A Review on Role of Microbiome in Obesity and Antiobesity Properties of Probiotic Supplements

In simple terms

This study is like a school report that collects and retells what other scientists have found. It doesn’t do its own experiment, so it can’t prove anything new. It helps us see patterns and ideas, but we can’t say for sure if probiotics really cause weight loss just from this.
