Ketogenic Diets Have “Profound Effect on Brain Function,” Studies Find

Brain can’t burn fat for its outsized energy needs. It requires sugar. Or ketone bodies if you decide to starve your body of glucose. Eat lots of fat, consume fewer carbs, and voila. While I’m not overweight I dropped ten pounds in weeks when experimenting with ketosis. Ever since I’ve maintained this weight, not by fasting—a popular ketogenic method is to fast for between 12 and 18 hours every day—but by keeping carb consumption down and fat intake high, also supported by recent research on 135,000 adults.

Studies on Keto

Ketogenic Diet Reduces Midlife Mortality and Improves Memory in Aging Mice

The study shows “that a non-obesogenic ketogenic diet improves survival, memory, and healthspan in aging mice.”

In the first study, mice were fed three diets: zero carbohydrates, a nutrient-balanced diet (the control group), and a high fat diet with just 15 percent carbohydrate intake, a percentage arrived at when researchers slowly added carbs to a carb-restricted diet to find the baseline in which mice remain in ketosis. After 15 percent their bodies suppressed ketosis, and would be little different than the control group.

The mice were put on a cyclic ketogenic, high-fat, or control diet in mid-life. The cycle was one week, so they would eat this way for a week, then every mouse would spend a week on their respective diets. (Ketogenic- and high-fat only mice did not fare as well.) Interestingly, the high-fat group ended up heaviest, though the ketogenic and high-fat groups both had a higher caloric intake than the control group. In terms of longevity, the ketonic group proved most successful, at least through midlife. After thirty months of age, their mortality rate was the same as the control and high-fat groups.

As for memory, the researchers write:

In healthspan testing, we found a striking effect of Cyclic KD [ketogenic diet] on memory as well as more modest effects on a broader range of measures. We saw consistent memory improvement in two distinct tasks over 6 months.

The ketogenic group showed normal cognition wear with aging, but performed better in a visuospatial learning and memory test than the other groups, in which the mice learned to avoid (or not) an electric shock. The KD mice also showed improvement in late middle age (28-30 months) in novel object recognition.

(As one researcher, molecular biologist Eric Verdi )The researchers state that:

“We’re very excited to see such a profound effect on brain function. Our results don’t imply this is going to work in humans. For that, we’ll need extensive clinical trials.”
