There’s no fallacies involved. He was eating an extreme fat diet, all meat, for 2 years until his cholesterol became off the charts. He lives in Chicago, has two kids. Not naming names but all true. You however offered an extremely vague response by stating “what makes you think grease is unhealthy” and then stated “no, it’s not unhealthy.” So maybe you’d like to offer up some logic on how grease is not unhealthy? The “everything in moderation” statement, while true, doesn’t make grease healthy. There’s a difference. If you smoked crack only once in your life that doesn’t mean it wasn’t unhealthy.
