To evaluate two different diets and their effects on weight loss and measurements of several risk factors for cardiovascular disease. One diet will be a high saturated fat diet (HSFD) and the other is a low saturated fat diet (LSFD) that limits fat but especially saturated fat as red meat. All participants in this study must eat both diets as this is a randomised cross-over design.
