Eligibility Criteria
You may qualify if:
- Generally healthy omnivorous adults between 18 and 35 years of age who report typically consuming at least 1 serving of meat per day and are willing to consume \~2 servings per day of animal meat, plant-based meat alternatives, and whole-food plant proteins.
- Participants will have been consistent recreational runners or weightlifters (3-4 times per week) for at least the prior 1 year, and currently run or lift 3-4 times per week.
- Runners will engage in at least 150 minutes of moderate-to-vigorous aerobic activity or 75 minutes of vigorous activity per week. All participants will have habitually consumed an omnivorous diet for at least months.
- Participants will have self-reported good health and BMI 18.5-30.0.
- Participants must be able to commit to running or resistance training at least 3-4 times per week for the 12 week duration of the study.
You may not qualify if:
- Individuals who have participated in any restrictive diet within the last month, have any known nutrient intolerances, have orthopedic limitations, are participating in any other physical activity or diet study;
- Individuals consuming any performance enhancing drugs or medications known to interfere with athletic performance;
- Individuals who have a chronic disease or eating disorder, are currently pregnant or intend to become pregnant in the next three months, or have an intent to compete in any physical activity competition within the next 3 months.
