Fats come with their own issues too, especially the shelf stable fats that processed food uses as opposed to a bit of real butter.

The truth is less exciting: avoid too much sugar or fat. Some is fine. Your "fine" and your "too much" may be different from someone elses.

Yeah, fats definitely have issues, but, they come with rate limiters - satiation triggers. Heart of his argument is that fructose triggers nothing, so you keep chugging it, and with almost identical stress to liver as alcohol, which also has a limiter for most people (you pass out :) )
