It&#x27;s tough to hear but no matter what your genetics or internal flora are, <i>being overweight is still your fault</i>.  It may not be &quot;fair&quot; that someone puts on less weight than someone else eating the same diet, but ultimately you&#x27;re the one responsible for maintaining your own weight (by controlling what you put in your mouth) no matter what the state of your gut microbes.<p>edit: not picking on you Onion2k...I end up commenting a lot on these stories because it really irks me when so many articles and people are looking for something external to blame for their weight problem.  You may or may not be able to change your metabolism but you absolutely can change the number of calories you&#x27;re consuming.
