TPB has guided research aimed at preventing weight regain in overweight individuals who had recently experienced a significant weight loss. McConnon et al. (2012) found that perceived need to control weight predicts the behavior needed for weight maintenance. TPB can also help in assessing the behavioral intentions of practitioners who promote specific health behaviors. Chase et al. (2003) studied dietitians' intentions to promote the consumption of whole grain foods. The study team found that the strongest indicator of dietitians' intentions to promote the consumption of whole grain foods was their normative beliefs about diet. However, some dietitians' knowledge was problematic, with only 60% of dietitians being able to correctly identify a whole grain product from a food label.
