Study summary

Critically ill patients with body mass index (BMI) inferior to 20 kg/m2 have worse outcomes compared to normal and overweight patients. The impact nutrition therapy in this population is not yet stablished. There is a concern that too low caloric intake might worse their malnutrition; on the other hand, overfeeding is always a risk with serious consequences.

The hypothesis of this study is that nutritional support, especially caloric and protein intake, can influence the outcome of underweight critically ill patients.
