Fasting and diurnal blood ketonemia and glycemia responses to a six-week energy-controlled ketogenic diet supplemented with racemic R/S-BHB salts

Randomized trial in non-diabetic adults with overweight or obesity on a 6-week ketogenic diet with twice-daily racemic BHB salts (6 g R plus 6 g S per serving) or placebo. Fasting R-BHB rose 1.0 mM on the diet and 26 percent more with the salts. Diurnal R-BHB was 40 percent higher with salts, and fasting glucose fell beyond diet alone.
