Study Notes

CrossFit Nutrition

  • CrossFit nutrition philosophy is contrarian and challenges the understanding of optimal nutrition.
  • Nutrition strategies are focused on avoiding disease and optimizing performance.
  • The CrossFit message emphasizes the importance of eating real food and avoiding processed foods.

Hyperinsulinism

  • Hyperinsulinism is the root cause of the "deadly quartet" (upper-body obesity, glucose intolerance, hypertriglyceridemia, hypertension).
  • Hyperinsulinism is caused by consuming too much carbohydrate.
  • Insulin is crucial for storing energy in cells and is produced by the pancreas.
  • Insulin resistance is caused by excessive exposure to insulin, making cells less responsive to its effects.

The French Paradox

  • The French paradox demonstrates how a high-fat diet, coupled with low sugar consumption, does not necessarily lead to heart disease.
  • Americans consume significantly higher amounts of sugar compared to the French.

Avoiding Coronary Heart Disease

  • Key principles for avoiding heart disease:
    • Eat a diet of meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar.
    • Consume foods that are fresh, whole, and unprocessed.
    • Minimize processed foods, sugary drinks, and refined carbohydrates.
  • Genetic predisposition to heart disease can be mitigated by dietary choices.

Optimizing Performance

  • Optimizing performance requires meticulous dietary tracking and controlling macronutrients.
  • Weighing and measuring food can enhance performance, as it fosters controlled intake of meat and vegetables, nuts and seeds, some fruit, little starch, and zero sugar.
  • The formula for calculating optimal nutrition is based on an individual’s lean body mass and activity level.
  • Leaning out too much can impair performance.
  • Adjusting fat intake can impact performance.
  • Increasing fat intake for individuals who are lean can potentially enhance performance.
