SAMA HOOLE: 1845 Franklin Expedition: 129 men. Provisions: Canned lean meats, hardtack, minimal fat. Result: All dead within 3 years. Scurvy. Starvation. Despite adequate calories.

Arctic expeditions had to choose provisions carefully. Wrong choice = death.

Arctic expeditions had to choose provisions carefully. Wrong choice = death. 1845 Franklin Expedition: 129 men. Provisions: Canned lean meats, hardtack, minimal fat. Result: All dead within 3 years. Scurvy. Starvation. Despite adequate calories. 1903-1906 Roald Amundsen: Learned from Inuit. Provisions: Pemmican (50% fat), seal blubber, fatty meat. Result: All survived. Good health. Success. The difference: Fat content. Franklin's men had calories. They didn't have fat. They died.

Amundsen's men had fat. They thrived. Ernest Shackleton, Antarctic: Relied on seal and penguin (both high-fat).

Survived 2 years stranded. Zero scurvy despite no vegetables. Pattern is consistent: Expeditions that prioritised fat: Survived Expeditions that didn't: Dead Animal fat kept explorers alive in the harshest environments on Earth. But you're told to avoid it in your climate-controlled flat because it might raise your cholesterol. The explorers would think you're insane.

SAMA HOOLE: Mackarness argued: "The fattening substance is carbohydrate. Animal fat doesn't make you fat."

No sugar, no carbs, just meat, butter, and cream.  --Dr. Richard Mackarness

1958: British doctor Richard Mackarness publishes "Eat Fat and Grow Slim." The title alone was heretical. Everyone "knew" fat made you fat. Mackarness argued: "The fattening substance is carbohydrate. Animal fat doesn't make you fat." He cited thousands of his own patients who lost weight eating high-fat, low-carb diets. The book sold over a million copies. People tried it. It worked. For about 5 years, Mackarness was vindicated. His approach was mainstream in Britain. Then the American dietary guidelines came. The Seven Countries Study. The fat hypothesis. By the 1970s, "Eat Fat and Grow Slim" was considered dangerous pseudoscience. Mackarness was called a quack. His clinical results dismissed as anecdotal. He'd successfully treated thousands of obese patients. Documented their weight loss. Published the outcomes.

None of it mattered. The narrative had shifted. Fat was now the enemy. Carbs were fine. Mackarness spent the rest of his career fighting the new orthodoxy. Lost that fight. He died in 1996. His book is out of print. His work forgotten. He was right in 1958. We're still pretending he wasn't.
