From Keto to Carnivore: Decoding Low Carb Diets for Ultimate Health and Vitality
By Stephen Fitzmeyer, MD
Introduction:
In the quest for improved health and weight management, numerous dietary approaches have gained popularity. Among the most well-known are the low carb diets, including the ketogenic diet (keto) and the carnivore diet. However, it is important to understand the subtle nuances and benefits of each variation, as well as other popular low carb diets such as the Paleo, Mediterranean, and Standard American Diet (S.A.D.). In this article, we will explore the differences and benefits of these dietary choices, shedding light on the variables that make each one unique.
The Ketogenic Diet (Keto):
The ketogenic diet is a low carb, high fat diet that encourages the body to enter a state of ketosis. By significantly reducing carbohydrate intake and increasing fat consumption, the body shifts from using glucose as its primary fuel source to using ketones. This metabolic state has been associated with several benefits, including weight loss, improved insulin sensitivity, and increased mental clarity. Additionally, keto has shown promise in managing epilepsy and certain neurological disorders.
The Carnivore Diet:
At the other end of the spectrum lies the carnivore diet, which emphasizes exclusively animal products and eliminates plant-based foods entirely. This ultra-low carb, high fat, and high protein approach aims to mimic the dietary patterns of our ancestors. Advocates claim that eliminating plant foods can reduce inflammation, promote weight loss, and improve digestion. However, it is important to note that the carnivore diet is highly restrictive and lacks the diversity of nutrients found in a balanced diet.
The Paleo Diet:
The Paleo diet seeks to emulate the eating habits of our Paleolithic ancestors. It promotes the consumption of whole, unprocessed foods such as lean meats, fish, fruits, vegetables, nuts, and seeds, while excluding grains, legumes, dairy products, and processed foods. By focusing on nutrient-dense foods and eliminating potential allergens, the Paleo diet aims to support weight loss, improve digestion, and reduce the risk of chronic diseases.
The Mediterranean Diet:
The Mediterranean diet is inspired by the traditional eating patterns of countries bordering the Mediterranean Sea. It emphasizes plant-based foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds, while incorporating moderate amounts of fish, poultry, and dairy products. This approach is rich in healthy fats, antioxidants, and fiber, which have been associated with a reduced risk of heart disease, improved brain function, and overall longevity.
The Standard American Diet (S.A.D.):
The Standard American Diet, unfortunately, is characterized by a high intake of processed foods, refined sugars, unhealthy fats, and a low consumption of fruits, vegetables, and whole grains. This diet is associated with a variety of health problems, including obesity, diabetes, heart disease, and certain types of cancer. It lacks the nutrient density and balance necessary for optimal health.
Benefits of Each Approach:
Keto: Weight loss, improved insulin sensitivity, increased mental clarity, potential therapeutic benefits for epilepsy and neurological disorders.
Carnivore: Potential for reduced inflammation, weight loss, and improved digestion. However, it may lack essential nutrients and long-term sustainability.
Paleo: Improved weight management, reduced risk of chronic diseases, increased nutrient intake, elimination of potential allergens.
Mediterranean: Heart health, improved brain function, longevity, reduced risk of chronic diseases, balanced nutrient intake.
S.A.D.: No significant benefits compared to the other diets mentioned. Associated with various health issues.
Conclusion:
Choosing the right low carb diet depends on individual goals, preferences, and health considerations. While the ketogenic and carnivore diets offer unique metabolic effects, it is important to consider the
long-term sustainability and potential nutrient deficiencies. The Paleo and Mediterranean diets provide a balanced approach by emphasizing whole, unprocessed foods and diverse nutrient profiles. In contrast, the Standard American Diet (S.A.D.) is associated with numerous health problems due to its reliance on processed and unhealthy foods.
It is essential to note that individual responses to different diets may vary. What works for one person may not yield the same results for another. It is always advisable to consult with a healthcare professional or a registered dietitian before making significant dietary changes.
Ultimately, the key to a successful and sustainable low carb diet lies in finding a balance that aligns with your health goals and preferences. Incorporating whole, nutrient-dense foods while reducing processed carbohydrates can have a positive impact on weight management, overall health, and disease prevention. By understanding the variables and benefits of different low carb diets, you can make an informed decision and embark on a journey towards improved well-being.
Comparison chart highlighting the macronutrient composition of each diet:
Please note that the macronutrient ratios mentioned above can vary based on individual preferences and specific interpretations of each diet. Additionally, the “Moderate” category indicates a more balanced distribution rather than being excessively high or low.
It’s important to keep in mind that macronutrient ratios can be adjusted within each diet based on individual needs, health goals, and preferences. Consulting with a healthcare professional or a registered dietitian can provide personalized guidance for determining the ideal macronutrient breakdown for your specific circumstances.
Remember that while macronutrients play a significant role in dietary choices, the quality of food, micronutrient content, and overall balance of the diet are also crucial factors to consider for long-term health and well-being.

The Rise of Overweight/Obesity in the U.S.: Examining the Influence of Dietary Guidelines, the Food Pyramid, and Ancel Keys
By Stephen Fitzmeyer, MD
Introduction: The United States has experienced a significant increase in overweight and obesity rates over the past few decades, leading to serious health concerns. It is intriguing to examine the correlation between the rise in overweight/obesity and the transformation of the American diet, particularly with the introduction of dietary guidelines and the prominent role played by Ansel Keys. In this article, we delve into the historical context and explore how the shift away from fresh whole foods, influenced by Keys’ research, may have inadvertently contributed to the obesity epidemic in the United States.
The Era of Fresh Whole Foods: Before the introduction of dietary guidelines in the 1980s, the American diet primarily consisted of fresh, whole foods. Meals were often prepared from scratch, using ingredients sourced directly from farms and local markets. Fresh fruits and vegetables, meats, and unprocessed grains were the foundation of everyday eating, providing a nutrient-dense and balanced approach to nutrition.
Ansel Keys and Dietary Fat: Ansel Keys, a prominent scientist, conducted influential research in the mid-20th century that examined the relationship between dietary fat and heart disease. His work, known as the “Seven Countries Study,” suggested a correlation between high-fat diets and increased risk of cardiovascular issues. However, Keys’ study focused on selected countries, disregarding nations with contrasting dietary patterns that contradicted his findings.
The Impact of Keys’ Findings: Keys’ research gained significant attention and led to a shift in nutritional thinking. Dietary fat, particularly saturated fat, became vilified, and the notion that a low-fat diet was crucial for maintaining heart health took root. As a result, dietary guidelines and recommendations began emphasizing the reduction of fat intake, leading to the promotion of low-fat and fat-free products in the market.
The Emergence of Processed Foods: The low-fat movement led to a surge in processed food products marketed as healthy alternatives. With the focus on reducing fat, manufacturers started formulating products with reduced fat content but compensated by adding excessive amounts of sugar, artificial additives, and refined carbohydrates. This shift in the food industry coincided with the introduction of dietary guidelines, further driving the consumption of processed foods among Americans.
Unintended Consequences: The shift away from fresh whole foods towards processed, low-fat alternatives had unintended consequences. These processed foods were often calorie-dense, nutrient-poor, and contributed to overconsumption. The replacement of dietary fats with refined carbohydrates and added sugars not only affected overall calorie intake but also disrupted metabolic processes, leading to weight gain and related health issues.
Reevaluating Dietary Choices: In recent years, there has been a growing realization that the previous low-fat paradigm may have played a role in the obesity epidemic. Many experts advocate for a return to a more balanced approach, focusing on the consumption of whole, unprocessed foods and reevaluating the role of dietary fats. This includes embracing healthy fats such as those found in avocados, nuts, olive oil, fatty meats, eggs, butter, and cheeses.
Empowering Individuals through Education: To combat the rise of overweight/obesity, it is essential to empower individuals with knowledge and encourage them to make informed dietary choices. By educating ourselves about the benefits of fresh whole foods, understanding the potential pitfalls of processed foods, and reevaluating the role of dietary fats, we can make strides towards improving our overall health and well-being.
Conclusion: The rise of overweight and obesity in the United States coincides with the transformation of the American diet, influenced by the introduction of dietary guidelines and the impact of Ansel Keys’ research. While Keys’ findings had noble intentions, the emphasis on low-fat diets and the
proliferation of processed, low-fat alternatives may have inadvertently contributed to the obesity epidemic. It is important to acknowledge the historical context and the role played by fresh whole foods in the American diet before the era of dietary guidelines. By revisiting and embracing a diet centered around whole, unprocessed foods, we can reclaim a healthier approach to nutrition.
Moving forward, it is crucial to continue educating individuals about the importance of a balanced diet that includes nutrient-dense foods and minimizes reliance on processed and refined options. By fostering a culture of mindful eating and promoting the consumption of fresh, whole foods, we can work towards reversing the alarming trends of overweight and obesity and promoting a healthier future for all.
Coding Evidence-Based Medicine into Web-Based Applications
By Stephen Fitzmeyer, MD
Evidence-based medicine (EBM) is a medical approach that involves using the best available evidence to make informed clinical decisions. The goal of EBM is to improve the quality of patient care by integrating research evidence, clinical expertise, and patient preferences into clinical decision making. In recent years, there has been a growing interest in using technology to support EBM and help clinicians make evidence-based decisions. Web-based applications are a popular way to accomplish this goal.
Web-based applications that incorporate EBM can provide clinicians with easy access to the latest research evidence, as well as clinical practice guidelines and other relevant resources. These applications can help clinicians make informed decisions about diagnosis, treatment, and management of a wide range of medical conditions.
The process of building a web-based EBM application involves several steps. The first step is to identify the target audience and determine the specific clinical needs that the application will address. This may involve conducting a needs assessment and identifying gaps in current clinical practice.
The second step is to identify relevant EBM resources and integrate them into the application. This may involve using electronic databases, such as PubMed or Cochrane Library, to search for the latest research evidence. It may also involve incorporating clinical practice guidelines, systematic reviews, and other evidence-based resources into the application.
Once the relevant EBM resources have been identified, the next step is to design the application’s user interface. The application should be easy to navigate, intuitive to use, and provide users with relevant information at the appropriate time. The design of the application should be based on user-centered design principles, which involve actively involving users in the design process and incorporating their feedback into the final product.
After the application has been designed, the next step is to develop the application using web development languages and frameworks such as HTML, CSS, JavaScript, and React. The application may also incorporate server-side programming languages such as PHP or Python, and databases such as MongoDB or MySQL to store and retrieve data.
Finally, the application should be tested and validated to ensure that it is functioning as intended and providing accurate and reliable information to users. This may involve user testing, where the application is tested by actual users, as well as usability testing, where the application is tested for ease of use and effectiveness.
In conclusion, web-based applications that incorporate EBM can provide clinicians with easy access to the latest research evidence and clinical practice guidelines, helping them make informed decisions about patient care. The development of these applications involves identifying the target audience and their clinical needs, integrating relevant EBM resources, designing an intuitive user interface, developing the application using web development languages and frameworks, and testing and validating the application to ensure that it is effective and reliable. By following these steps, developers can build web-based EBM applications that improve patient care and support evidence-based decision making in clinical practice.

From Cholera to COVID-19: The Role of Epidemiology in Disease Outbreaks
By Stephen Fitzmeyer, MD
The cholera outbreak in 1854 in London, and the work of John Snow, is considered a turning point in the field of epidemiology. The outbreak caused thousands of deaths and was traced back to contaminated water from the Broad Street pump. Snow’s investigation led him to identify the source of the outbreak, and he subsequently recommended measures to prevent the spread of cholera.
Fast forward to modern times, and we are facing a new epidemic – COVID-19. The similarities between the two outbreaks are striking, and so are the differences. Like cholera, COVID-19 is a highly contagious disease that spreads through contact with infected individuals or surfaces. However, unlike cholera, COVID-19 is caused by a novel virus that is still not fully understood.
Epidemiology played a crucial role in both outbreaks. In the case of cholera, Snow used epidemiological methods to map the spread of the disease and identify the source of the outbreak. He collected data on the location of cases and the source of water for the affected individuals, and used this data to create a map that showed a clear association between the cases and the Broad Street pump. This data-driven approach was a key factor in his successful intervention.
Similarly, epidemiology has played a critical role in the management of COVID-19. Epidemiologists have been tracking the spread of the disease, identifying risk factors and patterns of transmission, and providing guidance on how to mitigate the spread of the virus. Epidemiological models have been used to predict the course of the pandemic, and to inform public health policies and interventions.
However, there are also significant differences between the two outbreaks. COVID-19 is a much more complex disease than cholera, with a wide range of symptoms and outcomes. The virus is highly contagious and can be spread by asymptomatic carriers, making it much more challenging to control. The development of effective vaccines and treatments has been a major focus of the public health response to COVID-19, and epidemiology has played a critical role in evaluating the effectiveness of these interventions.
In conclusion, the cholera outbreak and the work of John Snow laid the foundation for modern epidemiology, and the lessons learned from that outbreak have helped us manage and control many subsequent disease outbreaks. The COVID-19 pandemic has presented a new set of challenges, but the principles of epidemiology remain essential to understanding and controlling the spread of the virus. By continuing to apply these principles, we can hope to mitigate the impact of the pandemic and prepare for future outbreaks.

Unveiling the Mathematics of Epidemiology: Analyzing Disease Patterns and Prevention Strategies
Epidemiology, the scientific study of health and disease distribution in populations, is a field that relies on mathematical concepts and analysis to understand and combat public health challenges. In this article, we will explore some key mathematical examples that highlight the significance of epidemiology in healthcare.
Incidence and Prevalence: Let’s consider a hypothetical population of 10,000 individuals. Over the course of one year, 500 new cases of a particular disease are diagnosed. The incidence of the disease in this population would be calculated as follows:
Incidence = (Number of new cases / Total population) x 1,000 Incidence = (500 / 10,000) x 1,000 Incidence = 50 cases per 1,000 population
Prevalence, on the other hand, measures the proportion of individuals with the disease at a specific point in time. If, at the beginning of the year, there were already 200 existing cases in the population, the prevalence of the disease would be:
Prevalence = (Number of existing cases / Total population) x 1,000 Prevalence = (200 / 10,000) x 1,000 Prevalence = 20 cases per 1,000 population
These calculations provide healthcare providers with valuable information about the disease burden and help in identifying trends and potential risk factors.
Risk Factors: Let’s consider a study examining the relationship between smoking and the development of lung cancer. Researchers gather data from a sample of 1,000 individuals, finding that 300 of them are smokers and 100 of those smokers develop lung cancer over a five-year period. The incidence rate of lung cancer among smokers can be calculated as:
Incidence Rate = (Number of new cases among smokers / Total number of smokers) x 1,000 Incidence Rate = (100 / 300) x 1,000 Incidence Rate = 333.33 cases per 1,000 smokers
This example demonstrates how epidemiology can quantify the association between a specific risk factor (smoking) and the occurrence of a disease (lung cancer).
Outbreak Investigation: During an outbreak investigation, data collection and analysis are crucial for identifying the source and mode of transmission of a disease. Let’s say there is an outbreak of a foodborne illness, and investigators collect information from 500 affected individuals. By analyzing the data, they find that 400 of them consumed a particular brand of contaminated food. This finding suggests a potential association between the contaminated food and the outbreak.
Screening: To illustrate the importance of screening, let’s consider a population of 2,000 individuals eligible for a breast cancer screening program. The screening test has a sensitivity of 90% and a specificity of 95%. Out of the 50 individuals who have breast cancer, 45 will test positive (true positives) while 5 will test negative (false negatives). Out of the 1,950 individuals without breast cancer, 1,852 will test negative (true negatives) while 98 will test positive (false positives). These numbers highlight the trade-off between identifying true cases of breast cancer and the potential for false-positive results.
Clinical Trials: Clinical trials rely on statistical analysis to assess the effectiveness of new treatments or interventions. For instance, a study involving 500 participants might randomly assign half of them to receive a new medication while the other half receives a placebo. By comparing the outcomes between the two groups, researchers can determine the efficacy of the medication and make evidence-based decisions regarding its use in clinical practice.
By understanding these mathematical examples within the context of epidemiology, healthcare providers can gain valuable insights into the distribution and determinants of diseases. This knowledge enables them to develop effective prevention and control strategies, improve population health outcomes,
and make informed decisions in healthcare. The application of mathematics in epidemiology provides a quantitative framework for understanding the patterns and dynamics of diseases within populations.
Mathematics allows us to quantify the incidence and prevalence of diseases, providing a measure of the disease burden and helping healthcare providers allocate resources effectively. By calculating incidence rates, we can assess the risk factors associated with diseases, such as the relationship between smoking and lung cancer.
During outbreaks, mathematical analysis helps investigators identify the source and mode of transmission of diseases, guiding public health interventions to prevent further spread. Screening programs utilize mathematical concepts to evaluate the performance of tests, balancing the need for early detection with the risk of false positives.
Clinical trials, powered by statistical analysis, provide evidence-based information on the efficacy and safety of new treatments. Mathematics helps determine sample sizes, assess treatment outcomes, and draw valid conclusions about the effectiveness of interventions.
The integration of mathematics in epidemiology strengthens the foundation of public health decision-making. It allows healthcare providers to make data-driven assessments, identify high-risk populations, implement targeted interventions, and monitor the impact of preventive measures.
As we continue to navigate the challenges of disease prevention and control, understanding the role of mathematics in epidemiology is paramount. By harnessing the power of numbers, healthcare providers can effectively analyze and interpret health data, paving the way for evidence-based strategies that protect and promote the well-being of populations.

The Importance of Sleep Health: Optimizing Your Rest for Overall Well-being
Getting quality sleep is essential for our overall health and well-being. It not only affects our physical health but also has a significant impact on our mental and emotional well-being. In this article, we’ll explore the importance of sleep health and discuss various factors that can influence the quality of our sleep.
Adaptive and Maladaptive Cortisol: The Impact of Stress Hormones Cortisol, commonly known as the stress hormone, plays a crucial role in our sleep-wake cycle. In healthy individuals, cortisol levels naturally rise in the morning to help us wake up and stay alert throughout the day. However, problems arise when cortisol levels become dysregulated, leading to maladaptive responses that can disrupt our sleep patterns. Excessive exposure to stress, screen time, and constant alerts can exacerbate cortisol levels, making it challenging to unwind and fall asleep at night.
Blue Light and Silence: Creating a Sleep-Conducive Environment In today’s digital age, we are constantly exposed to screens emitting blue light, which can interfere with our natural sleep rhythms. To counteract this, it’s beneficial to establish a blue light curfew by avoiding screens for at least an hour before bed. Additionally, creating a quiet and peaceful environment can help signal to your body that it’s time to rest. Consider incorporating relaxation techniques such as meditation or gentle stretching before bedtime to promote a calm state of mind.
Sleep Problems and Night Shifts: Finding Balance Night shift work can disrupt our body’s natural circadian rhythm, making it difficult to achieve restful sleep during the day. If you find yourself working night shifts, it’s crucial to prioritize your sleep by creating a dark and quiet sleeping environment. Invest in blackout curtains or a sleep mask to block out sunlight, and use earplugs or white noise machines to minimize distractions. Establishing a consistent sleep schedule, even on your days off, can also help regulate your body’s internal clock.
Mental Health and Sleep: A Bidirectional Relationship The relationship between mental health and sleep is bidirectional – poor sleep can contribute to mental health issues, and mental health issues can disrupt sleep patterns. If you’re experiencing difficulties sleeping due to stress, anxiety, or depression, it’s essential to address these underlying concerns. Seek support from healthcare professionals who can help you develop coping strategies, such as cognitive-behavioral therapy for insomnia (CBT-I), which can improve both sleep and mental well-being.
Exercise Patterns: Promoting Restful Sleep Regular exercise can significantly impact the quality of our sleep. Engaging in physical activity, especially earlier in the day, can help regulate our body’s internal clock and promote restful sleep at night. However, intense exercise close to bedtime may have stimulating effects, making it harder to fall asleep. Find a balance that works for you and consider incorporating activities such as yoga, stretching, or low-impact exercises in the evening to unwind and prepare your body for a good night’s sleep.
In conclusion, prioritizing sleep health is crucial for our overall well-being. By understanding the impact of cortisol, implementing strategies to reduce screen time and exposure to blue light, and creating a sleep-conducive environment, we can improve our sleep quality. Additionally, recognizing the challenges of night shifts, addressing mental health concerns, and incorporating exercise patterns that support restful sleep can all contribute to a healthy sleep routine.
Remember, sleep is a vital component of a healthy lifestyle, and if you consistently struggle with sleep problems, it’s important to consult with a healthcare professional who can provide personalized guidance and support.
