Dr. Jan Kwasniewski, Polish physician, developed his "Optimal Diet" in the 1970s. Extreme by any standard: 3:1 fat to protein ratio. Almost zero carbs. He called it "Optimal" because he'd tested it on thousands of patients. Results: - Obesity reversed - Type 2 diabetes resolved - Digestive diseases improved - Autoimmune conditions reduced - Energy dramatically increased His protocol was simple: "Eat fat. Lots of it. Minimal protein. No carbs." He recommended foods by fat content. Pork fat was ideal. Lean meat was inadequate. The Polish medical establishment called him dangerous. Heretical. "You can't tell people to eat mostly fat! They'll die!" Except his patients didn't die. They got healthier. He practiced for 40 years. Published books (in Polish, rarely translated). Treated over 50,000 patients. Documented their outcomes meticulously. Outside Poland, nobody knew about him until the 2000s when his work was translated. By then, low-fat had been the standard for 30 years. His extreme high-fat approach was considered pseudoscience. He died in 2004. His clinical success dismissed as "not evidence-based." 50,000 successfully treated patients apparently didn't count as evidence. He was right. We just weren't ready to hear it.
