My thoughts on Exogenous Ketones

Exogenous ketones? Beat the keto flu with Perfect Keto! #keto #lowcarb #highfat #theketodiet #ketoflu #exogenousketones #fatfueled #ketogenic #lchf

Should you supplement with exogenous ketones? What are the benefits? Which product is best? Are there people that shouldn’t use exogenous ketones?

There is so much health information out there that when you want to determine whether or not something is good for you it can be challenging to know what’s what. Magic pills, super supplements and promises to a better life are yours for three payments of two hundred dollars. I do not wish to add to the aggravation, which is why I never endorsed exogenous ketones.

Then, my mind was changed by many of you. Now, I can say that I’ve personally experimented with this ketogenic supplement and see that it can be helpful for some ketogenic people.

Not sure what exogenous ketones are? Basically, they’re a supplement that deepens your state of ketosis by providing supplemental ketones. They can be especially helpful for kicking keto flu and assisting your body in becoming adapted. If you decide to supplement with exogenous ketones, my personal choice is Perfect Keto exogenous ketones.

Why Perfect Keto? Well, to start, they are offering us an exclusive 15% off your first order of their exogenous ketones with the coupon code HEALTHFUL. So there’s something.


After personally trying Perfect Keto’s exogenous ketones, I see how they could be extremely useful for those dealing with things like: the keto flu, various conditions preventing certain people from going ketosis (fibromyalgia, thyroid, etc.), needing ketones for therapeutic purposes (for epilepsy, cancer, etc.), beginners on keto trying to get into ketosis for the first time, and those who need to extend a fast for medical reasons.

What exogenous ketones are NOT is an absolute fix-everything supplement because not everyone needs it, and if used improperly could lead to some serious drawbacks. For example, this should NOT be used to “erase” eating choices, in conjunction with excess carbohydrates or a carb up, to extend fasting beyond what your body is comfortable with, or to lose sight of why you started keto in the first place. Most importantly, this has the potential to be relied on too heavily, so keep that in mind if you decide you would like to try it out. But if it is used responsibly and purposefully, then it can be an awesome keto game-changer!


Should you decide to supplement with exogenous ketones, here are a couple other benefits to choosing Perfect Keto over other brands:

  • Contains 100% completely real ingredients. No fake stuff.
  • Free from soy, dairy, gluten, and artificial sweeteners.
  • No filler ingredients like inulin and xanthan gum.
  • Has 0g carbs per serving; other exogenous ketones have 3g.
  • Low price of $3.34 per serving (with today’s discount) as opposed to $6.50 from the other guys.


Now for the most common concerns people have. Many people, myself included, have had some serious concerns regarding exogenous ketones. For a long time, I wasn’t a fan. But that was before I saw how many people were benefitting from taking them, and before I came across Perfect Keto exogenous ketones.

If you have exogenous ketone supplementation concerns, I bet you can find your answer here:


I really like it when companies stand behind their product so I was thrilled to hear that Perfect keto stands behind their product with a 100% guarantee.

I want you to also be able to try it out to see if it can help you get over that keto flu and get keto adapted faster, so take advantage of their 15% discount for your first order (coupon code HEALTHFUL) and a guaranteed 100% refund of the price if you don’t absolutely love it. This is your chance to see what ketones do for you, completely risk-free.


I’ve chatted with the CEO of Perfect Keto, Dr. Anthony Gustin on the podcast twice – check out the episodes below for more information!

This might just be the game-changer you have been waiting for! Try it out for yourself!

  1. Any recommendations for a product actually available in Canada?

  2. I’ve only started recently started keto (will begin following one of your 30 day plans next week!) and just placed my order of the chocolate sea salt Perfect Keto. I was unsure about exo. ketones considering the steep price tag, so thank you for the discount code! So I’ll consider this my reward for all of the lunches out I have skipped in lieu of home cooked meals within the past few weeks. Thank you for all you do!

    • Glad this could help get you started with them!

  3. Hi Leanne!! I just wanted to let you know how much I am enjoying your podcasts. You walk with me every day, motivating me and giving me food for thought. I can still remember your second podcast where I discovered you live in Calgary and I freaked!!!! Who knew you live in the same province!!! That was kinda fun for me, (but not sure why. lol)
    I love your book (bought it at Costco) and all the information you share. What I love best about you is you have given me permission to experience food in a whole new way and how freeing eating has become for me. I no longer experience shame when I eat something that would normally make me feel bad about myself. After 55 years of beating myself up, this is HUGE!!!!! So, thank you for that.
    I just ordered some items from Pure Keto and hope that will get me in your facebook group so I can surround myself with people who share the same concerns and are on a similar journey. I left a different Keto FB group because I felt like such a failure.
    So, even though you probably hear a gratitude from many, I just wanted to share MY thanks to you. THANK YOU!!!!
    Happy Sunday and Keto on!!!

    • I am so happy to know you’re enjoying my podcasts so much! Congrats on finding food freedom– that’s definitely a huge accomplishment. I’m excited for you to try Perfect Keto, however, purchasing Perfect Keto isn’t a requirement for access to my secret Facebook group.
      Do you have The Keto Beginning, Fat Fueled, or The Keto Holiday Cookbook? These are the items that will give you access to my secret Facebook Group. Thank you for listening to the podcast and for all of your support <3

  4. Hi Leanne,
    I like to intermittent fast from dinner until mid afternoon, but I can’t kick my morning coffee (and the cream and sugar that goes into it, 2 cream 1 sugar). What is the ‘sweetness’ and texture of the base and MCT powder in coffee? I hate black coffee, but want to prolong my fast period with the brain boost of the ketones and MCT if possible.
    Thanks for all your great posts!

    • The exogenous ketones are very very sweet, but some people love it in their coffee. The pure MTC powder has no sweetness to it. There’s no noticeable change in texture after adding it to your coffee. Have you tried alcohol-free stevia for a bit of sweetness?

  5. I thought that ketones were produced by your body burning fat ? If that’s the case then wouldn’t it be pointless to take exogenous ketones.

    • If you’re already in ketosis, then you probably don’t need these. However, they can be helpful for kicking keto flu and assisting your body in becoming adapted. Here’s a post that explains all about exogenous ketones and how they work, if you’re interested.

  6. Want to try the Perfect Keto, but don’t know which one to buy. I’ve been following your book and recipes for about 4 months and I’ve lost 24 lbs. LOVE IT!!! I would like to “deepen my Keto sus state” (if I’m saying that correctly) lol
    So…which one should I buy? Where should I start?

    • I’m so glad you’re loving it! If you’re wanting exogenous ketones, they have two options: peaches and cream or chocolate sea salt. It all depends on which flavor you prefer! ;)

  7. FYI: If you go to the regular order page and choose what you want, then type in “Healthful” for the discount code, it will apply it to the entire order rather then clicking on the link above which only allows you to order one. I basically saved my shipping fees cause I’m in Canada. I got one of each flavor and the collagen. Hope this helps :) Hope it’s worth it cause those darn U.S funds are painful ;)

  8. Do you have an opinion on Pruvit exogenous ketones? (the product, not the business)

  9. Thank you for keeping us informed and educated on our journey into a keto lifestyle. Although this diet is new to me I believe I am already fat adapted, and I am playing with the different approaches suggested in your book. My question is: will the bad breath go away? My husband brought it up the other day and I was mortified! Since than I’ve been stuffing my mouth with xylitol gum all the time, which I am not a fan of doing.

    Is there anything that can be done to improve this horrible side effect?

    Thanks in advance and congratulations on the great work you do! :o)

    • You’re so welcome– thanks for following along! It should pass in a couple of weeks, it’s just your body trying to get the hang of using fat as fuel. If it continues, you can check out Fat Fueled for tips on managing it and getting rid of it.
