This thread is going reveal to a lot of people just how bad the science around sugar is right now.

Generally speaking, the point is not to consume too much and that would be nice except oops! our economic system is based on excessive consumption and sugar is kind of a really cheap ingredient to just add to make your food, so lets do a bunch of mental gymnastics so we don't have to explain why it's legal to sell canned diabetes with its 900 grams per can.

The fact it lacks nutrients and protein is another huge problem, you can go malnourished for awhile but because your body doesn't produce enough protein on its own, you can literally starve to death if you don't get it from other sources. Insulin is also needed alongside glucose to get energy where it needs to be so too much at once can overwhelm you and if do this long enough and you'll get the type 2.

So make sure you're getting all your nutrients, make sure you're getting your proteins, and don't consume too much or too fast. It's certainly possible to do all of this through a nontraditional diet but our society and body has kind of evolved to create the optimal solution for keeping us alive in a sustainable fashion, or at least that WAS the case until capitalism started putting profits over human lives.

EDIT: Didn't know where to put this so i'll tack it on to the end. You can actually get huge energy spikes by consuming the glucose by itself (sold in stores as dextrose) as it's basically pure energy, however since our bodies are designed to consume Glucose and Fructose in equal amounts you'll be literally running on half power. This is also why fructose in any ratio more than 50% is really bad for you as while glucose can back up without any ill effects, fructose actually does have some harmful side effects while hanging out in your bloodstream and it's theorized that's the primary reason why processed food (especially HFCS) is so bad for you.
