Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Every time participants receive diet and lifestyle advice (week 5, 8 and 11), they are asked to formulate implementation intentions describing when and how they plan to implement the received advice. After a three-week period, prior to receiving new advice, participants will be asked to score the degree of compliance with the implementation intention they formulated on a 7-points Likert scale (very low-very high). By monitoring the degree of compliance during the intervention period, both trends within individuals and between groups can be observed. | — |
Secondary
| Measure | Time frame |
|---|---|
| Measures of muscle health status including physical performance, handgrip strength, sedentary behaviour, quality of life, parameters of metabolic health status, protein and lipid profiles in responses to a challenge test, parameters of glycaemic control and patient specific complaints will be measured both at baseline and at the end to identify the degree of variation in this population. | — |
