Abstract Background: The prevention and treatment of overweight and obesity is a priority for all health professionals and requires resources that are regularly evaluated to ensure that they meet the needs of their target population. Dietitians in Obesity Management UK (DOM UK), a specialist group of the British Dietetic Association, commissioned an evaluation of their resources. These have been developed for use by Dietitians to determine the uptake and implementation of DOM UK resources in dietetic practice, as well as the opinions and suggestions of Dietitians concerning the resource pack. Methods: A random sample of 20% (n = 33) of the 165 Dietitians who had ordered resources were selected from the DOM UK database along with 20% of DOM UK members who had not (n = 38). Data were then collected using telephone-administered questionnaires. Results: Most of the Dietitians who used the resources favoured them because they improved their consultations and were liked by patients. Resources ‘j’ (controlling your portions) and ‘k’ (planning your meals) were most frequently used. However, the cost of the pack was a deterrent to both new and repeat orders. The evaluation also revealed that 17% of DOM UK members were unaware of these resources and 23% who ordered them were unaware that online samples were available. Conclusion: The evaluation showed that most Dietitians who used the resources found them very useful especially resources concerning meal planning and portion sizes. However, concerns about cost and the need for greater awareness about the resources among Dietitians were highlighted.
