Triple Therapy Targets Diabetes and Muscle Loss in Elderly Adults

This completed clinical trial investigated whether combining three specific interventions could help elderly adults with type 2 diabetes maintain muscle mass while improving metabolic health. The study enrolled 100 men and women aged 65 and older who had diabetes and low physical activity levels.

The trial tested three interventions designed to create negative energy balance: circuit resistance training performed at home three times weekly, a plant-based Mediterranean diet limiting eggs, dairy, and fish while avoiding meat and poultry, and empagliflozin 10mg daily (a diabetes medication that causes calorie loss through increased glucose excretion). Participants were initially randomized to one intervention for 10 weeks, then resistance training was added to the diet and medication groups for another 10 weeks.

Researchers measured lean body mass, body weight, fat percentage, muscle strength, physical function, blood sugar control (HbA1c), and blood pressure. The study specifically focused on sarcopenia measures - the age-related loss of muscle mass and strength that significantly impacts quality of life and longevity in older adults.

This research addresses a critical health challenge: elderly adults with diabetes face accelerated muscle loss, reduced physical function, and increased frailty risk. By testing interventions that work through different mechanisms - exercise building muscle, dietary changes optimizing nutrition, and medication improving glucose metabolism - the study aimed to identify optimal combinations for preserving physical function and metabolic health during aging, potentially extending healthspan and independence in this vulnerable population.
