Which age group has the lowest prevalence of being overweight after 20?

The age group of 20-29 years typically has the lowest prevalence of being overweight after the age of 20 due to several factors. In this early adult stage, individuals are often more active with higher metabolism rates and generally have fewer health issues that can contribute to weight gain. Additionally, lifestyle factors such as social activities, engagement in physical fitness and sports, and a focus on physical appearance can play roles in maintaining a healthy weight among younger adults.

As individuals transition into their thirties and beyond, physiological changes, including hormonal shifts, and lifestyle changes such as increased career and family responsibilities, often lead to decreased physical activity and potential weight gain. Understanding these trends aids in creating targeted interventions for weight management among different age groups.
