Can a Six Pack Protect Your Brain from Alzheimer’s? | Dr. Oak Sixpack & Josh Helman | #64

Could Building Muscle Help Protect Your Brain?

By Dr. Josh Helman featuring insights from Dr. Oak

What if one of the most powerful tools for preventing Alzheimer’s disease wasn’t found in a prescription bottle — but in the gym?

In this fascinating live in-studio conversation, Dr. Josh Helman sits down with Dr. Oak, also known online as “Dr. Sixpack,” to discuss the surprising connection between muscle, inflammation, metabolism, and brain health.

His message is simple but powerful:

“Stronger muscles may help create a stronger brain”.

And according to Dr. Oak, one of the biggest threats to longevity and cognitive health is something many people never think about:

visceral fat.

Why Visceral Fat Is So Dangerous

Not all body fat is created equal.

Dr. Oak explains that visceral fat — the deep fat stored around internal organs — is one of the body’s most inflammatory tissues.

“Visceral fat is the number one inflammatory organ.”

Years ago, scientists believed fat was simply passive storage tissue. Today, we know it acts like an endocrine organ, releasing inflammatory chemicals throughout the body — including the brain.

That chronic inflammation is increasingly being linked to:

Alzheimer’s disease
Type 2 diabetes
Heart disease
Stroke
Fatty liver disease
Insulin resistance

The good news?

Reducing visceral fat and increasing muscle mass can dramatically improve metabolic health.

Muscle Is More Than Just Strength

One of the most exciting themes from this interview is the idea that muscle itself is medicine.

Dr. Oak explains that skeletal muscle acts as an endocrine organ too, releasing beneficial compounds called myokines, which may help reduce inflammation and improve overall health.

“I tell them to lift weights. That’s my number one recommendation.”

And he doesn’t mean bodybuilding competitions or extreme workouts.

Instead, he focuses on functional strength training:

Squats
Lunges
Deadlifts
Farmer carries
Step-ups
Balance exercises
Resistance training
Bodyweight movements

For older adults especially, maintaining muscle may help reduce the risk of:

Falls
Osteoporosis
Frailty
Insulin resistance
Cognitive decline

Can Exercise Lower Alzheimer’s Risk?

Both doctors strongly believe exercise is one of the most effective Alzheimer’s prevention tools available today.

Dr. Oak emphasizes that movement improves:

Blood flow to the brain
Insulin sensitivity
Sleep quality
Stress levels
Cardiovascular health
Inflammation
Brain plasticity

He encourages people to combine:

Strength Training

At least 2–4 times weekly using safe, progressive resistance.

Cardio

Walking, cycling, swimming, or zone 2 training.

HIIT (High-Intensity Interval Training)

Short bursts of intense activity followed by recovery periods.

Balance & Mobility Work

Especially important as we age.

Why Walking Backward May Help Your Brain and Knees

One of the most unique tips from the interview?

Walking backward.

Dr. Oak recommends backward walking for patients with knee pain because it strengthens the tibialis anterior muscle — a critical muscle for stability and mobility.

But there may also be a brain benefit.

Learning new movement patterns may help stimulate new neural connections and challenge the brain in healthy ways.

He recommends:

Walking backward slowly on a treadmill
Using an incline
Starting very gradually
Staying focused on movement and posture

The Hidden Alzheimer’s Threat: Sugar

According to Dr. Oak, excessive sugar intake is one of the biggest health problems in modern Thailand — and increasingly around the world.

He specifically warns against:

High fructose corn syrup
Sugary coffee drinks
Sweetened teas
Processed beverages

One shocking example:

“The normal dose is 3 tablespoons… 45 grams of just toxin.”

Excess sugar consumption may contribute to:

Fatty liver disease
Insulin resistance
Type 2 diabetes
Obesity
Chronic inflammation
Increased Alzheimer’s risk

This is why some researchers now refer to Alzheimer’s disease as “type 3 diabetes.”

Sleep: One of the Most Important Brain Protectors

Dr. Oak also highlights sleep as a cornerstone of cognitive health.

For one of his patients — a woman with diabetes, fatty liver disease, and an ApoE4 Alzheimer’s risk gene — improving sleep became a major focus of treatment.

Her program included:

Morning sunlight exposure
Blue-light blocking glasses
Meditation
Exercise
Weight loss
Better nutrition
Sauna therapy
Stress reduction

The results were remarkable.

In just two months:

Her A1C dropped from 6.8 to 5.7
She lost nearly 20 pounds
Liver enzymes normalized
Muscle mass increased

This is a powerful reminder that lifestyle changes can profoundly affect metabolic and brain health.

Pollution and Brain Health

Another important topic discussed was air pollution.

Dr. Oak explains that parts of Thailand experience extremely high levels of particulate pollution, partly due to agricultural burning and urban pollution.

Research increasingly links air pollution to:

Neuroinflammation
Cognitive decline
Stroke risk
Alzheimer’s disease

Indoor pollution matters too, including:

Plastics
Paint fumes
Synthetic materials
Mold
Poor ventilation

Reducing toxin exposure may be an important part of protecting long-term brain health.

What About Supplements?

Dr. Oak believes supplements can help — but only after lifestyle foundations are addressed.

His priorities include:

Exercise
Sleep
Stress management
Whole foods
Muscle building
Blood sugar control
Reducing inflammation

Then he may add targeted supplements such as:

Omega-3 fatty acids
Vitamin D
Creatine
B vitamins
Fiber support
TMG (trimethylglycine)

He stresses that supplements should support a healthy lifestyle — not replace one.

The Importance of Personalized Prevention

One of the strongest themes from the discussion is that there is no single perfect diet or protocol for everyone.

Instead, Dr. Oak encourages people to:

Get regular lab testing
Learn their risk factors
Work with knowledgeable practitioners
Experiment safely
Find sustainable habits they actually enjoy

“The key is doing it with joy.”

Because long-term health only works if it’s sustainable.

Final Takeaways From Dr. Oak

If you want to lower your Alzheimer’s risk naturally, Dr. Oak recommends:

Build and maintain muscle
Reduce visceral fat
Walk daily
Lift weights safely
Improve sleep quality
Avoid excessive sugar
Get regular medical checkups
Protect metabolic health
Reduce toxin exposure
Stay physically active for life

And perhaps most importantly:

“Go lift.”

Conclusion:

In this insightful conversation, Dr. Josh Helman and Dr. Oak highlight the powerful connection between muscle health, metabolism, and brain function. Their discussion emphasizes that preventing Alzheimer’s disease is not about finding one magic solution, but about building consistent healthy habits that reduce inflammation and support long-term brain health.From strength training and better sleep to reducing sugar intake and managing stress, the interview reinforces that lifestyle choices play a major role in healthy aging. Dr. Oak especially stresses the importance of building muscle, lowering visceral fat, and staying physically active throughout life.
