Exe-what?? That is what I said when I first heard the term exogenous ketones. Had it not been from someone I trusted (the almighty Tim Ferriss, who you can find here) I probably would have thought it was something made up and overlooked it. However, when Tim says try something, I have learned to try it – with some exceptions, of course – and now it makes my list of top hacks.
Exogenous ketones are BHB (beta-hydroxybutyrate) salts. Ketones are produced naturally and used for energy by your body when fasting or when carbohydrates are restricted. They are referred to as energy on demand, and in my experience, that is exactly what occurs. Ketones are easily accessible to the brain, more so than glucose, so when in a state of ketosis or taking ketones, the brain also has a ready supply of fuel. This adds to clarity and focus, and often enhances mood as well.
Exogenous ketones are essentially packaged ketones that are ready for you to take when needed. Common uses are before a workout, to extend a fast, to provide instant energy and focus if you are in an afternoon slump, to get back into ketosis after consuming sugar, or added to your morning coffee.
There are powders, liquids, bars, drinks, creamers…whatever tickles your fancy, there is a way to get your ketones. I started with a liquid that tasted like sea water and looked like…well,I probably should not say what it looked like but let’s just say it was not my favorite presentation. I tried disguising the taste in all sorts of concoctions and finally decided to just down it. The result was worth a moment of sea water and besides, who hasn’t drank sea water on multiple occasions without getting the energy and focus afterward. I tried a few different types of powders, coffees and creams after that and finally settled on my favorite, Keto/OS from Pruvit. It is combined with powdered MCTs and the jolt of energy, mood enhancement and focused mind that I get is worth dealing with its odd taste. (You stop noticing the weird taste after a while, I promise.) I have the caffeinated version for mornings, the non-caffeinated version for any other time of the day, and the Kreme for midday hot cocoa (Keto Hot Cocoa – half a mug of water, half heavy cream, a heaping scoop of cacao, and a packet of Kreme. Tasty and good for you too!).
When I am asked about ketones by someone for the first time, I often recommend KetoForce’s Keto Sports liquid, which you can find by clicking this link. It is a good entry into what exogenous ketones can do for you without some of the interesting side effects of the more powerful ones (also known as disaster pants – see the Bulletproof blog here for an explanation of that.) It is what I started on as well.
If you are ready to go straight to the top (in my opinion, at least) you can find Keto/OS or other Pruvit products through my affiliate link here or by going to their website.
I am not joking when I say this is energy on demand. I wish I had known about this when my daughter was little, and wish more people knew about it now. We don’t have to be tired all the time, we just need exogenous ketones!
Let me know if you have questions, and if you have tried them, what your experience has been with exogenous ketones.
