Investigating the Effects of Diets With Different Types of Food Processing Following UK dietAry Guidance on healTh outcomEs: an 8-week Community-based Crossover Randomised Controlled Trial in People With Overweight or Obesity, Followed by a 6-month Behavioural Intervention
In Brief
A clinical study evaluating Healthy, balanced Diet A, Healthy, balanced Diet B, and 1 other intervention for Obesity and 2 related conditions. Completed, enrolled 55 participants across 1 site.
Detailed Summary
There are two parts to this study: 1. The investigators will study if the benefit from eating a healthy, balanced diet depends on the types of food processing in the diet. The investigators will do this by providing participants with two diets that follow the Eatwell Guide (referred to in this study as Diet A and Diet B to avoid unblinding), but containing foods with different types of food processing, for 8 weeks each. The investigators will collect data on blood pressure, body composition, physical activity and fitness, questions regarding quality of life, mental health and wellbeing, and blood samples at the start of each diet and at 4 and 8 weeks into each diet. 2. The investigators will then study whether participants are able to switch from their usual unhealthy diet to a healthy, balanced diet, and the benefits of doing so. The investigators will do this by providing participants with 6 months of personal support. The investigators will also look at what helps participants to maintain a healthy diet, and what makes it difficult. The investigators will also support participants to be more physically active.
