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.

    Hi Zepp

    Thanks for your answer... but I don't think I explained myself properly. I'm eating a LCHF diet, with moderate protein. Assume for a particular meal, there's 100g of protein, only just a few grams of carbs, and 150g of fat.

    I totally understand how the carbs get broken down into glucose, maybe affects insulin slightly if they aren't stored in the liver or muscles as glycogen.

    I guess the proteins get broken down into amino acids and used.

    But what happens with the fat that I've eaten?


  2. Zepp
    Fat (triglycerides) is emulsified by bile in your duodendum and then broken down by ensymes to fatty acids and glycerol.

    Both are then transported through the gut wall and resembled again and put in chylomicrons and then transported by your lymphatic system and put in to the blood.

    There it is transported mostly to adipose tissuie and act on again by lipases stimulated by ASP and broken down to fatty acids and glycerol.

    Then adipose tissuie take glucose frome the blood and make glycerol of that and make a new triglyceride (triacylglycerole) for storage.

    The original glycerol backbone goes to the liver there it is converted to glucose.

    If you eat very litle carbs you dont get any insulin secretion.. its mostly high glucose levels that excret more insulin.

    Glucose is then managed by GLUT1.

    However.. amino acids always need insulin.

    Hello, I've been on LCHF diet for about 3 months. I feel good and don't miss carbs too much. The only problem I see so far is my cholesterol level results. It's very increased when before was always normal. What is your opinion on that? I would be greatful for your reply. Thanks!

    My age is 33.My results are:

    LDL: 324 mg/dl
    HDL: 100 mg/dl
    TRIGLICERIDE: 60 mg/dl
    TOTAL CHOLESTEROL: 324 mg/dl

  4. Zepp

    Its should be 6 or less, better if its 5 or less, perfect if its 4 or less!

    A HDL at 100 is very high and protective.

    Trg at 60 is very low.

    You cant have the same LDL as totchol.

    So I have calculated it for you.

    Its more probably that LDL is 197.

  5. martinkolo
    Thanks Zepp, my mistake:

    MY LDL WAS: 212 mg/dl

    What is that 3,24? What UNIT is it? mmol/l ?

    If so with my calculation: 324 mg/dl x 0.0259 = 8.3916 mmol/l AND THIS IS QUITE HIGH

    This is the calculator I used: http://www.soc-bdr.org/rds/authors/unit_tables_conversions_and_geneti...

    Yes its high.. but thats becuse your protective HDL is high!

    You dont need to convert anything, the qouta is there anyhow!

    TotChol dont say a thing.. for you it says that you eats more fat and there are more lipoproteins in your blood.. thats natural!

    However.. the best risk aproximation frome a standard lipid panel is the qouta of Totch/HDL=risk!

    Becuse if you got lower HDL and higer LDL, there is a increasing risk!

    But standard lipid panels is just estimations by measuring cholesterole content in different lipoproteins!

    Best estimations of future cardiovaskular diseases is best measured by APOb/APOa1 or by NMR!

    And then.. whats the fuss all about.. its about that if one got high levels of APOb, more of them can get stuck in your artery walls.

    And then again.. whats cause high levels of APOb?

    The most comon cause is hyperinsulinemi.. i.e. metabolic syndrome/diabetes.. another cause thats not comon is genetic dysfunction cald Famialiar Hypercholesterolemia!

    So the numbers of 6-4 is riskfactor for future CVD, there 6 is the upper limit there it increase and 4 is normal and healty!

    Heres an good explanation!

    I am hoping for some advice to help with resetting (my words) my metabolism. I have been on a LCHF weight loss program for nearly two years (March 9 will be 2 years). I have lost 80.5 lbs. I feel great. But, in the last probably 9 months I have not lost much at all, probably less than 10 pounds. In fact, I sometimes gain a few pounds, then struggle to get them off. I am very good with my eating habits. I consume probably 70 grams or less of carbs per day. I would say my average is probably about 50 grams. I eat a lot of cheese, meat, eggs, and heavy cream. I do not count calories. I eat only 3 meals, and sometimes in the evening if I want a snack it is typically peanuts in the shell, or sometimes cheese chunks or pepperoni. I walk 3 miles per day for the last 9 months which has changed since daylight savings time and the colder weather. I haven't been able to walk daily, maybe only 2-3 days per week. I've started doing weight resistance training and yoga as I can do this indoors. I have been reading a lot online about calorie cycling and/or calorie counting and also changing up the exercise as a way to jump start the metabolism. However, I wonder what others think of this? From Dr Eenfeldt's book I know he is not a fan? I do see a physician for my weight loss. He is an internal medicine, endocrinologist, and bariatric physician. He has suggested perhaps getting a treadmill so I can continue walking indoors, and also suggested resistance training. He impressed upon me the health benefits of already losing 80 lbs and the major improvements I've had in my labs, triglycerides now at 62, cholesterol 160, A1C 4.5. Fortunately, I wasn't diabetic and didn't have high cholesterol before, but at 295 lbs I knew I was headed that way. I still want to lose at least 30-40 lbs. Suggestions? Much appreciated. Lisa

    Have you seen glucose levels increase when vitamin k2 is started?
    Would this be expected as k2 reduces I sulking two hours after eating.
    My u derstandi g is the lower insulin is good and the increase in glucose not harmful.
    Thanks in advance eric

    I will report on my results after I have more data on some standard meals like eggs or dinner of salmon

    Usually my glucose is less than 84 unless I am sick or carbs aded two hours after meal like 8 eggs or 12 ounces of salmon

    I have been LCHF for about 7 months and have had success. Can you please give me a solution to the following problem. At this time I am experiencing symptoms only when I am curling.
    My heart rate is up and am breathing through my mouth.
    About 1.5 hours into the game, I experience dizziness and light-headedness. It doesn't happen every time.
    I have tried to find the answer myself, adding high salt broth prior to the game. Drinking extra water. High Fat Breakfast, High Protein Breakfast but haven't been a able to pinpoint the deficiency. A fellow curler suggested my glucose level may be low. If this is the case, can you suggest a solution.
  12. Paul
    Hi Lindsay, I'm not an expert, but if everything diet-related is in check (and it looks fine from my perspective), then there are two other scenarios to investigate: 1) low blood pressure, and 2) low oxygen uptake (you might be breathing too shallow).

    Just some thoughts... :-)

    All the best, Paul.

    Started off good. 1st week lost 6.5lbs. This week2 up 1. Not as active right now winter. Try to move though. I have 60 lbs to lose. Only thing I have off the diet is morning coffee w/ 1 1/2 tsps of raw sugar and little creamer. Count those carbs for the day. What can I do to get weight moving?
  14. Laura
    I am just about ready to give up. I have done LCHF for about two months. I cheated thrice during holidays I lost two pounds and around 1.5 inches around my belly. I followed the directions to eat as much as u want. I eat lots of fat. Have lowered my protein to try to adjust for no weight loss. I am often hungry but don't need to eat a lot feel full. Sometimes I think the hunger is mental. Other times it's denfinitley physical. I don't crave sugar or bread. I work out for the past month 1 to 3 times a week doing bork am yoga. I plan to increase that to at least three times a week. The past few days I tried tracking my food and am around 78% fat. 7% carb, 15% protein, 1400 calories. I use dairy. Cream in my coffee. Mozzerella cheese snacks. And sour cream and cream cheese some days. Ketostix shows 1.5 range.
    What am I doing wrong???
    I am female. 44 y/o. Typical insulin big belly. 176 pounds, 5 '0" and always been pretty muscular. I am really frustrated. I can't tell if I just angry I spent two months without little result and or experiencing that anger some peope talk about. Any advice?
