Basically our bodies are good at dealing with 50/50 G:F ratios, but HFCS is more like, 40/60 so it doesn't know what to do with that excess F which is known to cause all sorts of health problems. This is why fruit and table sugar are fine but most processed food is not. If you know how to avoid it you can end up a lot healthier overall. And no, the meme of "the fiber of the fruit prevents absorption" that doesn't stop it, just smooths down the sugar spike over a larger time. All of it that was diversion tactics to distract people from the real source of health problems: HFCS and overconsumption, because health science in the US is notoriously bought and paid for and they're not about to blame capitalism.

Basically I wanted to see if it would be possible to survive off of nothing but energy so I experimented on myself and short of some minor issues (malnutrition and something I learned about called protein starvation) it caused me to be healthier and happier once I knew what I was doing.

EDIT: Have to explain protein starvation because google's dogshit algorithm thinks you mean protein toxicity which his the literal exact opposite of what protein starvation is and because it's so confident that's what you want to see it won't actually tell you: So like humans need protein and we can generate it from energy, but the rate is way too low for our bodies to function so you're only getting like a 10th of what we need, meaning you can starve to death while having more than enough calories otherwise.

Also while I'm here I may as well also go further into what I meant by "good at dealing with G:F at a 50/50 ratio" on the cellular level we have little factories pumping energy across a barrier so that it can later spin a literal turbine and generate ATP, and they're built out so that sugar comes in, gets broken into Glucose and Fructose and like Factorio the ratios are set to fit that. Start producing too much Fructose and now you have an imbalance and like Factorio causes things to back up a bit. This is also why I was at half energy when I did Glucose-only; I had all the energy I needed but the rate I could access it was half of what it should have been. TL;DR Our cells are designed to reverse the effects of photosynthesis, converting sugar into energy, everything else is on top of that is ultimately in service of that goal.

Takeaway: Sugar is good, potatoes and PB toast are great, HFCS are bad, and capitalism is to blame for the health problems in america.
