Obesity Clinical Trial - Time Restricted Eating for Metabolic &

Status Recruiting

Clinical Trial Summary

Obesity and related metabolic comorbidities have been associated with more than a 4-fold increased risk of incident cognitive impairment, including Alzheimer's disease and related dementias (ADRD). Dysfunctional metabolic flexibility is increasingly recognized as a critical mechanism linking metabolic risk factors to risk of cognitive impairment, although few studies portable behavioral strategies to enhance metabolic function among individuals at risk for ADRD. The present study will examine the feasibility and acceptability of a 12-week time restricted feeding intervention among individuals with mild cognitive impairment (MCI). Changes in cognitive and metabolic function will also be examined.

Clinical Trial Description

Obese older adults with mild cognitive impairment with mild cognitive impairment will be asked to participate in a 12 week time restricted fasting intervention. Working with a behavioral psychologist, they will adapt the timing their eating patterns to incorporate 2-3 days per week with a 16 hour fasting period, typically lasting from after dinner to lunch the next day. The behavioral intervention will titrate fasting using established behavioral change techniques, with early phase sessions focusing on organizational principles to prepare for weekly fasting scheduling and acceptance-based psychological coping skills, including the ability to tolerate symptoms of hunger and discomfort that may accompany fasting. After treatment initiation, sessions will focus on broadening fasting behaviors for flexible adoption across different contexts and to enhance maintenance of fasting patterns. At baseline and following treatment, participants will undergo tests of cognitive and metabolic function to assess memory, executive function, metabolic flexibility, and inflammation. At both time points, participants will also undergo an abbreviated assessment of cognitive and metabolic function under fasting conditions to assess for any cognitive weaknesses unmasked during periods of brief metabolic 'stress'. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
