For many popular diets there is no evidence to support the claims made or the mechanisms by which weight is lost. <br>All diets that create an energy deficit will result in weight loss. <br>For weight loss there is no one specific formula in terms of diet composition that is optimal for all overweight or obese persons. Genetics and clinical, psychosocial and environmental factors may have an impact on outcomes. <br>Diet composition does, however, influence metabolic outcomes and at 1 year most overall improvements in cardiac risk factors are seen on the lower-fat diets. <br>Dietary adherence is a key determinant of long-term weight loss and therefore the prescribed diet should take into account practical issues such as the effort and flexibility in planning meals, personal lifestyle, tastes and preferences. <br>Generally the more limited the food options, the greater the risk for nutrient deficiencies.
