Choose Wet Snacks
Foods rich in water tend to pack fewer calories into bigger servings and come with added fiber. Think cucumbers, apples, bell peppers, celery or, to go really wet, broth-based (not cream, mind you) soups. These are known as nutrient dense because the ratio of nutrients to calories is high. Dry snacks, like granola bars, tend to be calorie dense and a snack of just carbs will generally end up making you hungry soon after.
