Randomized Trials on Saturated Fat

The government is finally catching up to what biohackers have known for decades, and the man helping lead that charge just sat down with Host Dave Asprey to talk longevity science, aging biomarkers, dietary overhaul, AI in medicine, and what a real science-first health agenda actually looks like.

Jim O'Neill served as Deputy Secretary of Health and Human Services and Acting Director of the CDC before being nominated to lead the National Science Foundation in March 2026. Before entering government, he was CEO of SENS Research Foundation, where he led cutting-edge regenerative medicine research targeting mitochondrial mutations, senescent cells, and neocortex rejuvenation. He is a 30-year veteran of health care reform and a genuine longevity insider. 

Dave and Jim cover the complete rewrite of federal dietary guidelines, the government's new randomized controlled trials on saturated fats, and why grains are no longer the core of a "balanced diet." They dig into a 144 million dollar ARPA H program to establish causal aging biomarkers that will unlock real anti-aging drug development and accelerate the kind of longevity research the SENS Foundation pioneered. Jim explains why current aging clocks and DNA methylation markers are not enough, and what comes next for functional medicine, sleep optimization, and metabolism research. They also break down the CDC's return to its infectious disease core, the future of AI in health care, wearable data for disease surveillance, organ bioprinting, GLP-1s, supplements like vitamin D, peptides, and the right to self-experiment. 

You will learn: 

• Why the new federal dietary guidelines finally reject grain-centric nutrition and validate what the biohacking world has argued for 25 years 
• How a 144 million dollar government program aims to build the causal biomarkers that will make real anti-aging and longevity drug development possible 
• What Jim thinks about DNA methylation clocks and why better tools are needed to measure aging and human performance 
• How AI is reshaping prescription refills, clinical decision support, Medicare reimbursement, and the future of functional medicine 
• Why Jim wears an Oura Ring and uses sleep optimization data to make daily health decisions 
• The government's evolving stance on peptides, supplements, and therapies that are not patent protected 
• How organ bioprinting using a patient's own cells could solve the organ shortage crisis 
• What real science replication looks like and why the government is now funding it 
• What the CDC is doing to refocus on infectious disease while shedding mission creep 
• How GLP-1s, fitness tracking, and updated nutrition strategies could significantly cut national obesity rates within five years
