Design outcomes

Primary

Measure	Time frame
Dietary intake will be assessed by a trained research dietician by three 24h recalls (one in-person and two by telephone) using the multiple pass technique. Mean daily energy intake, protein intake and carbohydrate intake will be calculated using the Dutch Food Composition Database 2011. Depression/anxiety will be assessed using the Hospital anxiety and depression scale (HADS). Amino acid profiling will be done in blood plasma by high performance liquid chromatography (HPLC)/fluorescence. Characteristics of patients, including weight loss, will be obtained from medical records.	—
