Bacon
I think I've learned to distrust 'debunking', fact-checking or anything that confuses 'facts' with opinions. Especially when there are vested interests involved. So the first mythbusted rather put me off, ie 'insulin is your fat storage hormone'.
That's pretty typical of this kind of 'debunking' presentation, ie setting up strawmen and then framing the argument in favor of whatever they're selling.
IMHO, it's a reasonable description of what insulin does. So normal person may have 6-7g of (total) blood sugars floating around. If that increases, insulin's produced to get deal with any excess. So a 'use it, or lose it' response. Or store it for later, ie in lipocytes, so fat gain and thus weight gain.. And then increased visceral fat leading to insulin/metabolic syndrome, and why we're here.
The rest seemed to dance around the differences between food intake and the results of from those foods, which is again pretty normal as the presenter's selling a $29/month coaching service. That's promoting veganism, which isn't without it's own risks, and for me, ignores something very fundamental. We're not evolved to be vegan. We're evolved to use energy from veg/meat/fats and so have the processes to use or store energy from carbs, fats or proteins. We even used our large cranial capacities and opposable thumbs to be able to convert herbivores, which can process plants better than us into more nutritious foods like bacon. When vegans start evolving the same digestive systems as ruminants, then maybe I'll consider it a 'natural' diet.. For them at least.
