Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the impact of two plant-based diets-whole food plant-based (WFPB) and plant-based meat alternatives (PBMA)-vs. an omnivorous diet (Animal) on endurance and muscular strength in recreational athletes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The SWAP-MEAT study compared the impact of consuming diets containing animal meat (primarily beef and pork) vs. plant-based alternative meats (Beyond Meat products) on health risk factors, cardiometabolic risk factors, and the gut microbiome in generally healthy adults. The SWAP-MEAT Athlete pilot study explored the impact of these diets on athletic performance instead of health biomarkers and cardiovascular disease.

The purpose of this study is to replicate the pilot study with the exception of using undergraduate students who have access to Stanford dining halls, rather than graduate students who have to buy and prepare their own food. It will be a 2x4-6 week randomized crossover trial that contains two arms: animal meat and plant-based alternative meat. Generally healthy recreational athletes will be recruited and complete athletic performance field tests at the end of each diet in order to assess athletic performance outcomes. From the SWAP-MEAT: Athlete pilot study, the investigators can attest to the feasibility of the trial and have justification for conducting this larger study.

This study will aim to focus on BIPOC (Black, Indigenous, People of Color) undergraduate students. By doing so, the investigators can gain a better understanding of the potential barriers and challenges to their adoption in diverse populations, for example, understanding of how cultural differences influence dietary choices and preconceptions about plant-based diets and animal protein alternatives. This study aims to address these limitations and provide valuable insights into the effectiveness of plant-based diets for recreational athletes, as well as potential barriers and challenges to their adoption in diverse populations.

RANDOMIZED

Intervention Model

CROSSOVER

SWAP-MEAT Athlete is a randomized crossover trial in which 10 recreational runners and 10 recreational resistance trainers are assigned to one of six possible diet orders. Each diet order contains three phases for 4 to 6 weeks each (4 weeks for universities on the quarter system; 6 weeks for universities on the semester system) -Animal, Plant-Based Meat Alternatives (PBMA), and Whole Food Plant-Based (WFPB)-in random order.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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 duration of the study.
* Participants will be on a Stanford meal plan which allows them access to the nine dining halls on the Stanford campus.

Exclusion Criteria
