Pilot trial of an motivational Interviewing-Cognitive behavioral therapy ketogenic nutrition adherence program for older adults
NCT ID NCT04817176
First seen Oct 22, 2026 · Last updated Oct 23, 2026 · Updated 1 time
Summary
Objective 1: Assess feasibility and acceptability of all protocol components of a pilot trial testing a 6-week telehealth Mediterranean ketogenic nutrition adherence (KNA) program using motivational interviewing and cognitive behavioral strategies (MI-CBT) compared to a KN information only group for older adults with mild cognitive impairment (MCI) to prepare for a full-scale trial. Specifically, the investigators will examine the feasibility of the recruitment, retention, assessment, and intervention delivery methods. The investigators hypothesize that: 1. The study protocol will result in high patient retention (90%) and patient attendance of intervention sessions (80%), and 2. A centralized MI-CBT telehealth delivery approach will be associated with high intervention acceptability ratings from patients. Objective 2: Assess signal of initial effect of the KNA program on important clinical outcomes and adherence relative to a KN information-only condition. The investigators hypothesize that patients in the KNA condition, relative to the KN-only condition, will show: 1. higher rates of clinically significant improvements on the RBANS total scale scores, improvements in daily functioning (FSQ), and decreases in patient CAIDE risk score( (Cardiovascular Risk Factors, Aging, and Incidence of Dementia), and 2. improved adherence to KN, as evidenced by higher levels of measurable urine ketones in the KNA condition compared to the KN-only condition.
