Impact of Preoperative Hypocaloric Hyperproteinic Lipid Restricting Diet on Bariatric Surgery

Obesity is one of the greatest pandemics of the 21st century with 30 million new cases each year. In France each year, 60,000 bariatric surgery procedures are performed.

Many preoperative diets have been proposed in the literature with some studies giving positive results. But these diets are often strict and can have adverse effects on metabolism. Very few studies have described the PSMF diet. The hypothesis would be that this diet is associated with a reduction in liver volume with a reduction in steatosis.
