Conditions
Brief summary
This study aims to test whether a higher intake of vegetables is more beneficial for weight loss than a lower intake of vegetables. We hypothesise that those in the intervention group will have a better anti-loxidant staus, will lose more weight, show greater improvements in risk factors associated with over weight, will demonstrate greater perceptions of satiety and will report a greater acceptability for vegetable consumption.
Interventions
Isocaloric diet with 5 serves vegetables per day for 12 months. Participants will be advised on a diet plan in terms of the amounts and types of food groups as outlined in the Australian Guide to Healthy Eating. Energy requirements will not be specifically restricted but energy dense nutrient poor foods will be excluded (cakes, biscuits, soft drinks) and this will likely reduce energy intake, that is, the energy value of the trial dietary patterns is likey to be reduced with this dietary advi

Initial dietary counselling sessions one on one with the dietitian will take one hour and follow up sessions at month 1,2,3, 6, 9, 12 will take 30 minutes. Between visits, SMS messages and emails will be sent fortnightly to provde behavioural support.
