Summary

This study looks at whether eating whole eggs (which contain cholesterol) helps people aged 50-69 gain more muscle from resistance training compared to eating only egg whites. Thirty-six participants will either do weight training or remain sedentary for 12 weeks while consuming eggs or egg whites. Researchers will measure changes in muscle mass, strength, blood lipids, and inflammation to see if dietary cholesterol plays a role in muscle growth.
