Brief summary

Mindless eating or habitual eating has been described as the most plausible factor to explain why we struggle to keep our excess weight off. Once we form a habit, it can be difficult to act in non-habitual ways despite our best intentions. Therefore the primary purpose of this study is to investigate the effectiveness of 2 weight management interventions which focus on habitual behaviour and assess whether we can maintain weight loss for at least 12 months if habits are altered.

Interventions

Intervention 1: '10 Top Tips' aims to increase habitual performance of healthy lifestyle behaviours such as 'Keep a food diary', 'Switch to low fat food', 'Practice portion control' etc. The tips are provided to the participants in the form of a single pamphlet which is provided at baseline. A tracking diary is also provided for record keeping. The intervention period is 12 weeks.

Intervention 1: '10 Top Tips' aims to increase habitual performance of healthy lifestyle behaviours such as 'Keep a food diary', 'Switch to low fat food', 'Practice portion control' etc. The tips are provided to the participants in the form of a single pamphlet which is provided at baseline. A tracking diary is also provided for record keeping. The intervention period is 12 weeks. Intervention 2: 'Do Something Different' aims to break daily habits and increase behavioural flexibility by assigning participants a different task to perform each day. Examples of these tasks include: 'Take a different route to work', 'Write a short story', 'Wear something you've never worn before' etc. These tasks are emailed or text messaged to the participants depending on their preference. Adherence is not monitored. The intervention period is 9 weeks. No intervention group will receive both interventions. Both interventions explained above will be administered by the principle researcher of this study who is a qualified dietitian.
