Granola is full of oats, nuts, and seeds. These ingredients all have fiber and protein, which is satiating. In addition, granola requires chewing, which may be another satiety signal that can lead to feeling full. According to nutritionist Richard Mattes, nuts help with weight loss because they're "high in protein, and protein is satiating...high in fiber, and fiber is satiating...rich in unsaturated fats, and there is some literature that suggests that has satiety value."
