When a patient shows up with a blood glucose >300 mg/dl it is mystifying why a doctor would not simply give them a pamphlet about konjac noodles and a coupon for $3 off cauliflower crust pizza. Surely it must be a conspiracy when you hear things like “treating acute hyperglycemia” and “preventing imminent kidney failure, coma and death” as opposed to “have you heard of keto tik tok?” Perhaps the ADA should encourage…
How many people are willing to eat cauliflower crust pizza? Dietary changes have utterly failed in practice at treating any other condition within the population at large outside of perhaps avoiding nuts.
That being said most of the time dietary changes fail isn't because the suggested diet doesn't work it's because the people are just unwilling to follow it.
That's also no reason to not take a multi-pronged approach of recommending dietary changes and pharmaceutical interventions.
