Nutrition Education in Cardiac Rehabilitation

Coronary heart disease is one of the United Kingdom\'s biggest killers. In the UK alone 175,000 myocardial infarctions are recorded annually. To lower the financial burden on the National Health Service, cardiac rehabilitation facilitates a systematic and multidisciplinary approach to secondary prevention aimed to improve functional capacity and health-related quality of life, lower rehospitalisation rates and reduce all-cause and cardiovascular mortality with exercise training being the cornerstones. The effectiveness of Cardiac rehabilitation programmes in delivering effective secondary prevention has long been established. Improvements are recorded in cardiovascular endurance, muscular strength and endurance, balance, co-ordination, and quality of life. However, many patients see little or no change in body mass and body mass index, an independent risk factor for coronary heart disease. Interestingly, the inclusion of nutrition education is rarely reported within specific Cardiac rehabilitation settings, therefore evidence of best practice remains elusive and warrants further investigation. The aim of this trial is to compare: * Usual care - Where patients access to two exercise classes per week and all facilities normally available as part of their cardiac rehabilitation programme. Patients in this group will undergo this approach for 12-weeks. * Usual care + Biggest loser - In addition to Usual care, patients in this group took part in the \'Biggest loser\' program in which the patients attended weekly sessions outside of their usual exercise class times. Each session follows a specific theme based on British Heart Foundation healthy eating guidelines. Participants will undergo this approach for 6-weeks and then switch to usual care for 6-weeks. * Usual care + New Education programme. In addition to Usual care, the same weekly topics as the biggest loser are covered yet with bespoke information regarding portion sizes and recipes provided each week and patients given a challenge each week in relation to the topic being covered e.g. include more vegetables. Participants will undergo this approach for 6-weeks and then switch to usual care for 6-weeks. Patients will be tested at baseline, 6-weeks and 12-weeks.
