结局指标
主要结局
Change in blood ketone levels induced by ketogenic diet
时间窗: Change from baseline serum beta-hydroxybutyrate levels at month 1, 2, 3 (end of ketogenic diet), and 4 (after 1-month washout).
Serum beta-hydroxybutyrate levels will be measured at five monthly study visits; baseline prior to diet initiation, three monthly collections during the ketogenic diet intervention, and after the 1-month washout return to a regular diet.
Proportion of days positive for urinary ketone production
时间窗: Daily for 90 days (the length of the diet intervention)
Participants will measure and report daily urinary ketone status using Ketostix (Bayer, Germany).
次要结局
- Dietary intake characterization prior to and after ketogenic diet initiation(Dietary intake will be collected at Baseline, Month 1, Month 2, Month 3)
- Change in cognitive performance on the Mini-Mental State Exam (MMSE)(Change from baseline global cognitive scores at month 3 (end of ketogenic diet) and change from month 3 global cognitive scores at month 4 (end of 1-month washout).)
- Change in cognitive performance on the Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog)(Change from baseline global cognitive scores at month 3 (end of ketogenic diet) and change from month 3 global cognitive scores at month 4 (end of 1-month washout).)
