A medium apple (about 182 g) provides roughly 95 calories, 25 g of carbohydrate, and 4 g of fiber, per USDA FoodData Central. Apples are about 85% water and high in fiber, which helps them satisfy hunger for few calories — a useful swap for energy-dense snacks. Eat the skin for the most fiber and polyphenols. Pair with a protein or fat source if you want longer-lasting fullness.
