The Pistachio Principle

According to James Painter, PhD, RD, Chair of the School of Family and Consumer Sciences at Eastern Illinois University in the United States, the “Pistachio Principle” is caloric reduction without calorie restriction. It is one of the many ways we can alter our environmental cues, allowing us to become more mindful and satisfied with our food choices. He completed two studies that found that individuals could reduce their overall calorie consumption without consciously restricting their diets.
