Dr. Peter Attia on Very Low-Carb Performance

Dr. Peter AttiaDr. Peter Attia is a medical doctor, as well as a popular blogger and one of the founders of the Nutrition Science Initiative (NuSi).

Peter is an endurance athlete and has had a lifelong interest in health and nutrition.

Up until a few years ago, he used to believe in the old conventional wisdom of high-carb, low-fat eating in order to sustain peak athletic performance.

Over the years, despite massive amounts of exercise and eating a diet that was pretty much “perfect” by conventional standard, things started to go wrong.

He morphed from being lean to overweight and started developing symptoms of metabolic dysfunction: high triglycerides, low HDL, etc.

In the video below, Peter is interviewed by Dr. Andreas Eenfeldt.

He outlines the story of how he gradually transformed from a high-carb “conventional” diet to a low-carb, high-fat, moderate protein ketogenic diet, while drastically improving his health and his physical and mental performance.

  • On a low-carb, ketogenic diet, carbs need to be restricted, but consuming too much protein can also cause problems.
  • Excess protein can be turned into glucose and restricting protein may be necessary to get into nutritional ketosis.
  • Added sodium can alleviate many of the potential side effects (lightheadedness, physical performance, etc.) of a low-carb, ketogenic diet.
  • Individuals who are well keto-adapted often report improved brain function.
  • Athletes that are well adapted to ketosis can easily access stored body fat, which can lead to remarkable endurance performance.
  • Low-carb may not be as appropriate for athletes that function mostly anaerobically – sprinters, powerlifters, etc.
