A study reviewed various ways that nuts, including pistachios, may help maintain body weight. A main reason may be that eating nuts makes one feel full, resulting in eating less food at one sitting and being less hungry to eat again. This may be due to the many nutrients, such as fiber, protein and healthy fats, as well as the need to chew, which slows the eating process. In-shell pistachios have the added benefit of slowing eating time. The authors conclude that, even though nuts are calorie-dense, they have other attributes that make them appropriate for weight management.
