The cyclical ketogenic diet, also known as carb cycling, involves alternating between periods of high-fat, low-carb ketogenic eating and higher-carb intake days.

The goal is to achieve ketosis, a metabolic state where the body burns fat for fuel instead of glucose. This variation is popular among athletes seeking muscle growth and exercise performance.

To get started, one should adhere to a standard ketogenic diet protocol for 5-6 days a week, followed by 1-2 days of higher carb consumption to replenish glucose reserves. On refeeding days, carb intake is increased to roughly 150 grams.

It is recommended to consume healthy fats and high-quality protein sources, while keeping daily carb intake between 20-50 grams.

The Bulletproof cyclical keto diet involves additional hacks like intermittent fasting, drinking Bulletproof Coffee, and adding Brain Octane Oil to meals to make it easier to achieve and maintain ketosis.
