What this Trial Is About
Researchers are studying postmenopausal women to see if a higher protein diet including a daily serving of beef, combined with resistance exercise, can improve wellbeing. The study aims to find out if this combination improves mood and sleep and to explore other health benefits related to body composition and blood health measures. It compares three groups: women living normally, those on a higher protein diet, and those on that diet plus resistance training. Participants follow their usual diet or adopt a higher protein diet with beef consumption seven days a week, providing about 25 grams of protein per serving. One group also completes 150 minutes of physical activity weekly, including strength training sessions three times per week. These interventions are maintained for 16 weeks, with participants in the control group continuing their normal diet and activity patterns. During the study, participants keep diaries tracking their food intake, sleep, and mood. They undergo health assessments every four weeks, including measurements of sleep quality and duration, mood, quality of life, body composition, bone density, weight, and blood amino acid levels. The study monitors these outcomes over the 16-week period to assess changes related to diet and exercise interventions.
