Myth busting & optimizing the ketogenic diet [interview]

Luis from KetoGains interviewed me about common myths surrounding the ketogenic diet and how to optimize a ketogenic diet for strength trainees. Here’s the full video interview.

    Great interview! I think the 1200 (I’ve heard 1400) kcal limit before things start going south goes back to Lyle Mcdonald.

  2. Seth says:

    Excellent points on salt, salt is the perfect, non-caloric, flavor enhancer. I relied heavily on salt to achieve a 50 kg weight loss. We’ve done a huge disservice by demonizing it.

  3. Rafael says:

    I “discovered” this site today and I’m impressed with the content so far. I would like to learn more about fitness and nutrition and this seems to be the place to find information. Is there a complete list of articles available anywhere on the site?

  4. Alex says:

    Great interview!

    Targeted Ketogenic diets with small carb window during lifting sessions have given me lots of results!

  5. Christian says:

    Another fascinating interview!

    I don’t eat any carbs, except perhaps a bit of fruit and veggies but I do consume lots of fat and protein and manage my workouts without tiring fine. I’m assuming I’m using my fat as my energy source as nature provided.

  6. Aziz says:

    Hi Menno,

    I just discovered this website today as well, and was wondering about this post and how you’re an advocate of a Ketogenic diet now.

    It seems the Ketogenic diet has been exposed as a fad that is not scientifically backed up or accurate.

    Please check these:

    Could you please share your answer to that information?

    Since you are a scientist, you’re always open to see contradicting research and analysis, and are willing to change your mind if have a higher probability of being accurate than the view you hold right now.

    Really looking forward to your response!

    • Hi Aziz,

      The ketogenic diet is a tool. The ketogenic metabolic state has costs and benefits compared to the non-ketogenic state, rendering it suitable for certain people, not for others. To say it is a ‘fad’ is just as silly as saying everyone should be using the ketogenic diet.

      • Aziz says:

        Hi Menno, I hope you’re doing well and I do wish you a great holiday period!

        You said that the ketogenic diet is a tool.

        Well, if someone is feeling better and thinking clearer on the ketogenic diet, do you think it’s not good for them to live in a ketogeneic state “forever”?

        Because the word “tool” can imply that it’s something temporary to get to a specific goal then stopped.

  7. Aziz says:

    Because of you, Menno, I started going Keto and it’s pretty awesome so far. I have much better alertness and focus, and I see results!

    I was wondering about something though: how fast does one drop off keto if eating some carbs?

    I’ll be visiting family in New Year, and in my case my mother will insist that I have some cake at midnight since it’s a family tradition to start the year with something sweet.

    So the question is: If I do take that piece of cake, does that put me back in square zero and I have to start again 3 weeks or more of keto adaptation to get back to the same state I am in now?

    Is 1 time enough to drop out of Keto? Otherwise, what is the threshold at which one just stops being in Keto?

    Thanks for being awesome, Menno, and for spreading the true knowledge not the Bro-Science stuff.

    • You’ll essentially immediately go out of ketosis, i.e. after a single meal, if you eat enough carbs. You can measure this with ketone blood/urine/breath monitors, which you should be using during a ketogenic diet.

  8. Hey Menno, I’m doing keto for brain health reasons. I’m a couple weeks in, so not fully adapted but I am starting to find the diet getting easier and carb cravings going down. Have lost a bunch of water weight and some fat, energy level’s been good, I’m sleeping well, gym performance is good, but the problem is my libido has completely tanked. I wake up with morning wood, but then have little or no libido on most days, and even when I do feel horny I get ED. Do you know why this happens or what I can do about it?

    • It could be related to your energy deficit or fat loss in general – or, more likely still perhaps, something else entirely (stress, psychological factors). I doubt it’s related to being in ketosis, especially considering you otherwise feel good and it’s not a common side-effect at all. You can try going out of ketosis though to see if it remedies the problem.

      • A carb-up did help, but I’m sure I was undereating. I wasn’t putting as much butter and coconut oil into my tea as I thought; I counted calories for a couple days and found out a tablespoon was bigger than I was picturing. I was probably eating a 1000 calorie deficit some days, without ever feeling hungry.

        Upping protein and fat intake, and moving on to the TKD, has helped a bit. Libido is still a bit on the low side though. So lack of carbs may be part of it too.

        Tomorrow I’m going to start a keto recomp cycle where I’ll follow the TKD with autoregulated carb-ups, I’ll see how that affects things.

        • Aziz says:

          But won’t those carb refills keep you out of ketosis forever?

          I have the same problem too. I’m in deep caloric deficit and don’t feel that hungry under ketosis.

          Still, my brain is loving ketosis.
