An interventional study of VLCD and Standard care in Bariatric Surgery Candidate, Very Low Calorie Diet and Weight Loss, sponsored by Aarhus University Hospital. Completed at 1 site in Denmark. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-05-05.
Sponsored by Aarhus University Hospital · Not applicable, Interventional, and Treatment
To investigate use of Very Low Calorie Diet preoperatively to bariatric surgery can optimize weight loss prior to surgery and increase the patients' satisfaction.
In this project the investigators want to develop an effective Very Low Calorie Diet (VLCD) treatment prior to bariatric surgery, which is optimized in relation to the size and speed of the weight loss as well as in terms of satisfaction both for the patients as for the health care professionals. Thus the investigators will randomize 500 patients to either VLCD or standard care prior to bariatric surgery. The investigators aim to optimize preoperative and the operative course for patients, who are offered bariatric surgery.
