The Dr. Berg Show LIVE - October 23, 2026
In a Nutshell
Dr. Berg recommends prolonged fasting combined with low-carb eating to reverse visceral fat accumulation in the liver and around the heart, which drives insulin resistance and metabolic disease. Key interventions include 3/4-1 teaspoon of sodium daily during fasting, 8,000+ IUs of vitamin D3 with blood level monitoring between 50-80 ng/mL, and addressing underlying causes rather than symptoms for conditions like depression, nocturia, and hypothyroidism. Natural health rhythms—alternating eating with fasting, exercise with rest, and light with darkness—are presented as the fundamental solution to chronic disease over screening protocols or pharmaceutical interventions.

Dr. Berg opens the Q&A session with a standard disclaimer that nothing said is intended to cure anyone. Viewers should check with their doctor before implementing any suggestions.
Dawn from YouTube asked whether MASH (metabolic dysfunction-associated steatohepatitis, formerly known as non-alcoholic fatty liver disease) could cause elevated blood sugar and A1C levels. The condition involves the liver becoming overloaded with refined carbohydrates and sugars, leading to fat accumulation within the liver itself. This creates insulin resistance in the liver tissue. Once the liver becomes saturated with fat, excess fat spills over into other organs and tissues, including around the heart. The recommended approach combines a low-carb diet with prolonged fasting to remove fat from the liver and improve insulin resistance. Exercise helps address insulin resistance that may also develop in muscle tissue.
Michelle from YouTube asked whether 1.5 teaspoons of salt per day is sufficient during keto and 20-24 hour fasting. The recommendation is a minimum of 3/4 to 1 teaspoon of salt daily if consuming no-salt foods, unless sweating heavily. For prolonged fasting, approximately 1 teaspoon total is recommended, divided into four portions spread throughout the day, consumed in water or placed directly in the mouth. During a 24-hour fast, the body loses approximately half of its sodium through urine. Additionally, 1,000-1,500 milligrams of potassium are lost during fasting, requiring a high-potassium electrolyte powder.
Linda from YouTube asked whether creatine monohydrate powder and multicolagen peptide powder can be taken simultaneously. There are no drawbacks to combining them. The only consideration is taking them early in the day, as they may provide a slight energy boost.
Ako from YouTube asked about daily vitamin D1 requirements for optimal health. The question was clarified to refer to vitamin D3. There is no consensus on dosage recommendations. The previous recommendation of 800 IUs was revised upward to 8,000 IUs, though this change was not widely communicated to the public. A minimum of 8,000 IUs is suggested, with some individuals taking 10,000 IUs or more. The key metric is blood levels rather than intake amount, as vitamin D enters the blood in inactive form. Target blood levels should be maintained between 50-80 nanograms per milliliter. Testing blood levels after starting with 8,000 IUs allows for dosage adjustment based on individual response.
Steve mentioned taking 10,000 IUs daily with blood work showing levels on the high side of normal. Toxicity concerns are addressed by noting that hundreds of thousands of IUs would need to be consumed for months before problems develop. Protective factors include vitamin K2, zinc, and magnesium supplementation, along with blood monitoring for elevated calcium. The risk of kidney stones represents the primary toxicity concern. The damage from insufficient vitamin D is considered significantly greater than the rare occurrence of toxicity.
Captiva Son from YouTube asked about treating complex PTSD. Recommended interventions include long walks in nature with sun exposure, reducing cell phone use, ensuring adequate rest, taking B1 (thiamine), following a low-carb diet to stabilize mood and cognitive function, and implementing prolonged fasting episodes of 48 hours approximately every two weeks. Prolonged fasting has significant effects on brain function and mood improvement.
Steve shared his personal experience that prolonged fasting resolves his depression symptoms. Eating poorly causes him to suffer for several days afterward. He emphasizes that the discipline around fasting and dietary choices stems primarily from managing depression rather than weight or health marker improvements.
True or false: Visceral fat is the slowest fat to get rid of. The answer is false. Visceral fat is the fastest fat to lose from the body, appearing first when implementing low-carb eating and fasting protocols. Subcutaneous fat (the layer directly beneath the skin) is lost last. Initial weight loss during fasting is often water weight that returns upon refeeding, but visceral fat reduction is permanent and measurable via MRI of the heart and liver within days. Visceral fat produces inflammatory and hormonal effects that increase insulin resistance and contribute to chronic disease.
Donna from YouTube asked about reversing receding gums and rapid muscle loss. Recommendations include increased protein intake, particularly animal protein containing leucine, combined with weight training. Postmenopausal women require additional effort for muscle growth and should continue weight training regardless of age. Collagen supplementation supports gum health, along with adequate vitamin C for collagen formation.
Camilo from YouTube asked how to increase pancreatic enzymes despite normal MRI and CAT scan results. Symptoms of low pancreatic enzymes include dark tar stools (due to insufficient lipase) and incomplete digestion. The pancreas has dual functions: producing digestive enzymes and producing insulin/glucagon for blood sugar regulation. A history of poor diet may affect both functions. Low-carb eating combined with periodic prolonged fasting is recommended. Caution is advised regarding diagnosis accuracy, as misdiagnosis is common in medicine.
Nurse ER from YouTube asked about slowing Parkinson's progression and increasing mitochondrial ATP production. Parkinson's is characterized as a metabolic disease requiring a healthy low-carb diet, intermittent fasting, and multiple nutrients rather than single-vitamin approaches. Exercise, including weight training and zone 2 cardio, increases mitochondrial production. The concept of actively creating health daily is emphasized over merely preventing disease.
Susan from YouTube asked about acupuncture. It is considered a valid therapy that has been practiced for thousands of years, with personal experience cited as positive.
Rea from Facebook asked about caffeine sources for her daughter in medical school who needs to stay awake longer. The intensive memorization demands of medical education are acknowledged as problematic. The recommendation is to obtain energy from a healthy keto diet with adequate animal protein rather than relying on caffeine. Seven hours of sleep is emphasized as essential to prevent burnout. The cautionary example of consuming excessive Cuban coffee during premed studies is shared.
Pasa from Rumble asked whether microwaving food depletes nutrients. The effect on nutrients is not considered significant. However, concerns exist about plastic containers leaching into food during microwaving. The speaker no longer uses a microwave as part of broader health optimization efforts.
What is the single best way to eliminate headache, irritability, weakness, and hunger during prolonged fasting? The answer is sodium. During the first day of fasting, approximately 50% of body sodium is lost. Drinking plain water without sodium dilutes remaining sodium further, causing these symptoms. Preemptive sodium consumption prevents the transition difficulties between glucose and fat burning, which occurs around 24 hours but may extend to 48 hours in those with metabolic dysfunction. Potassium supplementation is also recommended due to its role in the sodium-potassium pump.
Stacy from Facebook asked about primary causes of zinc deficiency. Symptoms include altered smell and taste, night blindness (due to impaired vitamin A function), weakened immune system, reduced testosterone, and decreased vitamin D absorption.
Sashi01 from Rumble asked whether low cortisol makes fasting more difficult. This question was deferred for later discussion.
Lou from YouTube asked how to support a 9-year-old on oral antibiotics. Preference is given to narrow-spectrum antibiotics over broad-spectrum when possible, as they have fewer side effects. Probiotics should be taken concurrently with antibiotics. The microbiome diversity does not fully recover after antibiotic use. Regular consumption of fermented foods (sauerkraut, fermented pickles, kefir) is recommended for ongoing microbiome support.
Kelly from Facebook asked about safe daily potassium supplementation. The RDA is 4,700 milligrams, which can be safely supplemented unless on certain medications or with stage 4 kidney disease, in which case medical consultation is required.
A returning caller described symptoms including pain under the left rib cage radiating to the back, nausea, loss of appetite, black tar stools, and diarrhea following a year of increased fast food consumption and stress. Previous liver issues had been resolved with zinc carnosine. The symptoms suggest bile duct sludge affecting both gallbladder and pancreatic ducts, leading to lipase deficiency (causing dark stools) and disrupted bowel function. The pancreas location explains left-sided discomfort. The primary recommendation is eliminating junk food, with supportive remedies for bile flow.
Gabby from Rumble asked how to maximize D3 absorption during morning walks while wearing protective clothing. Maximum skin exposure is required for vitamin D production. Hats should be removed, and arms should be exposed. Even in cooler weather, some skin exposure is important. Cold exposure during walking is also beneficial.
JB Health from YouTube asked what advice would be given to a family member considering a mammogram or colonoscopy. Mammograms are not recommended. Colonoscopies extend lifespan by approximately 110 days but carry risks including perforation. Screenings generally are not favored, as they lead to additional procedures and complications. Fear from cancer diagnoses increases heart attack risk by 2.5 times. Creating health is preferred over screening protocols. PSA testing has not demonstrated increased lifespan.
Ricky from Facebook asked whether zero-calorie sodas break a fast. Artificial sweeteners in zero-calorie sodas break the fast. Only tea or black coffee are acceptable.
75% of the audience correctly identified sodium as the solution for fasting-related headache, irritability, weakness, and hunger. A person of average build has over 100,000 calories of stored fat energy, so hunger during fasting is not due to energy depletion but rather sodium depletion. The sodium-potassium pump requires both minerals, though most symptoms relate to sodium loss.
Katherine from Facebook asked about niacin for POTS (postural orthostatic tachycardia syndrome). Niacin is not considered appropriate. POTS involves autonomic nervous system dysfunction where the body fails to adapt to gravity stress. Therapeutic doses of B1 (thiamine) address this. Additionally, increasing fluid volume through sea salt and water helps maintain blood pressure and reduces dizziness upon standing.
A mailbag question addressed reducing excess iron in a daughter's blood (borderline high, hereditary, no iron supplementation). Regular blood donation is the recommended approach. Iron supplements should not be started.
A 59-year-old male reports getting up to urinate as many as five times per night.
Frequent nighttime urination, sometimes occurring as many as five times, is not normal and is not 100% associated with enlarged prostate. The primary cause is elevated insulin levels from consuming too many carbs and snacking at night. Insulin retains sodium, which causes fluid retention. When lying down at night, fluid shifts upward from the lower extremities due to gravity, filling the bladder and causing urination. The solution is lowering insulin by reducing carbs. There will be a transition period where excess water is eliminated, but maintaining a low-carb diet prevents nighttime urination. Many men and women have solved this through intermittent fasting and carb reduction.
Folate, not folic acid (which is synthetic), is recommended during pregnancy to prevent neural tube defects in babies. Prenatal vitamins are typically low-quality synthetics. Natural, high-quality nutrient supplements should be used instead to support both mother and baby with essential B vitamins and minerals.
Arrowroot powder contains carbs but is safe in small amounts when used for cooking texture. It should not be consumed in large quantities.
It is possible to stop synthetic T4 after long-term use, though the body becomes dependent. Addressing the underlying cause offers a chance of success, but results cannot be guaranteed due to individual limitations.
Acid reflux and gastritis are distinct conditions. For gastritis, broccoli sprouts and cabbage (especially cabbage juice) are recommended due to vitamin U content. Zinc carnosine also helps. Testing apple cider vinegar (one teaspoon in water) can determine if acidifiers will help or worsen symptoms. If symptoms worsen, acid is not the solution; if they improve, betaine hydrochloride may help. A digestion video covers this topic in depth.
Synthetic vitamins are lab-made, often from petroleum or chemicals like cornstarch and sulfuric acid. Most synthetic vitamins are not recommended, though benfotiamine and TUDCA appear acceptable. Isolated vitamin A, D, and E may create problems. Vitamin C should be consumed as the whole complex rather than isolated ascorbic acid. During intermittent fasting, natural vitamins are preferred along with electrolytes.
Magnesium stearate is added as a flow agent in tiny amounts to facilitate manufacturing. Vegetable-sourced magnesium stearate is used in quality supplements. The quantity is insignificant compared to common dietary issues and is not a major concern.
Dry fasting can cause constipation due to lack of water intake. It should only be done under supervision from experienced practitioners and possibly medical monitoring for extended periods. Benefits exist but proper technique and gradual reintroduction are essential.
Fat accumulation around the heart is not normal. Unlike other organs, the heart lacks protective wrapping, allowing direct contact with fat. This toxic fat with low-grade inflammation contributes to atrial fibrillation and heart disease. An MRI of the heart can measure cardiac fat. Prolonged fasting is the fastest method to eliminate visceral fat, including heart-surrounding fat, which can reduce within five days. A 72-hour fast is currently being undertaken, with plans for 48-hour fasts every two weeks.
An app called Wellness Map at wellnessmap.com is being developed as a free tool to guide users through fasting protocols and monitor progress while collecting collective research data.
A 250+ page health book uses a questionnaire to identify the most significant health problem first, then guides users through related chapters. Starting with the primary issue allows gradual implementation of recommendations.
Normal calcium levels do not necessarily indicate healthy bones. Bone loss can result from menopause-related estrogen decline affecting protein, minerals, and collagen. Weight training, vibration plates, and trace minerals are recommended over calcium carbonate. Dairy provides calcium, and certain bone-building calcium forms may be appropriate alongside comprehensive bone-support nutrients.
Vitamin D levels of 140 require medical supervision from a doctor trained in the Coimbra Protocol. Blood calcium monitoring is essential. Higher levels (sometimes exceeding 250) have been used successfully for autoimmune conditions like MS under proper monitoring to overcome vitamin D resistance.
ADD symptoms often stem from high insulin, excessive carbs and sugars, and nutrient deficiencies. Addressing lifestyle factors including sleep, exercise, nutrition, and food quality is essential rather than treating symptoms with remedies alone.
Electromagnetic therapy devices showed limited personal effectiveness. Superior sleep approaches include early morning sun exposure, avoiding evening snacking, maintaining bedroom temperature at 65-68 degrees, keeping the room dark, using white noise, and maintaining consistent sleep-wake schedules.
The true enemy of chronic disease is not junk food itself but the companies profiting from chronic disease. The junk food industry designs products to prevent satisfaction. PR campaigns promoting moderation and denying bad foods represent propaganda. The sugar industry historically shifted blame to saturated fat, creating lasting misconceptions.
Ninety percent of hypothyroidism cases are Hashimoto's, an autoimmune condition rooted in gut issues rather than thyroid deficiency. Gluten consumption creates antibody mimicry and inflammatory thyroid conditions. Selenium is the most critical nutrient, alongside dietary cleanup. Iodine deficiency is not the primary cause.
Recovery support includes vitamin D optimization, exercise for brain oxygenation, ketogenic metabolism, and hyperbaric chamber therapy to increase tissue oxygen pressure for healing post-surgical compression.
Hypoxic training using altitude simulation masks ($15) during exercise or HIIT sprints restricts air intake, stimulating red blood cell production. Training should progress gradually from lower simulated altitudes.
Ancient cultures consumed dairy primarily in fermented forms like cheese, kefir, or yogurt, which reduce lactose and add beneficial bacteria. Fermented dairy is recommended over liquid milk. Dairy should be avoided by those with enlarged prostate or cancer due to growth-promoting properties, but can be consumed during regular and prolonged fasting if fermented.
PSA is an enzyme that liquefies semen gel for sperm transport, not a direct cancer marker. Nine different causes can elevate PSA levels, with cancer being the least likely. Elevated PSA often triggers unnecessary biopsies and overtreatment. Sixty percent of men in their 80s and nearly 50% of men in their 60s have prostate cancer that typically does not cause death. Cycling, deadlifting, squats, and heavy exercise can temporarily elevate PSA. False positives are common.
Collagen peptides, cloves, cinnamon, and cacao can be added to coffee. Cacao increases nitric oxide and provides polyphenols beneficial for gut microbes. Hot water slightly reduces cacao's effects, but adding it to coffee remains convenient and effective. During fasting, only black coffee is consumed.
Small intestinal bacterial overgrowth occurs when large intestine microbes ferment in the small intestine, causing distension and bloating especially with fiber intake. Treatment involves prolonged and periodic fasting, carnivore diet, betaine hydrochloride, and bile salts, which act as detergents to control bacterial overgrowth. Specific microbes like L. reuteri may also be beneficial.
Jan from YouTube asked about natural solutions for improving the ejection fraction of the heart without medications. A comprehensive natural approach includes a high-quality B complex with co-enzyme Q10 and animal protein. The most significant intervention is exercise, starting gradually and building up to higher intensity interval training. Endurance-type exercise is not recommended; instead, increased physical activity throughout the day allows the heart to respond and adapt. Periodic prolonged fasting can eliminate fat around the heart, which alone improves heart function.
Paula from Facebook inquired whether vitamin D can be obtained from an infrared sauna. Infrared light does not produce vitamin D. Only certain types of ultraviolet light can stimulate vitamin D production.
Vicki from YouTube, age 49 and perimenopausal, reported significant hair loss. Recommended supplements include vitamin D, which is important for hair health. Infrared light therapy using a specialized helmet shows promising data. For specific types of hair loss, onion juice application has documented benefits. Microneedling is another effective approach. Selenium supplementation also supports hair health.
The modern environment has collapsed natural contrasts between light and dark, creating a monotone of artificial light indoors. Snacking and eating throughout the day eliminates natural fasting periods. Lack of exercise creates a flat line of activity. People remain indoors 95% of the time. The key to restoring health lies in reintroducing natural fluctuations: periods of exercise followed by rest, eating followed by fasting. These rhythmic patterns represent the fundamental difference between health-promoting and health-damaging habits. Identifying where these natural rhythms have been disrupted in daily routines and environments reveals the core problems affecting health.
