““Luckily, human physiology offers one more pathway to power our brains. When food is no longer available, after about three days, the liver begins to use body fat to create those ketones. This is when beta-HBA serves as a highly efficient fuel source for the brain, allowing us to function cognitively for extended periods during food scarcity. Such an alternative fuel source helps reduce our dependence on gluconeogenesis and, therefore, preserves our muscle mass. But more than this, as Harvard Medical School professor George F. Cahill stated, “Recent studies have shown that beta-hydroxybutyrate, the principal ketone, is not just a fuel, but a superfuel, more efficiently producing ATP energy than glucose. It has also protected neuronal cells in tissue cultures against exposure to toxins associated with Alzheimer’s or Parkinson’s.”2””

About This Quote

Source Speech: Interview on Ketogenic Metabolism, Harvard Medical School, 2020

Ketones become an efficient brain fuel during fasting, preserving muscle and protecting neurons, acting as a “superfuel” beyond glucose.

In simple terms: Ketones fuel brain, protect cells, spare muscle when food scarce.

Key Takeaway

Consider ketogenic strategies for cognitive health.
