Well Beyond 40

The key to preventing Alzheimer’s begins DECADES before you notice memory problems. 

I’m joined by my longtime friend Dr. David Perlmutter, a board-certified neurologist and bestselling author who has spent decades challenging conventional thinking about brain health. We explore why Alzheimer’s may be less about removing beta amyloid and more about protecting the brain’s immune system through exercise, metabolic health, nutrition, muscle, social connection, and a healthier environment. Most importantly, I want you to walk away knowing that your brain’s future is not something you simply have to accept because your daily choices can help shape how powerfully you age.

 

What you’ll learn:

(04:47) Why the long-standing beta amyloid hypothesis may not fully explain Alzheimer’s disease or lead to meaningful treatment.

(08:07) How microglia act as the brain’s immune cells and can shift between brain-protective and brain-destructive states.

(10:35) Why the biological processes behind cognitive decline may begin decades before noticeable memory problems appear.

(14:00) How maintaining muscle and exercising can support metabolism, mitochondrial function, and the growth and health of brain cells.

(17:50) Which everyday biomarkers, including waist size, blood sugar, insulin, A1C, and blood pressure, can offer clues about brain health.

(21:25) How higher consumption of ultra-processed foods has been associated with substantially greater Alzheimer’s risk in observational research.

(35:48) How inflammation, gut permeability, diet, mitochondria, ketones, and lactate can influence the behavior of the brain’s immune cells.

(46:04) Why air pollution, microplastics, nature exposure, and social connection may all play meaningful roles in protecting the aging brain.

The first few minutes of your morning can shape your focus and mood for the entire day.

I sat down with brain coach and bestselling author Jim Kwik to explore what it really takes to keep your brain strong, focused, and adaptable as you age. We talk about why your brain needs regular challenges just like your muscles do, how your morning inputs can shape the rest of your day, and why outsourcing too much thinking to AI could work against your cognitive health. Most importantly, we break down simple daily choices you can use to strengthen your mind, build trust with yourself, and keep moving toward the person you want to become.

 

What you’ll learn:

(04:02) Jim Kwik shares his childhood story of overcoming a traumatic brain injury and learning to rewire his mind.

(10:05) How cognitive offloading to artificial intelligence can cause human mental muscles to atrophy over time.

(17:39) Why leveraging sleep inertia and attentional priming during your first morning moments frames your focus for the whole day.

(26:32) How neuroplasticity proves your brain is not fixed by age and can continually build new neural pathways.

(31:16) How to implement the "MEDS" framework—Meditation, Exercise, Diet, and Sleep—to support brain hardware.

(41:15) Key brain-boosting foods and how creatine supplementation supports cognitive clarity and offsets jet lag.

(45:34) How to apply the four simple life choices framework to stop feeding habits you do not want.

(01:01:32) How to execute a 10-minute morning elements routine using earth, fire, water, and air for rapid mental refreshment.

The scale is measuring the WRONG thing about how well you’re aging.
I want you to stop looking at the scale as the ultimate measure of how well you're aging and start paying attention to the performance markers that reveal what your body can actually do. In this episode, I break down why grip strength, VO2 max, muscle quality, and mitochondrial health can tell you so much about your future strength, energy, resilience, and independence. I'll also show you how resistance training, protein, recovery, and targeted muscle support can work together to help you build a longer health span and strength span.
What you’ll learn:
(01:42) Why body weight and the scale fail to show how strong, capable, and resilient your body really is.
(02:44) How grip strength can serve as a simple proxy for overall muscle strength and neuromuscular function.
(03:36) Why VO2 max reflects aerobic capacity and is strongly connected with longevity and resilience as you age.
(04:30) How you can measure grip strength and estimate VO2 max using tools like a dynamometer, the Rockport one-mile walk, or a three-minute step test.
(05:12) Why muscle supports metabolism, blood sugar regulation, balance, mobility, independence, and recovery.
(06:04) How health span differs from strength span and why physical capability matters for making your later years worth living.
(07:31) Why mitochondrial function and cellular energy can become limiting factors for muscle strength, endurance, and recovery with age.
(08:17) How urolithin A, mitophagy, resistance training, and protein fit into JJ's muscle-first strategy for aging powerfully.

I’m diving into vitamin C with Dan Pardi, who brings a research-focused perspective to what may be one of the most underestimated nutrients in healthy aging. We explore how absorption changes as you get older, why form and timing matter, and what vitamin C may have to do with exercise adaptation, cellular senescence, brain health, and biological aging. I also get into the practical questions you’re probably asking, including how much to take, when to take it, and how vitamin C might fit into a bigger longevity strategy.
(00:00) How the sodium-dependent vitamin C transporter acts like a turnstile to limit standard ascorbic acid absorption.
(01:14) Why combining liposomal and buffered forms with bioflavonoids maximizes plasma vitamin C retention.
(01:56) How aging drastically decreases nutrient absorption while simultaneously increasing cellular demand and utilization.
(05:03) Why taking high doses of antioxidants too close to resistance training blunts key exercise adaptations.
(06:10) How adrenal and brain accumulation of vitamin C can cause nighttime alertness if taken too late in the day.
(08:48) The essential difference between measuring your accumulated biological age and your current pace of aging.
(10:42) How targeted vitamin C therapy slows cellular senescence and reduces systemic neuroinflammation.
(13:25) The crucial role of vitamin C as a cofactor for two key enzymes that synthesize strong, flexible collagen.

Did you know you can misuse your GLP-1? 
I’m with health optimization pioneer and bestselling author Dr. Jay Campbell to unpack what people are getting right and wrong about GLP-1s and peptides. We explore why these therapies can be about much more than weight loss, including their potential roles in metabolic health, muscle preservation, mitochondrial function, energy, and longevity. Most importantly, we talk about why these powerful tools still need to sit on top of the fundamentals, including protein, resistance training, healthy hormones, quality sleep, and smart metabolic habits.
What you’ll learn:
(04:19) GLP-1 therapies have evolved from early appetite-suppressing medications into newer compounds targeting multiple metabolic pathways.
(06:25) Dr. Jay Campbell believes many people use GLP-1s incorrectly and why protein, hormones, resistance training, sleep, and insulin control matter.
(07:34) Potential benefits of newer GLP-1 therapies beyond appetite suppression, including metabolic efficiency, insulin sensitivity, and changes in compulsive behaviors.
(10:38) JJ and Dr. Campbell distinguish conventional pharmaceutical dosing from the microdosing approach discussed in longevity medicine.
(16:24) Peptide purity and verification matter and what Dr. Campbell believes consumers should look for when evaluating peptide sources.
(26:06) Dr. Campbell break down the peptide and hormone categories he includes in his longevity-focused approach for adults over 45.
(29:54) Mitochondrial compounds including MOTS-c, SS-31, and NAD+ fit into the conversation around energy and healthy aging.
(34:00) Explore the emerging conversation around follistatin-related compounds and their potential role in supporting and preserving skeletal muscle.
