Summary

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.

Interventions

Type	Name	Description
BEHAVIORAL	Nutritional coaching via an app	Coaching involves e-coaching via an app, supported by one telephone consultation. Within the SO-NUTS (preventing obesity, sarcopenia, and Sarcopenic Obesity in retirement through digital, personalised interventions for healthy NUTrition and physical activity for Seniors) project, BCTs are investigated that fit the older adult population. Insights gained from systematic review and focus group interviews are applied to the Eifit application.
BEHAVIORAL	Exercise recommendations	The objective is to adhere to the 2017 physical activity guidelines as set by the Health Council of the Netherlands i.e. "Engage in at least 150 minutes of moderate-intensity physical activity per week, perform muscle- and bone-strengthening activities at least twice a week in combination with balance exercises, and avoid prolonged periods of sitting." 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. Activities such as walking, cycling, tennis, or swimming can also be added. Participants can monitor their progress themselves, and if desired, push notifications, tips, and reminders can be sent.
