Fructose and ketones

Exogenous ketones have been said to lower blood glucose levels (perhaps mediated by how much glycogen is being converted by the body to glucose, etc.)

Do you know if a similar relationship exists with blood fructose? I guess so. But I haven’t had a chance to dig into the literature yet.

Probably but you’re better off with the glucose.

Effect is rather small for exogenous ketones.

Exogenous ketosis in patients with type 2 diabetes: Safety, tolerability and effect on glycaemic control - PMC).

Compared to baseline and follow‐up, exogenous ketosis decreased mean blood glucose from 7.8 ± 1.4 mM to 7.4 ± 1.3 mM (140 ± 23 mg/dL to 133 ± 25 mg/dL) (p < .01).

Oyster mushrooms seem to be better.

The fasting glucose level decreased by 1.9 points. The concentration of HbA1c, a marker for exposure to a high glucose level over a longer period, decreased by 1.1 points.

1.9 mmol is about 34 mg/dl

They used dried oyster mushroom powder, capsulized, and the dose was 3 grams of powder per day.
