Yes. Whole apples can support weight management as part of an overall calorie-controlled diet, mainly because they are relatively low in calories and provide filling fiber and water. A medium apple has about 95 calories and roughly 3–4 grams of fiber, which can slow digestion and help you feel fuller after a snack.
Large long-term observational research has linked higher intake of fiber-rich, low-glycemic fruits such as apples and pears with less weight gain over time. They are a useful everyday snack choice, not a stand-alone weight-loss treatment, and whole fruit is generally preferable to juice for satiety and fiber.
