In this solosode, I walk you through five research topics I've been tracking so you can make smarter, more informed decisions about your health. You'll explore why varying your exercise routine may matter as much as total volume, how toe strength connects to everything from heel pain to sprint power, what plaque composition data reveals that lipid markers alone cannot tell you, how CBN stacks up against CBD and pharmaceutical sleep aids for insomnia, and what a new mouse study suggests GLP-1 drugs are actually doing to lean body mass. I also walk through my own protocols, including my current morning sauna routine, my retatrutide dose, and my go-to CBN sources for travel days.

Mindsip insights from this episode:
Utilize CBN to enhance sleep quality and reduce onset time
A recent study showed a 300mg dose of CBN (Cannabinol) improved sleep quality and reduced sleep onset time in people with insomnia.
Avoid seed oils to prevent fragile arterial plaque
Even if blood tests improve, seed oils high in linoleic acid can make arterial plaque more fragile and likely to rupture.
Avoid heated sunflower, soybean, corn, safflower, cottonseed, and grapeseed oils
To be safe, avoid heated sunflower, soybean, corn, safflower, cottonseed, and grapeseed oils due to their high linoleic acid content.
Clarify GLP-1 impact on muscle versus liver and fat loss
Much of the 'lean mass loss' from GLP-1 drugs is actually from liver mass and intramuscular fat, not contractile muscle tissue.
Strengthen big toe muscles to prevent plantar fasciitis
A weak big toe muscle forces the plantar fascia to absorb excess load, which is a primary cause of plantar fasciitis.
Prioritize big toe strength to prevent falls in older adults
Toe strength is the single best predictor of falling in older adults, making it a crucial but overlooked aspect of fitness.
Incorporate exercise variety to reduce mortality risk
Engaging in a high variety of exercises is linked to a 19% lower risk of premature death, regardless of the intensity.
Utilize micro-dosing of GLP-1 peptide for appetite control during travel
The host uses a micro-dose of the GLP-1 peptide Retatrutide on travel days to suppress appetite and manage gut sensitivity.
