With all due respect, I think that sounds like utterly BS. I was doing that for years and years. More and more carbs from "good sources" and all I got for my effort was more overweight and even poorer health and overall stamina.
I'm no LCHF zealot, as I'm sure everyone knows that by now. BUT I suffered for decades from the effects of the metabolic syndrome, insulin resistance blah blah blah. If I would make a list of the health benefits I gained when going low carb, some within days, some after maybe half a year or even longer, no one would believe me. No, I'm not religious about it. On the contrary, I'm very critical of the low carb concept. I would even say I loath some aspects of it. But, for me, they got something right. What's wrong is probably (at least partly) the hypotheses behind it all and the urge to bring things to their extremes (if less is better, nothing must be da shit!). I'm something as rare as a person that has regained her life through low carb or, more accurately, is aiming in that direction - I'm fuckin' thriving on low carb - but I'm still extremely critical to the low carb concept and especially to the low carb bullshitting and the commercialization of low carb, not to speak of the iconization of low carb gurus - the genuine ones and the copycats alike - and so on and so on. I don't know what specific parameter(s) in the low carb concept that brought my health back, I just know it did.
I think that we should be wary of the risk of throwing the good out with the bad when we criticize low carb or any other dietary regimen. Don't throw the baby out with the bath water. That some of us think low carb is, in most permutations and especially the more popular ones, a fake, doesn't necessarily mean they've got it all wrong.
Personally I think that the diet discussion using "either you are with us or against us" arguments is counter-productive. There's probably a grain of truth to be found in most dietary schools and the person that concatenates those grains to a whole, he will be the winner and worthy or several Nobel prizes. Hopefully I'm still around to benefit when and if that day comes.
I'm also more than pleasantly pissed (again) and I find that rather enjoyable.
Oh, and since at this level of intoxication I'm prone to throw proverbs and quotations around, let me finish by quoting Nietschze:
Whoever fights monsters should see to it that in the process he does not become a monster. So true, that. And so hard to live up to.
Any bad spelling or poor English is the whine speaking. Don't blame me - I'm an innocent bystander!
