Primary

Measure	Time frame
1. Dietary intake: Assessment of habitual dietary intake was done by means of an 180-item semi-quantitative FFQ and up to nine repeated 24-hour recalls. All measurements were repeated at one and two years of follow-up. 2. Eating behaviour was assessed by means of the Dutch Eating Behaviour Questionnaire (DEBQ). Additionally, eating behaviour was assessed by a questionnaire developed by research institute Wageningen Economic Research (WECR). The Food Choice Questionnaire (FCQ) was used to assess factors related to food choice. Food neophobia was scored using the Food Neophobia Scale. Eating Rate was assessed according to one of five rating categories. Determinants of intake of fruit vegetables and snacks was examined by means of a questionnaire as developed by Hooft van Huysduynen and colleagues (2014) based on determinants from the Theory of Planned Behaviour. All measurements were repeated at one and two years of follow-up. 3. Nutritional recovery biomarkers: Total 24-hour urinary nitrogen excretion was determined at the Division of Human Nutrition by the Kjeldahl technique 19 (Foss KjeltecTM 2300 analyzer). Urinary sodium and potassium concentrations were measured with an ion-selective electrode on a Roche 917 analyser (Indianapolis, USA). Urinary creatinine concentrations were measured at 520 nm on the Synchron LX20 by the modified Jaffé procedure using a commercial kit. Total 24-hour sodium and potassium excretion were calculated by multiplying total weight of collected urine by sodium or potassium concentration. Additionally, this was divided by 0.86 for sodium and by 0.81 for potassium, assuming that this percentage of intake is excreted in the urine. Urinary protein was calculated with the following formula: 6.25 * (urinary N / 0.81) accounting for faecal and skin losses (approximately 19%). All measurements were repeated at one and two years of follow-up 4. Anthropometrics: Height was measured with a stadiometer (SECA, Germany) to the nearest 0.1 cm. Weight	—
