Effects of the EatWelLog App on Enhancing Diet Management for Older Adults With Sarcopenic Obesity
Sponsor: The Hong Kong Polytechnic University
Summary
Background: Sarcopenic obesity (SO) affects 10% of older adults increased to 23% of those 75+, raising health risks and health cost. Objectives: We will evaluate the effects of the EatWelLog App-based intervention on SO status (primary outcome), and nutritional and exercise parameters (secondary outcomes) by enhancing self-management and sustaining diet adherence among the m-Health group using the App versus the control group. Following verification of the intervention's effectiveness, we will analyse its cost-effectiveness. Design and subjects: Randomized controlled trial with 212 older people with SO. Interventions: The m-Health group will receive an 8-week supervised nutrition and exercise programme, incorporating the EatWelLog App for dietary management during and after the supervised programme. The control group will receive the same programme without the App. Main outcome measures and analysis: The primary outcome is SO status evaluated using handgrip strength, muscle mass, body fat mass, and physical performance. Secondary outcomes include nutritional status, quality of life and exercise adherence. The App intervention's costeffectiveness will be analysed. Expected results: The m-Health group should demonstrate greater, more sustained improvements in SO and secondary outcomes compared to the control group at Week 8, and at the 3-, 6-, 9-, and 12-month follow-ups. Clinical significance: The EatWelLog App could provide customized support, enhance dietary adherence, and improve long-term outcomes, offering a novel, economical approach to SO management.

Dietary Modification programme
• This programme aims to improve the participants' self-efficacy in adopting our previously validated diet regimen\*. It includes 3 personalized, one-hour, face-to-face sessions in weeks 1, 3 and 7 conducted by a dietitian plus 5 dietary related health talks in the remaining weeks (i.e. Week 2, 4-6, 8) * Dietary Regimen: a moderate hypocaloric diet reduces daily energy intake by 12% for steady weight loss while preserving muscle mass9. To address the reduced anabolic response in older people, a protein intake of 1.5 g/kg of body weight per day is recommended, with leucine-rich animal proteins prioritized to enhance muscle development9
Exercise Training
Participants will receive an 8-week exercise training during the programme. The training combines resistance and aerobic exercises to increase muscle mass and strength while reducing fat in individual with SO. Participants will receive a YouTube link and pamphlet detailing exercises to follow 30 minutes daily, five times a week, during and after the programme.
The EatWelLog App
Participants in the M-health group will be instructed to use the EatWelLog App for daily diet self-management. This App supports participants with SO by providing a structured approach to managing a diet that encourages steady weight loss while maintaining muscle mass. Nutritional recommendations will be also be provided according to individuals' demographic information.
