The Diary Of A CEOKey Moments
Insulin resistance is a hidden epidemic linked to most chronic diseases. Control carbs, prioritize protein, and don't fear fat to lower insulin, shrink fat cells, and improve overall health.
Key Insights
Insulin resistance is the common metabolic core of most chronic diseases, including Alzheimer's, heart disease, type 2 diabetes, and infertility.
Insulin resistance involves two parts: cells becoming 'deaf' to insulin's signals and chronically elevated insulin levels in the blood.
Fast insulin resistance is caused by stress, inflammation, and too much insulin, while slow insulin resistance is driven by excessively large fat cells, primarily influenced by high insulin and calories.
A ketogenic diet, by keeping insulin low, can increase metabolic rate, promote fat burning, protect muscle tissue, and enhance brain function via ketones.
Many modern medical approaches, such as severe calorie restriction or weight loss drugs (GLP-1 agonists), can have significant downsides like muscle and bone loss, and do not address the root cause of insulin resistance.
Four pillars for combating insulin resistance are: controlling carbohydrates, prioritizing protein, not fearing fat, and frequently fasting, with muscle-building exercise providing additional benefits.
THE PERVASIVE IMPACT OF INSULIN RESISTANCE
Insulin resistance is identified as the underlying metabolic core for a vast array of chronic diseases, ranging from Alzheimer's, often dubbed 'type 3 diabetes' or 'insulin resistance of the brain,' to heart disease, type 2 diabetes, fatty liver disease, and common forms of infertility like erectile dysfunction and PCOS. Astonishingly, 88% of adults in the US exhibit some degree of insulin resistance, yet many remain unaware. This widespread issue is not merely a consequence of obesity but a fundamental physiological dysfunction where the body's cells become unresponsive to insulin, leading to elevated insulin levels that drive disease.
UNDERSTANDING INSULIN AND INSULIN RESISTANCE
Insulin, a hormone produced by the pancreas, orchestrates how every cell in the body processes energy, most notably blood glucose. Normally, insulin acts as a 'taxi' to transport glucose into cells, primarily muscle and fat. Insulin resistance is a two-fold problem: cells like muscle become 'deaf' to insulin's signals, not allowing glucose to enter efficiently. Simultaneously, the pancreas compensatory produces more insulin, resulting in chronically high blood insulin levels. This paradox means insulin is both ineffective at its job and overly present, leading to a cascade of metabolic dysregulation throughout the body.
FAST AND SLOW PATHWAYS TO INSULIN RESISTANCE
Insulin resistance can develop through two main pathways. The 'fast lane' is rapidly induced (within hours) and reversible by factors like stress (elevated cortisol and adrenaline), inflammation (e.g., from infections or autoimmune diseases), and high insulin itself. Chronic stress and inflammation force insulin to work harder, fostering resistance. The 'slow lane' is a more gradual process, primarily driven by the excessive growth of fat cells, a state prolonged by diets high in carbohydrates, leading to constant insulin elevation. This chronic high insulin signal continuously prompts fat cells to expand, eventually making them resistant to further growth signals.
THE ROLE OF FAT CELL SIZE AND ETHNICITY
The critical factor in slow insulin resistance is not merely the total mass of fat but the size of individual fat cells. Smaller fat cells are metabolically healthy and insulin-sensitive, whereas larger fat cells become inflammatory and insulin-resistant. Ethnicity plays a significant role in fat cell quantity and distribution; for instance, East Asians typically have fewer fat cells than Caucasians, meaning their existing fat cells expand more rapidly under metabolic pressure, leading to earlier onset of metabolic diseases even at lower body fat percentages. Visceral fat (around organs) is particularly detrimental, driving insulin resistance more aggressively than subcutaneous fat.
CALORIES, INSULIN, AND FAT CELL REGULATION
The conventional wisdom that obesity is solely a matter of 'calories in, calories out' is challenged. Insulin plays a pivotal role in regulating fat cell growth. In the absence of insulin, even massive caloric intake will not lead to fat gain, as evidenced by individuals with type 1 diabetes who skip insulin injections to lose weight (diabulimia). Laboratory studies show fat cells only grow larger when insulin is added to their caloric environment. Thus, insulin is necessary to signal fat cells to store energy, while calories provide the material. Controlling insulin, not just calories, is crucial for fat cell reduction.
EVOLUTIONARY PERSPECTIVES AND BRAIN HEALTH
Evolutionary theories, such as the 'expensive tissue hypothesis,' suggest human ancestors transitioned to meat-heavy diets, leading to shorter intestines and larger, more complex brains fueled by nutrient-dense foods and ketones. Ketones are an exceptional brain fuel, even preferred over glucose in certain conditions. Physiological insulin resistance during puberty and pregnancy is beneficial, promoting growth and energy storage for development. Pathological insulin resistance in the brain, however, is linked to an energetic deficit that contributes to conditions like Alzheimer's, depression, migraines, and epilepsy, which all exhibit 'brain glucose hypometabolism'.
ALZHEIMER'S DISEASE: A METABOLIC DISORDER
Alzheimer's disease, now a top-10 killer, is increasingly understood as a metabolic disorder—specifically, insulin resistance of the brain. The long-standing 'plaque-based theory' where protein plaques cause cognitive decline has been largely discredited. Instead, regions of the Alzheimer's brain struggle to utilize glucose due to insulin resistance, creating an energy gap. If ketones are not available to fill this gap, cognitive function declines. Studies show a significant correlation between insulin resistance and Alzheimer's, highlighting the importance of metabolic health, including adequate ketone production, for brain function.
MEASURING AND ADDRESSING INSULIN RESISTANCE
Accurately measuring insulin resistance often requires checking blood insulin levels directly, which is not routinely done in many healthcare systems. An insulin level above 10 micro units/mL (or 40 picamoles in UK units) indicates a warning. Importantly, insulin resistance can exist even in lean individuals, particularly in certain ethnicities like East Asians or those with conditions like PCOS. The approach to addressing it must be comprehensive, as seen in the benefits derived from a ketogenic diet, which lowers insulin and promotes metabolic flexibility.
KETOSIS: FUELING THE BODY AND BRAIN
Ketosis is a metabolic state where the body primarily burns fat for fuel, producing ketones as a byproduct in the liver when insulin levels are low for an extended period (around 16+ hours). Ketones are a superior fuel for the brain, enhancing cognitive function and potentially reversing neurological deficits in early Alzheimer's. Beyond brain benefits, ketosis can triple the metabolic rate of fat tissue, protect muscle from injury, and increase overall metabolic rate, promoting efficient fat loss. Elite athletes increasingly use ketone supplements to enhance endurance and performance.
DOWNSIDES OF KETOGENESIS AND THE MICROBIOME
While beneficial, a ketogenic diet can temporarily reduce metabolic flexibility, making it slower to process carbohydrates if reintroduced. Concerns about the gut microbiome lacking diversity due to reduced plant intake are often overstated; scientific evidence suggests no harmful changes, and some studies even show stability. The focus should remain on overall human health outcomes, which include improved insulin sensitivity, weight loss, and enhanced cognition, rather than speculative negative impacts on microbiome diversity.
THE FOUR PILLARS FOR LOWERING INSULIN
To combat insulin resistance and promote health, Dr. Bikman outlines four simple yet powerful pillars: 1. Control carbohydrates: Prioritize whole fruits and vegetables, avoiding processed carbs from bags and boxes. 2. Prioritize protein: Focus on animal-sourced proteins for essential amino acids. 3. Don't fear fat: Healthy fats, especially when combined with protein, are satiating and crucial for muscle growth. 4. Frequently fast: Once the first three pillars are established, structured fasting helps maintain low insulin levels and encourages fat burning.
THE CRITICAL ROLE OF EXERCISE AND CHALLENGING DIETARY DOGMA
Exercise is a vital component of managing insulin sensitivity, with muscle-building activities being particularly effective as muscle is the primary consumer of glucose. Contracting muscles can absorb glucose without insulin, thus buffering blood sugar levels. Strength training and muscle mass are stronger predictors of longevity than aerobic fitness. The traditional advice to 'eat less, exercise more' often fails because it ignores the hormonal regulation of hunger and fat storage. Instead, focusing on insulin reduction naturally reduces hunger and promotes a higher metabolic rate.
ARTIFICIAL SWEETENERS AND ENVIRONMENTAL FACTORS
Artificial sweeteners vary in their metabolic impact. Some, like aspartame, erythritol, monk fruit, stevia, and allulose, appear to have no effect on insulin. Others, particularly some sugar alcohols (e.g., maltitol, mannitol), can elicit an insulin response and cause digestive issues. Sucralose can cross the blood-brain barrier, raising some concerns. Environmental factors also contribute to insulin resistance; diesel exhaust particles and microplastics can promote fat cell growth and inflammation, further challenging the simplistic 'calories in, calories out' model of obesity.
THE DANGERS OF MODERN WEIGHT LOSS DRUGS AND LIPOSUCTION
GLP-1 receptor agonists (e.g., Ozempic) promote satiety and weight loss but come with significant negative side effects. Studies reveal that up to 40% of the weight lost on these drugs comes from lean mass, including muscle and bone, potentially leading to osteoporosis. There's also an increased risk of suicidal thoughts and severe depression. While they can aid in breaking carbohydrate addiction at low doses, reliance on these drugs without lifestyle changes can lead to severe health consequences. Similarly, liposuction provides temporary aesthetic changes but does not improve metabolic health and can lead to fat redistribution to more dangerous visceral areas, worsening long-term health outcomes by removing healthy fat cells and increasing the burden on remaining ones.
