Design outcomes
Primary
| Measure | Time frame |
|---|---|
| ß-hydroxybutyrate (ßHB; tmax) in venous blood, measured before the intervention (t0) and at 30, 60, 120, 180, 240 and 300 minutes (t1–t6) after the intervention. Blood samples are taken via an indwelling venous catheter. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Body weight measured on scales prior to the intervention days - Height measured using a stadiometer prior to the intervention days - Body Mass Index (BMI) calculated from body weight and height prior to the intervention days - Body composition measured using bioelectrical impedance analysis (BIA) prior to the intervention days - Insulin, glucose and essential/non-essential fatty acids in venous blood, measured before the intervention (t0) and at 30, 60, 120, 180, 240 and 300 minutes (t1–t6) after the intervention - Ketone bodies in interstitial fluid via a continuous ketone body sensor, continuous measurement - Glucose in interstitial fluid via a continuous glucose sensor, continuous measurement - Acetone in exhaled air, measured before the intervention (t0) and at 30, 60, 120, 180, 240 and 300 minutes (t1–t6) after the intervention - Glucose and ßHB in capillary blood, measured before the intervention (t0) and at 30, 60, 180 and 300 minutes (t0, t1, t2, t4, t6) after the intervention - Ketone bodies, leukocytes, nitrite, pH, protein, glucose, urobilinogen, bilirubin, and blood in urine via collection of spontaneous urine and analysis with urine test strips between t0 and t6 - Resting energy expenditure (REE) and macronutrient contributions to energy metabolism via indirect calorimetry before the intervention days and up to twice per intervention day - Stool consistency according to the Bristol Stool Chart: assessed once to determine the usual stool consistency prior to the first intervention, and retrospectively for the first bowel movement following each intervention | — |
