Being Bulletproof is about asking questions and getting answers. Take that suspicious spot on your calf, for example. Have you ever wondered what the heck it is? Have you ever questioned how marijuana can have an effect on heart rate variability?

Each month, I record a special podcast to answer questions from the Bulletproof community. We pick the best questions that come from emails, Facebook, Twitter, the Bulletproof Forum, and the blog’s comment section. In this show you’ll gain access to a wealth of information that I hope will empower you on the way to living a more optimal life. Please enjoy!

    Hey can you post your blood work history dave? Inquiring minds want to know hard numbers, especially since you sell a product line and have a commercial brand.

  • Jesper

    Hey. So if one get slightly nauseous when drinking coffee with butter, it is probably because I haven’t fully learned to use fat for fuel? So I should be more strict about excluding carbs?
    I sleep enough, strength train 3x/week, bike around 60 km a week for transportation and I’m 22 years old.

    • Jesper

      By the way, is the “Better Baby Book” for everyone or mostly parents?

      • abright

        It is written for parents, but everyone, even non-parents benefit from it- having good fertility is correlated with being healthy.

    • You could just be drinking it too quickly. See if the nausea corresponds to mornings when you’re rushed. (This happens to me sometimes.)

    • abright

      You may also need to add a digestive enzyme, I like solary w/ oxbile.

      • Katherine

        So anytime I have too many carbs one day, am I shooting myself in the foot to feel nausea with bulletproof coffee the next?

  • Yoni

    http://www.bulletproofexec.com/upgraded-chef/ – where is there a downloadlink to the book?

  • tosha120

    I was wondering, The use of fat( butter/oil/fatty meats) Is this known to be unlimited for intake? and Do you think for someone who has like a lean body already and wants to drop maybe a few inches, would they need to limit their fat intake, or no? also is it better if the percentage of fat is on the higher end and the carbs on the lower end close to a 75-90% fat and less then 5% carbs and rest protein?

  • Binkster Tippings

    getting sick of hearing people copy Dave Asprey’s every voice inflection right down to those little throat/diaphragm noises he makes on air.

    • Peter Fitzwell

      wow. you need a hobby.

  • J

    Is there a video of this podcast?

  • cogrick2

  • Marijuana — even medical marijuana — is often very moldy. The an apparent negative impact of smoking marijuana on heart rate and heart rate variability sounds like possibly mycotoxins to me.
