Family Patterns in Resting Metabolic Rate Between Parents and Adult Children

This study examines whether resting metabolic rate (RMR)-the amount of energy the body uses at rest-is similar between biological parents and their adult children (aged 18 years and older). RMR is the largest component of daily energy expenditure and plays an important role in body weight regulation and overall metabolic health. Participants from the same family will undergo a single testing session in a metabolic laboratory. RMR will be measured using indirect calorimetry under standardized conditions, along with body composition assessment and basic health information. The primary goal is to determine whether RMR is correlated within families. The study will also assess whether these similarities remain after accounting for differences in body composition, age, and sex. This observational study will help improve understanding of how metabolism varies between individuals and the extent to which these differences may be influenced by familial or inherited factors. Findings may contribute to future research on personalized nutrition, obesity risk, and metabolic health.
