To Ketone Endogenously or Exogenously?

That is the question. By now you've probably heard the term keto, ketosis, or are familiar with a low carb diet.

Exogenous ketones are gaining huge popularity in the health and wellness market. I want to take a minute and help you understand what they are and how they work. But first, what is ketosis? Ketosis is a naturally occurring metabolic process that happens when your body is absent of glucose and converts fat into ketones to use as fuel.  That sounds fantastic!  Who doesn't want to burn off excess body fat?  

Not so fast though. As easy as it sounds it takes some effort.  The main driver of ketosis is carbohydrate restriction.  Carbohydrates are the main food source for nearly everyone.  It's a tough transition away from them.  But with enough determination and a quality support group it can be done with great success.  I've helped many people lose a combined total of 3000 pounds and counting using a keto/low carb diet.   

Your new fuel is now fat.  Both stored body fat that comes in the form of ketones and dietary fat.  I know, that's life changing news. But it's still not an all you can eat fat buffet.  Some types are better than others.  That's where a health coach or nutrition advisor, along with guidance from your PCP comes in to help you make the most of your dietary change.  

So, why use exogenous ketones if you can produce them naturally?  Great question.  I asked several health and wellness professionals about the use of exogenous ketones and here are some of the responses I got.

  •  Here is the deal: Keto is currently on "hype" because a lot of MLM companies are pushing it hard.  
  • Exogenous ketones do have "a place": as a nootropic, to improve concentration, even cancer treatment and prevent or help with epileptic seizures.  Also, they can improve sports perfomance. 
  • Exogenous ketones DO NOT help with fast loss. They may even inhibit fat loss. 
  • Ketones are a by-product of fatty acid metabolization that your body can use as energy (well, only BHB, beta hydroxybutyrate,  as acetone and acetoacetate are waste products).  If you give your body exogenous BHB... it amps down lypolisis: why buy the cow when you can get the milk for free?  Remember the body utilizes macros in certain order: Alcohol (ethanol) > Carbohydrates (glucose) > Protein (Aminoacids) > Fat (Fatty Acids)
  • If you give your body the end product it will always use it first, as it requires less energy to process. The body wants to survive and conserve energy. 
  • The product does not "PUT YOU IN KETOSIS" - it introduces ketone bodies in your body. Different things. It is false ketosis in a way.

The only time I would ever see using exogenous ketones is if one was already following a ketogenic or low carb diet for several months and a found a need for them as described above (cancer treatment, seizures, nootropic, athletic performance etc). 

I found this article from a well respected ketogenic community.   It's worth checking out if you are interested in this product.   to-ketone-or-not-to-ketone.

Hopefully that helped!  I wouldn't want to see anyone drop a few hundred dollars or more on a weight loss supplement with no real guidance on how to make the most of it or knowledge of what it actually does. And remember, these products are sold as a SUPPLEMENT.  That means in addition to.
