ClinConnect Summary

This clinical trial is looking into why some people remain very thin, or "super lean," even when obesity rates are rising in the general population. The researchers want to understand the lifestyles and genetic factors that allow these individuals to maintain a body mass index (BMI) below 18.5, which is considered very low. By studying both super lean individuals and those with a normal weight, they hope to find out what keeps some people resistant to weight gain.

To participate in this study, you need to be between 20 and 40 years old. If you have a BMI between 15 and 18 (for super lean participants) or between 20 and 25 (for control participants), and you are generally healthy without any eating disorders or diabetes, you may qualify. Women who are pregnant or breastfeeding cannot participate. If you join the study, you can expect to share information about your health and lifestyle, which will help researchers learn more about the reasons behind super lean body types. This research could provide important insights into obesity and health.
