Studies Raise Questions About Keto's Impact on Liver and Heart Health

For several years, I recommended the ketogenic diet as a way to optimize your metabolic and mitochondrial health. Restricting carbohydrates and shifting the body to rely on fat for fuel seemed, at the time, to be a sound strategy for stabilizing blood sugar and enhancing endurance. Backed by a growing body of published research, it appeared to offer a logical and effective route toward better energy regulation and improved metabolic flexibility.

However, after studying the work of the late Ray Peat, Ph.D., my perspective shifted. His insights into the bioenergetic theory of health revealed how carbohydrate availability is tied to your body’s capacity to sustain healthy energy production. The more I examined his work, the clearer it became that long-term carbohydrate restriction could work against many of the very systems it was meant to support.

Evolution Didn't Design You for Long Life - Can Science Change That?

Human life today is the result of millions of years of evolution, shaped by forces that favored survival and adaptation. You might think that the same process would have extended health and resilience into later life. Yet longevity was not a priority in the evolutionary blueprint, and the result is a body that wears down with age rather than one designed for lasting vitality.

This paradox is the focus of an interview on the Dwarkesh Podcast, featuring Jacob Kimmel, president and co-founder of NewLimit, a biotechnology company developing reprogramming medicines for aging. In their discussion, Kimmel shares his insights into how evolution shaped the limits of human lifespan and what modern science can do to change that trajectory. Learn more: https://bit.ly/4qNiEM0
