Previous studies have shown that probiotics’ benefits range from improved immunity to reduced acne. Now, new research suggests these good bacteria may shrink body fat, too.

Canadian scientists found that when 28 healthy but overweight participants ate yogurt containing both Lactobacillus fermentum and Lactobacillus amylovorus, all of them lost body fat. In fact, people who ate yogurt fortified with the L. amylovorus strain lost 4 percent body fat, a statistically significant figure, suggesting that gut microflora may increase metabolism.
