> I'm very skeptical. I think there are some things that may make us "feel hungrier" but there's nothing changing our metabolism. > If we are to believe this, it would mean that "plastic" is making our bodies so much more efficient that there's extra energy that's being stored as fat. I think it's likely the opposite, e.g. there's something (not necessarily plastic) throwing off hormones, so the body ends up storing more of the calories as fat than it would if it was healthy. It's not at all clear (to me, at least) that a healthy human body would continue to store fat indefinitely, regardless of how many calories were being consumed.
