Avocados include a sizeable quantity of fiber, a nutrient advantageous to the health of the metabolic system, in addition to being helpful for the reduction of excess body fat. Consuming foods high in fiber can help restrict your appetite, reduce the chance of getting high blood pressure, and bring cholesterol levels down. It can also help lessen the risk of developing high cholesterol. Avocados are permitted on the ketogenic diet despite the high amount of carbohydrates they contain since they speed up metabolism and do not impact the amount of glucose in the blood.
