206. James DiNicolantonio: supplementation and nutrient deficiencies, eggs vs. bagels for weight loss, creatine and diet

Paul Saladino MD Podcast with James DiNicolantonio 2023-03-14

Summary

Paul Saladino and pharmacist/author James DiNicolantonio cover creatine and carbs for post-exercise recovery, their views on fasting and keto, insulin resistance, magnesium supplementation, and hydration optimization. They discuss how targeted supplementation can complement an animal-based diet for optimal health.

Key Points

  • Creatine for post-exercise recovery and cognitive function
  • Carb timing around exercise for performance
  • Fasting and keto: benefits and concerns
  • Magnesium and hydration optimization strategies
  • Insulin resistance mechanisms and dietary approaches

Key Moments

Creatine

Take creatine post-workout with carbs for 7x more storage

Creatine phosphate storage increases sevenfold when taken around exercise versus at rest, and another 50-60% when combined with carbohydrates.

"There's a sevenfold difference in how much creatine phosphate gets stored if you take creatine around the time of exercise versus not."
Magnesium

Magnesium, thiamine, and vitamin C deficiency cause insulin resistance

Clinical deficiency studies show that low magnesium, thiamine, or vitamin C can each independently induce insulin resistance in humans.

"Any nutrient deficiency, particularly a deficiency in magnesium, a deficiency in thiamine, this has been proven in clinical studies in humans to induce insulin resistance."
Magnesium

50% of the US population may be magnesium deficient

DiNicolantonio estimates about 50% of Americans are magnesium deficient. Even marginal deficiency increases arrhythmia risk.

"If you bring the magnesium intake down to 100, 110 milligrams, one out of three people develop atrial fibrillation."
