Keto vs GLP-1

Rethinking Cardiovascular Health: Beyond LDL as a Marker for Disease

Fellow physicians,

For decades, we’ve relied on LDL as the primary marker for assessing cardiovascular disease (CVD) risk. However, recent research and patient outcomes are prompting us to reconsider this approach. Cardiovascular health is multifaceted, and addressing root causes rather than singular markers like LDL can guide us to better patient outcomes, particularly in our current environment of rising metabolic and liver disease.

1. GLP-1 Medications: A Bridge, Not a Solution

While medications like Rybelsus (a GLP-1 receptor agonist) offer short-term weight-loss benefits, they come with limitations. Long-term use is costly and can bring side effects such as nausea, diarrhea, and gallbladder issues. Our patients may be drawn to the “quick fix,” but as we know, sustainable health often demands a lifestyle overhaul.

GLP-1s should be viewed as a temporary tool—a way to kick-start weight loss and motivate patients while emphasizing that lifestyle adjustments provide a sustainable path. Ideally, these medications serve as a bridge to instill healthier habits rather than a permanent solution.

2. The Real Culprit: Insulin Resistance and NAFLD

While elevated LDL is traditionally seen as a red flag for CVD, the underlying issue for many patients is actually insulin resistance. Insulin resistance is at the heart of metabolic syndrome, which drives non-alcoholic fatty liver disease (NAFLD)—a condition increasingly common, even among adolescents.

By focusing on insulin resistance rather than LDL alone, we tackle the metabolic issues that lead to NAFLD. Evidence shows that low-carb diets like keto can reverse fatty liver by lowering triglycerides and reducing liver fat, often leading to improved liver enzyme levels and overall liver health.

3. Better Metrics for Cardiovascular Health: TG/HDL Ratio and LDL Particle Size

Assessing cardiovascular risk requires a broader perspective. Rather than fixating on LDL, consider the triglyceride-to-HDL (TG/HDL) ratio—a stronger indicator of metabolic health. A lower TG/HDL ratio typically correlates with better heart health. Studies have shown that keto and low-carb diets improve this ratio by raising HDL and lowering triglycerides.

Additionally, while LDL levels may not change dramatically on a low-carb diet, LDL particles often shift to a larger, safer size, further reducing cardiovascular risk. These changes are more predictive of positive outcomes than LDL levels alone.

Moving Forward: An Integrated Approach to Patient Health

Incorporating GLP-1s can help patients get started, but it’s lifestyle modifications that will sustain them. Addressing insulin resistance with targeted lifestyle changes like low-carb eating can help reverse NAFLD, improve metabolic health, and reduce the risk of CVD.

Our role is to guide patients not only toward initial success but also to long-term, sustainable health. By shifting the focus from LDL to insulin resistance, we can empower them to achieve better outcomes and transform their health for the future.

Ketones vs. Glucose

Explaining How Glucose and Ketones Become ATP: Why Ketosis and Fat Adaptation Boost Health

Fuel Sources

When it comes to energy, the body has two primary fuel sources: glucose and ketones. While glucose is often the default source, especially on a typical high-carb diet, ketones become the primary fuel under low-carb or fasting conditions. Ketosis, the metabolic state where the body produces ketones from fat, isn’t just about an alternative fuel source; it also offers several health benefits, including weight loss, improved metabolic health, reduced cardiovascular disease risk, and fat adaptation. Let’s dive into how glucose and ketones each produce ATP and why ketosis is a preferred metabolic state for overall health.

ATP: The Body’s Essential Energy Currency

ATP (adenosine triphosphate) fuels virtually every function in our bodies, from muscle contractions to cognitive activities. The body produces ATP by metabolizing nutrients through complex biochemical pathways, using glucose and ketones as primary fuels. Interestingly, ketones produce more ATP per molecule than glucose, making them an efficient energy source, especially beneficial during ketosis.

Pathway 1: Converting Glucose to ATP

Under normal dietary conditions, glucose is the body’s main energy source. Here’s how glucose becomes ATP through a process called cellular respiration:

Step 1: Glycolysis

  1. Breakdown of Glucose: In the cytoplasm, glucose is split into two molecules of pyruvate.
  2. Initial ATP Yield: Glycolysis yields 2 ATP per glucose molecule and produces NADH (an electron carrier for later stages).

Step 2: Pyruvate to Acetyl-CoA

  1. Conversion in the Mitochondria: Pyruvate enters the mitochondria and is converted to acetyl-CoA, releasing CO₂ and generating more NADH.

Step 3: Citric Acid Cycle (Krebs Cycle)

  1. Energy Harvesting: Acetyl-CoA enters the citric acid cycle, where it is broken down to produce NADH and FADH₂, which fuel ATP production in the next step.

Step 4: Electron Transport Chain (ETC)

  1. Main ATP Production: NADH and FADH₂ donate electrons to the ETC, which powers ATP synthase to produce ATP as protons flow back across the mitochondrial membrane.

ATP Yield: Glucose metabolism produces approximately 30-32 ATP per molecule, though it also creates byproducts that can contribute to oxidative stress.

Pathway 2: Converting Ketones to ATP – A More Efficient Pathway

When carbohydrate intake is low, the body shifts to using fat for fuel, producing ketones in the liver. Ketones offer several advantages over glucose, not least of which is their higher energy yield.

Step 1: Ketogenesis in the Liver

  1. Fat Conversion to Ketones: In the liver, fatty acids are converted into ketones (mainly beta-hydroxybutyrate and acetoacetate) through ketogenesis.
  2. Transport to Tissues: These ketones are released into the bloodstream and delivered to cells for energy.

Step 2: Ketone Conversion to Acetyl-CoA

  1. Entry into the Mitochondria: Once inside the cell, ketones are converted back to acetyl-CoA, entering the mitochondria to power the next steps in ATP production.

Step 3: Citric Acid Cycle and Electron Transport Chain

  1. High ATP Yield: Ketones enter the citric acid cycle, generating NADH and FADH₂, which support the electron transport chain.

Why Ketones Produce More ATP: Ketones, specifically beta-hydroxybutyrate and acetoacetate, produce ATP efficiently but with unique metabolic advantages. When fully oxidized, beta-hydroxybutyrate yields approximately 21.5 ATP per molecule, and acetoacetate provides about 19 ATP, giving a combined total of about 40.5 ATP per pair of ketone molecules. In comparison, one molecule of glucose goes through glycolysis, the citric acid cycle, and the electron transport chain to produce around 30-32 ATP in total. Though glucose produces a comparable amount of ATP, ketones offer metabolic stability, lower oxidative stress, and more efficient energy production in low-carb states, making them an effective and sustainable fuel source, especially during fasting or ketogenic conditions.

Why Ketosis and Fat Adaptation Are Beneficial

The body’s ability to switch from glucose to ketones isn’t just a backup mechanism; it provides significant health benefits. This metabolic flexibility is key for weight loss, metabolic health, and cardiovascular protection. Here’s why ketosis, and the fat adaptation that comes with it, is so advantageous:

  1. Weight Loss: Ketosis and fat adaptation (when the body becomes efficient at using fat for fuel) are incredibly effective for weight loss. Since the body can tap into stored fat for energy, people in ketosis burn more fat while maintaining stable energy levels. Ketosis also suppresses hunger hormones, making it easier to stick to a calorie deficit.
  2. Metabolic Syndrome Management: Ketosis helps combat metabolic syndrome by reducing insulin resistance. In ketosis, blood sugar levels are more stable, and the body becomes less reliant on insulin to manage glucose levels. This stability can reverse metabolic syndrome symptoms, which often include high blood pressure, high triglycerides, and abdominal obesity, reducing the risk of type 2 diabetes.
  3. Reduced Cardiovascular Disease Risk: Ketosis supports cardiovascular health by reducing triglyceride levels and increasing HDL (good) cholesterol. Additionally, ketones produce fewer reactive oxygen species (ROS), meaning less oxidative stress and inflammation, both of which contribute to heart disease. The anti-inflammatory effects of ketosis make it beneficial for long-term cardiovascular protection.
  4. Fat Adaptation for Enhanced Energy: Fat adaptation is the process where the body becomes efficient at using fat and ketones as its primary energy source. Once fat-adapted, the body can seamlessly access stored fat for sustained energy, which is especially useful for endurance activities and fasting. People who are fat-adapted experience stable energy without the spikes and crashes associated with glucose, making fat adaptation a valuable state for consistent physical and cognitive performance.
  5. Brain Health and Focus: Ketones readily cross the blood-brain barrier, providing a steady fuel for brain cells. Many people report improved mental clarity, focus, and cognitive endurance in ketosis due to the brain’s ability to efficiently use ketones as fuel, especially when blood sugar levels are low.

Embracing Metabolic Flexibility

By optimizing metabolic pathways to use both glucose and ketones efficiently, the body achieves metabolic flexibility, the ability to switch seamlessly between fuel sources. This flexibility promotes balanced energy levels, reduces cravings, and supports long-term health.

In Summary

  • Glucose Pathway: The body breaks down glucose through glycolysis and the citric acid cycle, yielding around 30-32 ATP. However, glucose metabolism can lead to oxidative stress and relies on stable blood sugar levels for consistent energy.
  • Ketone Pathway: Ketones are produced in the liver from fatty acids and yield more ATP per molecule than glucose. This efficiency, along with reduced byproducts, makes ketones a cleaner and more sustainable fuel, especially during ketosis and fat adaptation.

Ketosis not only provides a high-yield, steady energy source but also supports fat loss, metabolic syndrome improvement, and cardiovascular health. By fostering metabolic flexibility, ketosis allows the body to switch efficiently between glucose and ketones, supporting optimal energy levels and overall health.

This article emphasizes how ketones provide a cleaner, higher-yielding fuel source that supports fat loss, improved metabolic health, and cardiovascular protection. For those looking to optimize their health, embracing ketosis and fat adaptation offers a powerful way to achieve lasting vitality and metabolic balance.

Mitochondrial Metabolism: An Essential Regulator of Adipose Tissue, Metabolic Health, Inflammation, and Brain Function

By Stephen Fitzmeyer, MD

Mitochondria, often referred to as the powerhouses of the cell, play a crucial role in various aspects of human physiology. Beyond their well-known role in energy production, emerging research has shed light on the intricate relationship between mitochondrial metabolism and adipose tissue development and function. Moreover, recent discoveries have highlighted the impact of mitochondrial metabolism on metabolic health, inflammation, and even brain function. Understanding these connections could pave the way for new therapeutic strategies in tackling obesity, metabolic disorders, and neurodegenerative diseases.

Adipose tissue, commonly known as fat, was once perceived as an inert energy storage depot. However, it is now recognized as a dynamic and metabolically active organ that influences whole-body homeostasis. Adipose tissue consists of two main types: white adipose tissue (WAT) and brown adipose tissue (BAT). WAT primarily stores energy in the form of triglycerides, while BAT dissipates energy through thermogenesis. Both types of adipose tissue are influenced by mitochondrial metabolism, albeit in different ways.

In WAT, mitochondrial metabolism has been found to regulate adipogenesis, the process by which precursor cells differentiate into mature adipocytes. Studies have shown that impaired mitochondrial function leads to dysfunctional adipocyte differentiation and altered adipose tissue development. Furthermore, mitochondrial dysfunction in WAT has been linked to insulin resistance, a hallmark of metabolic disorders such as obesity and type 2 diabetes.

On the other hand, BAT is enriched with mitochondria and possesses a high capacity for oxidative metabolism. Brown adipocytes express a protein called uncoupling protein 1 (UCP1), which uncouples oxidative phosphorylation from ATP synthesis, resulting in the generation of heat. This unique characteristic of BAT is essential for maintaining body temperature and regulating energy expenditure. Emerging evidence suggests that impaired mitochondrial metabolism in BAT contributes to obesity and metabolic dysfunction. Conversely, enhancing mitochondrial function in BAT has been proposed as a potential therapeutic strategy to combat obesity and associated metabolic disorders.

Mitochondrial metabolism not only influences adipose tissue development and function but also plays a pivotal role in metabolic health and inflammation. Dysfunctional mitochondria can lead to an imbalance in cellular energy metabolism, resulting in the accumulation of toxic metabolites and the generation of reactive oxygen species (ROS). Excessive ROS production contributes to oxidative stress and chronic low-grade inflammation, which are closely associated with obesity, insulin resistance, and cardiovascular diseases. Inflammation disrupts normal adipose tissue function and can further exacerbate metabolic dysfunction.

Furthermore, recent studies have highlighted the impact of mitochondrial metabolism on brain health and function. The brain is a highly energy-demanding organ, and mitochondrial dysfunction has been implicated in various neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Impaired mitochondrial function in the brain can lead to reduced energy production, compromised neuronal activity, and increased vulnerability to oxidative stress and inflammation. Therefore, maintaining mitochondrial health in the brain is crucial for preserving cognitive function and preventing neurodegeneration.

The intricate interplay between mitochondrial metabolism, adipose tissue development, metabolic health, inflammation, and brain function underscores the importance of understanding these relationships in a holistic manner. Targeting mitochondrial dysfunction may hold promise for therapeutic interventions aimed at improving metabolic health, combating obesity, and even mitigating neurodegenerative diseases.

In conclusion, mitochondrial metabolism is a key regulator of adipose tissue development and function. It influences both white and brown adipose tissues, impacting metabolic health, inflammation, and even brain function. Exploring the molecular mechanisms underlying these connections could provide valuable insights into the pathogenesis of obesity, metabolic disorders, and neurodegenerative diseases. Ultimately, this knowledge may open doors to novel therapeutic strategies that target mitochondrial function, empowering individuals to take control of their metabolic well-being and combat the growing burden of obesity and associated diseases. By promoting mitochondrial health and optimizing adipose tissue function, we may pave the way for a healthier future.

It is evident that mitochondria play a multifaceted role in our bodies, extending far beyond their traditional association with energy production. Their influence on adipose tissue development and function, metabolic health, inflammation, and brain function highlights their significance in maintaining overall physiological balance.

As researchers continue to delve into the intricate mechanisms that govern mitochondrial metabolism, new therapeutic avenues may emerge. Targeted interventions aimed at enhancing mitochondrial function could potentially revolutionize the treatment of metabolic disorders, including obesity, insulin resistance, and neurodegenerative diseases.

Moreover, advancements in our understanding of mitochondrial metabolism may lead to the identification of novel biomarkers for early detection and risk assessment of these conditions. This could enable personalized interventions and interventions at an earlier stage, with the potential to halt or reverse disease progression.

However, it is important to acknowledge that the complexities of mitochondrial metabolism and its interactions with various bodily systems require further investigation. Ongoing research is needed to unravel the underlying mechanisms and to validate the potential therapeutic strategies that target mitochondrial function.

Unlocking the Power of Fat: Understanding Brown Fat, White Fat, and Ketones in Metabolism

By Stephen Fitzmeyer, MD

Introduction:
The human body is a complex machine that relies on various mechanisms to maintain energy balance and regulate metabolism. In recent years, significant research has been conducted to understand the different types of fat and their roles in energy storage, thermogenesis, and overall metabolic health. Additionally, the impact of ketones, particularly beta-hydroxybutyrate (BHB), on uncoupling and thermogenesis in white fat has emerged as a fascinating area of study. This article aims to delve into the fascinating world of brown fat, white fat, and the influence of ketones on fat metabolism.

Brown Fat: The Furnace of Heat Generation
Brown fat, also known as brown adipose tissue (BAT), is a specialized form of fat that plays a crucial role in thermogenesis. Unlike white fat, which primarily stores energy, brown fat is densely populated with mitochondria that contain a unique protein called uncoupling protein 1 (UCP1). UCP1 enables the uncoupling of electron transport and ATP synthesis, diverting energy towards heat production. By activating brown fat, the body can generate heat and maintain body temperature, making it an important component in combating hypothermia and regulating energy expenditure.

White Fat: Beyond Energy Storage
White fat, or white adipose tissue (WAT), is the more abundant type of fat in the human body and is primarily associated with energy storage. White fat cells store excess energy in the form of triglycerides, which can be released when energy is needed. However, recent research has shown that white fat can exhibit properties similar to brown fat through a process called browning or beiging. Browning involves the activation of UCP1 in white fat cells, leading to increased thermogenesis and energy expenditure. This discovery has opened up new possibilities for harnessing the potential of white fat in weight management and metabolic health.

Ketones: Fueling the Metabolic Fire
Ketones, specifically beta-hydroxybutyrate (BHB), have garnered attention for their impact on fat metabolism and uncoupling in white fat. During periods of low carbohydrate availability, such as fasting or adherence to a ketogenic diet, the body produces ketones as an alternative fuel source. Ketones can enhance uncoupling in white fat by increasing UCP1 expression, improving mitochondrial function, and activating specific signaling pathways. This process promotes thermogenesis and energy expenditure in white fat cells, potentially contributing to weight loss and metabolic health benefits associated with ketogenic diets.

Metabolic Flexibility and Health Implications
Understanding the intricate interplay between brown fat, white fat, and ketones provides insights into metabolic flexibility and its impact on health. Activating brown fat and promoting browning of white fat can increase energy expenditure, potentially assisting in weight management and combating obesity. Additionally, the utilization of ketones as an alternative fuel source offers metabolic advantages, such as improved mitochondrial function and uncoupling in white fat, which may have implications for metabolic health and conditions such as diabetes and cardiovascular disease.

Conclusion:
The exploration of brown fat, white fat, and the influence of ketones on fat metabolism has unveiled exciting possibilities for understanding energy balance, thermogenesis, and metabolic health. The ability to activate brown fat, induce browning of white fat, and harness the power of ketones could provide new avenues for managing weight, improving metabolic health, and combating metabolic disorders. As research in this field continues to evolve, we are gaining a deeper understanding of the intricate mechanisms that govern our metabolism and pave the way for innovative strategies in promoting a healthier future.

Essential Fat and Protein Sources for Vegans and Vegetarians on a Keto Diet

By Stephen Fitzmeyer, MD

Introduction: Following a ketogenic diet as a vegan or vegetarian can be challenging, as the focus on high fat and low carb intake requires careful consideration of food choices. However, with a wide range of nutrient-dense options available, it is possible to meet your fat and protein needs while adhering to a plant-based keto lifestyle. In this article, we will explore the best sources of fat and protein for vegans and vegetarians, with a special emphasis on keto-friendly choices.

Avocado: Nature’s Creamy Powerhouse (Keto-friendly) Avocado, the beloved green fruit, is not only a keto-friendly option but also a nutritional powerhouse. Packed with healthy monounsaturated fats, avocados provide a rich and creamy texture to dishes. They are also a source of dietary fiber, vitamins, and minerals, making them an excellent addition to a vegan or vegetarian ketogenic diet.

Nuts and Seeds: Crunchy Delights (Keto-friendly) Nuts and seeds are versatile and satisfying options for obtaining both healthy fats and protein. Almonds, walnuts, cashews, chia seeds, flaxseeds, and hemp seeds are all keto-friendly choices. These crunchy delights are not only great for snacking but can also be incorporated into recipes, such as nut butters or as toppings for salads and smoothies.

Nut and Seed Butters: Spreads of Goodness (Keto-friendly) Nut and seed butters, such as peanut butter, almond butter, and tahini, are delectable spreads that offer a generous dose of healthy fats and protein. They can be enjoyed on their own, added to smoothies, used as a dip for vegetables, or incorporated into keto-friendly baking recipes.

Coconut and Coconut Oil: Tropical Treasures (Keto-friendly) Coconut and its derivatives are keto-friendly options that bring a tropical twist to your meals. Coconut meat, coconut oil, and coconut milk are rich in healthy fats and can be used in various keto recipes, from curries to smoothies. Coconut milk, with its creamy texture, can be a great base for vegan ketogenic dishes.

Olive Oil: Liquid Gold (Keto-friendly) Olive oil, a staple in the Mediterranean diet, is a source of heart-healthy monounsaturated fats. It is ideal for cooking or as a dressing for salads and vegetables, adding flavor and healthy fats to your meals.

Plant-Based Oils: A Flavorful Spectrum (Keto-friendly) Other plant-based oils, such as avocado oil, flaxseed oil, and sesame oil, offer a diverse range of flavors and are excellent sources of healthy fats for a vegan or vegetarian keto diet. These oils can be used for sautéing, roasting, and dressing to enhance the taste and nutritional profile of your dishes.

Legumes: Protein Powerhouses While not strictly keto-friendly due to their higher carb content, legumes such as beans, lentils, and chickpeas are still valuable sources of plant-based protein for vegans and vegetarians. They can be included in moderation, considering individual carb limits and dietary preferences.

Tofu and Tempeh: Plant-Based Protein Staples Tofu and tempeh, derived from soybeans, are versatile plant-based protein sources. They can be used in a variety of dishes, including stir-fries, salads, and curries. These options provide protein while keeping carbohydrate intake relatively low, making them suitable for a vegan or vegetarian keto diet.

Seitan: Meaty Texture, Plant-Based Protein Seitan, made from wheat gluten, is a high-protein option for those following a vegan or vegetarian keto diet. With its meaty texture and ability to absorb flavors, seitan is a versatile ingredient that can be used to create delicious and satisfying plant-based dishes.

Quinoa: The Complete Protein Grain Quinoa, though higher in carbs compared to other options, is a complete protein source that contains all essential amino acids. While it should be consumed in moderation on a ketogenic diet, quinoa can be a nutritious addition to a vegan or vegetarian keto meal plan when carefully portioned.

Conclusion: Maintaining a well-rounded vegan or vegetarian ketogenic diet requires careful consideration of fat and protein sources. Fortunately, there is a wide array of options available that cater to these needs. Avocado, nuts, seeds, coconut, olive oil, plant-based oils, legumes in moderation, tofu, tempeh, seitan, and quinoa (in limited amounts) offer a range of essential fats and protein for individuals following a plant-based keto lifestyle.

Remember to personalize your food choices according to your specific dietary goals and preferences. Consult with a healthcare professional or registered dietitian to ensure that your nutrient intake aligns with your needs and to optimize your health while following a vegan or vegetarian ketogenic diet. Embrace the diversity of these plant-based options, and enjoy the benefits of a well-balanced and nourishing diet.
