Step Count Prescription to Improve Body Composition and Heart Health in Overweight and Obese Adults Aged 20 and Older

What this Trial Is About

Researchers are studying how daily step counts related to body fat affect body composition and cardiometabolic risk in overweight and obese adults aged 20 and older. The goal is to develop a model that helps prescribe personalized physical activity targets to achieve specific weight loss and improve health while eating normally. This study includes adults from young to older age groups and aims to better understand how step counts relative to fat mass predict weight and health outcomes. Participants will use triaxial pedometers to track their daily steps, which will be adjusted for body fat mass. The study has two phases the first phase measures the relationship between step counts and body composition over four weeks, and the second phase tests if following personalized step count targets for eight months leads to predictable weight loss and health improvements. Step counts are monitored continuously, and participants receive support and encouragement to meet their goals. During the study, participants undergo detailed body composition assessments using multiple methods including DEXA scans, and provide blood samples to measure markers related to cardiometabolic risk. They record dietary intake for analysis and attend laboratory visits at baseline, midway, and study end for follow-up measurements. Researchers track adherence to step count goals and changes in weight, body fat, and cardiometabolic health markers over the study period to evaluate outcomes.
