Official title: Effects of Ketogenic Diet on Alcohol Intoxication

Run by University of Pennsylvania · NCT07602270 · Data updated 2026-11-12

This study tests whether a 4‑week ketogenic diet changes how the brain works and how the body handles alcohol in adults who drink regularly.

Is this trial a fit for you?

Likely a good fit

Ideal participants are adults age 21–50 who have consumed multiple alcoholic drinks in the past month and are willing to follow a 4‑week ketogenic diet.

Probably not a fit

Participants who cannot refrain from certain medications or who have psychiatric conditions or positive drug screens may not benefit and may be excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Healthy adults with alcohol use concerns will follow a ketogenic diet for about four weeks and undergo three lab visits to measure brain chemistry, alcohol tolerance, and blood biomarkers. Lab visits include an alcohol tolerance test with controlled drinking and MRI scans at the start and after four weeks to assess NAD, lactate, glutamate, and GABA in the brain. The study uses breath alcohol testing, blood draws, urine screens, and safety assessments to monitor effects and eligibility.

Why it matters

Potential benefit: If successful, ketosis could offer new insights into brain energy use and how alcohol-related effects may be modulated.

How similar studies have gone: Prior research has explored metabolic effects on the brain, but this specific diet-alcohol interaction approach is relatively novel in humans.

Inclusion Criteria:

1. Age 21 years to 50 years old.
2. Willingness to provide signed, informed consent and commit to completing study procedures. Reported on at least one day in the month prior to consent of consuming 2 or more standard alcohol drinks on a single day.

Exclusion Criteria:

1. Unwilling or unable to refrain from use, within 24 hours of the alcohol lab procedures, psychoactive medications or medication that may affect study results.
2. Current DSM-5 diagnosis of any major psychiatric disorder (other than nicotine use disorders, or marijuana use disorders) as identified by clinical examination or structured interview that could interfere with study participation or make it hazardous for the subject.
3. Currently taking medication(s) that could interfere with study participation or make it hazardous for the subject to participate. (e.g. anticholinergics; antipsychotics; lithium; psychotropic drugs not otherwise specified)
4. Positive urine drug screen, positive for all substances but marijuana at screening or study visits (may be repeated once and if the result is negative on repeat, it is not exclusionary).
5. A current, clinically significant physical disease or abnormality on the basis of medical history, or routine laboratory evaluation that can impact brain function, the use of a ketone supplement, administration of ketogenic diet, or the use of alcohol (e.g., epilepsy, diabetes, irritable bowel syndrome, Crohn's disease, liver disease, kidney disease, kidney stones, chronic metabolic acidosis or a cardiomyopathy as determined by history and clinical exam).
6. Currently suffering from or has a history of stroke and/or stroke related spasticity.
7. Head trauma with loss of consciousness for more than 30 minutes or associated with skull fracture, inter-cranial bleeding or abnormal MRI (self-report, medical history).
8. Weight greater than 225lbs (Need to cap amount of alcohol given based on weight to individuals).
9. Females who are pregnant or breast-feeding
10. Contraindication to MRI, including presence of ferromagnetic objects, claustrophobia or fear of enclosed, medical conditions that prevent subjects from lying comfortably flat on his/ her back for up to 2 hrs.
