npub1ufmlneg8tt9jwvk6p40t02lxhmkns6zlpu4cwrvxerczdnn4syzqlgqhp4 (npub1ufm…qhp4) wasn't clear but sugar here refers to the mono/di-oses in processed foods, not the glycogen you'd get from meat or other complex carbs.
it's true that the brain needs glucose and won't get ATP directly from other metabolism but the gycemic absorbtion profile does have the feedback loop of increasing your blood sugar more than the equivalent amount of complex carbs would.
Splitting hairs here but yeah.
