About Diet Doctor

AndreasEenfeldtMy name is Andreas Eenfeldt and I am a Swedish medical doctor specialized in family medicine. I want to find out how to get as healthy as possible using natural methods such as diet, exercise and perhaps a supplement (vitamin D) or two.

The idea to eat less fat and less saturated fat was certainly a mistake. Inadvertently that advice may be the biggest reason behind the epidemics of obesity and diabetes. More and more people realize this. It’s time for a health revolution.

This blog is a place to learn about this for free. Do you want real food, better health and weight loss without hunger?

LCHF for beginners


Read an interview with me from the Swedish LCHF-magazine, translated into English: page 1 / 2 / 3 / 4.

The Food Revolution

This talk by me summarizes the ongoing revolution. How we realize old mistakes and the most effective way to improve our health and weight.


Do you want to help change the world? There are many things you can do. Here are a few suggestions:

  • Be a positive example and inspire the people around you (answering their questions is more effective than trying to persuade someone who isn’t ready).
  • Learn more. These blogs are a good place to start, and there are some excellent books (1, 2, 3) on the subject.
  • Teach others: Comment on blogs and discussion forums and in papers, start a blog yourself, prepare a lecture, talk to your doctor.
  • Feel free to spread the link to dietdoctor.com and the talk on YouTube above. You may also use anything you find on this page in whatever way you like.
  • Do you have any other ideas? Please tell me in the comments below.

    Jänkarna kallar det family medicine, men britternas motsvarighet till allmänläkare är GP, general practitioner. Kanske ska skriva dit båda?

    Nitpick: Det är apostrofer (') och inte accenter (´) i "It's", liksom i andra fall där man ska via att bokstäver försvunnit (don't, can't etc) samt när man ska visa genitiv (the patient's health...)

  2. Simon,
    Thanks. I think it might be confusing to write both family medicine and GP.

    I have just spent a few hours with Monique Le Roux Forslund in Cape Town, a few family and friends got together to hear all about the LCHF way of eating, it is new to our country in fact we knew nothing about it all. Monique did a fantastic talk on this change of lifestyle and explained the entire concept very well, in fact I think she changed almost everybody's thoughts on how one should eat and more importantly WHY!!!! I will be changing my way of eating and preparing food as I am diabetic and have rheumatoid arthritis very badly and I feel that this will help me lead a healthier lifestyle... I really do wish that your book would be published in English in the near future....

    Hi Dear Doctot!

    I got information about you and your publication from one of my very close friend from sweeden. May be you know him. He is Mr. Kurt. He was spending a long vacation here in Sri Lanka and I was quiet lucky to have a chat with him and to listen to some expenations relevant to your Publication. Actually it is a very important area the whole world should know about. And its quiet apriciatable a person like you have taken the initiative. And I want to thank you for that.
    Further since my swedish friend like me to share this information with my other friends, I am hppily forwarding this to my 225 odd other friends. Bye.

    Take care.

  5. Duncan,
    Thanks! This site is still in its infancy, there will soon be a lot of more information here.

    Is the book pubished in english? were can i get it? I live in canada
  7. Anders,
    It's not yet published in English, only Swedish, Norwegian and Finnish.

    An English version may be on it's way though.

    I'd also be interested in reading your book, hope it's translated to English soon!

    What I find truly interesting in all this is that if I, a lay person who is 61, can recall a childhood and teen years (this would be the 1950's and 1960's) with very few obese people, surely others can as well. The question seems to be at what point did it all start to change, and what other factors changed around that time as well. In school, there were rarely more than a couple of overweight kids; most of us were skinny and lanky. There certainly were not the treats we now have available everywhere. I remember eating 3 meals a day, virtually no snacks unless it was an apple or something similar. My parents made cakes, pies and cookies as occasional treats. They didn't buy soft drinks, chips, cookies etc. and have them in the house at all times. I don't remember my friends' parents being overweight, either.

    I myself was perfectly slim until my mid 40's. I've always been mindful of diet and exercise, but at one point I did find myself at 174 lbs. (5'7") whereas most of life life I was a pretty steady 125 to 130. I believe this was due to increasingly eating too many sugary baked goods, which I am especially drawn to. I've never been a soda drinker, nor have I drunk much alcohol. I was never fat phobic, so low fat foods didn't play any role. I can only attribute my weight gain to sugar. It wasn't until I did LC diets that I lost most of the weight, and that furthered my beliefs about the role of sugar. However, I realize not everyone is the same in how they react to various foods.

    It's all a hugely fascinating subject, but too bad there isn't more agreement among the scientists. I'm continually astounded at how supposedly intelligent, educated scientists can completely reject the LCHF theories and the abundance of evidence about it.

    Hello Doctor,
    I am a 54 year old woman who recently started a job where there were mostly obese women. I have put on 28lbs since I started working with these women, I believe due to the manager having a wife who works in a cake shop and supplies us with cakes regularly. My mother says in "her day" we ate bread and dripping for tea, whats wrong with fat, we ate all meat with the fat attached, that's where the flavour is. I have done a low carb diet, with more protein, and it worked, I lost 25lbs on that diet, but true to form, started to eat the wrong foods again i.e. bread, rice, low fat etc, and it's all back on again. I always seemed to be hungry and ate all the time, grazing they call it, as if we were sheep. That's what we have become in this society though, just like sheep, we do what we are told, eat what we are told etc, and look what's happened to us. I have started to improve my diet, it's a process I know, you have to be strong to not have just a bit of this and a bit of that, cake, sweets and the like, which is what's in the kitchen when you live with somebody who likes that sugary stuff. I have improved though, eating only 3 square meals a day, using butter to cook with, and not oils, except for olive oil. I am enjoying my foods more than I ever have, even with the low carb diet I was on, as they did not include much fat, which I believe is the missing link. Fat is satisfying and makes me feel good when I eat it on a steak or on the pork roast, just thinking about it, yummy. This is for all who are sceptics, trying it for yourself, and eating as people have done for hundreds of years, is not going to kill you, and if you keep an eye on your cholesterol, get tested by your doctor now and after a few months to see just how your health is being impacted eating this way, well what do you have to lose except your chubby thighs and your big gut. I was slender all my life until I started to eat a "healthy" diet. I now know my weight, joint pain, short of breath, inability to sleep properly is due to my current weight. I do not smoke, drink wine occasionally and run around after my dogs and do housework and all the things that are good for me. Until now, I thought I would spend the rest of my life in pain and discomfort, and now I know there is a chance to reverse this damage and have a better life. Thank you doctor for helping people to see the simple truth.

    Andreas, you were so amazing at the Ancestral Health Symposium. Thank you so much! Can you direct me to anything in particular on your site regarding Type 1 Diabetes? Thanks! ~Amy
  11. Thanks Amy!

    Unfortunately I have not written anything about type 1 yet on this English blog. But an LCHF diet works beautifully to stabilize the blood sugar and reduce insulin requirements (a lot). Just be careful at first so that the person with type 1 does not get hypoglycemia from too high doses of insulin.

  12. Judie Ann
    I feel so privileged to meet Andreas Eenfeldt, MD today and will be starting my new eating on 13/8/11! What a great inspiration and intelligent man! I know I will be one of many success stories. :) Thank you so much Dr!
  13. Judie Ann,
    Thanks! Nice meeting you too and I look forward to following your story! :)

    Hi Andreas

    I read somewhere that you are a runner. I am assuming then that you have an interest in athletic performance.

    I was once a keen runner, until I got very fat. I am trying to remedy that, and hope to run again.

    A big question for me is: how does a relatively low carb diet affect athletic performance, whether low or high intensity?

    I understand some say that adaptation occurs on a lowcarb high fat (LCHF) diet and that performance is not affected. Phinney's studies are cited in this regard.

    Cordain and Friel obviously think there is an issue and advocate intake of readily digestible carbs (even potatoes I think ) in the post-exercise window. (Paleo Diet for Athletes).

    Colpo, a low carb adherent until a few years ago, advocates higher carb intakes in general (cf low car diets), but particularly just before, during, and after exercise, at least relatively high intensity and/or longer duration (e.g. .45 mins). (taking branched chain amino acids, liquid carb...eg dissolved glucose).

    Colpo in The Fat Loss Bible says that Phinney's work does not support the contention that there is adaptation on LCHF diets to the point that there is no effect on performance, and asserts that Phinney found that subjects on LCHF diets had their performance constrained at higher intensities.

    I would appreciate you thoughts on this when you have time - and I am sure a lot of your other readers would too.



  15. Funderaren
    Steve until Doc answers, read about this guy. He managed this on a LCHF diet.


    The next year, at his third Winter Olympics appearance, he won the gold medal in the pursuit event. He started the event in 8th place as determined by the previous sprint event, but managed to overtake the race leader on the final lap.

  16. Steve L
    Thanks Funderaren.

    I read the wikipedia article. My question: would this stand up to critical analysis: OK, he is on a LCHF diet, but what are the details? How much carb? And does he for example take extra carbs in during exercise and in the post-exercise window to replenish glycogen stores?

    I am not saying he couldn't have done this if he was strictly LCHF, but we need to have some scientific rigour in evaluating such cases.

    Thanks again for the link. I appreciate it.


  17. Funderaren
    I read that he eats 10-15% carbs. Not sure if he talks about energy % or amount %. Its low either way. You could say that because of his high energy intake he still gets plenty of carbs, but its alot less then the 60% he used to consume.

    His wife also eats LCHF, and she has won multiple world championships in armwrestling.


  18. Steve L
    Hi Funderaren....thanks for this. Interesting. Steve L
  19. Zepp
    The thing about Lowcarb and training is that you not need those high amount of carbs thats was the old paradigm.

    Its also clear that hunters did have a good performance on a diet on a low carb diet.. but elite endurace and paleolitic hunting is two different things, they probably have adapted some tactics to save there glykogen depoes.. and they should never run a maraton for fun.

    Its obvius that if you is an elit athlet then you do exercise thats need moore glucose then your body can make by its self.. elit exercise is not a natural behavior.. one can say!

    But if you are a ordinary person thats do som exercise for healt, then you probably dont need any extra carb loading.

    Here is that Phinney report!

    "Both observational and prospectively designed studies support the conclusion that submaximal endurance performance can be sustained despite the virtual exclusion of carbohydrate from the human diet. Clearly this result does not automatically follow the casual implementation of dietary carbohydrate restriction, however, as careful attention to time for keto-adaptation, mineral nutriture, and constraint of the daily protein dose is required. Contradictory results in the scientific literature can be explained by the lack of attention to these lessons learned (and for the most part now forgotten) by the cultures that traditionally lived by hunting. Therapeutic use of ketogenic diets should not require constraint of most forms of physical labor or recreational activity, with the one caveat that anaerobic (ie, weight lifting or sprint) performance is limited by the low muscle glycogen levels induced by a ketogenic diet, and this would strongly discourage its use under most conditions of competitive athletics."

    In Finland this book is well known and readers say this is 'the best book' to introduce LCHF. Everything has taken well and also it's very popular on libraries. I can honestly say everyone approves this book and opininion is you did really good job.

    Only critique I have seen is to your antioxidant part(s) of book. I am not very good in English and just a messenger. This is just a short forum post of Finnish antioxidant doctor, not from an article or anything. I try to refer. He also approves your book but only critique is this: you cited to meta-analysis which is not good, because they picked only 68 of 815 and they left out 'over 400-antioxidant-positive publications'.

    meta-analysis: http://jama.ama-assn.org/content/297/8/842.abstract
    He provided this as an answer:

    I just found this blog and I love how informative it is. My husband and I are on a path to getting healthy. We just discovered that he has very high blood pressure and is only 32 years old. He does not want to be on blood pressure medication at such a young age so we are looking for a natural approach to lowering his blood pressure. Anyway, we are cutting out the flour and sugar and have already seen the health benefits of that in just two short weeks. I am wondering what your thoughts are on Ezekiel Bread - it's a non-flour bread made with Sprouted Whole Grains? And I'm also wondering what your thoughts are on Organic Blue Agave Nectar?
  23. Funderaren

    Sprouted Whole grain is still full of carbs, and should be avoided. White flour bread is of course worse, but the other is not good. But its of course the lesser of two evils. So by replacing white bread with this should of course work better, but not as good as replacing the bread with lettuce or Oopsies.

    Agave nectar is terrible since its full of glucose and fructose. You could just use Coke bewerege instead. Its just as bad.

  24. Jules
    Bixby, a great blog to read is David Gillespie's "Raisin Hell" http://www.raisin-hell.com/

    which concentrates on fructose (DON'T touch the agave nectar!!!

    somewhere in his blog is stuff about blood pressure, and it's full of info that will keep you off the sweet stuff.


  25. Judie Ann

    Try to stay on the diet as much as possible with the information provided from the doctor, and stay away from any processed foods. Eat whole natural foods. That is what I have been following, and from my experience you will lose the taste for sweet things. I also understand that my cholesterol and BP will lower by staying on this regimen. I will find out in a day or so, my first month check up with the doctor is this week. :)

  26. June
    Just watched the Youtube lecture and it has really interested me but is it possible to follow a LCHF diet if I don't eat/drink dairy products?
  27. @ June Is it possible to follow a LCHF diet if I don't eat/drink dairy products? Yes the foods you will not be eating are Refined Flours, grains, sugars and foods with HFCS.
    You can find the foods Diet Doctor Recommends here http://www.dietdoctor.com/lchf'
    and you will see he tells people to " Be careful with regular milk and skim milk as it contains a lot of milk sugar. Avoid flavored, sugary and low fat products." Although Real butter, cream (40% fat), sour cream, fat cheese. Turkish yogurt. are recommended they are not a crucial part of the diet.
  28. Maggan A

    You should only choose what you know. WYSIWYG - What You See Is What You Get - is a good rule of thumb.

    That is; Eggs, meat, chicken, fish and other seafood, fat dairy like butter and full cream, and veggies that groes above ground. Then you are "home" and have nothing to worry about.

    Good luck to you and your husband! :-)

  29. June
    Thankyou Ted, I'm going to give it a try.
  30. Tineke
    Hi Dr Eenfeldt,

    I would like to add my request for an English translation! I am a New Zealander living in Sweden. My Swedish is good enough that I've been able to read your book, and I would love to be able to give it to all my family members in NZ.

    We have a lot of type-2 diabetics in my family, so I've always felt that I was pre-destined to become one of them. Now I'm looking forward to this never happening! Thank you!

  31. Tineke,
    Working on it! :)
  32. Rachel

    Just wanted to say I thought your talk was really well done and very informative. Do they teach you presenting skills at Swedish medical school? ;)

    I am really impressed that the health authorities in Sweden are taking low-carb eating seriously. I do wish we Brits would be more....well, Scandinavian about "new" ideas.

    Many thanks for this site and your talks.

  33. Carol
    Hi, I am new to this LCHF diet and just researching the benefits. I love my cup of tea with sugar (2 - 3 / day), can I replace the sugar with sweetner?
  34. Zepp
    Its up to you how hardcore you gonna be, but there is noting with sweteners that your body do needs.

    Some of them is posibly harmful.

    Maybe you can use it a time and then try to set it out?

    Do use stevia or Erytriol, those seems to be recognaced as safe food.

    I do drink coffe and tea whitout any sweet, its a habit thats everything should tast sweet!

  35. Rosemary
    I have a quick question for you, Dr.E. I am on day five of your LCHF eating plan. I am being pretty good about following the prescribed plan. I think I have just had a slight flare of gout in my right knee. (had a large flare 37 years ago shortly after my daughter was born and none since). I am hoping this is juat a coincidence and not attributable to LCHF. Could someone let me know if there could be any corelation, or of others have experienced such symptoms? Thanks. (I don/t want to use this as an excuse to come off the plan because your logic and science are very convincing)
  36. Alexandra
    @June if the reason you don't eat dairy is because of digestive problems, you may find, as I and many others have, that once the grains and sugars are gone, the dairy intolerance goes away too. I don't know why this is but I have read it over and over from other low carbers.

    Best of luck.

  37. Zepp

    Gout was before thougt to be associated whit purin rich food, like meat and seafood, its not.

    Its more associated whit genetics, alcohol, fructose and medical conditions.

    And LCHF is not a proteindiet, its a fat diet, one dont need to eat more meat than you need and want to.

    Its about to boost the fat oxidation, lower the glucose levels and get normal insulin.


  38. Lisa
    Hi Doc,

    Any idea when your book will hit Canada? I would love to read it.

  39. Sara Tavares
    Hello ;)

    Nice to meet you and thanks for your existence in my life.
    I start the diet one week ago.
    I am very pleased with the diet. It is not difficult.
    My breakfast at 7am is a Greek yogurt with 100 ml of milk fat, 6 berries, nuts and two 5 tablespoon of oats.
    At 10 am and 5pm i eat 3 tablespoons of ground almonds with 1 egg and 1 tablespoon of butter. Lunch and dinner I eat meat (chicken, rabbit, beef or pork) with broccoli, brussels sprouts and string beans with olive oil or mayonnaise and I finish with natural yogurt with some berries.
    Idrink 1 liter of water and 3 espressos a day.

    Delicious and very easy :)

  40. jusso
    I just watched your lecture tonight as it was recommended to me by my sister. I am going to try your LCHF starting tomorrow and have already cleared my pantry of all the evils it was holding :) however i do have one question...what about porridge? i ususally eat this every morning but I know this is a carb but it is not refined, so I am wondering whether i should continiue to eat this or not?
    thanks in advance, excited to get the ball rolling now :)
  41. Mike Ellwood
    Hello Andreas,

    I really enjoyed the video of your AHS talk.

    You have written elsewhere about the state of things in England.

    It occurred to me that you really ought to come over here and try to get on some TV and radio talk shows / discussion programmes.

    I think you would be really successful, and we need something!
    (The ladies especially would love you - And all things Scandinavian are popular here at the moment, what with Wallander, Stieg Larsson, and Forbrydelsen getting people interested in that part of the world).

    If you could persuade Gary to come over at the same time, and do a kind of double act, that would be even better!

    Please think about it :-)

  42. Bearhands
    Hi Dr Eenfeldt,

    Finding this site and your videos has been a revelation! I am definitely spreading the word in England, now that I know the 'truth'! ;o)

    I have a friend with Type 1 (insulin dependant) Diabetes (& heart disease), who is prescribed to regularly eat carbs and maintain a low fat diet and she was told that eating LCHF would be 'deadly' as she has disordered lipid metabolism.

    Is this true or would she benefit from LCHF? How does she get her Dr to listen and help her if so?

    Everyone just keeps pointing her to the British Heart Foundation advice - which is NOT LCHF!


  43. Deadly? Really? There is just so much ignorance still out there regarding low carb. Her lipids would likely improve with more of the good HDL cholesterol and lower triglycerides.

    Type 1 diabetics do great on LCHF, but she must be careful when starting as it will drop her insulin requirements and she will have to reduce her insulin doses a lot, possibly by about 30-60%. Taking too much insulin can of course be dangerous, as the blood sugar can drop very low.

  44. Bearhands
    Thank you Doc. I will pass on the message and I hope that attitudes in the UK can be changed eventually (although I fear that the 'fat phobia' is very set in here!)
  45. Dear Dr. Eenfeldt,

    I am going to start this way of eating today. I have been on The New Atkins for a New You, since August and have lost 30 pounds but I do not want to add back all the carbs. I like what you have learned and thank you for passing it along to us.

    I am curious about two veges that grow underground. Here in the States, we call them rutabagas and turnips. I use them to replace potatoes, some times with a roast or adding them to mashed cauliflower.

  46. moreporkplease
    "Here in the States, we call them rutabagas and turnips"

    Hi Arlene:

    So boiled mashed turnips have 8 total carbs per 100g (about 3.5 oz), or 5 net carbs if you subtract the fiber. Rutabagas are slightly higher carb: 9 total per 100g, and they have less fiber. So I might stick to the turnips and skip the rutabagas (what Brits call "swedes." :) )

    Like you, I'm basically sticking to what Atkins people would call OWL Rung 5, because what we know about beans (lectins, etc.) just doesn't make them worth the effort, imvho. Only by adopting this eating style did I discover that I was gluten sensitive! I always thought my headaches and fatigue were due to my women's issues. But with no grains, they've both vanished.

    I believe the only higher rung food I may add back will be the Japanese kabocha and red kuri winter squash. The red kuri squash has 7 total carbs, 6 net per 85g (about 2.5 oz), as does the kabocha.

    I'm sure you've been to a Japanese restaurant and seen that the Japanese eat these in very thin slices served as a tempura appetizer. These squashes are bright yellow, so they have a lot of great vitamins, obviously.

    A lot of people seem to be making tempura batter with coconut flour or flax & Parmesan, so LC tempura is definitely possible and might be a great way to add in more brightly colored seasonal veggies in a festive way.

  47. Hi Moreporkplease,
    I was a type II diabetic, not on meds yet, but getting there. My fasting glucose was climbing higher and higher. I went on Atkins and it was down to 84 the first week. I sure wish my doc had told me this so many years ago. He told me last week that I am not a diabetic anymore and I taught him some new things! He is going to recommend LCHF to all his type II patients now. DUH!!

    I know I will not be able to take my carbs higher than about 40 or so because that is where I will start having problems again. And I know that I can have treats once in a while and still come back to this way of eating so easily.

    I will eventually start cooking with coconut flour but just don't want to put all that in front of me to eat until I have reached my goal. Right now, I am very happy and look forward to experimenting more after the new year ad life is back to normal.

    So turnips will be more of a staple and rutabaga, a treat.... Yum..... and the winter squashes yet to come with butter and a good cut of beef. Double yum.

  48. Zepp

    The best book on lowcarb and type 1 is writhen in English.. Dr Bernstein Diabetes solution!


    Him self a type 1 seens youth!

    Think you can find a lot of advice there.

  49. Rebeka
    Hello Andreas, I love your blog. It was through my husband that I found out about it.
    We first saw the American documentary "Fat Head" and then my husband introduced me to your blog. We follow the LCHF diet for some time now. My husband lost 40kg, I was not obese, just gained some weight since I moved to the US from Europe so I lost 7kg. I love your lectures. I have a friend in Sweden who told me LCLF diet is so popular that at some point he could not find butter in the store.
    I just recommended your lectures and blog to my friend nurse in New Jersey just to be informed. All the best in your endevour to spread the right information about obesity and its causes. and Happy New Year.
  50. John Thorsell
    Hej Andreas!

    I'm really impressed with the work you are doing

    I would like to offer my help in translating your introduction to LCHF pge into Spanish.

    I am also a doctor born in Venezuela and half Swedish! (men jag kan inte pratar svenska då)
    I am opening a weight loss clinic in Australia, and would really like to begin correspondence with you for advice.

    Hope to hear from you soon.

    Have a happy and successful New Year.
