Health Education,Volume 117, Issue 1, Page 39-52, January 2017. Purpose The purpose of this paper is to evaluate an online “teachable moment” intervention to promote healthy eating for overweight and food intolerance symptoms. Design/methodology/approach The study involves a 2×2 factorial design with two conditions: group (weight loss vs food intolerance) and condition (intervention vs control). The intervention aimed to generate a “teachable moment” by providing knowledge regarding the relationship between food and the problem (overweight or food intolerance), focussing on the negative aspects of the problem, creating a behavioural model, and encouraging hope and reinvention. Participants receiving the intervention (n=22) completed measures of dietary behaviour and either weight or food intolerance symptoms before receiving the intervention and again one month later. Control participants (n=20) provided measures but did not receive the intervention. Findings There were no significant reductions in weight or food intolerance symptoms. However, compared to control participants, participants in the intervention conditions reported greater intentions to eat healthily (p=0.01) and improved healthy eating behaviour over time, following both an intention-to-treat (p=0.046) and explanatory analys is (p=0.042). Practical implications Encouraging individuals to perceive their everyday situation as a time for change and adopt healthier behaviour early on, may prevent futur...
