Personalized Nutrition Coaching for a Weight Loss Program Among Overweight and Obese Nurses

Obesity among healthcare workers has become an increasing public health concern, with potential consequences for work productivity, quality of care, and long-term health outcomes. Despite their role in promoting health, healthcare workers often face demanding schedules, high stress levels, and limited access to structured health promotion programs, placing them at elevated risk for overweight and obesity. In the absence of targeted workplace interventions, these conditions may persist and worsen over time, highlighting the need for effective, sustainable, and context-specific strategies to support healthier lifestyles among healthcare workers.

This study aims to assess the effectiveness of personalized nutrition coaching as part of a weight loss program for Nurses in Indonesian Hospital. Participants who receive the intervention are expected to demonstrate improvements in nutritional status, including weight-related outcomes, reduction in body fat percentage, reduction in waist circumference. The intervention is also anticipated to promote healthier dietary intake, characterized by more balanced eating patterns, and higher levels of physical activity. Delivered through individualized online guidance, this program is intended to encourage sustainable lifestyle changes and improve overall health. The study will involve an 8-week intervention conducted among overweight and obese healthcare workers at Dr. Hasan Sadikin General Hospital, Bandung.

Treatment and study plan

Personalized Nutrition Coaching

Behavioral

The intervention arm received 8 weeks of personalized nutrition coaching. During the intervention period, participants were provided with frequent follow-up through the WhatsApp application to discuss progress with a dietitian. In addition, scheduled follow-up counseling sessions were conducted via Zoom in week 3 and week 6 to evaluate the progress

Participants in the intervention group were also provided with a personalized meal plan, tailored to individual daily energy requirements, food preferences, and recommended menu options. Throughout the monitoring period, body weight was assessed weekly, while dietary intake was monitored three times per week on nonconsecutive days to evaluate adherence to the meal plan. Physical activity was monitored weekly using self reported physical activity using Standford 7 days Physical Activity Recall Questionnaire

Control (placebo) group

Other

The control group will receive nutrition education in the form of a booklet. The booklet provides information on balanced nutrition guidelines, recognizing hunger and satiety cues, mindful eating practices, and recommendations for physical activity.
