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.
