Summary

This trial is comparing the effects of a ketogenic low-carbohydrate diet and a low-fat diet in adults with mild cognitive impairment.

Who is the study for?
Adults with mild cognitive impairment who are stable medically and on medications can join this study. They need an informant to provide additional information about them. People with significant sensory impairments, liver issues, other neurodegenerative diseases besides MCI, MRI contraindications, active cancer (except certain types), recent seizures or strokes, major psychiatric disorders, diabetes needing medication, or serious illnesses cannot participate.
What is being tested?
The BEAT-AD study is testing if a ketogenic low-carbohydrate diet versus a low-fat diet affects cognitive function in adults with mild cognitive impairment over 16 weeks. Participants will be randomly assigned to one of the diets and monitored for changes in brain function and biomarkers related to Alzheimer's disease.
What are the potential side effects?
Potential side effects from dietary changes may include gastrointestinal discomfort like constipation or diarrhea when adjusting to the new diet. The ketogenic diet might also cause temporary fatigue or headaches as the body adapts.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Modified Mediterranean Ketogenic DietExperimental Treatment1 Intervention
The MMKD is a low carbohydrate/high fat diet aimed at inducing ketosis, as the experimental diet in the proposed study. Participants on the MMKD will keep their daily carbohydrate consumption below 20 grams per day throughout the 4 month intervention.The MMKD group will be supplied with extra virgin olive oil during their in person visits to use as a source of fat in their diet, and will be encouraged to eat plentiful fish, lean meats, and nutrient rich foods that meet the requirement of \<20 grams total carbohydrates per day. Participants will receive a daily multivitamin (Centrum Silver) over the course of the study and instructed to take 1 tablet each day while on the diet.
Group II: American Heart Association DietExperimental Treatment1 Intervention
The American Heart Association Diet (AHAD), is a low fat/high carbohydrate diet (\<40 grams/day) will be used as the control diet. Participants on the AHAD will be encouraged to limit their amount of fat intake to \<40 grams/day, while eating plentiful fruits, vegetables, and carbohydrates containing adequate fiber. Participants will receive the same daily multivitamin supplement (Centrum Silver) over the course of the study and instructed to take 1 tablet each day while on the diet.
