I recently bought the Bulletproof Diet book by Dave Asprey. I kept hearing about bulletproof coffee (coffee with butter and either MCT oil or coconut oil added) all over the web. In the end, I thought coffee with butter in it couldn’t be all bad. Finally, I was intrigued enough to buy the book in kindle form.

Although I’m calling this a review it is rather more a collection of notes that I have written as I read the book. These notes will act as reminders of the core messages of the book.

Foreword by JJ Virgin

Describes how Dave (Asprey) has biohacked his way to mental clarity and physical fitness, losing over 100 pounds.


Dave weighed 300 pounds despite working out 90 minutes 6 times per week and living on 1,800 calories per day.

Diagnosed with thrombin induced platelet aggregation

Sick all the time with sore throats and sinus infections.

Bad brain fog, a scan revealed little activity in the pre-frontal cortex.

These experiences led Dave to try to bio hack his way back to full health.

He tried the following

  • “smart” drugs
  • supplements
  • different diets
  • spiritual practices
  • bio feedback
  • home EEG monitoring

From these hacks he discovered

  • how diet impacted his bodies thinking and biology
  • roles of toxins, hormones, gut bacteria in weight loss hunger and energy levels

As a result, Dave lost 100 pounds and maintained. His friends and family also lost weight and saw health improvements.

Chapter 1

Dave wanted to understand why do we wake up feeling different from day to day.

  • For example, puffy face or muscle weakness
  • waist size changes
  • brain fog

Dave came to the conclusion that these were all caused by inflammation. The inflammation caused by a standard American diet that irritates the gut which in turn triggers the immune system.

Chapter 6 – Working Out

Dave found out that working out for 90 minutes 6 days per week did not reduce his weight. Strength improved, however, he realized that he was over training (a very common problem).

Most of your bodies appearance is down to what you eat.

Interesting definition of exercise by Doug McGuff MD “Exercise is a specific activity that stimulates a positive physiological adaptation that serves to enhance fitness and health”

Dave recommends weight lighting 15 minutes no more than 3 times a week.

Don’t do extended cardio workouts instead follow a HIIT High-Intensityy Interval Training) protocol instead.

Recovery after exercise is very important, you may need more sleep to recover.

Chapter 7 Multivitamins and Supplements

The American standard diet is low in nutrients and micro-nutrient deficiency is common.

Deficiencies can cause problems with fatigue and poor sleep.

General multivitamin supplements are not recommended as you can overdose on some vitamins or minerals while being under-dosed on others. Best to take supplements individually.

Generally, with supplements, you get what you pay for. Cheaper supplements can be made up of cheap fillers and cheaper forms of the vitamin or mineral you require.

There is an up to date list of the top 10 supplements Dave Asprey recommends here.

Need to look at supplementing with the following

Vitamin d


Vitamin K2

Vitamin C


EPA and DHA unless you are eating plenty of wild caught fish.

Vitamin A unless you are eating plenty of grass fed organ meats.



Vitamin B12 and Folate

Chapter 8 – Why the Bulletproof Diet works for Men and Women

Men and women have different hormone levels and different bodies.

Women may need to tweak the diet to give better results. Intermittent fasting could be a problem for some woman.

A high fat low carb diet could boost fertility and sustain a pregnancy.

Plenty of healthy fats and a low carb diet improve hormone levels, suppresses bad gut bacteria and promote weight loss.

Women should add

  • sea salt
  • eat protein with breakfast but not carbs.
  • re-feed cards at least once a week (men can go longer) this is done once a week during protein fasting days. Eat sweet potatoes, carrots and white rice on these days.
  • drink de-caf coffee if pregnant.
  • get tested for iron levels after 2 weeks on the diet. Take supplements only after testing has shown you are deficient.

Men should start the bulletproof diet 3 months before trying ti conceive.

Sex Hormone Supplements for Men and Women

Zinc – deficiency can lead to lower testosterone levels (important for women too)

L-ornithine and L-Argnine – these amino acids stimulate the release of human growth hormone.

Orally available glutathione in a lipid preparation.

Activated coconut charcoal – great for detoxing as it binds to toxins and takes them out of your system.

Testosterone – needs to be made by the body. High blood sugar levels reduces testosterone levels. (Cornflakes and graham crackers originally designed to reduce libido).

The bulletproof diet that is high fat and low carbohydrate naturally increases testosterone.

Feeding kids

– children do well on a high fat low sugar gluten free diet. Kids need more carbohydrates than adults.

Dave Aspreys children were brought up on the bulletproof diet, they have turned out well behaved and able to concentrate well.
