Cardiovascular Health

Cardiovascular health plays a critical role in overall longevity and reducing the risk of diseases like heart attacks, strokes, and dementia. Key markers and proactive steps can help maintain a healthy cardiovascular system and mitigate long-term risks.

Key Cardiovascular Tests

ApoB Test: This test measures apolipoprotein B (ApoB), a protein that is closely linked to cardiovascular disease risk. Monitoring ApoB levels helps in assessing heart health and potential risks.
LP(a) Test: Elevated levels of lipoprotein(a) [LP(a)] are a prevalent hereditary risk factor for heart disease. Testing for LP(a) once in your lifetime is important to identify genetic risk early on. -> Do a test at least once in your lifetime !
Calcium Scan: A calcium scan measures the buildup of calcified plaque in your arteries, helping to detect early signs of heart disease.

LDL-C and Cardiovascular Risk

LDL-C (Low-Density Lipoprotein Cholesterol): Keeping LDL-C levels within the range of 10-20 mg/dL is essential for reducing cardiovascular risk. The lower, the better, as high LDL-C levels are associated with a higher likelihood of heart disease.
Lowering LDL-C: The most effective pharmaceutical approach to lowering LDL-C is through a combination of statins and PCSK9 inhibitors, which significantly reduce ApoB levels and cardiovascular risk.

Metabolic Health and Cardiovascular Disease

Metabolic Factors: Metabolic health markers such as insulin levels, visceral fat, homocysteine, and amino acids are strongly associated with an increased risk of heart attacks, strokes, and dementia. Poor metabolic health is a major contributor to cardiovascular disease.
Visceral Fat: Fat stored around organs (visceral fat) poses a greater risk to cardiovascular health than subcutaneous fat (fat under the skin). It’s essential to monitor and manage visceral fat through regular testing, such as a DEXA scan, to reduce the risk of metabolic dysfunction.

Lifestyle Factors Affecting Cardiovascular Health

Smoking and High Blood Pressure: Both smoking and high blood pressure damage the endothelium, the inner lining of blood vessels, leading to an increased risk of cardiovascular events. Quitting smoking and managing blood pressure are crucial steps for heart health.
Start Early: Cardiovascular prevention should begin in your 30s, with regular testing, healthy lifestyle choices, and medication if necessary to reduce risk factors early on.

Cancer Prevention and Early Detection

Colonoscopy: It's recommended to start screening for colon cancer at age 40, which is earlier than the typical recommendation of 45 or 50.
Breast Cancer: Annual breast cancer screenings should begin early to detect any issues as soon as possible.
Immunotherapy: This is an advanced treatment option for cancer that uses the body’s immune system to fight the disease.
Early Screening: The most effective way to combat cancer is through early screenings, which increase the chances of successful treatment and survival.

Alzheimer’s Disease – Prevention, Risks, and Strategies

The longer we can go without developing dementia, the better our odds of living longer, and living in better health. Alzheimer’s Disease is not well understood at all. But until science comes up with more effective treatments, prevention is our only option.

1. Genetic Risk Factors

Alzheimer’s risk is influenced by genetic factors, particularly the APOE gene.

APOE Genotype Test: A key test to determine your genetic risk of Alzheimer’s.

Having APOE E4 Variant: Increases the risk of developing Alzheimer’s by 2 to 12 times.

If you have one copy (E4/E3): Greater risk than average.
If you have two copies (E4/E4): The risk of developing Alzheimer’s increases 12 times.

Having APOE E2 Variant: This variant appears to offer some protection against Alzheimer’s.

E2/E2: 20% lower chance of developing the disease.
E2/E3: 10% lower risk.

While genetics play a role, lifestyle factors are crucial in mitigating risk, even for those with a genetic predisposition.

2. Risk Factors for Alzheimer’s

There are several other factors that significantly increase the risk of developing Alzheimer’s, including:

Vascular Health: Conditions that affect blood vessels, such as high blood pressure and cardiovascular diseases, increase the risk of Alzheimer’s.
Type 2 Diabetes: Having diabetes doubles or even triples the risk of Alzheimer’s. (It important to check DEXA because visceral fat)
Menopause and Hormonal Changes: Alzheimer’s is twice as common in women, and hormonal changes around menopause may contribute.
Lifestyle Factors:

Smoking: A well-established risk factor.
Head Injuries: Traumatic brain injuries or strokes are linked to increased Alzheimer’s risk.
Depression: Depression may also elevate the risk of cognitive decline.

Alzheimer is twice as common in women than men. And affect more Caucasian people.
Number of children
Age of first menstruation
Exposure to oral contraceptives

Note : When reading some of these risk factors it seemed that some of them were not widely accepted or proven. Some of these associations might be suspected or theorised, but not conclusively demonstrated by research. Some of them we mentioned very quickly in the book with not many details.

3. Preventive Measures for Alzheimer’s

While genetics and some risk factors are beyond control, many lifestyle choices can significantly reduce the risk of Alzheimer’s or delay its onset. Focus on your metabolic health especially if you are at high risk for Alzheimer. Nutrition, physical activity, cognitive training

TIME IS KEY. We need to think about prevention early, and the more the deck is stacked against you genetically, the harder you need to work and the sooner you need to start. We need to play a very long game.

3.1 What’s good for the heart is good for the brain

That is, vascular health (meaning low apoB, low inflammation, and low oxidative stress) is crucial to brain health.

3.2. Diet and Nutrition

Mediterranean Diet: Studies show that a diet rich in mono-unsaturated fats, such as olive oil, and low in carbohydrates, can reduce Alzheimer’s risk.

Key Components:

More mono-unsaturated fats (from olive oil, avocados, nuts).
Regular consumption of fatty fish (omega-3s like DHA).
Less sugar and processed carbohydrates.

Ketogenic Diet: Studies suggest that a ketogenic diet, which forces the body to burn fat for fuel,

may improve cognition and memory in people with mild cognitive impairment and early-stage Alzheimer’s.

3.3. Exercise

Our Most Powerful Tool for Preventing Cognitive Decline is Exercise: We’ve talked about diet and metabolism, but exercise is just as important. It’s a foundation of his Alzheimer’s prevention program.

Cardio Exercises: Endurance exercises like walking, cycling, and swimming have been shown to target brain regions responsible for cognition and memory (e.g., the hippocampus).
Strength Training: Studies show that people with low grip strength (good to evaluate overall strength) have a 72% higher incidence of dementia.
VO2 Max Training: Improving aerobic capacity can also help maintain cognitive function.

Regular exercise not only strengthens the body but also lowers stress, improves metabolic health, and supports brain health, all of which reduce Alzheimer’s risk.

3.4. Sleep

Sleep plays a critical role in memory consolidation and overall brain health. Poor sleep is associated with a higher risk of Dementia.

Cf Chapter related to Sleep.

3.5.. Emerging Strategies and Studies

Research into Alzheimer’s prevention is ongoing, and several promising strategies are emerging:

Sauna Use: dry sauna 4 times a week for 20 minutes
Oral health (page 203) + flossing
High vitamin b level - lowering homocysteine with vitamin b
Hormones replacement therapy for women during pre menopause to menopause
Supplements with omega 3 fatty acid DHA found in fish oil may help maintain brain health

Exercice

More muscle mass is associated with a longer life.
Regular exercise leads to significant health benefits (not surprising) but it’s beyond what is commonly known. Absolutely the best leverage for health on longevity, with amazing results
Both cardio and strength training are crucial for optimising health and longevity.

Cardio and Aerobic Efficiency

Cardio's Role in Brain Health:

Cardiovascular exercises improve the health and function of the hippocampus, which is essential for memory.
Exercise can be a valuable tool in preventing Alzheimer's and other forms of cognitive decline.

Zone 2 Training

What is Zone 2

Zone 2 is typically 70-85% of your maximum heart rate.
You should be able to talk, but not feel like having a long conversation.
Lactate levels should be between 1.7 to 2 millimoles.

Benefits:

Builds a base for endurance and improves mitochondrial efficiency, helping you burn fat more efficiently.
Lower intensity exercise burns fat when high intensity rely on glucose.
The more efficient is your mitochondria the greater your ability to burn fat
Ability to use both fat & glucose is called metabolic flexibility & it's what we want.
Zone 2 build a base for endurance and make your mitochondria better

Metabolic Flexibility: The ability to use both fat and glucose for energy, which is the ideal state for health.

Check this text for tracking you zone 2 progression

Vo2max

What is VO2 Max: The maximum rate of oxygen consumption, a key indicator of cardiovascular fitness.

Importance: Increasing VO2 max from the bottom quartile to just below average is linked to a 50% reduction in all-cause mortality.

How to Improve VO2 Max:

After 5-6 months of consistent Zone 2 training, introduce VO2 max training.
Sequence: High-intensity intervals of 3-8 minutes once or twice a week.
Example: Run or bike at max pace for 4 minutes, followed by 4 minutes at low intensity (heart rate below 100). Repeat 4-6 times, then cool down.

Frequency: Test your VO2 max once a year.

Strength Training

More muscle mass is associated with a longer life.

Lifting Heavy Weights:

Lift heavy weights four times a week to build and maintain muscle mass.
Muscle strength is crucial for long-term health, particularly as you age. Especially for women (even more for women it is super important to highlight because women tend to do more cardio and by shy with lifting -> Women really need to lift
Grip Strength (which is a great indicator of overall strength) is a key indicator of overall strength and longevity. Strong grip strength is linked to better outcomes in aging.
Pulling Strength : Focus on exercises that improve pulling strength, such as using a rowing machine, to build functional strength.

Strength and Bone Health:

Hormone Replacement Therapy (HRT): Attia supports HRT for women in menopause to help maintain bone density and muscle mass. (here Dr.Stacy Smith seems to say it’s possible to train for it without necessarily doing HRT, but it a debatable subject)
Bone Dimensions: Maintaining both bone dimensions and muscle mass is important for overall health and preventing fractures.
Eccentric Strength: This is the control you exert when lowering weights or moving downhill—important for preventing falls and orthopedic injuries.

What to do when someone as a decrease in bone mase dimension :

Stability

The most important rule : Don't hurt yourself -> if you do you won’t be able to train anymore

Stability and Injury Prevention:

Prioritize stability over simply trying to lift heavier weights or push yourself to the maximum every day.
Avoid the mindset of chasing the "best workout" every time by maxing out your weights or capacity—this increases the risk of injury.
Focus on doing the right movements and maintaining proper form for long-term benefits.

Stability and Longevity:

As you age, stability becomes even more important for maintaining mobility and preventing falls.
The ability to balance on one leg, especially in individuals over 50, is correlated with increased longevity and future health outcomes.

Practices for Stability

Dynamic Neuromuscular Stabilization (DNS): A method of training that focuses on restoring and maintaining proper joint and movement stability through targeted neuromuscular exercises. DNS helps improve body mechanics, balance, and overall movement efficiency, which lowers the risk of injury during workouts and daily life.

Breathing Exercises: Proper breathing techniques play a crucial role in stabilizing the core and maintaining good posture during physical activity. Providing a strong foundation for movement.

Toe Yoga : Your toes are the foundation of your stability—strengthening and mobilizing them improves balance and posture.

Simple exercises like lifting and spreading your toes, or practicing movements that engage and strengthen your foot muscles, contribute to overall stability.

Nutrition

Eliminate Sugar and Processed Foods and Alcohol

- Stop all sugar sweetened beverage (stick to water)

- Quite sweet fruit juices

- Quite food with added sugar (ice cream, bonbon, cake cookies pies, chocolate, ketchup, sport drinks, flavoured coffee, protein bar)

- carbohydrate restrictions

- Quit Alcohol

Monitor Your Blood Sugar

Use a Continuous Glucose Monitor (CGM) for a few weeks to see how different foods affect your blood sugar.
This helps identify which foods cause blood sugar spikes so you can adjust your diet.
Once you understand you can quit using it.

Prioritise Protein (women too - Especially Women in the late 40s!)

Protein is crucial—the US government’s 0.8g/kg recommendation is too low.
Daily Protein Intake:

Minimum: 1.6g/kg of body weight.
Active people: 2.2g/kg.

Spread your intake across meals to avoid losing amino acids to oxidation.

Sleep

1. Sleep Aids and Environment

If you need drug : Trazodone good to sleep : 50 to 100 milligram because we want to avoid drowsiness the next day
Lighting: Gradually dim lights at night and use warm lighting (avoid blue light).
Screen Time: Avoid laptops, phones, and video games at least 1 hour before bed; don’t bring them into the bedroom.
Room Temperature: 18°C (64°F) is optimal for sleep.
Pre-Bed Routine: Take a warm shower, then go to a cool room to drop body temperature.
Cooling Mattress: Use one for a more comfortable sleep.
No Alcohol: Avoid drinking before bed.

2. Daytime Habits for Better Sleep

Get Sunlight: Exposure to daylight helps regulate your sleep cycle.
Manage Stress: Avoid stress-inducing activities (like checking work emails) before bed to prevent activation of the sympathetic nervous system.
Relaxation: Use meditation or relaxation techniques to calm the nervous system before bed.
Regular exercise.
Getting outdoors.
Healthy eating and avoiding late-night snacks.
No alcohol.
Low stress and setting work boundaries.

3. Tips for Insomnia

Stop fighting insomnia: Change rooms and do something with no purpose, like drawing, painting, meditation, or reading a boring book.
Late Chronotype: You might naturally fall asleep later, so adjust your expectations.
Cognitive Behavioral Therapy (CBT): Consider CBT for insomnia.

Emotional Health

Least interesting part of the book, story telling focus on his experience.

Ask yourself: Why poison the environment you have to live in?

Look Into : Dialectical Behavior Therapy (DBT) - DBT is a valuable tool for emotional regulation, teaching skills like mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness.

Foxo3

FOXO3 is a gene linked to longer life and helps prevent cells from becoming cancerous.

You can activate this gene through simple behaviors like eating less and regular exercise, both of which support better cell health and longevity.

Rapamycin

Rapamycin is the only drug that has consistently been shown to significantly extend the lifespan of mice, with multiple labs replicating these results. Unlike other compounds, such as resveratrol or nicotinamide riboside, which haven't shown consistent results across different studies, rapamycin stands out. Interestingly, the effects of rapamycin can also be mimicked by eating less, making caloric restriction a non-pharmaceutical way to potentially achieve similar benefits.

Eating Less & Autophagy

Reducing food intake, as seen in lab animals, has been shown to extend lifespan. Fasting or eating less triggers a process called autophagy, where the body clears out damaged cells and regenerates healthier ones. Autophagy can also be activated by drugs like rapamycin, but fasting offers a natural way to support cell repair and longevity.

Note for Women : Fasting studies are done mostly on men, fasting can have more negative impact for women. Especially if you exercise while fasting. -> Women should end the fast before exercising. Source Here

Body Fat vs. Visceral Fat

Not all fat is the same.

Body fat (subcutaneous fat under the skin) is not necessarily harmful

But visceral fat, which surrounds organs like the liver and heart, is a serious problem. When your body can't store more fat under the skin, it begins to accumulate around vital organs, increasing health risks.

You can look overweight but have little visceral fat and be metabolically healthy.
Conversely, someone who appears thin may still have a high amount of visceral fat and be at greater risk.

Visceral fat is strongly linked to conditions like diabetes, which is highly correlated with cancer, cholesterol problems, and Alzheimer’s.

To monitor visceral fat and overall metabolic health, an annual DEXA scan is recommended.

Focus on metabolic health, because it is the cause of many diseases

Fructose and Uric Acid

Avoid Added Fructose: Fructose is a form of sugar that is easily stored as fat in the body, especially when consumed in processed foods like salad dressings, yogurt cups, and soft drinks. It’s important to minimize these sources of fructose.
Fruit vs. Juice: Fructose from whole fruits is okay because it's digested slowly due to fiber, but fruit juices like apple juice should be avoided since they deliver too much fructose too quickly. An apple is good, but apple juice is not.
Uric Acid: High levels of uric acid can lead to increased fat storage and high blood pressure. Fructose contributes to raising uric acid, but other factors can also influence it. It's important to test your uric acid levels regularly.
Be Cautious with Smoothies: Smoothies, like fruit juices, can deliver fructose too quickly and should be consumed with care.
