Every day, the way you're eating impacts your glucose levels and dictates how quickly you're aging. Two effective hacks to avoid blood sugar spikes are: 1. **Vinegar Before Meals**: Drink a tall glass of water with one teaspoon to one tablespoon of vinegar (not balsamic) before meals. This can decrease glucose spikes by up to 30%, leading to less inflammation, weight gain, and cravings. 2. **"Clothing" Your Carbs**: Always pair carbohydrates with protein, fat, or fiber to slow glucose absorption. For example, add butter to bread or nuts to cookies. This prevents sharp glucose spikes and allows you to enjoy carbs without negative effects. Understanding the effects of food on your body is crucial. Many people don’t realize that their food choices directly affect their energy levels, cravings, and overall health. For instance, glucose spikes can lead to increased hunger and weight gain due to hormonal fluctuations. Glucose is the body’s preferred energy source, but spikes can cause inflammation and other health issues. Most people experience daily glucose spikes, often without realizing it. By applying simple hacks, individuals can improve their health and manage their blood sugar levels effectively. The book "Glucose Revolution" emphasizes that food choices significantly affect both short-term and long-term health, including risks for chronic diseases like cancer. High glucose levels can lead to inflammation, which is linked to various health issues. Eating habits, such as consuming sweets after meals rather than as snacks, can help manage glucose levels. Additionally, the order of food consumption matters; starting with vegetables can mitigate glucose spikes from starches. Cultural practices, like eating vegetables first or walking after meals, have been shown to support better glucose management. Ultimately, small, manageable changes in diet can lead to significant improvements in health and well-being, making it easier to maintain a balanced lifestyle.

Three macronutrient-based rules govern carbohydrate intake: avoid processed carbs, prioritize whole fruits and vegetables, and focus on protein and fat. Insulin resistance is the foundation of type 2 diabetes, which can be reversed through dietary changes rather than medication. A study showed that 11 women with diagnosed type 2 diabetes reversed their condition in 90 days through a dietary intervention aimed at lowering insulin without medication. To reduce insulin levels, fasting is the most effective method, as it allows insulin to drop quickly. When eating, focus on fats and proteins to keep insulin low. The conventional dietary paradigm, which emphasizes carbohydrates, is flawed; humans do not need essential carbohydrates. Instead, prioritize nutrient-dense animal proteins and healthy fats. Insulin resistance develops when fat cells become hypertrophic, leading to the release of free fatty acids and pro-inflammatory molecules that disrupt insulin signaling. To combat this, a low-insulin approach—controlling carbohydrates and prioritizing protein and fat—is recommended. Meal timing is also crucial; eating earlier in the day is more beneficial for metabolic health.

Weight loss and improving insulin sensitivity are interconnected. Dr. Ben Bikman emphasizes the importance of having a dietary plan before starting fasting. He warns against jumping into extreme fasting methods like OMAD (one meal a day) without proper preparation, which can lead to binge eating on unhealthy foods. The way one breaks a fast is crucial; it should involve foods that do not spike insulin levels. Bikman critiques common breakfast choices, particularly sugary fruits and fruit juices, which can lead to insulin spikes. He advocates for a diet that controls carbohydrates, prioritizes protein, and does not fear fat. He shares his personal eating routine, emphasizing strictness with breakfast and lunch while being more flexible at dinner to maintain family dynamics. He discusses the physiological insulin resistance experienced during pregnancy and puberty, contrasting it with pathological insulin resistance, which leads to health issues. Bikman highlights the importance of insulin in fat metabolism and the need for a balanced approach to dieting that includes both controlling insulin and managing caloric intake. He shares insights from a study showing that lower carbohydrate diets can increase fat cell metabolic rates. The conversation concludes with a focus on the importance of community in eating habits and the need for personalized dietary approaches. Bikman encourages awareness of how food choices impact metabolic health and overall well-being.

In this episode of The Diary of a CEO, Steven Bartlett welcomes Benjamin Bikman, a leading metabolic scientist, to dissect how insulin orchestrates weight gain and how carbohydrate restriction and ketosis can reshape energy balance. The guest dispels the oversimplified “eat less, move more” paradigm, arguing that insulin’s role in energy storage is the pivotal lever for fat loss. He explains that two variables drive fat loss: shrinking fat cells and lowering insulin by reducing carbohydrate intake. The discussion traverses how insulin spikes suppress the brain’s access to energy from glucose and ketones, triggering hunger even when fat stores are plentiful. Bikman emphasizes that fat loss should come from protocols that minimize hunger and energy scarcity, highlighting that meals with the same calorie count but different macronutrient compositions yield different metabolic rates due to insulin’s regulation of energy use. He connects ketosis not only to fat burning but to diverse brain benefits, including reduced anxiety and improved attention, and shares how ketones serve as both fuel and signaling molecules that influence blood vessel dilation and brain chemistry. The conversation moves from practical diet design—structured indulgences around carb-rich holidays, prioritizing protein and fat to keep insulin low, and leveraging exogenous ketones during transitions—to the nuance of insulin’s supremacy in fat metabolism, illustrated with clinical anecdotes about type 1 diabetes and insulinoma to underscore how insulin control shapes outcomes. The host and guest explore the potential of breastfeeding-like clarity in patient education while acknowledging the complexities of real-world adherence, social media scrutiny, and evolving scientific discourse. Bikman also delves into the therapeutic potential of ketones for neurological and cardiovascular health, the role of exogenous ketones in preserving lean mass during weight loss, and the possibility of using GLP-1 therapies in a cycle with low-carb coaching to sustain long-term changes. They close with practical daily frameworks, including fasting, big lunch planning, regular resistance training, sleep optimization, and the impact of stress and testosterone on metabolic health, offering a holistic blueprint for listeners seeking a healthier 2026.

Excess belly fat, or visceral fat, is linked to serious health issues, including cardiovascular and neurological problems. It secretes hormones and inflammatory cytokines that can affect overall health. To lose belly fat, focus on diet and activity levels, prioritizing protein and whole foods, which are more satiating. Managing stress is also crucial, as chronic stress elevates cortisol, influencing fat distribution. Sustainable weight loss involves a moderate calorie deficit and healthy habits.

Insulin plays a crucial role in fat cell dynamics; it must be elevated for fat cells to grow and low for them to shrink. Dr. Benjamin Bickman, a metabolic research scientist, emphasizes the importance of understanding insulin resistance, which affects fat burning, longevity, and chronic disease risk. Many people unknowingly suffer from insulin resistance despite believing they eat healthily. Bickman’s book, *Why We Get Sick*, explores reversing insulin resistance and improving overall health. Bickman discusses a pivotal study that revealed fat cells as active endocrine organs that release hormones influencing distant body cells. Misconceptions about fat cells being inert are common; they actively regulate energy storage and release based on insulin levels. Elevated insulin leads to fat accumulation, while low insulin allows fat loss. Fat cells also secrete hormones like leptin, which regulates hunger and fertility, linking obesity to metabolic diseases. The traditional advice of "eat less, exercise more" fails because it overlooks hormonal factors, particularly insulin. Bickman argues that focusing on insulin management is more effective for weight loss than calorie counting. Insulin resistance is often undetected until glucose levels rise, leading to misdiagnosis and ineffective treatments. Bickman identifies signs of insulin resistance, including excess belly fat and skin tags. He recommends dietary changes to lower insulin levels: controlling carbohydrate intake, prioritizing high-quality animal protein, consuming healthy fats, and practicing intermittent fasting. Stress management, particularly through improved sleep, is also vital for reducing insulin resistance. Bickman advocates for using continuous glucose monitors (CGMs) to empower individuals to make informed dietary choices. His insights highlight the need for a paradigm shift in understanding metabolic health, emphasizing insulin's role over glucose alone.

In a discussion about dietary approaches, Ben Bikman emphasizes the relationship between insulin, fat storage, and weight management. He notes that while some individuals on strict carnivore or low-carb diets may experience weight gain, this is often due to pre-existing insulin resistance or high insulin levels rather than the diet itself. Bikman explains that high insulin promotes fat storage, regardless of calorie intake, and that addressing insulin levels is crucial for effective weight loss. He highlights the importance of understanding fasting insulin levels, suggesting that a level below 6 micro units per milliliter indicates good insulin sensitivity. He argues that fasting insulin is a more critical marker of metabolic health than glucose levels, which can remain normal even as insulin resistance develops. Bikman advocates for a dietary approach that prioritizes controlling carbohydrates, emphasizing protein intake, and not fearing dietary fats, as these strategies can help lower insulin levels and improve metabolic health. Bikman also discusses the role of muscle mass in metabolic health, noting that increased muscle can enhance insulin sensitivity and aid in glucose management. He warns against calorie counting as a primary strategy for weight loss, arguing that it often leads to failure due to the body's complex energy regulation mechanisms. Instead, he suggests that individuals should focus on reducing insulin levels first, which can naturally lead to weight loss without the constant struggle of calorie restriction. He acknowledges the challenges of dietary changes, particularly for those with deep-seated habits or emotional connections to food. Bikman encourages individuals to find a balance that works for them, emphasizing the importance of whole foods over processed options. He also touches on the societal issues surrounding obesity, suggesting that a lack of community and connection contributes to poor dietary choices and health outcomes. In conclusion, Bikman advocates for a holistic approach to health that includes dietary adjustments, physical activity, and fostering social connections, all while maintaining a focus on insulin management as a key to achieving and sustaining metabolic health.

Visceral fat is not merely about looks; it’s a gateway to inflammation, insulin resistance, and heart disease, and a growing medical approach centers on fasting as the fastest route to shed it. A world-leading cardiologist with decades of experience explains how repeated carb intake keeps insulin high, promotes visceral fat, and fuels artery disease. He emphasizes that after about 12 hours of fasting, the body begins pulling stored fat from the belly first, a process he uses to reverse metabolic derangements. The conversation then shifts to how modern living disrupts fasting physiology, contributing to a cascade of inflammatory signals, fatty liver, and a skewed lipid profile that can culminate in heart attacks even in younger patients. He maps a chain from gut health to heart disease, highlighting how insulin-driven visceral fat and ectopic fat around organs inflame blood vessels. A key diagnostic thread is insulin testing, because many patients exhibit high insulin with normal glucose, a sign of insulin resistance that predates diabetes and accelerates cardiovascular risk. Fasting emerges as a powerful instrument: from 12-hour fasts to 18:6 schedules, with more aggressive regimens for those with diabetes or obesity, such as weekly 48-hour fasts or occasional three-day water fasts, followed by one meal a day. He also notes that ketosis and autophagy make cells more efficient, produce ketones as fuel, and can boost brain function and growth hormone, while the body cycles between fed and fasted states to preserve muscle when properly managed. The discussion then turns to the gut as the main driver of cardiovascular inflammation. A disrupted microbiome, leaky gut, and mold exposure are described as contributors to fatty liver and coronary plaque, with the liver and gut coordinates measured by inflammatory markers and coronary calcium scoring. Rebalancing the microbiome—through high-fiber diets, fermented foods, and specific prebiotic supplements—can dampen systemic inflammation and slow plaque progression. He advocates vitamin D3 and K2 to optimize calcium handling, cautions against routine calcium supplements, and endorses omega-3s and nattokinase to modulate clotting. Beyond diet, he explains vagus nerve hacks—breathing exercises, cold exposure, humming, and even eye movements—that enhance parasympathetic activity, improve heart rate variability, and support gut-brain communication. He stresses that sleep and stress management are essential for gut health and heart protection.

Dhru Purohit hosts a discussion with Rangan Chatterjee, Ben Bikman, and Shawn Stevenson on sustainable weight loss and health improvement strategies that move beyond traditional calorie-centric paradigms. Rangan emphasizes that sustainable weight loss can be achieved without drastic dietary changes by focusing on factors such as hunger, eating environment, and timing. He critiques the long-standing belief that weight loss is solely about caloric deficit, arguing that this approach often leads to yo-yo dieting due to constant hunger and deprivation. He introduces the importance of insulin in weight management, explaining that fat cells cannot grow without elevated insulin levels and cannot shrink unless insulin is low. Rangan advocates for prioritizing the endocrine component, particularly insulin management, over calorie counting, which can be tedious and frustrating. He explains that insulin is produced by the pancreas and plays a crucial role in lowering blood glucose levels after carbohydrate consumption. However, chronic high insulin levels can lead to insulin resistance, a condition affecting a significant portion of the population, particularly in Western countries. The conversation also touches on the relationship between insulin resistance and various health issues, including erectile dysfunction, hypertension, and neurological disorders like migraines and Alzheimer's disease. Rangan highlights that insulin resistance can stem from dietary choices and stress, emphasizing the need for a holistic approach to health that includes emotional well-being and stress management. The discussion further explores the role of the microbiome in metabolism and weight regulation, noting that gut diversity is linked to obesity. Rangan shares insights from studies showing that specific gut bacteria can influence calorie absorption and body composition. He stresses the importance of a diverse diet rich in whole foods to support gut health. The hosts also discuss the psychological aspects of eating, emphasizing that emotional factors often drive unhealthy eating behaviors. Rangan introduces the "three F's" exercise to help individuals understand their feelings around food and find non-food alternatives to address emotional needs. Finally, the conversation underscores the interconnectedness of food, health, and relationships, highlighting how nutritional deficiencies can impact emotional stability and interpersonal dynamics. The hosts call for a shift in focus from mere calorie counting to a more nuanced understanding of health that incorporates emotional, psychological, and physiological factors.

America is getting fatter, and while diet debates dominate, this stream emphasizes root mechanisms. Sleep deprivation is presented as a major driver, tied to circadian rhythm and hormones that decide whether energy is stored or burned. The speaker describes the endocrine system as glands that secrete hormones to regulate metabolism, with receptive tissues adjusting energy use in real time. He contrasts the two autonomic branches—parasympathetic 'rest and digest' and sympathetic 'fight or flight'—and stresses that balance is a continual readjustment, not a fixed state. Insulin anchors the fat story. 'Insulin is the chief executive of storing fat. Insulin is the fat storing hormone.' It regulates blood glucose, but its action includes storing energy as glycogen. The hunger hormones ghrelin and leptin figure into appetite control; leptin is triggered by distension of the GI tract as food fills the stomach. The 'dial' model is introduced: nothing in the body is simply on or off; processes run along a continuum with amplifications and inhibitions. Insulin resistance is explained with a dull knife analogy: tissues stop listening, so more insulin is needed, risking hyperinsulinemia and hyperglycemia. Sleep timing and circadian alignment are central. Circadian rhythm is the 24-hour cycle guiding hormone release; the sun’s cycle is the master signal. The talk highlights 'money time sleep'—the deep sleep window around 10 p.m. to 2 a.m.—as a key recovery period. Slow wave sleep is described as playing the most important role in metabolic, hormonal, and neurophysiological changes. Disruptions to timing—late-night light, screens, shift work—throw leptin, ghrelin, and insulin off balance, increasing appetite and promoting weight gain. Evidence is presented. An interventional study shows partial sleep restriction for a single night reduces insulin sensitivity by 19 to 25% for hepatic and peripheral glucose metabolism. Observational meta-analysis across nine studies finds short sleep (often five hours or less) raises relative risk of type 2 diabetes; for example one sample shows 1.19 times the risk, another reports up to 180% increase in some comparisons, and seven hours or less yields mixed results. Averaging across studies, short sleep is linked to about a 28% increased risk of type 2 diabetes versus eight hours. Practical takeaways emphasize sleep hygiene: remove phones from the bed, keep the room dark and cool, and limit blue light exposure; blue light blocking glasses are discussed as partially effective and partly a cash grab. The sun remains the reliable regulator; timing aligned with the sun sustains hormonal balance. Chronotypes and sleep quality versus duration are acknowledged. The narrator urges practical steps to improve sleep and notes that improving sleep timing can support metabolic homeostasis and potentially aid weight management, without becoming obsessively anxious about every moment of sleep.
