Summary

This study looks at whether eating almonds twice a day for 12 weeks can improve physical performance, aerobic capacity, and daily activity in overweight but active adults aged 50-59. Participants will compare almonds to a calorie-matched snack to see if almonds offer extra benefits for energy, body composition, and well-being.
