Patients with diabetes, gastrointestinal diseases, or those on specific medications affecting metabolism may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study examines the impact of consuming lean beef on cardiometabolic health and the gut microbiome over a 6-week period. Participants will be randomly assigned to one of three diets: lean grain-fed beef, lean grass-fed beef, or plant-based meat. The trial aims to assess various metabolic, inflammatory, and gut microbiome markers to determine the health effects of these dietary interventions.

Why it matters

Potential benefit: If successful, this study could provide insights into dietary recommendations that improve heart health and gut microbiome balance.

How similar studies have gone: While there have been studies on diet and gut health, this specific approach comparing different types of beef and plant-based meat is relatively novel.
