Abstract

This research project attempted to assess and describe the food portion size estimation abilities of 30 obese adults participating in weight control efforts. Food records, which include entries of food items and the amount portioned, are tools commonly used in nutrition research and therapy. Little research has been done on portion size estimation accuracy. The ability to do so could be of importance in the clients overall effort to successfully lose weight and maintain their new weight.

Results of analysis of statistical data showed that subjects used measuring devices to aid in portioning less than one-fourth of the time. They rated their confidence in ability to estimate correctly as moderate at 2.96 out of a possible 5. The portions of two foods ( corn and carrots) were significantly underestimated (p < .05). A 3-ounce boneless breast of chicken, 3/4 cup bran flakes, and 1 teaspoon margarine were estimated accurately. Care should be used by nutritionists when making assessments and recommendations based on self-reported food intake data.
