[36] is a pilot study in mechanically ventilated patients (n = 112) employing a bundle comprising supervised nutrition intervention including indirect calorimetry, as compared to a body weight guided protocol. The indirect calorimetry group received a higher intake of calories and protein, demonstrating the feasibility of indirect calorimetry. The fact that higher intake was also associated with a longer ICU stay is in total accord with the abovementioned EPaNIC study. As pointed out in an accompanying editorial, the use of indirect calorimetry should be recommended to individualise nutrition, extending follow-up beyond the doors of the hospital [37] .
