Effect of unprocessed red meat on obesity and related factors: A systematic review and meta‐analysis
Authors' conclusion
Studies did not show an effect of URM on weight gain, obesity, or related metabolic conditions. This may help clinicians when considering the use of URM for patients. Longer studies may be needed for observing obesity development in case the effect of URM on weight gain is small and needs a much longer time to express.
