[Significance of intentional weight loss on health].
The aim of the present study was critically to review how intentional weight loss in overweight and obesity influences mortality. No randomized weight loss intervention trial has included mortality as an end-point. However, even minor weight loss causes beneficial changes in risk factors for cardiovascular disease, whereas the vast majority of observational studies have linked weight loss to excess mortality. Most observational studies do not have information on intentionality of weight loss and suffer from other methodological limitations making inferences from these studies difficult. Given the available observational evidence, the possibility that intended weight loss may cause some increased mortality cannot be excluded. However, considering the totality of the evidence on effects of intended weight loss among overweight and obese subjects, there may be other benefits, such as: psycho-social and physical well-being, risk factor improvement, decreased morbidity, and in certain high-risk subgroups decreased mortality. Treatment of obesity is therefore recommended, particularly in the presence of risk factors or complications.
