New research shows that some fibers may help with weight loss in ways similar to popular medications. A study from the University of Arizona and the University of Vienna found that beta-glucan — a fiber in oats, barley, and certain mushrooms — was especially effective in helping mice control weight. Out of all the fibers tested, only beta-glucan reduced body fat and weight in mice on a high-fat diet, suggesting it may be helpful for weight management.

Beta-glucan is special because it helps with weight loss and also boosts the immune system. This soluble fiber increases the variety of good bacteria in the gut, which helps reduce inflammation, improve gut health, and support insulin regulation.

Beta-glucan also raises levels of butyrate, a compound that triggers the release of GLP-1, a protein that controls insulin and appetite — similar to the effects of the drug Ozempic. Other fibers, like wheat dextrin and pectin, changed gut bacteria but didn’t have the same impact on weight loss.

While more research is needed to see if these benefits translate to humans, the findings suggest that not all fibers are equal. For those looking to manage weight and support immune health, beta-glucan offers promising benefits, adding another layer to the already strong health advantages of dietary fiber.
