Which in itself should be a red flag since the aetiology and myriad confounding factors that go along with metabolic syndrome means that conflating the two conditions is patently an erroneous oversimplification that renders the advice meaningless for the sake of neatness.
Even with regard to just the actual diabetes there are endless nuances and distinctions which bring about differences in overall morbidity risk. My avatar is watching anyone who thinks that type 1 and type 2 should be lumped together in this.
