In theory probiotics can lose weight because through the intake of probiotics, the dysbiosis of intestinal flora can be corrected so that the bacteria that cause obesity can be reduced or disappeared, so that the symptoms of obesity can be relieved and weight loss can be successful. However, in practice, the intake of probiotics will be accompanied by a large amount of sugar, which will produce a lot of calories, and these calories will cause weight gain. So currently weight loss with probiotics varies from person to person, and only through a small amount of energy intake and increased exercise is the right way to lose weight, and probiotic weight loss is open to debate.
