A new approach to obesity treatment (according to The Lancet – Diabetes Endocrine Branch) Obesity treatment is a complex medical problem. Previously, the main emphasis was on lifestyle changes, such as diet control and increased exercise. However, this alone is still not ideal for long-term weight control. Nowadays, it is advocated that, depending on individual characteristics, one can choose to take weight loss pills, or bariatric surgery (which may be the main long-term effective means), or implantation of an abdominal vagus nerve block device (adopted by the US Figure Food and Drug Administration).
