Overweight and obesity are common health risks, but it can be difficult to effect weight change. This randomized controlled trial examined the effects of a novel Cookery skills intervention on body mass index (BMI) in overweight and obese patients with cardiovascular disease, who had previously attended a cardiac rehabilitation programme. Patients with BMI >27 kg/m(2) were randomized to either a 5-week cookery skills course with written educational materials, or to written materials only. Questionnaires on lifestyle risk factors and food frequencies were administered at baseline, 6 and 24 months. The primary outcome in an intention-to-treat analysis was a change in BMI at 6 months. Secondary outcome was a change in BMI at 24 months. Changes in macronutrient consumption were examined in both analysis of covariance and repeated measures ANOVA models. Of the 172 patients, 116 (67.4%) patients consented to participate in the study. The intervention was found to be well accepted and attended by the patients (70.5% of patients in the intervention group attended the sessions). Whilst both intervention and control groups were noted to have a small reduction in BMI, there was no significant difference between the groups. There was no significant group effect noted for any change in macronutrient consumption at 6- or 24-month follow-up. This pilot study of a novel cookery skills project was well accepted amongst this population. Although the majority of participants had a net loss in BMI, the cookery skills intervention was not associated with any change in BMI beyond that achieved by written information alone.
