Colles et al. 2006. Preoperative weight loss with a very-low-energy diet: quantitation of changes in liver and abdominal fat by serial imaging
A very low energy diet (VLED) can result in substantial, rapid weight loss and is increasingly prescribed before obesity surgery to minimise risk and difficulty by reducing liver size and abdominal adiposity. This observational study demonstrates the efficacy of using a VLED pre-bariatric surgery for 2-6 weeks.
