Keto FAQ: Everything You Ever Wanted to Know About the Keto Diet


Eat fat to burn fat and lose weight. It sounds counter-intuitive, but this principle is the foundation of the ketogenic diet — a high-fat, low-carb eating style followed by celebrities like Halle Berry and elite athletes like LeBron James. Whether you’re thinking about starting keto or you’re five weeks in, here’s your guide to all things keto, including answers to common questions, and tips to get the best keto results.

Getting started on keto

1. What is the keto diet?

The keto diet is a high-fat, low-carb style of eating that puts your body into ketosis, a state in which you burn fat instead of carbs for energy. There are tons of benefits of keto, including weight loss, improved energy and focus, reduced inflammation.[1] [2] [3] To get the full story on what the keto diet is and how to get started, check out this essential.

2. How many carbs do I eat on keto?

In order to stay in ketosis and reap all the fat-burning benefits of the keto diet, you need to restrict your carb intake. The Bulletproof Diet recommends eating fewer than 50 grams of carbs per day, but all diets are different. Some keto diets advocate no more than 20 grams of carbs per day.

Because the Bulletproof Diet uses keto diet hacks like intermittent fasting and MCT oil to keep you in ketosis, you can generally eat more carbs than you would on a standard keto diet. But keep in mind that this number can vary based on your biology, activity level, age, goals and gender.

3. What foods should I eat on the keto diet?

For the best results on keto, stick to these principles:

  • An abundance of high-quality fats, like grass-fed butter and ghee, MCT oil, avocado oil, and virgin coconut oil
  • Moderate amounts of fatty proteins, like grass-fed meat, pastured eggs, wild-caught fatty fish, and collagen protein.
  • Lots of nutrient-dense and low-carb vegetables, like organic broccoli, zucchini, avocado, cucumbers, cabbage, and celery.
