The right diet is crucial for prevention and treatment
Some lifestyle changes can prevent and slow cognitive decline for many people. One of those lifestyle changes is diet. The right diet is crucial to preventing and treating cognitive decline.
We recommend a mildly ketogenic diet. That is a diet very low in carbohydrates like grains and sugars. We use the “12/3 Ketoflex Diet” (developed by Dr. Bredesen, of the Bredesen Protocol).
The “12/3” part of this diet refers to the timing of your meals. There should be at least 12 hours between your last meal or snack of the day and the first food you eat the next morning. Also, the last food of the day should be consumed 3 hours before bedtime. This is a kind of intermittent fasting.
If you already know you have the APOE4 gene (which increases your risk of Alzheimer's disease) then a 14-16 hour nighttime fasting interval is going to be better for you.
Intermittent fasting helps your body burn fat for fuel rather than glucose and also helps to improve insulin sensitivity. Both of these changes improve cognition. Consuming your last food of the day 3 hours before sleeping helps to regulate insulin and also improves the balance of several hormones important for cognition.
