New checkoff-funded research adds to growing evidence that fresh beef can play a role in a healthy, sustainable diet without contributing to obesity. While animal-sourced foods such as red meat often are linked to weight concerns, Texas Tech University researchers found no significant effect of unprocessed red meat intake on weight gain or related metabolic issues in adults.
Led by Nikhil Dhurandhar, chair of the Department of Nutritional Sciences, the team conducted a systematic review and meta-analysis of 19 human clinical trials. Unlike earlier studies that relied on self-reported dietary data, this research analyzed controlled feeding studies to deliver the most comprehensive evaluation of beef intake and obesity to date.
“Beef provides high-quality protein and essential nutrients, but people are often discouraged from consuming it due to observational studies that may not accurately reflect cause and effect,” Dhurandhar said. “Our review found no protective or adverse effects of unprocessed red meat on obesity.”
Dhurandhar noted that protein-rich foods such as beef can help improve satiety and support weight management. However, negative perceptions may prevent consumers from realizing these potential benefits. This study aims to give clinicians and consumers evidence-based information to make informed choices about beef’s role in balanced diets.
