Summary

This trial compares plant-based diets with an animal meat diet to see how they affect athletic performance in healthy undergraduate athletes, especially focusing on BIPOC students. It aims to understand how these diets influence endurance and strength and to identify any cultural barriers to adopting plant-based diets.

Who is the study for?
This trial is for healthy, recreational athletes aged 18-35 with a BMI of 18.5-30 who run or lift weights regularly (3-4 times per week) and have been doing so consistently for the past year. They must eat meat daily, be on a Stanford meal plan, and not be pregnant or planning to compete in physical competitions soon.
What is being tested?
The study compares the effects of three diets on athletic performance: an omnivorous diet (Animal), a whole food plant-based diet (WFPB), and a diet including plant-based meat alternatives (PBMA). Participants will alternate between these diets while maintaining their regular exercise routines.
What are the potential side effects?
Since this trial involves dietary changes rather than medication, side effects may include digestive adjustments to new foods, potential nutrient deficiencies if not balanced correctly, and individual reactions to different types of proteins.

Other Research
Common treatments for health behaviors, particularly through dietary modifications, work by altering the intake of macronutrients such as fats, carbohydrates, and proteins. For example, low-carbohydrate diets can improve insulin sensitivity and promote weight loss, while Mediterranean diets, rich in healthy fats and vegetables, can reduce inflammation and improve cardiovascular health. These mechanisms are important for patients as they help in selecting the most suitable dietary strategy based on individual health goals, preferences, and metabolic responses, ultimately enhancing adherence and long-term health outcomes.
