Study Notes

  • Success in health and fat loss comes from emulating healthy, fit individuals.
  • Finding a truly healthy population to model is difficult.
  • Outward appearances can be deceiving when measuring health.
  • Perfect physique does not guarantee optimal health.
  • Health is defined by the absence of disease signs and symptoms.

Weston A. Price's Research

  • Dr. Weston A. Price studied isolated traditional native populations in the 1930s.
  • He documented their diets and health, free from modern degenerative diseases.
  • These populations consumed traditional diets passed down for generations.
  • Dr. Price also studied native people who adopted refined foods.
  • He compared the health effects of traditional vs. modern diets.
  • Price's findings were documented in his book "Nutrition and Physical Degeneration".
  • Traditional natives had perfect teeth with no cavities, despite lack of dental care.

Physical Traits

  • Healthy natives possessed distinct physical features and facial structures.
  • Modernized natives exhibited higher rates of dental cavities and degenerative diseases.
  • Offspring of parents consuming refined foods were also negatively impacted.
  • Children developed narrow faces, crowded teeth, and higher tooth decay rates.
  • Diet impacts future generations, becoming a focus in epigenetics.
  • Lifestyle affects genes and offspring.
  • The effects of refined foods can manifest within a single generation

Diverse Traditional Diets

  • Traditional groups never counted calories or macronutrient ratios & ate real foods.
  • They remained connected to nature.
  • Diets varied based on location, climate, and food availability.
  • Foods were local, seasonal, grown in rich soils.
  • Animals consumed their intended diets.
  • The Inuit consumed an 80% fat diet of marine life and elk, with almost no carbs (not by choice).
  • The Massai of Africa ate a 60-70% fat diet of beef, raw milk, and cow's blood.
  • Swiss villagers ate dairy, rye, seasonal greens, and occasional meat.
  • The Kitavans of New Guinea consume a 70% carb and 20% fat diet of yams, greens, fish, and coconut.
  • Various healthy societies (Swiss, Kitavans, people of Laos/Cambodia/China/Vietnam) eat high carb diets.
  • There is no one-size-fits-all diet.
  • Focus should be on eating real food, not specific macronutrient ratios.

Saturated Fat and Heart Disease

  • Saturated fat and dietary cholesterol do not cause heart disease.
  • Massai tribesmen had low blood cholesterol despite high fat consumption.
  • The "diet-heart hypothesis" is deemed a scam driven by profit and prejudice.
  • Humans evolved eating fats and animals, especially in cold climates.
  • Heart disease is a relatively new phenomenon, while saturated fat is old.
  • Saturated fat in foods is not meant to harm us.
  • The French eat a diet rich in saturated fat and have low heart disease rates (the French paradox).

The Fear of Fat

  • People have been misguided by misinformation about saturated fat.
  • Coronary heart disease (CHD) was rare before the 1920s.
  • President Eisenhower's heart attack in 1955 brought heart disease to national attention.
  • Ancel Keys' Lipid Hypothesis linked saturated fat, cholesterol, and heart disease.
  • Keys' Six Countries Study supported his theory but was based on selective data.
  • The link between fat and heart disease disappeared when all twenty-two countries were included.
  • Associations do not imply causation.
  • Keys ignored human history and dietary trends.
  • Butter, lard, and animal fat consumption declined as CHD rose.
  • Vegetable oils, sugar, and trans fats increased during the same period.
  • Saturated fat was blamed for a modern health crisis despite declining consumption.
  • Keys' research led to him being on the cover of Time.
  • Saturated fat consumption has nothing to do with heart disease.
  • The link between blood cholesterol and CHD is debatable.
  • 50% of heart attack victims have "normal" cholesterol levels.
  • Eisenhower avoided butter and cream, replacing them with corn oil, but his cholesterol still rose.
  • Keys admitted there's no connection between food cholesterol and blood cholesterol

Overcoming Fear of Fat

  • Fear of saturated fat is based on false evidence and disregard for history.
  • Dietary recommendations worsened the heart disease/obesity epidemic.
  • It's unnecessary to adopt extreme diets like the Massai or Inuit.

Testing

  • If fearful of saturated fat/cholesterol, get lab work before changing your diet.
  • Retest after 6 weeks of dietary changes.
  • Tests should check for c-reactive protein, homocysteine, oxidized LDL, cholesterol particle size, triglycerides, LDL, and HDL.
  • The ratio of LDL to HDL is a better indicator of heart disease risk.
