How Many Calories in an Apple?

A medium apple weighing around 182 grams contains 95 calories. That makes it one of the lowest-calorie fruits you can eat relative to how filling it is. The high water content (about 86%) and 4.4 grams of dietary fiber mean an apple keeps you satisfied far longer than most 95-calorie snacks.

Apples are one of the most widely consumed fruits on the planet, and for good reason. They require no prep, they travel well, they last weeks in the fridge, and their nutritional profile punches well above their calorie count.

🍎 Calories by Apple Variety

Sweeter varieties tend to have slightly more sugar and therefore more calories. Tart apples sit at the lower end.

🍏 How Many Calories in a Green Apple?

A medium Granny Smith (the most common green apple) has about 80 calories, roughly 15% fewer than a sweet Fuji or Gala. Green apples also tend to have less sugar and slightly more fiber, which is why some people on low-carb diets prefer them.

⚖️ Are Apples Good for Weight Loss?

Apples rank among the most effective fruits for weight management. The combination of high water content, substantial fiber and low calorie density means you get a lot of volume for very few calories. Research published in the journal Appetite found that eating an apple before a meal reduced total calorie intake by about 15% compared to skipping the fruit.

The pectin fiber also slows digestion and helps regulate blood sugar, which reduces the energy crashes and cravings that lead to overeating. One apple provides 18% of your daily fiber for just 95 calories.

🧠 Do You Need to Eat the Skin?

Most of the fiber and nearly all the antioxidants in an apple are concentrated in or just below the skin. Peeling an apple removes about a third of the fiber and up to 70% of the polyphenols. If you can stomach the texture, eating the skin is worth it nutritionally. Just give it a good wash first.

🍎 An Apple a Day: What the Science Actually Says

A 2015 study in JAMA Internal Medicine tested the old saying literally. Researchers compared daily apple eaters to non-apple eaters across 8,000+ adults and found that apple eaters had fewer prescription medication visits but no statistically significant difference in doctor visits overall. The saying is roughly half right, which in nutrition science is actually not bad.
