Ketone drink study reveals surprising effects on blood sugar and liver fat
NCT ID NCT06320522
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a ketone drink changes blood sugar and liver fat production in 12 healthy adults, comparing when they were fasted versus after a meal. Researchers wanted to understand if the drink's effects differ based on whether you've just eaten. The goal is to learn more about how ketones might help with conditions like fatty liver disease and type 2 diabetes.
