The obesity epidemic is steadily increasing worldwide, and high body mass index (BMI) is a major risk factor for cardiovascular diseases, diabetes, hypertension, musculoskeletal disorders, and also some cancers [1].

There is a strong interest in finding less invasive methods [4] and whether that preoperative weight loss improves surgery outcomes [2] and reduces perioperative complications [5].
