apple size. A large apple can contain nearly 40 more calories than a small one.

Calories in Apples by Variety

Different apple varieties vary slightly in calories due to sugar content and density.

Apple Variety Calories (per medium apple)
Granny Smith ~80–85
Gala ~90–95
Red Delicious ~95
Fuji ~100–105
Honeycrisp ~95–100

Key insight: Sweeter apples tend to have slightly more calories, but the difference is modest.

Calories in Apples by Form & Preparation

Preparation dramatically changes calorie density.

Apple Form Serving Size Calories
Raw apple 1 medium ~95
Apple slices 1 cup ~65
Applesauce (unsweetened) ½ cup ~50
Applesauce (sweetened) ½ cup 90–110
Dried apples ½ cup 120–140
Apple juice 1 cup ~115
Baked apple (plain) 1 medium ~100

Whole apples are the lowest-calorie, most filling option.

Nutritional Profile of an Apple

Apples are not just about calories—they’re nutrient-dense for their size.

Key Nutrients in One Medium Apple:

  • Carbohydrates: ~25 g

  • Fiber: ~4 g

  • Natural sugars: ~19 g

  • Vitamin C: ~14% DV

  • Potassium: ~6% DV

Why Apples Are Low in Calories but Filling

Apples are considered a high-volume, low-calorie food due to:

  • High water content (~85%)

  • Soluble fiber (pectin)

  • Low energy density

This combination slows digestion, increases fullness, and helps control appetite.

Apple Calories and Blood Sugar

Apples have a moderate glycemic index but a low glycemic load, meaning they don’t spike blood sugar quickly.

Tips for Blood Sugar Control:

  • Eat apples whole, not juiced

  • Pair apples with protein or fat (e.g., nuts)

  • Avoid sweetened apple products

Apples can be a good fruit choice for people managing blood sugar when eaten mindfully.

Are Apples Good for Weight Loss?

Yes—when eaten whole and in reasonable portions.

Why Apples Support Weight Loss:

  • Low calories per bite

  • High satiety

  • Easy snack replacement

Example:
A medium apple (~95 calories) vs a granola bar (~180–220 calories).
