The Real Reason You're Bloated After Eating

Berg explains that stomach acid should be extremely acidic (pH 1-3, like battery acid). As people age, acid production declines, leading to a host of digestive issues. The typical symptom of low acid is paradoxically acid reflux, because the valve at the top of the stomach doesn't close without sufficient acid. Antacids make this worse by further reducing acid. Betaine HCl tablets, taken before meals, can quickly relieve bloating and improve protein digestion. He recommends starting with 3-5 tablets and seeing if bloating clears within days; if it works, continue for weeks until symptoms resolve, then try reducing the dose. He notes that apple cider vinegar can help but doesn't actually build hydrochloric acid. The underlying cause of low acid may be a deficiency in potassium, sodium, or chlorides, which are needed to produce HCl.

Berg describes the gallbladder's role in storing and concentrating bile. He notes that the most common cause of right rib cage pain is not gallstones but bile sludge—thickened bile that clogs the ducts. He references older medical texts that used bile salts to dissolve gallstones and sludge. Taking purified ox bile or bile salts right after a meal increases the bile pool, enhancing fat digestion and flushing the ducts. He also mentions TUDCA as a specific bile salt for empty-stomach use to lubricate ducts. He personally suffered from this issue for a long time without knowing it, and the supplement brought relief.

Berg differentiates TUDCA from regular ox bile: TUDCA is taken on an empty stomach to specifically target bile duct lubrication and liver backup. He explains that when the bile duct gets jammed, bile backs up into the liver, causing referred pain to the right shoulder or mid-back. TUDCA helps drain the system, relieving that pressure. He recommends two capsules twice daily on an empty stomach. This protocol is particularly for those who have already tried ox bile with meals but still have upper back/shoulder pain, indicating a duct issue rather than just sludge.

Berg suggests intermittent fasting as a supportive strategy for SIBO. By extending the time without food, the body can focus on cleaning out the small intestine rather than constantly digesting. He pairs this with the carnivore diet to eliminate fiber, the primary food for bacteria. The combination starves the overgrowth and allows the MMC to function properly. He doesn't specify a particular fasting protocol but implies a daily eating window restriction.

Berg explains that for SIBO, no matter what you eat, it tends to feed the microbes. The carnivore diet is an elimination strategy that removes all plant matter, leaving only protein and fat, which are absorbed higher up and don't reach the bacteria. He recommends doing this for at least a few months, combined with intermittent fasting, to starve the overgrowth. He also mentions that some people do very well on no vegetables at all, and that the worse the digestion, the less fiber one can tolerate. After the SIBO is resolved, one can slowly reintroduce cooked or fermented vegetables.

Berg highlights L. reuteri as a 'key microbe that regulates a lot of other microbes' and states that most people are missing it, leading to SIBO. He describes a process of turning this microbe into a yogurt that contains hundreds of billions of microbes per half cup. Consuming half a cup daily can start to kill off the unwanted bacteria in the small intestine and reset the ecosystem. He references a video interview with a doctor on how to make this culture, indicating it's a specific protocol. This is presented as the 'ultimate correction' for SIBO.

Berg describes the ileocecal valve as a common site of pain that is often overlooked. In his practice, he would massage the area and teach patients to do it themselves, which often gave tremendous relief. He notes that this pain is usually a downstream consequence of problems higher up (low acid, bile, enzymes), so fixing the root cause is essential, but massage can provide immediate symptomatic relief. He suggests gentle pressure on the point to 'open things up.'

Berg addresses kidney stones as a possible cause of lower abdominal pain that can refer to the back or groin. He recommends an ultrasound over a CAT scan to avoid radiation. For prevention, he advises 1,200 mg of magnesium glycinate daily, explaining that magnesium connects with oxalates so calcium cannot, thereby reducing stone formation. He specifies magnesium glycinate for better absorption and tolerability.

Berg lists these four food categories as the ones to immediately avoid when correcting digestive issues. He explains that the worse the digestive system, the less fiber one can handle. Instead, he suggests cooked or fermented vegetables, which are easier to digest. This elimination is part of a broader strategy to reduce the burden on the digestive system while supporting it with supplements like betaine HCl and bile salts.

Berg walks through the entire digestive chain: stomach acid (pH 1-3) needed to denature proteins, activate enzymes, kill pathogens, and absorb minerals/B12; bile from the liver/gallbladder to emulsify fats; pancreatic enzymes for macronutrients; and the small intestine where 90% of digestion occurs. If any of these are deficient, undigested food reaches the large intestine or, worse, the small intestine (SIBO), where microbes ferment it, producing gas. He notes that as we age, stomach acid declines, and many people are put on antacids, which worsen the problem. The solution is to support these upstream mechanisms rather than avoid healthy foods.

Berg explains that the stomach needs a highly acidic environment (pH 1-3, comparable to battery acid) to properly digest protein, activate pepsin, kill microbes, and absorb minerals and B12. A sensor at the top of the stomach detects acid and signals the lower esophageal sphincter to close. When acid is insufficient, the valve remains open, and any acid present can reflux, causing heartburn and indigestion. This is why antacids, which further reduce acid, provide temporary relief but perpetuate the underlying problem. He notes that aging naturally reduces stomach acid, and many people develop digestive issues as a result. The fix is to add acid, not remove it.

Berg describes SIBO as a condition where microbes that belong in the large intestine colonize the small intestine, leading to fermentation in the wrong place. This causes constant bloating regardless of food, but especially with fiber and probiotics, which feed the misplaced bacteria. He explains that low stomach acid and low bile are key contributors because they normally kill microbes. Antibiotics can also trigger SIBO by wiping out beneficial bacteria, allowing yeast, candida, and fungus to overgrow, sometimes producing ammonia breath and skin issues. Undigested food stagnates, leading to severe constipation—he's seen patients who only had a bowel movement every two to three weeks. He personally suffered from SIBO for 15 years without knowing the cause. The solution involves starving the bacteria with a carnivore diet (no fiber) and intermittent fasting, then repopulating with L. reuteri yogurt to restore microbial balance.

Berg explains that the gallbladder stores and concentrates bile, a detergent-like substance that breaks down fats. When bile becomes too thick (sludge), it can clog the bile ducts, causing pain under the right rib cage and sometimes referring pain to the right shoulder or back. He notes that older medical texts used bile salts to dissolve gallstones and sludge. He personally experienced this problem for a long time without knowing it. The remedy is purified ox bile or bile salts taken right after meals to increase bile flow and digestion, and TUDCA (a specific bile salt) taken on an empty stomach to lubricate ducts and relieve backup into the liver. He emphasizes that many people have this and can correct it without surgery.

Berg argues that ultra-processed foods are already broken down, so they pass through the digestive system without requiring much work, causing little bloating. In contrast, healthy foods like raw vegetables, nuts, seeds, and beans are complex and require strong stomach acid, bile, and enzymes to break down. If any of these are deficient, the undigested material ferments, producing gas. This explains why some people bloat more after a salad than after a burger. He advises that while correcting digestion, one should avoid the hardest-to-digest foods (nuts, grains, seeds, beans) and opt for cooked or fermented vegetables, or even a temporary carnivore diet to give the system a break.

Berg uses the analogy of a fish tank: if the water is polluted, the fish get sick no matter how well you feed them or treat individual symptoms. Similarly, the body has 10 core signals—insulin, cortisol, inflammation, sleep quality, gut function, etc.—that all influence well-being. He asserts that in every person, one of these signals is more broken than the others, and until that specific signal is addressed, other interventions won't work. He created a free two-minute quiz to identify which signal is holding someone back, emphasizing that guessing leads to patching symptoms without resolution.
