Mindsip insights from this episode:

Utilize DEXA scans for safe and affordable bone density tracking

DEXA scans to measure bone density are inexpensive, widely available (sometimes in mobile vans), and use less radiation than one day's background exposure, making them safe for annual tracking.

Pair carbohydrates with protein for effective muscle synthesis

Consuming carbohydrates with protein, especially post-workout, is crucial to ensure the protein is used for muscle synthesis rather than being burned for energy.

Restrict methionine to enhance longevity

Restricting the amino acid methionine, which is high in animal proteins, has been shown in animal studies to increase longevity by not over-activating the mTOR pathway.

Implement Blueprint's supplement stack for optimal bone health

The Blueprint protocol for bone health includes a specific stack of calcium, magnesium, creatine, vitamins D, B12, B6, K1, K2, various minerals, collagen, and a complete amino acid profile.

Boost walking's bone-building benefits with a weighted vest

A simple way to significantly increase the bone-building impact of walking is to wear a weighted vest or backpack.

Rebuild your skeleton through nutrition and exercise every decade

Your entire skeleton is rebuilt roughly every 10 years, which means you can actively improve your bone mineral density at any age through proper nutrition and exercise.

Measure biomarkers to assess true health

The most reliable way to gauge health is by objectively measuring your body's biomarkers, rather than following charismatic gurus or conflicting popular health narratives.

Understand testosterone reduction in fatherhood for better caregiving

Men consistently show a 23% reduction in testosterone after having children, likely an evolutionary adaptation to promote caregiving over seeking new mates.

Understand dad bod as new visceral fat cell creation, not just expansion

A new study in mice suggests "dad bod" may involve the creation of new visceral fat cells around organs, not just the expansion of existing ones.
