Study explains improved outcomes with gene-specific diets
The Theory of Planned Behaviour provides an explanation as to why genetic-based lifestyle interventions create better behaviour change than population based interventions.
Behaviour change theories can help provide systematic explanations for why certain interventions promote changes in lifestyle habits. The Theory of Planned Behaviour (TPB) is one of the most widely accepted behavioural theories and suggests that a person's likelihood of carrying out a planned behaviour is influenced by: attitudes, about the likely consequences of a given behaviour; subjective norms, relating to beliefs about the expectations of others; and perceived behavioural control, relating to the perception of factors that may assist or impede certain behaviours.
