“If you could bottle this up in a pill and let people take it… it would be the greatest selling drug in the world.”
— Jimmy Moore

Greetings, SuperFriends!

Today, we’re joined by Jimmy Moore, the blogger and author behind the Livin’ La Vida Low Carb Blog. Not only is the the author of about half a dozen books on ketogenic dieting… he also has an incredible story.

12 years ago, at 32 years of age, Jimmy weighed in at an alarming 410 pounds, and he knew something had to change.

In this episode, we’re going to learn how he dropped over 50% of his body weight, creating health and happiness in his own life, and inspiring tens of thousands of others to do the same.

I really enjoyed getting into some of the nitty-gritty details and science behind ketogenesis with Jimmy, and we throw out a lot of scientific terms you may or may not be familiar with. All in all, however, the conversation is really easy to follow, and whether you know about “keto” dieting or not, you’re going to learn a ton.

As always, please share your thoughts with me on Twitter @gosuperhuman, and if you haven’t already, please remember to leave us a review on iTunes or Stitcher.

Favorite Quotes from Jimmy Moore:

“Let’s see… when’s the last time I ate? 1, 2, 3, 4, 5… 7 Days ago is the last time I ate.”
“I don’t eat fruit. Fruit is nature’s candy.”
“We’re talking about eating to satiety so the hunger goes away.”
“The assertions… that fat is what’s causing insulin resistance and diabetes… There’s just no validity to that. There’s no science that supports that.”
“Nutrition science just frustrates the crap out of me!”
“If I got no other benefits out of a ketogenic diet but the brain health benefits, that’s what I’d do it for.”
“If you ballpark it, you may miss the park altogether.”
“It’s extremely hard to just fall into ketosis. You have to really work at it.”
“Too many people say ‘well how do I know if I’m in ketosis?’ Trust me… You will FEEL it!”
“I am currently in day #28 of a fast that I have been on. There have only been 3 days in those 28 that I have eaten.”

    How come you never asked Jimmy about his inability to maintain a steady weight? He lost 180 pounds in 2003 but since then has gained and lost well over 700 pounds!

    Look at this very recent photo

    Does he look like he’s at a healthy weight??

    Also – he admitted that the reason he went on his first fast in 2015 was to lower his lipid levels enough to scam the insurance company for a better rate on life insurance.

    Also – his wife Christina developed her auto immune disease while on the keto diet.

      An interesting point Charles. I’m not sure about it, but next time I talk to Jimmy I’ll mention it!

  • Tony

    I’ve listened to many episodes of Becoming Superhuman and most have been excellent and extremely thought provoking. This wasn’t one of those unfortunately. The guest made the comment that the reason why we should fast for for 5, 7, 10 days at a time is that our ancient ancestors would often go that many days between a successful hunt and so they were used to not eating for many days! That is paraphrasing as I don’t remember word for word what he said, but it was an absolutely ridiculous statement to make. Since when have homosapiens ever lived on meat alone? Between hunts they lived on vegetables, fruits, nuts etc. They didn’t starve until they managed to kill another animal. Sadly it wasn’t the only inaccurate comment made.
    The standard of guests on this podcast is usually impressively high, so if you are a newcomer to this podcast and this is one of the first episodes you hear, please don’t let the farcical comments made by Jimmy Moore deter you from listening to the usually excellent Becoming Superhuman podcast episodes.

      There is also NO evidence that being in a constant state of ketosis is in any way desirable. Unless you have cancer or epilepsy I see zero reason to be in it all of the time.

      Since Jimmy Moore is still not losing weight what’s next?

      • Jonathan Levi

        Fair points Charles. I hear ya. I will talk to Jimmy about this next time I we chat. I know that Jimmy has said in the past that his poor diet in the past has made it very difficult for him to maintain his weight (this is kind of a known effect of gaining weight – the body doesn’t get rid of the fat cells, just empties them), and he mentions in the post that because of his previous weight, he can’t even eat fruit. I think he said “I ate too many ho-ho’s and twinkies, my body can’t have fruit.” In any case, you make very valid points and I encourage the dialogue!

    • Jonathan Levi

      Thanks for the kind words about the show, Tony. I’m sorry to hear that you didn’t like this episode! Of course, not every episode is for everyone – this is the risk we take with such a wide variety.

    You really should do more research about your guests

    Again I ask – does he look healthy?? He can’t even fit on the machine.

    Jonathan – enjoying your podcasts – have you considered the fantastic Darryl Edwards (otherwise known as the fitness explorer) as a podcast guest? He certainly would meet the criteria of becoming a superhuman and would be a great addition to your show. His website is
