The Claim

Ketogenic diets result in decreased blood glucose concentrations in adults, with a mean difference of -0.18 mmol/L (95% CI: -0.33 to -0.02) based on pooled data from 27 randomized controlled trials.

Source: Impact of the ketogenic diet as a dietary approach on cardiovascular disease risk factors: a meta-analysis of randomized clinical trials.

What the research says

1 study

  1. Study: Impact of the ketogenic diet as a dietary approach on cardiovascular disease risk factors: a meta-analysis of randomized clinical trials.

    This study looked at 27 high-quality research trials testing whether ketogenic diets lower blood sugar, and found they do - lowering it by about 0.18 mmol/L on average, with the true effect likely between 0.02 and 0.33 mmol/L lower. This matches the claim exactly.
