Understanding Dietary Fats: The Essential Guide

When it comes to nutrition, few topics have been as controversial as dietary fat. Once vilified as the enemy of health, we now understand that fats play crucial roles in our body's functioning. Let's dive deep into the world of lipids and discover why they're an indispensable part of a healthy diet.

The Fundamentals of Fat

Dietary fat, scientifically known as lipids, is one of the three macronutrients our body needs. At nine calories per gram, it's our most concentrated source of energy, packing more than twice the calories of proteins or carbohydrates. But energy provision is just one of its many vital functions.

Essential Functions of Dietary Fat

• Provides insulation for body temperature regulation
• Supports cell membrane structure and integrity
• Facilitates absorption of fat-soluble vitamins (A, D, E, and K)
• Serves as a precursor for hormone production
• Acts as a protective cushion for vital organs
• Contributes to brain health and function (Fun Fact: The brain is ~60% fat!)

Types of Dietary Fat: Not All Fats Are Created Equal

Understanding the different types of fats is crucial for making informed dietary choices. Each type has unique properties and effects on our health.

1. Saturated Fats

• Solid at room temperature
• Found primarily in animal products and some plant sources
• Stable for cooking at high temperatures

Common Sources: Meat and dairy products, coconut oil, palm oil

While historically demonized, current research suggests the relationship between saturated fat and health is more nuanced than previously thought. The key is moderation and considering the overall dietary pattern. A good goal is to have calories from saturated fat intake account for <10% of daily calories. Saturated fats may contribute to cognitive decline and neuroinflammation so moderation is key.  

2. Unsaturated Fats

These "heart-healthy" fats come in two main varieties:

Monounsaturated Fats

Benefits:

• Lower LDL (bad) cholesterol levels
• Maintain or increase HDL (good) cholesterol
• Provide antioxidants
• Support heart health

Common Sources: Olive oil, avocados, nuts (especially almonds and macadamia nuts), seeds

Polyunsaturated Fats (PUFAs)

These essential fats must come from our diet as our bodies cannot produce them.

Omega-3 Fatty Acids

• Support skin health
• Maintain blood vessel integrity
• Promote organ health
• Reduce inflammation
• Decrease cognitive decline and neuroinflammation

Omega-6 Fatty Acids

• Aid brain development
• Support cognitive function
• Regulate metabolism

The ideal ratio of omega-6 to omega-3 should be around 5-10:1, with approximately 2 grams of omega-3s per day for optimal health.

3. Trans Fats

Trans fats come in two forms:

Natural Trans Fats:

• Found in small amounts in some animal products
• Less concerning from a health perspective

Artificial Trans Fats:

• Created through industrial hydrogenation
• Found in processed foods
• Should be avoided whenever possible

Common Sources to Avoid:

• Processed baked goods
• Microwave popcorn
• Frozen pizzas
• Coffee creamers
• Deep-fried foods

Timing Your Fat Intake

The timing of fat consumption can significantly impact its effects on your body, particularly around exercise:

• Pre-workout: Limit fat intake as it slows digestion and may cause gastrointestinal discomfort
• Post-workout: Include moderate amounts to support recovery and hormone production
• Throughout the day: Space fat intake evenly across meals for steady energy

Practical Guidelines for Fat Consumption

1. Prioritize Quality:
   
   • Choose whole food sources of fat
   • Opt for minimally processed oils
   • Include a variety of fat sources in your diet
2. Balance is Key:
   
   • Include both plant and animal sources
   • Aim for a mix of saturated and unsaturated fats
   • Monitor portion sizes (remember: fats are calorie-dense)
3. Smart Substitutions:
   
   • Replace processed snacks with nuts and seeds
   • Use olive oil instead of butter when appropriate
   • Choose fatty fish over processed meats

Conclusion

Fat is not the dietary villain it was once thought to be. In fact, it's an essential nutrient that plays numerous vital roles in our health. The key is choosing the right types of fats, consuming them in appropriate amounts, and timing them correctly around your activities. By understanding these principles, you can make informed choices about incorporating healthy fats into your diet while supporting your overall health and fitness goals.

Remember: no single nutrient is inherently "good" or "bad" – it's all about context, quantity, and quality. Focus on incorporating a variety of healthy fat sources into a balanced diet that supports your individual needs and goals.

Note: Always consult with a healthcare provider or registered dietitian for personalized nutrition advice, especially if you have specific health conditions or concerns.

Brain Health: How Music and Lifelong Learning Can Prevent Cognitive Decline

In our latest Bionic Health podcast, Dr. Jared Pelo interviews neurologist-turned-entrepreneur Dr. Josh Turknett about the science of brain health, cognitive decline prevention, and how learning complex skills like music can help maintain brain function as we age.

From Neurologist to Music Education Innovator

Dr. Josh Turknett's journey is anything but conventional. After completing medical school and a four-year neurology residency at the University of Florida, he spent years in private practice treating neurological conditions. But over time, he began to recognize a significant gap between what he could offer patients in clinical practice and what he believed they truly needed.

"I came to realize that a lot of the issues I was seeing as a neurologist were related to lifestyle and preventable types of things," Dr. Turknett explains. Through his own experience with migraines, he discovered that dietary changes had a more profound impact on his condition than conventional treatments—a revelation that would eventually lead him to reconsider his entire approach to neurological health.

While still practicing neurology, Dr. Turknett pursued his passion for music, specifically the banjo. Drawing on his background in cognitive neuroscience, he began integrating principles of neuroplasticity into his musical practice. This eventually evolved into BrainJo, an innovative platform that teaches musical instruments through neuroscience-based approaches.

The "Stimulate and Support" Framework for Brain Health

When it comes to maintaining cognitive health, Dr. Turknett advocates a simple yet powerful framework: stimulate and support.

"There are two things to think about in terms of keeping a healthy brain throughout our life," he says. "We have stimulation on one side and support on the other side."

Stimulation: Fighting Autopilot Mode

Cognitive stimulation is essential for maintaining brain health, but Dr. Turknett points out that many of us, especially in established careers, operate largely on autopilot. "The more you can spend your day on autopilot, the less cognitive stimulation you've provided," he explains.

Real cognitive stimulation comes from activities that trigger plastic reorganization in the brain—essentially, learning new knowledge and skills. This is where complex activities like learning a musical instrument come in.

BrainJo currently offers instruction in multiple instruments:

• Two styles of banjo (claw hammer and fingerstyle)
• Piano
• Ukulele
• Fiddle
• With guitar coming soon

Support: Giving Your Brain What It Needs

Just as important as stimulation is providing your brain with the resources it needs to maintain existing neural connections and build new ones. Dr. Turknett identifies several key pillars of brain support:

1. Physical activity - Particularly activities that combine cardiovascular fitness, strength training, and cognitive demands (like tennis or pickleball)
2. Sleep and rest - Critical for neural recovery and consolidation
3. Nutrition - Including key nutrients like B12, vitamin D, magnesium, zinc, and copper
4. Stress management - Limiting chronic stress that can damage brain tissue
5. Social connection - Perhaps the most underappreciated factor in brain health

On the often-overlooked importance of social interaction, Dr. Turknett notes: "Being around other people, conversing with other people, being in social situations is an enormous cognitive stimulus... one of the reasons that we see [cognitive] deterioration is because of the loss of that stimulus when people are isolated."

Assessing Cognitive Risk and Monitoring Brain Health

Many people, especially those with family histories of dementia or genetic risk factors like APOE4, wonder how to assess their risk for cognitive decline. Dr. Turknett emphasizes that while there's no single test that can definitively predict risk, there are several approaches to monitoring brain health:

• Regular cognitive assessments, whether through formal testing or self-monitoring
• Basic blood work to identify conditions like metabolic syndrome or nutritional deficiencies
• Lifestyle evaluation to identify areas for improvement

He recommends foodforthebrain.org for those interested in comprehensive cognitive evaluation with a nutritional focus.

Rather than viewing cognitive health as predetermined, Dr. Turknett stresses that "we are actively influencing our risk all the time." This empowering perspective frames brain health as something we can continuously improve through our daily choices.

Anyone Can Play Music: The Science of Learning at Any Age

Dr. Turknett's new book, "Anyone Can Play Music: How to Realize Your Musical Potential with the Laws of BrainJo," challenges the common belief that learning complex skills like music becomes impossible as we age.

"The reason we can learn anything at any age is because we have this ability to change the brain at any age," he explains. "Learning complex skills relies on neurological mechanisms that we all share."

The book outlines principles for leveraging these natural mechanisms, often requiring readers to unlearn ineffective approaches taught in traditional education. It's as much about how to learn anything as it is about music specifically.

A Prescription for Brain Health

For someone in their mid-40s concerned about future cognitive health, Dr. Turknett recommends:

1. Evaluate your current cognitive stimulation - Is your work challenging your brain, or are you on autopilot?
2. Incorporate complex real-world skills - Music, dance, or sports that demand coordination and strategy
3. Ensure physical fitness - Combining low-level movement, resistance training, and occasional high-intensity exercise
4. Monitor nutritional status - Particularly for B12, vitamin D, and other brain-essential nutrients
5. Prioritize social connection - Ideally through activities that simultaneously provide cognitive stimulation

The key is finding activities you enjoy that provide both cognitive challenges and social connection—like joining a community of musicians or picking up a sport like pickleball that combines physical activity, strategy, and social interaction.

Beyond the Clinic: Making a Broader Impact

Dr. Turknett's transition from clinical practice to entrepreneurship reflects his desire to have a greater impact on brain health than the constraints of a traditional medical practice would allow.

"To actually fulfill the role that I initially signed up for... I could do a much better job doing what I'm doing now than I could in the clinic," he reflects. Through his online platform, books, and educational content, he's able to reach and help far more people than would be possible seeing patients one at a time.

This sentiment resonates with Dr. Pelo, who made a similar transition from emergency medicine to focusing on preventative health through technology. Both physicians recognize that while there will always be a need for excellent clinicians, there's also tremendous value in creating scalable approaches to health that can benefit millions.

Understanding Your Metabolism: More Than Just Burning Calories

Ever wondered why some people seem to eat whatever they want while others gain weight just looking at food? The answer lies in understanding metabolism - your body's complex system for converting food into energy. Let's break down the science into digestible pieces.

The Building Blocks of Metabolism

Basal Metabolic Rate (BMR)

Think of BMR as your body's pilot light - it's the energy you need just to exist. Even if you spent all day binge-watching your favorite shows without moving, your body would still burn these calories to:

• Keep breathing
• Produce hormones
• Grow and repair cells
• Keep your heart beating

Resting Metabolic Rate (RMR)

RMR is like BMR's close cousin - it measures similar things but under slightly different conditions. The main difference? RMR can be directly or indirectly measured while at rest and is influenced by recent activity and meals. For practical purposes, they're nearly identical (only 10-20% difference).

Your Daily Energy Breakdown

Here's how your body uses energy throughout the day:

BMR: The Heavy Lifter (60-70%)

• The majority of your daily calories go toward basic survival functions
• This is why crash diets that drop below BMR are so dangerous

Thermic Effect of Food (TEF) (10-15%)

• Yes, you burn calories digesting food!
• Different foods require different amounts of energy to process:
  
  • Protein: Burns 20-30% of its calories during digestion
  • Carbs: Burns 5-10%
  • Fats: Burns just 0-3%

Exercise Activity (EAT) (5-10%)

• Calories burned during your workouts
• High-intensity exercise creates a longer "afterburn" effect
• More intense workouts = longer metabolic boost

Non-Exercise Activity (NEAT) (5-10%)

• The fidgeting, thinking, and random movements you do all day
• Can vary significantly between individuals
• Often decreases during dieting (you naturally move less as your body attempts to limit calorie burn, being in a deficit)

Smart Weight Loss: Working With Your Metabolism

Want to lose weight without wrecking your metabolism? Here's the smart approach:

1. Never eat below your BMR - it's like trying to drive a car without enough gas
2. Calculate your target calories:
   Daily Calories = (BMR × Activity Factor) - 250
3. Aim to lose 0.5-1 pounds per week (anything faster usually backfires)

The Calorie Quality Question

Not all calories are created equal. Here's why the type of food matters:

Protein: The Metabolic MVP

• Burns the most calories during digestion
• Increases overall energy expenditure
• Helps preserve muscle during weight loss
• Keeps you feeling fuller, longer

Carbohydrates: Choose Wisely

• Complex carbs require more energy to digest
• Simple sugars are "metabolically lazy" and digest quickly, great for a workout but not at rest
• Quality matters as much as quantity

Fats: Essential but Efficient

• Burn very few calories during digestion
• Important for hormones and health
• A little goes a long way

Practical Takeaways

1. Focus on protein - it's your metabolism's best friend
2. Don't crash diet - it's like putting your metabolism in hibernation and most people gain back all the lost weight and more once they end
3. Stay active - both planned exercise and daily movement matter
4. Choose complex carbs over simple sugars
5. Remember that healthy weight loss is a marathon, not a sprint

Your metabolism isn't just a simple calorie counter - it's a complex system that responds to how you eat and move. By understanding how it works, you can make better choices that support your goals while keeping your body's engine running smoothly.

Remember: The best approach to managing your metabolism is one that you can maintain long-term. Quick fixes might work temporarily, but they often lead to metabolic adaptations that make maintaining weight loss harder in the future.

Aging Skin & Rejuvenation: Insights from Dr. Jennifer Goldwasser

In a recent Medicine 3.0 episode, Dr. Catherine Isaac welcomed back dermatologist Dr. Jennifer Goldwasser to discuss aging skin and rejuvenation strategies. This informative conversation covered everything from basic skin care to advanced treatments, offering valuable insights for anyone looking to maintain healthy skin as they age.

Understanding Skin Changes with Age

Dr. Goldwasser explains that as we age, our skin undergoes numerous changes:

• Mottled, non-uniform coloration
• Increased laxity
• Development of wrinkles
• Growth of various skin spots

Sun exposure is the primary culprit behind these changes. Dr. Goldwasser suggests comparing protected skin (like the underside of your arm) with frequently exposed areas to see the dramatic difference sun damage causes. Another telling sign of sun damage in elderly individuals is "senile purpura" - red-purple blotches that appear on sun-exposed skin due to deteriorated connective tissue.

The Subtraction-First Approach

Rather than immediately adding products, Dr. Goldwasser advocates for a "subtraction-first" approach to skin care:

1. Eliminate harmful habits:
   • Tobacco use (smoking, vaping)
   • Excessive alcohol consumption
   • Recreational drugs
   • Sun exposure
   • Ultra-processed and animal-based foods
2. Add beneficial practices:
   • Plant-based diet rich in phytonutrients and antioxidants
   • Simple, targeted skin care routine

Essential Skin Care Elements

1. Gentle Cleansing

Dr. Goldwasser recommends gentle cleansers like Dove sensitive skin products or La Roche Posay's hydrating cleanser. She warns against products with strong fragrances, dyes, or exfoliating particles, especially for aging skin which becomes thinner and more sensitive.

2. Proper Moisturizing

• Choose the right vehicle: Creams (oil-based) are better for aging skin than lotions (water-based)
• Look for jar packaging rather than pump tops for richer products
• Recommendations: Vanicream, La Roche-Posay Lipicar, CeraVe or Cetaphil in jars
• For extremely dry areas, Dr. Goldwasser surprisingly recommends Crisco shortening as an effective, non-irritating option

3. Sun Protection

Sun protection remains crucial even as we age, as UV damage continues to accumulate.

Managing Common Skin Conditions

Seborrheic Dermatitis

Often mistaken for dry skin, seborrheic dermatitis (dandruff) requires:

• Regular, vigorous cleansing
• Products containing pyrithione zinc (like Head & Shoulders)
• For facial involvement: washing twice daily, once with anti-dandruff shampoo and once with facial cleanser

Dr. Goldwasser notes that seborrheic dermatitis is common in babies and aging adults, particularly those with neurological conditions like Parkinson's disease or those experiencing immunosuppression.

Anti-Aging Treatments

Over-the-Counter Options

1. Retinols: Derived from vitamin A, these are the most potent OTC anti-aging ingredients
   • Benefits: Reduce fine lines, improve skin texture
   • Limitations: Can be irritating and sun-sensitizing
2. Vitamin C:
   • Benefits: Stimulates collagen production, acts as an antioxidant
   • Limitations: Unstable in formulations, effective products are costly
3. Other Options:
   • Peptides
   • Hyaluronic acid for moisture
   • Niacinamide for inflammation

Prescription Treatments

Tretinoin (prescription retinoid):

• Apply a pea-sized amount at night
• Wait at least 20 minutes after washing
• Avoid sensitive areas (upper eyelids, lips)
• May need to start gradually (every other day) or seasonally
• Most effective for fine lines, less so for deep wrinkles or skin laxity

Professional Procedures

1. Botox:
   • Temporarily paralyzes muscles to reduce expression lines
   • Generally safe with effects lasting 3-4 months
   • Best for forehead lines and "11 lines" between brows
2. Fillers:
   • Typically hyaluronic acid-based (Restylane, Juvederm)
   • Best for deeper lines around the mouth
   • Duration varies based on product
3. Lasers and Energy Devices:
   • Can address pigmentation, visible vessels, and redness
   • Newer technologies like radiofrequency microneedling can stimulate collagen and tighten skin
4. Surgical Options:
   • Most effective for significant laxity
   • Eyelid surgery (blepharoplasty) offers good value and high satisfaction

Emerging Treatments

While Dr. Goldwasser finds radiofrequency microneedling promising, she cautions against jumping on trends without sufficient evidence:

• Red light therapy: Limited scientific support
• Topical estrogen: Insufficient safety and efficacy data

Key Takeaways

1. Protect skin from sun damage at every age
2. Simplify your routine - less is often more
3. Choose products appropriate for your skin's changing needs
4. Adjust skin care seasonally and as you age
5. Consider the risk-benefit ratio before trying trendy treatments

The podcast emphasizes that good skin care requires adapting to our body's changing needs with age, replacing dated routines, and focusing on evidence-based approaches rather than marketing claims.

Nutrient Timing: A No-Nonsense Guide to Fueling Your Workouts

Let's talk about nutrient timing - your secret weapon for better workouts and faster recovery. Think of it as a GPS for your nutrition: right food, right time, better results. Here's everything you need to know about eating around your workouts.

The Basics: Protein Throughout Your Day

Getting your protein right is like building blocks for success:

• Aim for 20-40g protein every 3-4 hours (that's about 0.25-0.40g per kg of body weight)
• Choose quality protein sources - your body will thank you
• This steady protein flow keeps your muscles happy and recovery strong for optimal muscle protein synthesis

Remember: Your needs might vary based on your age, fitness level, and goals Consult a dietitian or your Bionic Advisor!

Strategic Meal Timing Guidelines

Pre-Exercise Nutrition (3-4 Hours Before)

Key Objectives: Minimize gastrointestinal distress, provide sustained energy and support performance. This can be adjusted for different eating schedules (e.g., intermittent fasting), though carbohydrates are recommended before endurance training.

Think of this as laying your workout foundation:

• Go for foods that won't upset your stomach (low GI is your friend)
• Easy on the fiber - now's not the time for that extra-fibrous cereal
• Balance is key: plenty of carbs, light on fats, moderate protein

Try This: A bowl of Greek yogurt topped with berries and a sprinkle of granola. Simple, effective, delicious.

Immediate Pre-Exercise (15-60 Minutes Before)

Focus Areas: Easy digestion, quick energy availability, performance support

Quick energy time:

• Choose easily digestible carbs - they're your immediate fuel
• A little protein goes a long way
• Consider caffeine if it's your thing - it can help spare glycogen and boost performance

Perfect Snack: A banana with a bit of peanut butter or a couple of rice cakes with honey.

Intra-Workout Nutrition (During Exercise):

For those longer sessions (60+ minutes):

• Fuel up with 30-60g carbs per hour
• Sip on a sports drink (aim for 6-8% carb solution)
• Take 6-12 oz every 10-15 minutes

Go-To Options: Sports drinks, energy gels, or even some dried fruit or banana.

Immediate Post-Exercise (0-2 Hours After)

Primary Goals: Trigger insulin release, facilitate carbohydrate storage, support muscle repair, This is your golden opportunity for recovery:

• Quick-digesting carbs are your friends
• Pair them with protein for the perfect recovery combo (2:1 Carb: Protein Ratio)
• If you've been sweating buckets, get 12-16 oz of fluid with those carbs per lb lost

Example: Try a turkey and hummus wrap on whole wheat with some fresh veggies, or keep it classic with chocolate milk, a classic post-workout option that provides carbohydrates and protein for muscle recovery and glycogen replenishment.

Extended Post-Exercise (2+ Hours After)

Recovery Objectives: Transition to anabolic state, accelerate waste elimination, replenish glycogen stores, support muscle repair and growth, strengthen immune system

Now we're talking proper recovery:

• Focus on quality whole foods
• Keep those carbs flowing, especially after long distance endurance work
• Match your intake to how hard you worked

Perfect Plate: Grilled salmon with a sweet potato and some steamed broccoli for a balanced combination of protein, carbohydrates, and vegetables for recovery.

Pre-Bedtime Nutrition Strategies

If you’d like to incorporate a post-dinner snack, end your day right:

• Aim for 30-40g of slow-digesting (casein) protein
• Add some complex carbohydrates for good measure
• Skip the sugary stuff - your sleep is precious

Benefits include: enhanced protein synthesis for muscle growth, increased overnight metabolic rate (burning more calories at rest!), and supported recovery.

Bedtime Snacks:

• Hard-boiled eggs with a slice of whole grain toast
• Cottage cheese or Greek yogurt with berries for the sweet tooth

The Bottom Line

Think of nutrient timing like seasoning your food - it can make a good thing great, but it won't fix a bad recipe. Focus first on eating quality foods consistently, then dial in your timing to level up your results.

Remember: These aren't rigid rules - they're guidelines to help you perform your best. Experiment, adjust, and find what works for your body and schedule. The best nutrition plan is the one you can stick to consistently.

Food Environment and Meal Prep: Driving Nutrition Success

In this episode of Medicine 3.0, host Kelly interviews Bionic Health Advisor Anna Simmons to discuss practical nutrition strategies that can help anyone achieve their health goals. They dive into the differences between meal prepping and batch cooking, how to optimize your food environment, and provide actionable tips for grocery shopping and maintaining consistency despite busy schedules.

Topics Covered

• Meal prep vs. batch prep techniques and benefits
• Food environment optimization
• Creating sustainable nutrition plans
• Grocery shopping strategies
• Solutions for busy schedules
• Protein distribution throughout the day
• Beginner-friendly approaches to meal planning

Main Takeaways

The Power of Preparation

Both Kelly and Anna emphasize that preparation is key to nutritional success. Whether you choose meal prepping (preparing complete, portioned meals) or batch prepping (cooking larger quantities of individual ingredients), the upfront time investment significantly reduces daily decision-making and cooking time throughout the week.

"Preparation decreases decision fatigue. Throughout the week, you don't have to decide what you want to eat. It's already prepared for you. You know you have a healthy option to reach for." - Anna

Optimize Your Food Environment

Small changes to your kitchen and food storage can have substantial impacts on your nutrition:

• Replace candy bowls with fruit on counters
• Store less healthy options in opaque containers or away from eye-level
• Position colorful fruits and vegetables prominently in your fridge

Strategic Protein Distribution

Rather than following the typical American pattern of minimal protein at breakfast and excess at dinner, both advisors recommend distributing protein more evenly throughout the day. Aiming for approximately 30 grams of protein at each meal can help with muscle maintenance, satiety, and energy levels.

Smart Grocery Shopping

Before even beginning to meal prep, having a grocery strategy sets you up for success:

• Create a shopping list based on planned meals
• Shop the perimeter of the store for nutrient-dense options
• Take inventory of your fridge and pantry before shopping
• Be flexible with ingredients if certain items don't look fresh

Freezer as Your Friend

For busy individuals, the freezer becomes an essential tool:

• Freeze pre-portioned meals for busy weeks
• Prepare freezer-ready smoothie packs
• Stock up on frozen vegetables and fruits, which are often flash-frozen at peak ripeness
• Make breakfast burritos or sandwiches that can be quickly reheated

Progress Isn't Linear

Both advisors emphasize that nutritional progress doesn't follow a straight line. There will be weeks when meal prepping isn't possible, and that's okay. What matters is returning to consistent habits:

"Progress is not linear. You may have seen a graph in the past where there's what people think progress is and then what it actually is and it's just squiggly lines all over." - Kelly

Start Small and Simple

For beginners, Anna recommends:

• Keep recipes simple rather than attempting complex dishes
• Focus on spices, seasonings, and sauces for variety
• Start with small, achievable goals like improving just breakfast
• Break down larger nutrition goals into manageable steps
• Consider working with a coach or knowledgeable friend for accountability

Beyond Traditional Cardiology: Inside Bionic Health's Advanced Vascular Module

Cardiovascular disease remains the leading cause of death globally, yet traditional healthcare often takes a reactive rather than preventive approach. At Bionic Health, we're changing this paradigm with our comprehensive Vascular Module, designed to identify cardiovascular risk factors years—even decades—before they manifest as clinical problems.

In a recent podcast conversation between Bionic Advisor Kelly Joniak and physician Dr. Catherine Isaac, we explored the science and strategy behind our vascular assessments. Here's what makes our approach different.

Beyond Basic Cholesterol Testing

Most primary care visits include a standard lipid panel measuring total cholesterol, HDL, LDL, and triglycerides. While these metrics provide baseline information, they tell only part of the story. Our Vascular Module includes advanced biomarkers that offer deeper insights:

• Apolipoprotein B (ApoB): This carrier protein reflects the actual number of LDL particles circulating in your bloodstream. Dr. Isaac explains, "APO-B is a reflection of how many LDL cholesterol particles are migrating through your bloodstream... the more congested it is, the greater likelihood that particles will embed in the arterial wall."
• Lipoprotein(a): This genetically determined particle increases plaque buildup risk approximately sixfold. "Those particles are six times more likely to promote plaque buildup," notes Dr. Isaac.
• Inflammatory Markers: We measure high-sensitivity CRP, IL-6, and homocysteine levels, which can indicate cardiovascular inflammation.

Seeing What's Actually Happening in Your Arteries

Rather than relying solely on blood tests, we use advanced imaging to visualize arterial health directly:

• Coronary Artery Calcium (CAC) Scoring: This non-invasive CT scan quantifies calcified plaque in the coronary arteries, providing a concrete measure of existing disease.
• Coronary CT Angiogram: For some members, this more detailed scan using contrast dye visualizes both calcified and soft plaque, offering comprehensive assessment of arterial narrowing.

"Atherosclerosis is a lifelong process that takes decades to develop," Dr. Isaac points out. "When plaque is initially laid down, it's soft. But over time, as your body remodels it, it calcifies and hardens."

Personalized Treatment Through Deeper Testing

One of the most valuable components of our Vascular Module is the Cholesterol Balance Test, which determines whether a member predominantly produces cholesterol internally or absorbs it from the intestine. This distinction directly informs treatment approaches:

• High Absorbers: May respond better to medications like ezetimibe that block intestinal cholesterol absorption.
• High Producers: Typically see significant benefits from statins, which inhibit internal cholesterol production.

Additionally, our Fatty Acid Balance Test measures the ratio of omega-3 to other fats in red blood cell membranes. "An ideal omega-3 index would be greater than eight," explains Dr. Isaac. "Most people eating an American diet have a very low omega-3 index because they're not getting significant sources of fish."

Moving Beyond Fear-Based Medicine

Dr. Isaac addresses common misconceptions about cardiovascular interventions, particularly statins. "One of the big components of my job is dispelling myths around statins. A lot of people reflexively balk at the idea of having to take a medication on a daily basis."

By using personalized data rather than one-size-fits-all approaches, we can make informed recommendations that balance risk and benefit for each individual.

The Hierarchy of Cardiovascular Interventions

While we employ advanced testing and personalized medicine, we emphasize that the foundation of cardiovascular health remains lifestyle-focused:

1. Food First Approach: We recommend the "800-gram diet"—consuming approximately six cups of fruits and vegetables daily. "Eating more fruits and vegetables is associated with lower blood pressure, lower cardiovascular risk, lower risk of diabetes, lower risk of cancers, lower risk of all-cause mortality," says Dr. Isaac.
2. Regular Physical Activity: Consistent cardiovascular exercise significantly improves vascular health markers.
3. Targeted Medications When Appropriate: For those with elevated risk profiles, evidence-based medications can dramatically reduce risk. "A person with an extremely strict diet can reduce their LDL cholesterol by approximately 20 to 25 percent," notes Dr. Isaac. "But with statins, we can dramatically drop people's LDL cholesterol and ApoB by 30 to 40 percent."
4. Targeted Supplementation: Supplements like omega-3s can fine-tune a cardiovascular approach, but they're the "cherry on top" rather than the foundation.

The Bionic Difference: Proactive, Not Reactive

Perhaps most importantly, our Vascular Module embodies our core philosophy: identify and address health issues before they become problems.

"Coming from traditional medicine, we were really playing catch-up more of the time than being proactive," reflects Dr. Isaac. "I get a lot of gratification out of taking care of our members, identifying disease earlier than we would have normally identified it using the traditional approach."

By combining advanced diagnostics, personalized interventions, and evidence-based lifestyle modifications, we're redefining what vascular health assessment can be—and helping our members live longer, healthier lives in the process.

Carbohydrates: Your Body's Preferred Energy Source

Carbohydrates often get a bad rap in popular diet culture, but this macronutrient powers everything from your daily activities to high-intensity workouts. Let's explore why carbohydrates are essential and how to make them work for your health and fitness goals.

‍What Are Carbohydrates?

At their most basic level, carbohydrates are compounds made up of carbon, hydrogen, and oxygen.They are an important fuel source that powers vital bodily functions and physical activities. They also help spare protein and fats and assist with the breakdown of lipids. Like protein, carbohydrates contain four calories per gram.

The Three Main Types of Carbohydrates

1. Simple Carbohydrates (Sugars)

Simple carbohydrates consist of one or two sugar molecules and are quickly digested and absorbed. They're your body's version of "quick-start" energy—particularly useful before exercise when you need rapid fuel.

Monosaccharides (Single Sugar Molecules):

• Glucose: Found in grains, starchy vegetables, and fruits
• Fructose: Present in fruits, honey, and high fructose corn syrup
• Galactose: Found in dairy products

Disaccharides (Two Sugar Molecules):

• Sucrose (table sugar): glucose + fructose
• Lactose (milk sugar): glucose + galactose
• Maltose (malt sugar): glucose + glucose

2. Complex Carbohydrates

Complex carbohydrates feature longer chains of sugar molecules, providing sustained energy release (think slow-burning coals rather than quick-flaming kindling) and typically offering more nutritional benefits.

Two Main Forms:

• Starch: Found in:
  
  • Grains (wheat, rice, oats)
  • Legumes (beans, lentils, chickpeas)
  • Starchy vegetables (potatoes, corn, peas)
• Glycogen: Your body's storage form of carbohydrates, found in liver (~100g) and muscle tissue (~300-500g). This is formed by many molecules of glucose linked together.

3. Dietary Fiber

Fiber is the rebel of carbohydrates—your body can't digest it, but it plays crucial roles in your health. High-fiber diets promote comprehensive wellness by supporting heart health through cholesterol reduction, enhancing the gut microbiome, and aiding weight management by increasing satiety, stabilizing blood sugar, and reducing caloric density.

Combined with adequate protein, fiber creates a more sustainable approach to nutrition and weight control.

Types of Fiber:

• Soluble Fiber:
  
  • Dissolves in water
  • Forms a gel-like substance during digestion
  • Found in oats, barley, legumes, and certain fruits and vegetables
  • Helps regulate blood sugar and cholesterol levels
• Insoluble Fiber:
  
  • Doesn't dissolve in water
  • Adds bulk to stool
  • Found in whole grains, nuts, seeds, and fruit/vegetable skins
  • Promotes regular bowel movements

How much is enough? Per day, the recommended intakes are at least 25g for women and 38g for men.

Carbohydrates and Exercise Performance

Carbohydrates are essential for exercise performance, regardless of whether your goal is weight loss, muscle gain, or improved endurance. Here's why:

Energy Systems and Carbohydrate Use

Your body prioritizes different energy systems depending on exercise type and intensity:

• Anaerobic System: Used during high-intensity, short-duration activities
• Aerobic System: Primary system for longer-duration activities

Both systems can utilize carbohydrates as fuel, particularly during high-intensity exercise. Your body stores carbohydrates as glycogen, providing enough energy for approximately 90 minutes of sustained activity before depletion—it's like your internal energy reserve that needs regular replenishing! Have you ever heard of runners “hitting a wall” or “bonking”? That is an indication that glycogen stores have been depleted!

Daily Carbohydrate Recommendations Based on Activity Level

To optimize your performance and recovery, adjust your carbohydrate intake based on your activity level and goals. Research published in the Journal of the International Society of Sports Nutrition provides clear guidelines for athletes at various training levels (Kerksick et al., 2017):

Minimally Active (Less than 3 hours/week): 2-3g per kg body mass

Lightly Active (3-5 hours/week): 4-5g per kg body mass

Moderately Active (10 hours/week): 6-7g per kg body mass

Professional/Elite (20+ hours/week): 7+ g per kg body mass

Endurance/Ultra (Event-specific): 7-12g per kg body mass

Making Smart Carbohydrate Choices

Not all carbs wear capes, but the good ones might as well! Focus on whole, minimally processed carbohydrate sources:

• Whole grains
• Fresh fruits and vegetables
• Legumes and beans
• Starchy vegetables

These foods provide not just carbohydrates but also:

• Essential vitamins and minerals
• Dietary fiber
• Beneficial phytonutrients
• Sustained energy release

Timing Your Carbohydrate Intake

Strategic timing of carbohydrate consumption can optimize your energy levels and exercise performance—think of it as delivering the right fuel at exactly the right moment:

Before Exercise:

• Simple carbs for quick energy
• Timing depends on individual tolerance

During Exercise:

• Necessary for sessions longer than 90 minutes
• Easy-to-digest forms preferred

After Exercise:

• Replenish glycogen stores
• Combine with protein for optimal recovery

Conclusion

Carbohydrates are more than just calories – they're your body's preferred energy currency that powers both your daily activities and athletic performance. By understanding the different types of carbohydrates and how to time them effectively, you can optimize your nutrition to support your health and fitness goals.

Remember that individual needs vary based on activity level, goals, and personal tolerance. Consider working with a registered dietitian to determine the optimal carbohydrate intake for your specific situation.

Understanding Female Hormone Health: A Conversation with Dr. Catherine Isaac

In the latest episode of Medicine 3.0, Dr. Catherine Isaac joins Kelly Joniak to discuss Bionic Health's female hormone module, offering insights into hormone testing and treatment options across different life stages. This comprehensive discussion breaks down complex medical concepts into actionable information for women seeking to understand and optimize their hormonal health.

Understanding the Different Life Stages

Dr. Isaac explains the three key stages of female hormonal transitions:

- Premenopausal: The period when a woman experiences regular menstruation

- Perimenopausal: A transitional phase where hormone levels fluctuate unpredictably

- Postmenopausal: Defined as 12 months after the final menstrual period

When to Consider Hormone Testing

The female hormone module isn't a one-size-fits-all solution. Dr. Isaac emphasizes that hormone testing is most beneficial for specific situations:

For premenopausal women:

- Irregular or absent periods

- Evaluation of conditions like hypothalamic amenorrhea

- Assessment of PCOS (polycystic ovarian syndrome)

For perimenopausal women:

- Confirming perimenopause status

- Evaluating symptoms like hot flashes, sleep disruption, and mood changes

- Understanding hormone levels during the transition

Important note: Hormone testing isn't useful for women on birth control, as it can interfere with natural hormone measurements.

The Bionic Approach to Treatment

Bionic Health takes a personalized approach to hormone therapy, considering each person's unique symptoms and medical history. Treatment recommendations focus on FDA-approved indications, including:

- Moderate to severe hot flashes

- Prevention of osteoporosis in high-risk patients

- Management of early-onset menopause

- Treatment of genitourinary symptoms

Benefits of Hormone Therapy

When appropriately prescribed, hormone therapy can offer several benefits:

- Relief from menopausal symptoms

- Improved sleep quality

- Better bone health

- Enhanced intimate wellness

- Prevention of age-related bone loss

Lifestyle Considerations During Hormonal Transitions

Dr. Isaac and Kelly discuss important lifestyle modifications that can support hormonal health:

Exercise Recommendations

- Focus on strength training

- Incorporate high-intensity interval training

- Work with qualified professionals for proper form and progression

- Take a gradual approach to prevent injury

Nutrition and Weight Management

- Be mindful of body composition changes

- Focus on quality nutrition

- Reduce simple carbohydrates and saturated fats

- Support muscle building through proper nutrition

Understanding the Risks

Dr. Isaac emphasizes the importance of timing and individual risk assessment:

- Best results when started within 10 years of menopause

- Different delivery methods carry different risks

- Consideration of personal and family medical history

- Regular monitoring and adjustment of treatment plans

The Role of Progesterone

For women with an intact uterus, progesterone is a crucial component of hormone therapy:

- Prevents uterine lining overgrowth

- Can improve sleep quality

- May affect mood in some women

- Alternative options available if needed

The Bionic Difference

At Bionic Health, hormone therapy isn't prescribed without careful consideration. The process includes: Comprehensive baseline evaluation, targeted testing based on symptoms and needs, regular monitoring and adjustment ,an consideration of alternative treatments when appropriate
