This project had two parts: a review of how indirect calorimetry (a method to measure energy use) is used in patients with eating disorders, and a study testing its use on hospital wards. Dr Kylie Matthews-Rensch's team trained dietitians to use this device and explored its practical application with patients.

Indirect calorimetry is a precise way to determine nutritional needs but isn't widely used for people with eating disorders. This research aimed to understand how to use it safely and effectively for these patients, considering their unique psychological and physical needs. By learning how to better use this method, we can offer more personalized and accurate nutrition care, potentially improving recovery and reducing hospital stays.

This project improved the knowledge and skills of dietitians in using indirect calorimetry, allowing them to apply it in clinical practice and future research. The findings will help create practical protocols for using this method in a sensitive and patient-centered way. This project shows how indirect calorimetry can enhance personalised nutrition care for people with eating disorders, ultimately improving their treatment and recovery process.
