Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Both the omega-3 fatty acid doses and the CBT will begin on Day 1 of the treatment phase. Baseline assessments will have occurred 1 week prior to the start of the treatment phase.
Group 2: 3g/day of Omega-3 fatty acids
Group 3: 12 week Cognitive Behavioural Therapy (CBT) Healthy eating and exercise education, 3g/day of Omega-3 fatty acids
Omega-3 fatty acid intervention includes a dose of 5 oral capsules daily. The dose will contain a total of 1.75g of eicosapentanoic acid (EPA) and 1.25g of docosahexanoic acid (DHA). The placebo dose will be 5 oral capsules that contain vegetable oil. Doses will continue daily for 6 months.
The CBT healthy eating and exercise intervention will consist of weekly sessions (duration: 1-1:15hrs/session) for 6 weeks, with fortnightly sessions for the 2nd 6 weeks. I.e. 9 sessions in total. Sessions will be delivered face-to-face by an accredited dietitian and exercise physiologist. General topics will cover healthy eating, goal setting, exercise and fitness. Each session will also include a group fitness that comprises 30 minutes of the session. The type of exercise will be a low intensity warm up and then resistance training using elastic resistance bands. Stretching will occur each session. Time is also taken to educate participants to progress their exercise program at home. Exercises at home may include walking, cycling, running, swimming or other modalities depending on each participants preference.

Outcomes
Primary outcome [1] 259185 0
Changes in body composition- lean body mass and fat mass. Body composition will be measured primarily by air displacement plethysmography (ADP), the specific brand of the equipment is called the, BodPod. Additional measures will be a waist and hip circumference via tape measure, and bio-electrical impedance to determine lymphoedema status. Trained Dietitians will take all measurements.
