Basic Guidelines – Bullet Proof Diet
Like most diets, the Bulletproof Diet has strict rules that you must follow if you want results.
It encourages certain foods while condemning others, recommends specific cooking methods and promotes its own branded products.
What to eat and avoid
In the diet plan, Asprey arranges food in a spectrum from “toxic” to “Bulletproof.” You’re meant to replace any toxic foods in your diet with Bulletproof ones.
Foods classified as toxic include the following in each food group:
- Beverages: Pasteurized milk, soy milk, packaged juice, soda and sports drinks

Cooking methods
Asprey claims that you have to cook foods properly to benefit from their nutrients. He labels the worst cooking methods “kryptonite” and the best “Bulletproof.”
Kryptonite cooking methods include:
- Deep-frying or microwaving
- Stir-fried
- Broiled or barbequed
Bulletproof cooking methods include:
- Raw or uncooked, slightly heated
- Baking at or below 320°F (160°C)
- Pressure cooking

Bulletproof coffee and supplements
Bulletproof Coffee is a staple of the diet. This beverage contains Bulletproof-brand coffee beans, MCT oil and grass-fed butter or ghee.
The diet recommends drinking Bulletproof Coffee instead of eating breakfast for suppressed hunger, long-lasting energy and mental clarity.
Along with the ingredients you need to make Bulletproof Coffee, Asprey sells several other products on his Bulletproof website, ranging from collagen protein to MCT-fortified water.
