I'm not saying the article is worthless, but it's got a stench of "businessman's succcess qualifies him as an expert on everything"

And I'm on board with "you are what you eat"

I'm curious about carbs/sugar though. My mental state plummets if I eat too much. Or do I eat carbs because my mental state has already plummeted, as they're easy and rewarding...? And closer? (I have a convenience store opposite my house)
