Brief Summary

Pre-operative weight loss can reduce the risk intra- and post-operative complications but no optimal pre-operative weight loss strategy has been investigated. Very-low-calorie diets (VLCDs) were proven to results in higher metabolic improvements in the short-term than balanced, hypocaloric diets. Therefore, the aim of the study is to investigate whether a VLCD results in lower intra-and post-operative complications compared to a hypocaloric diet. However, to achieve a optimal compliance in patients having experienced multiple dietary intervention failures, administration of the intervention will be performed by the enteral route using a naso-gastric feeding tube.

Study Arms (2)

Very low-calorie protein-based diet

EXPERIMENTAL

Patients will receive a homemade very low-calorie (\~5 kcal/kg of ideal body weight /day) protein-based formula (milk proteins; 1.2 g per kilogram of ideal body weight) for 4 weeks by a polyurethane nasogastric feeding tube.

Other: Very low-calorie protein-based diet

Hypocaloric diet

ACTIVE COMPARATOR

Patients will receive a commercial balanced enteral formula (\~20 kcal/kg of ideal body weight /day; protein content, 1.0 g per kilogram of ideal body weight) for 4 weeks by a polyurethane nasogastric feeding tube.

Other: Hypocaloric diet

Interventions

Patients will receive a homemade very low-calorie (\~5 kcal/kg of ideal body weight /day) protein-based formula (milk proteins; 1.2 g per kilogram of ideal body weight) for 4 weeks by a polyurethane nasogastric feeding tube.
