Cancer, Glycation, Essentiality, Oxidative Stress: Carbs Are Not The Cause

Carbohydrate restriction forces the body into physiological insulin resistance — a survival-mode conservation mechanism that suppresses metabolic rate, elevates stress hormones, and downregulates thyroid and reproductive hormones.

Key takeaways

Glycation intermediates are 20,000x more damaging than glucose itself

Glycation intermediates are 20,000x more damaging than glucose itself

  • Dicarbonyl compounds (from incomplete fuel metabolism) are 20,000x more glycating than glucose — the fuel type is irrelevant.
  • Ketones, amino acids, and fatty acids all produce these same glycating intermediates; this is a metabolic efficiency problem, not a sugar problem.

Carbs produce more ATP per ROS than fat — making them more metabolically

Carbs produce more ATP per ROS than fat — making them more metabolically

  • Fat oxidation generates significantly more reactive oxygen species per ATP produced, slowing the electron transport chain and citric acid cycle.
  • Higher ROS acts as a natural brake on ATP production via uncoupling; carbohydrate oxidation avoids this bottleneck.

Low-carb diets trigger stress hormones that suppress thyroid and sex hormones

Low-carb diets trigger stress hormones that suppress thyroid and sex hormones

  • Carbohydrate scarcity signals famine; the body upregulates cortisol and downregulates thyroid and reproductive hormones as a survival adaptation.
  • Same mechanism applies to very low fat intake — both macronutrient deficits carry hormonal costs even if survival is maintained.

Ep 4: Blood Sugar Part 1: Blood Sugar Regulation and Energy Balance

Eat carbohydrates every 2-4 hours with protein at a 2:1 carb-to-protein ratio to prevent blood sugar drops that trigger stress hormones like cortisol and adrenaline.

EB. 11: Weight Loss Part 2: The True Cause of Weight Gain

Weight gain occurs when cells cannot efficiently convert food to energy, forcing storage as fat rather than fuel utilization — the solution is removing metabolic blockers like endotoxin and polyunsaturated fats while ensuring adequate nutrients, not eating less.

EB. 1: Energy is Everything

Focus on creating an energy surplus by improving cellular energy production rather than following calories in/calories out—this means eating enough fuel (food) while removing factors that block the conversion of fuel to usable cellular energy.

The Fat-Burning MYTH: What the Research Actually Shows

Optimize mitochondrial function and reduce chronic stress hormones rather than forcing lipolysis through fasting, cold exposure, or ketogenic diets — HSL-knockout mice had 3x less body fat despite severely blunted fat release, and overweight men on a ketogenic diet lost the same 0.5 kg of body fat in 28 days as they did in just 15 days on a high-carb diet.
