Weekly Wisdom Episode 25 | January 17, 2026

Nutrition, Aging, Metabolism, Movement & Mental Health

This week’s Weekly Wisdom cuts through modern fitness nonsense and exposes the real drivers of health, aging, and performance: energy availability, insulin sensitivity, muscle, movement, sleep, and food quality. If you care about longevity, resilience, and not falling apart in middle age, start here.

Over 50% of Female Athletes Aren’t Eating Enough

Chronic under-fueling isn’t discipline, it’s self-sabotage. Low energy availability destroys hormones, bone density, recovery, and long-term performance. This isn’t a niche issue; it’s epidemic.

I Can Spot Insulin Resistance From Across the Room

Insulin resistance shows up long before blood work does. Body composition, posture, gait, and energy levels all give it away. Metabolic dysfunction is visible if you know what to look for.

What Dies First When You Age

You don’t “age” evenly. Reaction time, balance, power, and muscle quality are usually the first to go. Train the wrong things and decline accelerates. Train the right ones and aging slows dramatically.

69 Years Old But Moves Like He Is 20

This isn’t genetics or luck. It’s movement competency, strength, and consistency over decades. Aging well is trained, not granted.

The Real Reason Your Arteries Are Calcifying

Calcium isn’t the villain. Poor metabolic health, chronic inflammation, and nutrient mismanagement are. This reframes cardiovascular disease away from simplistic cholesterol panic.

Chairs Destroyed Your Body

Excessive sitting quietly dismantles hips, spine, circulation, and neurology. This isn’t about standing desks; it’s about restoring human movement patterns.

Rope Flow

Underrated, scalable, and neurologically rich. Rope flow improves coordination, shoulder health, rhythm, and aerobic capacity without beating you into the ground.

Sleep Is One of Your Best Defenses Against Illness

High-quality sleep significantly reduces susceptibility to common infections. If your sleep is trash, your immune system is negotiating from a position of weakness.

New Dietary Guidelines Quietly Admit They Were Wrong

After decades of damage, institutions are slowly walking back bad advice. The problem: the public still follows it like scripture.

The USDA Finally Got the Food Pyramid Right (South Park Did It First)

Satirical, brutal, and accurate. When cartoons explain nutrition better than government agencies, something has gone very wrong.

Ultra-Processed Food and Mental Health

Mental health isn’t just psychological. Diet quality, metabolic health, and inflammation directly affect mood, cognition, and resilience.

The Greeks Knew Something About Muscle Building We Forgot

Strength, aesthetics, and function were never separate. Muscle wasn’t cosmetic; it was foundational to health, capability, and dignity.

Bottom Line

Modern health collapses when people under-eat, over-sit, under-sleep, and live on ultra-processed food. Strength, movement, muscle, and metabolic health are not optional if you want to age well.

Ignore this at your own risk.
