Ketone drink and exercise fuel use in trained cyclists
Part of Hormones & metabolism clinical trials.
This study tests if drinking a ketone supplement before exercise changes how your body uses carbs for fuel. It may help trained cyclists and triathletes understand fuel efficiency.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 50 years old
- You are a trained cyclist or triathlete with a high fitness level (VO2peak above 55 for men, 48 for women)
- You are generally healthy and not taking medications that affect stomach acid, cholesterol, or inflammation
- You do not smoke and are not pregnant (if female)
- You are not on a low-carb diet and have not donated blood in the last 2 months

This study tests if taking a ketone drink before intense cycling helps your heart recover faster afterwards. It's for healthy recreational cyclists who are very fit for their age and sex.
This study tests whether drinking a ketone supplement helps your body adapt better during a 5-week altitude training program. You would live at high altitude but train at low altitude.
This study is testing how taking ketone and carbohydrate supplements affects performance in trained cyclists. It is looking for male amateur cyclists who train regularly and have a high fitness level.
This study looks at whether taking a special drink (ketone supplement) with carbohydrates can help improve your cycling performance when you are riding at a very hard effort level.
This study tests whether a special ketone drink can improve exercise ability and heart function in people with type 2 diabetes. Participants will have two treadmill exercise tests and heart MRI scans to see how the drink affects their performance and cardiac efficiency.
This study looks at how your body processes “ketones,” which are energy molecules that rise with fasting or low carbohydrate intake. You may be asked to follow strict diet and activity rules before test days so researchers can see what affects ketone metabolism.
