You really should read this. It’s listed as an opinion piece from the New York Times but the fact that “we” have been experimenting with antibiotics causing weight gain in animals AND humans since the 1950’s is interesting, to say the least. I have been seeing article after article bashing the “Paleo diet” for this and that. The one thing I always loved about it (though I don’t follow it due to lack of resources) is the push toward natural meats. This, right here, would be a fantastic reason to do our best to lessen our reliance on factory farmed meats.
