Good for Brian not being one of the annoying retard diet zealots who go around claiming their way is the only way and insulting those who don't follow it even if they're getting great results on another diet (usually with the "you'd lose even more if" type strawmen.) I think some of it is just due to marketing, they won't make money as a "diet coach" if people just do their own thing instead of following their specific program, but you also find zealots who simply go around acting annoyingly smug at anyone who isn't also on keto or a carnie or a fastnatic, etc.
