I disagree, I think it’s fairly easy to read this passage in particular

> The simplest solution to a lot of problems is consuming less with the assumption that, most of us (maybe not you), have a lot of spare energy sitting around.

as energy-woo / thanks-I’m-cured material.

You can weasel your way around criticism by calling it “a general and fairly anodyne opinion about what might be a solution to a problem some people have,” but consider -

It does make sense that someone who’s struggled with a chronic condition would be tired and embittered by the endless snake oil evangelizing they’ve had to endure, on top of already struggling with their health.

(Not that fasting doesn’t work for some people, as you say! it’s more the grandiose claim that it’s “The simplest solution to a lot of problems” coupled with some vague anecdote about blood work and knowing better than doctors that waves a red flag)
