About the study

The goal of this clinical trial is to learn if consuming a higher protein diet that includes one serving of beef each day, in combination with resistance exercise, improves wellbeing in postmenopausal women. It will also tell us about how higher protein intake changes body composition and blood values related to health. The main questions it aims to answer are:

* Does higher protein intake combined with resistance training improve mood and sleep in postmenopausal women? * What other health benefits to postmenopausal women experience when the follow a higher protein diet and participate in resistance exercise?

Researchers will compare three groups 1) postmenopausal women living their daily lives as usual, 2) postmenopausal women consuming a higher protein diet, and 2) postmenopausal women consuming a higher protein diet and participating in resistance training.

Participants will:

* Consume a higher protein diet for 16 weeks * Participate in an at-home resistance training for 16 weeks * Keep a diary of their food intake, sleep habits, and mood * Have health assessments every 4 weeks

What is being tested

• Diet - higher protein (other)
• Physical activity and resistance training (behavioral)
