How Many Calories Are There In A Granny Smith Apple? | Quick Facts Guide

Calories In A Granny Smith (By Size And Weight)

A green Granny Smith is lean on energy and big on crunch. Calorie counts scale with weight. The table below shows typical ranges with skin on. Numbers come from widely used nutrition datasets built on raw apples with peel.

Size / Description	Edible Weight	Calories
Per 100 g (with skin)	100 g	~52 kcal
Small whole (snack)	150 g	~78 kcal
Medium whole (common)	182 g	~95 kcal
Large whole (baking)	223 g	~116 kcal
1 cup slices	110 g	~57 kcal
1 medium, peeled	~170 g	~88 kcal

Why these numbers? A medium apple typically weighs about 182 g, which lands near 95 calories when raw and unpeeled. Per-100-gram values sit close to 52 calories, so you can scale up or down by weight. That’s handy when you cook, slice, or share.

What Changes The Calorie Count?

Weight And Water

These apples contain a lot of water. More grams on the scale mean more energy overall, but the energy per gram stays low. That’s why a bigger fruit bumps the total, yet still feels light.

Peel On Or Off

The peel holds extra fiber and tiny amounts of fat-soluble compounds. Peel removal trims a touch of fiber and can shave a few grams of weight. The energy difference per fruit is small, but the fiber change matters for fullness.

Raw, Baked, Or Sauced

Raw slices mirror the whole fruit numbers when you weigh them. Baking removes water, so each bite packs slightly more energy per gram. Unsweetened applesauce tracks the raw fruit closely by weight, while sweetened versions jump because of added sugar.

Granny Smith Nutrition Snapshot

A medium green apple brings carbs for quick energy, minimal fat, and a small amount of protein. The peel boosts fiber, which helps with fullness and steady digestion. Guidance from the Harvard fiber page outlines how fiber supports appetite control. You’ll also pick up vitamin C and a mix of polyphenols that live mostly in the skin.

Carbs And Natural Sugar

Most of the energy comes from carbohydrates. In one everyday fruit, you’ll see roughly 25 g of total carbs with a big share as natural sugars. Because the water content is high, the calorie density stays low, so volume works in your favor.

Fiber In The Peel

Keep the peel on to get more roughage per bite. That peel carries both soluble and insoluble types, which helps with regularity and makes a snack feel more filling.

How To Weigh Or Estimate Your Apple

Kitchen scales make this easy. No scale? Use size cues. A medium fruit is about 3 inches across. Large fruit edges past that. If you’re cooking, weigh the trimmed pieces to match recipe targets.

Quick Math You Can Use

Use the 52-calories-per-100-grams rule. If your apple weighs 160 g, that’s roughly 0.16 kg × 520 kcal/kg ≈ 83 calories. If you share half of a 182 g fruit, you’re close to 46–48 calories.

Smart Ways To Eat A Tart Green Apple

Solo Snack

Grab one as a stand-alone snack when you want crunch for not many calories. The crisp bite pairs well with a glass of water for a bigger sense of fullness.

Protein Pairings

Match slices with peanut butter, Greek yogurt, or cheddar. The combo balances carbs with fat and protein, which steadies hunger across the next few hours.

Salads And Slaws

Thin slivers add pop to greens, grain bowls, and cabbage mixes. The tart edge balances richer dressings and roasted add-ins.

How This Fits A Daily Budget

A green apple slides into nearly any calorie plan. Snacks fit better once you set your daily calorie needs. One medium fruit near 95 calories is an easy swap for higher-energy sweets.

Evidence And Sources Worth Knowing

Nutrition figures for raw apples with skin come from widely referenced datasets. The searchable database at USDA FoodData Central lists per-100-gram values near 52 calories for raw apples with peel. An independent overview from the Harvard Nutrition Source outlines typical numbers for a medium fruit and gives extra context on phytonutrients. These pages keep details specific and avoid guesswork.

Comparing Apple Types (Per 100 g)

Different varieties land in a similar calorie range. Sugar and flavor shift more than energy does. Here’s a simple side-by-side so you can pick by taste without losing track of numbers.

Variety	Calories (100 g)	Sugars (100 g)
Granny Smith	~52 kcal	~10 g
Red Delicious	~52 kcal	~11 g
Fuji	~57 kcal	~13 g

Cooking Notes For Bakers And Meal Preppers

Pies And Crisps

This variety holds shape, so slices don’t turn mushy. Recipes with butter, sugar, and crust raise the final energy far beyond the fruit. If you want a lighter pan, use a thinner top, cut sugar, and add warm spices for flavor.

Roasted Slices

Roasting drives off water and concentrates sugars. Weight your tray before and after to keep estimates tight. If 500 g of raw slices cooks down to 400 g, that tray will carry about 208 calories from the fruit alone (0.4 kg × 520 kcal/kg).

Applesauce Choices

Unsweetened sauce stays close to the raw fruit numbers per gram. Sweetened jars add extra sugar, so check labels when you move from whole fruit to spoonable batches.

Portion Pointers For Different Goals

Weight Management

Low energy density makes this a tidy snack between meals. Pair with protein for stronger satiety. Slice slowly and chew well to extend the eating window.

Blood Sugar Balance

Whole fruit packs fiber and water, which slows digestion compared with juice. Spread fruit intake across the day and keep the peel on for better texture and steadier absorption.

Kids And Lunchboxes

Small fruits land near 70–80 calories. Cut wedges around the core and give a quick dip in lemon water to keep color bright.

Simple QA: “Is Green Always Lower In Sugar?”

Not always. Tart taste doesn’t guarantee fewer sugars per gram than a red variety. The difference across common apples is small. Pick the one you enjoy; portions and add-ins matter more.

Label Literacy: When Your Apple Comes Packaged

Bagged slices and store-made cups should list grams and calories per serving. Use the serving gram weight to map back to the 52-kcal-per-100-g rule. If a cup says 110 g, you can spot that the fruit portion is roughly 57 calories before dips or toppings.

Storing And Prepping For Best Bite

Storage

Keep them chilled for longer crunch. The crisper drawer slows softening. Don’t stack heavy items on top; bruises shorten shelf life and dull the texture.

Prep

Rinse under running water, dry, and slice right before eating. If you prep in advance, lemon juice or a splash of orange juice helps cut browning. A sharp knife gives clean edges and less juice loss.
