Study how ketone changes in the body with diet and fasting
Treatments studied
Part of Hormones & metabolism clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between ages 20 and 70
- Be able to follow study rules: fast over 10 hours (water only), no alcohol for 24 hours, and no exercise for 24 hours before test day
- Avoid low-carbohydrate dieting (less than 30% of calories from carbs) and avoid taking ketone supplements in the last 4 months
- Have no major, uncontrolled health problems (especially high blood pressure, heart/lung/liver/kidney issues, endocrine issues like diabetes, major neurologic or psychiatric conditions)
- Have no allergies or sensitivities to common drink ingredients (including milk/soy/wheat and shellfish/fish/eggs/nuts/peanuts)

This study tests if a ketone supplement can reduce protein in urine and protect kidney function in people with chronic kidney disease or polycystic kidney disease. You drink a special supplement and researchers measure how it affects your kidneys.
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 trial tests if taking a ketone supplement can reduce alcohol cravings and drinking in people with mild to moderate alcohol use disorder who are not currently seeking treatment. You will have MRI scans, PET scans, and supervised drinking sessions to see how the supplement affects your brain and alcohol intake.
This study tests how a ketone ester drink changes the bacteria in your gut. You'll drink the supplement and fill out questionnaires online. It's for healthy adults who want to help researchers understand gut health.
This early-stage study compares how quickly and effectively a low-carbohydrate diet versus taking ketone supplements helps the heart use less sugar (measured with PET/CT scans). It also looks at how long it takes to reach a “ketosis” state, which may be helpful for metabolic health.
This trial tests how a ketone drink affects the brain in healthy middle-aged adults. It may help researchers understand if ketones can support brain function.
