Social Cognitive Theory (SCT) has been used to explain findings derived from focus group discussions (N=4) held in the UK with the aim of informing best practice in personalised nutrition. Positive expectancies included weight loss and negative expectancies surrounded on-line security. Monitoring and feedback was crucial to goal setting and progress. Coaching by the service provider, family and friends was deemed important for self-efficacy. Paying symbolised commitment to behaviour change. The social context of eating, however, was perceived a problem and should be considered when designing personalised diets. SCT could provide an effective framework through which to deliver personalised nutrition.
