Your assumption is that obese &#x2F; overweight individuals are seeking abnormally inefficient bacteria, as opposed to their perhaps having abnormally <i>efficient</i> microbes. I&#x27;m sure the world of the overweight is comprised of many types: those who simply overeat beyond their &quot;normal&quot; bacteria&#x27;s ability, those who eat their way to super-efficiency, those who accidentally (antibiotics, food poisoning maybe, Caesarean-section-delivery -- who knows?) arrive there, etc.<p>Simply labeling it a problem of self-control paints with far too wide (and pejorative) a brush. Let&#x27;s assume a hospitalization somehow leaves you with a more efficient gut -- how easily can you stop eating, say, 250 calories a day? (Research shows: not easily, and not forever.)
