Augmenting a hypocaloric ketogenic diet with exogenous ketone salts does not improve body composition outcomes (weight loss, fat loss, or lean mass preservation) compared to a ketogenic diet alone.
If you are doing a ketogenic diet for weight loss, adding exogenous ketone salts will not help you lose more fat or keep more muscle compared to doing the diet without them. The diet itself is the driver of body composition changes. You can save money by skipping the ketone salts.
Energy-matched hypocaloric ketogenic diets favorably affected body composition but were not further impacted by administration of an exogenous BHB-salt that augmented ketosis.
Why this rating
Randomized, double-blind, controlled-feeding study with objective imaging (DXA/MRI), but short duration (6 weeks) and small sample size (n=25 completers).
