Obesity is an 'epidemic' within the UK. Individuals living with obseity are at risk of developing cancer, heart problems and dieing. Furthermore, obesity impacts on psychological wellbeing via lowered self-efficacy, self-esteem, body image and overall quality of life (QoL). A pilot randomised controlled trial (RCT) is proposed to investigate the additional benefit of a psychological intervention alongside treatment as usual (TAU) in a weight management service. Patients routinely attending an outpatient clinic will be randomised into TAU with or without additional acceptance and commitment Therapy (ACT) group based-input and their outcomes monitored over time.

Overweight and obesity is reported as an 'epidemic' problem within the UK as well as the world. Individuals living with this may be at higher risk of developing co-morbidities, such as cancers, heart problems or diabetes, and higher mortality rates are reported in this group. Furthermore, overweight and obesity can also impact on a person's psychological wellbeing, such as their self-efficacy, self-esteem and body image as well as have a negative effect on their overall quality of life (QoL). Therefore, a pilot randomised controlled trial (RCT) is proposed to investigate the additional benefit of a psychological intervention alongside treatment as usual (TAU) in a weight management service. Patients routinely attending an outpatient clinic will be randomised into TAU with or without additional Acceptance and Commitment Therapy (ACT) group based-input.
