Sorry you're getting downvoted. He is a bit hyperbolic, but his steps are extremely easy to understand and can help curb bad habits that a lot of Americans have. He is also a likeable person I think and that means more people will listen to him than better (perhaps) advice coming from college professors who wrote a book on the same subject but who are less charismatic. A lot of HN people will downvote you for being a "shill" or "I know someone better" but you are on point and don't let the downvotes be taken personally. It's a failure on the downvoter rather than you when you are on topic and relating pertinent information.
