He gave an example of Japanese and their healthiness, yet they eat way more fructose than the USA citizen he cites. There's a whole other bunch of misinformation in his speech and his studies are filled with flawed design (no control group, p hacking etc.).
I swear every time I'm in a nutrition related thread I see somebody mention his name or a book he wrote or talk he did. I used to be pretty deep into weightlifting and nutrition, and I don't know that I ever once ran into his name in all my reading, and I spent a stupid amount of time reading about macro + micro nutrients.

You can check the sources yourself too.
Although, I believe Lustig changed the narrative and is currently promoting diets rich in starch (which means high volume - low calories) and most of his studies produce a caloric deficit (while he denies it despite the fact that less calories are metabolized due to digestion of starch).
I believe he also likes referencing fructose extract consumption studies that have no direct mapping to a real diet. For example, consumping 100g of fructose through fruit won't do you any harm.
