I'm sorry that I didn't point out explicitly that Mark Sisson has a variety of businesses that sell supplements and certifications in his nutritional philosophy. I personally do not benefit one whit if someone buys something from him. But does profiting from their work preclude us from bringing up their work? I understand that it's a good rule of thumb, when determining trustworthiness, to consider profit-motive. But the supplement industry is huge: people argue whether it's $12 billion or $37 billion, and I don't begrudge a nutrition and health advocate to try to make money this way. Especially considering how dubious most supplements are, Mark seems pretty transparent about which supplements he recommends and sells.

But you're contention, as I understand it, is that the author is not to be trusted. What is the author asking you to believe in? As I understand Mark Sisson's work, it is to eat nutritious food, get most of your calories from fat, protein, and carbs, in descending order, to minimize carbs to something like 100 grams a day or less, to eat when hungry, to not overeat, to exercise with low-level aerobic activity and occasional heavy lifting. That I got from the podcast episode linked above.
