What was done
This perspective review describes the mechanistic rationale and current evidence base for the KetoFLEX 12/3 diet, a plant-rich, low-glycemic, mildly ketogenic nutritional framework developed within the ReCODE program for Alzheimer's disease. The diet combines personalized nutritional ketosis (tailored to factors like ApoE genotype and insulin sensitivity) with time-restricted eating (12-hour fast including 3 hours before bed), emphasizing non-starchy vegetables, extra-virgin olive oil, nuts/seeds, and omega-3-rich seafood while limiting refined carbohydrates, sugars, and selected grains and dairy.
What was found
The abstract reports no numerical data, effect sizes, or statistical metrics. It describes mechanistic pathways targeted by the diet (insulin signaling, mitochondrial bioenergetics, neuroinflammation, oxidative stress, autophagy, detoxification, and the gut-brain axis) and notes that observational studies of multimodal ReCODE interventions have reported improvements in cognitive measures, metabolic parameters, mood outcomes, and brain volumetrics.
Why it matters
The paper outlines how combining nutritional ketosis, meal timing, and precision personalization may address metabolic vulnerabilities in neurodegeneration beyond traditional Mediterranean or MIND diets.
Limits
The abstract reports no primary experimental data or quantitative metrics. Evidence to date is limited to mechanistic hypotheses, observational designs, or multimodal interventions in which the specific dietary effects cannot be isolated from concurrent lifestyle components. Randomized controlled trials isolating the KetoFLEX 12/3 diet are lacking.
