Brief summary
The aim of the research is to investigate if the option to choose a particular diet strategy as opposed to being prescribed a set strategy leads to greater weight loss. We hypothesise that freedom to choose the diet strategy will result in greater weight loss. This randomised parallel study and will include both men and women. Participants will be randomised to Choice or No Choice. The No Choice arm will be the 5 & 2 strategy (5 days of habitual eating with 2 very low energy intake days of 2000 - 3000kJ/day) compared with a Choice of 2 & 5 or continuous energy restriction (daily energy restriction between 4000-5000kJ/day). Participants will be asked to follow the diet for 8 weeks and attend the Sansom CTF at the start for randomisation and dietary instruction and every two weeks for 8 weeks. They will have height measured once and weight measured on each occasion. The first visit will take approximately 30 minutes and subsequent visits will take 15 minutes.
Interventions
The intervention group will be allocated to a 'Choice Group' which will give participants the opportunity to choose between either a 5 & 2 dietary strategy (5 days of habitual eating with 2 very low energy intake days of 2000 - 3000kJ/day) or continuous energy restriction dietary strategy (daily energy restriction between 4000-5000kJ/day).

They will have height measured once and weight measured on each occasion. The first visit will take approximately 30 minutes and subsequent visits will take 15 minutes. The intervention will be delivered to participants individually by a research assistant under the supervision of a Dr Keogh who is a qualifeid dietitian. Eduation material with a detailed description of the chosen diet and how to follow it will be provided to the participants. Participants will have weight measured individually every two weeks when they attend the Sansom Clinical Trial Facility. All participants will be asked to keep food diaries for 3 days/week while they are in the study.
