@anomalon@actuallyautistic Me too. Earlier this year I solved a problem where I'd crash hard every day after I ate my "healthy" breakfast and "healthy" lunch with complex carbs, as per standard advice.
I learned most of us don't have enzymes to break down complex carbs, and have other metabolic difficulties, so I swapped everything for simple carbs. White bread, white potato, white noodles & pasta etc.
Suddenly, no more crashes and more stable energy than I'd had in years. We're different.
