About this trial
The research in this VA Merit will examine the effects of obesity and Post-COVID Conditions (PCC) on physical functioning, health-related quality of life, and adipose tissue inflammatory and cellular senescence profiles in older Veterans. Further, it will evaluate whether a weight loss intervention, including dietary modification and exercise, in obese Veterans with and without PCC will reduce systemic and adipose tissue inflammation and senescence and promote PCC recovery.
