简要总结
Rationale: Sufficient dietary protein intake helps to preserve muscle mass and strength and is a key factor in healthy ageing. Achieving an increased protein intake with regular food products has shown to be a challenge for many older adults. Applying behavioural change techniques may facilitate a more sustained improvement in protein consumption over time.
Objective: To investigate whether a nutritional app intervention can increase the protein intake (with the goal of 1.2 g/kg body weight/day) of older adults, using readily available food products. Secondary and tertiary objective include the effects of the intervention on body composition and muscle strength and long-term effects on protein intake.

盲法说明
Participants in the exercise (active comparator) group are blinded to the real purpose of the study being 'to improve protein intake' to limit subjects bias. Meaning that the participants in the exercise group will also change their diet including their protein intake.

研究组 & 干预措施
Protein and exercise
Only the intervention group is coached to sustainable changes in (1) the amount of protein intake (goal: 1.2 g/kg body weight/d) and (2) the efficiency of protein intake with a focus on high-quality proteins, variety in protein sources, and timing of intake. To increase applicability in daily life, we aim to achieve these goals using readily available protein products. Participants in both groups have access to the application that contains a wide range of muscle and bone-strengthening activities, as well as balance exercises that can be performed independently at home.
干预措施: Nutritional coaching via an app (Behavioral)
