Barbara Rolls (nutritionist)

Barbara Rolls is a respected nutrition researcher and professor known for her work on weight management and healthy eating. She developed the concept of "volumetrics," a way of eating that focuses on consuming low-calorie, high-volume foods—like fruits, vegetables, and soups—to help people feel full and satisfied while reducing overall calorie intake. Her approach emphasizes the importance of nutrient-dense foods to support weight loss and health without feeling deprived. Rolls’ research has influenced dietary recommendations and strategies aimed at promoting sustainable, pleasurable, and effective eating habits.
