"You'd want healthy fats to account for about 80% of your calories, and protein around 20%," Dr. Eric Westman, director of the Lifestyle Medicine Clinic at Duke University, told TIME.
By comparison, the average American gets roughly 50% of their calories from carbs, 15% from protein, and 30% from fat, according to the Centers for Disease Control and Prevention (CDC).
Foods like avocado, butter, coconut oil, eggs, and fish high in omega-3 fats, such as salmon, albacore tuna, and sardines, are bountiful sources of healthy fats.
