At 1h29m, I will take your tl;dw crib notes as I have heard similar speak in the past of the issues around fructose. Particularly, the doc Sugar Coated comes to mind (http://sugarcoateddoc.com/).
I’m guessing then the suggestion is that it’s just a two-prong problem then: caffeine (enough) and fructose (like 1000 extra calories or more per day for multiple cans).
