Jimmy Moore and Eric Westman's new book, Keto Clarity, tells you virtually everything you ever wanted to know about ketogenic diets but were afraid to ask, and I would highly recommend it to clinicians and non-clinicians alike!

Keto Clarity by Jimmy Moore and Eric Westman

As a physician who personally follows a ketogenic diet, has studied the science behind it, and prescribed it for patients, I can attest that this book will be a valuable resource for clinicians and patients alike.  Anyone who is curious about the miraculous healing potential of ketogenic diets will love this book.  It is thorough, smart, and written in Moore’s signature style, using everyday language to explain complicated science without talking down to readers or insulting our intelligence.  He uses a simple Q&A format that includes helpful insights from experts and inspiring testimonials from people who have real life experience with the diet. All the big names in the world of ketogenic diets are here, including Dr. Ron Rosedale, a thought leader in the field, and Dr. Eric Westman, a leading ketogenic science researcher, and co-author of this authoritative book.

The book provides hands-on, practical information such as grocery lists and sample menus, as well as theoretical information for those who are interested in how the diet affects the chemistry of the body.  Moore busts silly myths about low-carb diets by using my favorite combination of weapons:  solid science plus (uncommonly) common sense.  I especially appreciate the way Moore separates fact from fiction from “we don’t know yet.”  In this respect, he is quite different from those nutrition specialists who are so personally and professionally invested in being right, that they have difficulty acknowledging the boundaries of our knowledge in the field and may overlook the fact that we are all unique and can vary in our response to dietary prescriptions.  This rare characteristic makes him a truly trustworthy source of high quality information about low-carbohydrate diets.

Bravo, and thank you, Mr. Moore and Dr. Westman, for this wonderful public service!

Inspired by Jimmy Moore’s new book, I wrote a couple of short companion articles to supplement the excellent information he and his associated experts provide.

The first article is about things to take into consideration before you embark on a ketogenic diet, particularly if you take medications for a chronic health problem or have certain health issues such as high blood pressure or anorexia.  “Is the Ketogenic Diet Safe for You?”  

The second article explains some simple ways to troubleshoot Ketosis and Constipation.

    Thank you for all this!

  • Thank you for bringing this book to my attention.

    Your Amazon hyperlink at the top of this post is broken. It is missing the colon, in the “http://” portion of the address.

      Hi Joshua,
      You are almost right. The link is actually to this site:
      http://www.http(dot)com ! I have no idea what that site is all about, and I’m
      afraid to find out. It sounds like a perfect address for a hacker! I
      agree with you wholeheartedly, the link should be fixed.

    • Thank you so much for letting me know, Joshua; I finally got around to fixing it and will be more diligent going forward!

  • Can you do this diet “halfway”?
    Also what was your original and current motivation to stay on a challenging diet like this?
    Thank you

      You cannot do ketogenic diet «halfway». There are different levels of ketosis though.
      But you can lower your carbohydrate intake gradually eliminating sugar and grains to begin with.
      To reach ketosis (mostly fat burning) you need to lower your carb intake to approx < 40 g. Usually 20-40 depending on the individual

    Dr. Edes,

    I am a new reader of your website who appreciates your measured approach to the hotly contested topic of nutrition and diet.

    In your post, you don’t use the present tense when describing your relationship with ketogenic diets “As a physician who has personally followed a ketogenic diet, studied the science behind it, and prescribed it for patients….” Am I to take this to mean you no longer follow the diet or prescribe it for patients? If not, please let us know what caused you to move away from it and what diet you follow now.

    Thanks, Callie

    • Hi Callie

      Right you are…I am currently not following a ketogenic diet. I first strayed from the diet when taking up a new full-time job at a new college, which made it challenging for me to continue to carefully track protein intake and plan meals carefully. I also found it challenging to sustain the diet for longer than about 6 mos due to my many food sensitivities, which exclude so many kinds of foods that most people who enjoy ketogenic diets rely on for variety and satisfaction, such as coconut, avocado, nuts, dairy, eggs, and most vegetables and spices. I fell back to my previous mostly-meat, very low carb, “Paleo”/whole foods diet sometime last spring. I suppose if I had a serious health problem such as a seizure disorder, bipolar disorder, or other brain illness, I might be motivated enough to return to it permanently, but given that I was primarily following it for weight/appetite control, as well as for scientific curiosity purposes, I’m not sure if I have the motivation to restrict my diet that much every day, but wonder if I might find it possible to use KD intermittently as needed for weight and appetite control.

    My Dr., who is referred to in Chapter 4 Dr. Gerber, recommended I read this book. I read it and am currently following the program, using the Precision Xtra as recommended. I have a followup visit scheduled, however I do have a quick question. Is a ketone level of .6 considered effective? Mine ketone ranges have varied from .6-1.3 being my highest. I have been testing for 10 days, twice a day.

    • I’d like to know this as well. That’s my ketosis range these first two weeks. I’m diabetic (type 1) so it’s a challenge to stay in ketosis, but I’m also wondering about the effectiveness of 0.6. Thanks.

    I have recently started a Ketogenic diet after reading Keto-Clarity. I am a 57 year old man who is very sedentary in the winter since my job is strictly a summer time job. After an initial 20 pound loss I have gained back 7 pounds. I have been measuring my level of ketosis with the Ketonix device and have been in a high level of ketosis the entire time. My diet has varied between 70 to 90% fat, 5 to 25% protein, and no more than 5% carb. I have not closely monitored my calories other than to not let them get above 2500. Since I weigh 365 currently I should be losing once I get below 4380 calories a day. My question is if a person is completely sedentary can that adjust downward the amount of calories per pound of body weight you need each day to maintain your weight from 12 to something lower like 8 or 9?

    • It seems your height would be a better measure of how many calories you need to consume each day, rather than your weight (unless you’re mostly muscle). Fat on the body doesn’t increase one’s metabolism so I wouldn’t think it should count toward figuring what your maintenance calorie intake should be. I’ve never heard of someone needing over 4000 calories a day unless they are majorly excercising. Sedentary usually means around 2000 cal/day, depending on individual BMR and height, etc. Not sure if this is the difficulty or not. The other thing I’d ask is whether the loss occurred in the summer and the gain in the winter? I’ve noticed that I lose without trying when I’m walking every day for work (happens rarely, so it stands out when I look back over the year) and then maintain or gain when I’m sedentary (and not trying anything) — these were the patterns before I started a ketogenic diet, but I won’t be surprised to see some of it still. Good luck!

    Hi Dr. Ede, I really appreciate your clarity to explain the benefits of following a right way of eating and making this priceless info available to everyone.

    I followed a strict ketogenic diet for 1.5 years with excellent results overall, but my hair started to fall pretty badly and I was told it was due to lack of insulin in the system. I took carbohydrates again and it subsided, bringing back the weight gain, uneasiness and other nasty disorders. I´d appreciate your thoughts on this.
    Also, I have not been diagnosed with arthritis, nor have I visibly inflamed joints, but I suffer from joint pain and rigidity mainly in the mornings. I found significant relief with the keto diet, but I still felt the pain in my hands. Maybe I haven´t seen it, but I did´t find any comments on arthritis in your site. Have you done any research on this matter?
    I am planning on following a keto/salicylate-free diet, since coconut milk and oil plus other vegetables might be causing the pain. Do you think that could be of any help?
    Thanks a lot in advance!

    • Hi Lorena

      It would be helpful to know if you changed anything else about your diet other than adding carbohydrates back in after going off of your ketogenic diet. People often eat very different foods on a ketogenic diet compared to a regular diet, and some of those foods can be problematic when it comes to general health and food sensitivity issues. Examples include foods high in histamine and other biogenic amines ( ), nuts, and coconut products. To the best of my knowledge, ketosis in and of itself, so long as you’re eating enough protein, fat, and calories, should not cause hair loss.

    IF Keto Clarity want you to eat fats liberally, it’s kind hard to do that when they have carbs… it important to count carb in the fats in order to get a lot more.

    • Davenna Carwie

      Oh lordy. Fats don’t contain carbs in general. There are things like avocado that are good fats however the fruit itself contains carbs, most of which are fiber. Fats and carbs are two separate micronutrients. Not all food with fat in contains carbs, for instance steak, chicken pork fat.
