Objective: The primary purpose of this study was to compare obese versus nonobese adults and weight cyclers versus maintainers on measures of dietary helplessness, nutrition concern, dietary restraint, and disinhibition. Method: Dietary helplessness, nutrition concern, dietary restraint, and disinhibition were assessed in 385 healthy obese and nonobese men and women in the RENO Diet‐Heart Study, a 5‐year prospective investigation of cardiovascular risk factors, weight cycling, and lifestyle. Results: The results indicated that dietary helplessness and disinhibition were significantly greater in obese individuals, subjects with a history of weight cycling, and weight fluctuators (prospectively measured). Women were found to score significantly higher than men on measures of dietary helplessness, disinhibition, and cognitive restraint. Discussion: The role of nutrition attitudes is discussed in relation to dietary self‐regulation, weight fluctuation, and management of body weight. © 1995 by John Wiley & Sons, Inc.
