I Stopped Eating for 16 Hours! Look What Happened to My Health! Intermittent Fasting! Hubert Czer...

Czerniak stresses that the common advice to eat every 4 hours on a high-carb diet creates a ‘slave to the system.’ Shifting to a low-carb diet first eliminates the constant hunger and allows a natural transition to a shorter eating window. He advises ending the eating window by 18:00, then taking sodium bicarbonate two hours later and checking urine pH in the morning to ensure the body is not overly acidic. For diabetics, he claims that on keto, people can have glucose as low as 20 mg/dL without symptoms because ketones supply the brain. The protocol is presented as a gateway to a keto diet and eventually OMAD.

Czerniak describes his own morning: if he feels like having coffee, he makes it bulletproof. He has already produced a full episode on bulletproof coffee. He highlights the option to add turmeric and black pepper (to improve curcumin absorption) or clarified butter (ghee). He contrasts the satiety of the fatty coffee with the immediate hunger created by a carbohydrate breakfast, framing it as a tool to make fasting effortless.

Czerniak explains that when you finish eating at 18:00, taking bicarbonate two hours later helps counteract the acid load, particularly if the diet still contains excess protein. He instructs to check urine pH upon waking: a reading of 5.0–5.5 signals acidosis, meaning you're eating too many carbs or too much protein. By adjusting the macronutrient balance toward higher fat and moderate protein, pH should rise to the neutral/alkaline range, indicating better metabolic state.

Czerniak describes his precise morning sequence: Lugol's in a bit of yogurt or sour cream (for fat-aided absorption), then methylene blue in water (błękit metylenowy), and Mumio shilajit. He does this before coffee, about half an hour earlier, highlighting that these substances do not break the fast because they provide negligible energy. This suite is presented as his daily routine that supports high energy and cognitive clarity while fasting.

Czerniak explains that overweight children who are always hungry are trapped in a cycle where their high-carb diet depletes chromium and vanadium, making insulin less effective and perpetuating hunger. He recommends measuring chromium and vanadium levels, supplementing both, and adding vitamin B1. He references a dedicated episode on chromium for deeper dosage guidance. The underlying message is that these micronutrient deficiencies must be corrected alongside dietary change towards lower carbohydrate intake.

Czerniak draws a parallel to animals that instinctively stop eating when sick. He argues that the modern habit of pushing food on ill people is counterproductive and delays healing. He notes that the first sign of recovery is a returning appetite, at which point a nourishing broth is appropriate. This protocol is positioned as a natural extension of intermittent fasting, tapping into an ancient survival mechanism.

Czerniak describes his morning routine: he sometimes eats a little kefir or yogurt to take Lugol's iodine, then methylene blue in water, and after half an hour, bulletproof coffee if he feels like it, or just herbal infusions. He insists that herbs provide no energy (no glucose, protein, or sugar) so they can be consumed throughout the fasting period. His approach is built on the principle that once the body is fat-adapted, hunger signals diminish and the brain and muscles run efficiently on ketones. He positions this as an evolution from intermittent fasting to a 'warrior diet' — one meal a day — once the metabolism has been retrained.

He uses the example of animals that stop eating when ill and argues humans should do the same. Fasting eliminates the energy cost of digestion and mobilizes internal resources — through autophagy — to fight disease. He cites common illness like flu or tonsillitis: 'Nie jesteś głodny, nie zmuszaj się do jedzenia.' The return of hunger, he claims, is the first sign of recovery, and then a warm broth (rosół) can help restore health. This framing extends fasting from a weight-loss tool to a fundamental healing mechanism.

He cites scientific research showing that keto athletes perform similarly or better in sprint events. He tells the story of a supermarathon runner from Poznań who, during a race in the mountains of Chile/Argentina, brought a bar expecting a 2-hour energy cut-off but experienced no drop — he never needed it. Czerniak adds that as a teenager he played sports from morning until evening on an empty stomach, only eating a huge meal afterward, and maintained a lean weight. This suggests that a fat-adapted body can use stored energy efficiently for prolonged exertion.

He distinguishes apoptosis from necrosis. In apoptosis, the body scans for weak spots — cysts, fibroids, lipomas — and 'burns through' them, partitioning the cell into fragments. The weakest parts are consumed for energy, while viable organelles, even mitochondria, are reused in other cells. This process, he argues, is central to why ketosis helps with weight loss and chronic illness: it's not just fat but abnormal tissue that is catabolized. He ties this to improvements in type 1 diabetes, where fasting may reduce autoimmune attacks on the pancreas.

He explains that the insulin receptor requires chromium to function. When blood glucose drops, the chromium-insulin complex dissociates and chromium is excreted in urine. Children on high-carb diets lose chromium rapidly, creating a deficiency that impairs insulin sensitivity and perpetuates hunger. Vanadium deficiency often accompanies this. Czerniak recommends testing and supplementing chromium and vanadium, and adding vitamin B1 because high-carb diets deplete thiamine. He references a previous video on chromium for further details.
