“What about cholesterol?”


What about cholesterol, isn’t it going to balloon up? What are your thoughts on red meat and dairy? What do I do if I can’t consume fat anymore?

Get the answers in this week’s Q&A with Dr. Andreas Eenfeldt:

What about cholesterol?

When I told my wife i was starting this diet and she say all the fat and butter, she asked “What’s going to happen to your cholesterol? Isn’t it going to balloon up?” I don’t have an answer for her.


For most people not much happens, except for an improved cholesterol profile (more of the “good” HDL cholesterol, and lower triglycerides (a good thing too). For a smaller minority, LDL and total cholesterol may rise significantly, but even then the good changes are seen too.

Red meat and dairy!

Watching documentary film ’What The Health’ on why we shouldn’t eat meat and dairy!

What are your thoughts on this?

How to get full when I can no longer consume fat?

Been LCHF for over a year and a half. For the last 3-4 months, my body has gone into an unexpected fecal dump mode 97% of the time ANY fat is consumed. I don’t get satiated. What do I do to become satiated, if I can’t consume fat anymore?


Fat is necessary to eat on a low-carb diet, at least long term, to get satisfied. If you can’t eat fat you can’t stay on a low-carb diet unless you have a lot of body fat to lose.

You may want to see a doctor regarding your new problems with eating fat. I’m not sure what the cause may be.

    My POS diet doctor promised me that eating high protein low carb would not raise my cholesterol. In fact, even though I didn't have high cholesterol, she promised it could only improve. After a few months of rigorously following the diet, I felt sluggish and over all not very well. I told her that continuing to eat this way was getting harder and that I was afraid my cholesterol was going up. She said it wasn't and she would prove it. So I fasted and took the cholesterol test.
    Surprise! My cholesterol went up. She blamed me and said I obviously wasn't following it.

    Why would I lie about following it? I felt like crap, had no energy, and was tired of forcing myself to eat so much protein. My weight loss had stalled and by the end of that year I had a severe case of pancreatitis. While in the hospital I was also told I had fatty liver. The doctors told me both of these were from consuming too much fat.

    Since my pancreatitis, I have eaten low fat, low simple carb, and the weight has come off, I am full of energy, and my health has improved. We need carbs. Especially leafy greens.

    My sister and various other people I know that are low carb high protein or high fat diets had to have their gall bladders removed. Anyone that follows these diets may have short term weight loss, but they are setting themselves up for long term health problems.

    You note in your first sentence that you were promised by your doctor that a high-protein diet low carb diet would cause no problems. However, what is advocated on this web site by Dr. Eenfeldt and other experts is not high protein, but high fat.

    I can’t presume to know the exact causes of your situation, but speaking in general terms, there is level 1 scientific evidence (i.e. randomized controlled trials and meta-analyses of the RCTs) demonstrating that LCHF is safe and effective for weight loss with essentially no compelling evidence that it causes health issues. That said, I imagine there could well be some specific health issue you have that makes LCHF problematic for you (e.g. if, for example, you were on any form of prescribed medication during this period).

    The problem with anecdotal evidence is that one can always find an anecdote to support one’s position, especially an anecdote about one’s own experience. Take Tommy Runneson, for example. (http://www.eatlowcarbhighfat.com) He has for the past 7 years lived on a diet of more than 70% fat. He went from being extremely obese to a healthy weight, and has had perfect blood work results on his heath check every year. Despite this, it would be unwise to extrapolate Tommy’s experience to entire population groups without proper science, which fortunately exists.

    I’m sorry you’ve had health issues, and I’m glad that you are recovering from them. If low-fat works for you, by all means continue with it.

    As for the assertion of a general nature that “we need carbs, especially leafy greens,” I would first of all point out that green vegetables are certainly viewed as healthy by Dr. Eenfeldt and the Diet Doctor crew in general, as a cursory view of the site’s recipes will evince. As far as carbs per se being “needed,” however, it is simply a fact that death from carbohydrate depletion per se is biochemically impossible. One would eventually die as a direct result of either zero protein intake or zero fat intake, but not from zero carb intake. This is underscored by the fact that there are entire population groups that survived for centuries on what is essentially LCHF (e.g. Inuit, Sami). In other words, green leafy vegetables are healthy, but not especially because of the small amount of carbs they contain.

    (A common argument, even among registered dietitians, is that we “need” to consume glucose or something that will break down into glucose - i.e. carbs or the various forms of sugar -in order for our brains to function. This assertion ignores the fact that as long as you take in enough natural fats, your liver will manufacture more than enough glucose for your brain, in a process known as gluconeogenesis. The rest of your body, including most of your brain, works fine on ketones.)

    “Why would I lie about following it?” First, please let me point out that I am certainly not saying you lied to your doctor. Rather, generally speaking it’s always possible that a patient might lie about compliance with a dietary or drug regimen to avoid being chastised by their doctor, so maybe your doctor believed this.

    Another point. I wonder if it’s possible that you may have been consuming a relatively large amount of carbs and sugar without realizing it? For example, some condiments and processed meats contain high amounts of sugar, which is the worst thing to consume if attempting to do LCHF. If one eats out a lot, it may be difficult to control this factor without asking restaurant staff about food content, which of course might feel a bit awkward for some people.

    In any case, if your current way of eating suits you and your health is improving, then that can only be a good thing. Ultimately, to each their own. Good luck!

    I was diagnosed with Type 2 Diabetes about 3 months ago. My doctor told me that I can still reverse my diabetes and referred me to a dietitian. Then, I accidentally stumbled upon Dr. Fung's video and realized that this condition can indeed be reversed. I read through dietdoctor.com's information about LCHF diet and IF as well as the foods one can eat. I shared it with my family here and in the Philippines. My family has really been supportive and this diet has become our new normal. We have experienced its positive effects. Today when I went to my doctor's appointment, she said that I have reversed my diabetes and can now be off Metformin. My hgbA1c was 6.9 and now it is 5.9 after 3 months on low carb diet. I also lost almost 15 lbs. Thank you for the information. You are God's blessing!

    After a little over 2 months on LCHF 10 pounds lighter, my cholesterol numbers got better! I have no gallbladder anyway. My A1c has gone down from 7.1 to 6.9 and that is with no mealtime insulin. But my kidney function tests continued to get worse. What can I do about this? I will quit coffee and drink even more water. But what else can I do? Thank you.

    My cholesterol is very high on this diet right now. My triglycerides are normal. What can I do about my high
    cholesterol ? I love the diet except for the very high cholesterol. Any suggestions? Thank you

    I too had normal triglycerides but my LDL’s shot up after being on the keto diet for a year. My doctor told me that about a quarter of the population she sees (she has a practice and teaches at a medical school/hospital)have this phenomenon. She said the theory is that all prople don’t respond well to a ketogenic diet but she did not accuse me of doing the keto diet incorrectly. How very condescending! (I also kept a food diary so she saw exactly what I was eating. And no restaurant food.)
    I switched my diet to Mediterranean-ish. No grains, but beans, lentils and sweet potatoes 3 x per week. No beef, but I eat bison. I refused statins, and chose to take a supplement with sterols and stanols. The next blood work showed everything had normalized.

    I no longer proselytize about my food choices. We humans are too diverse for a one diet fits all mentality.

    I hope that "Lori" follows up with another post here to let us know how she is doing. I've noticed after almost two years of keto that my bowels tend to be more loose as well.

    I am struggling with high cholesterol on my Keto diet! I also wonder at just how small your tummies are as I eat a lot of veges and beef and when I look at the plate for a Keto meal I think it is way too small. Still hungry after a meal is never good, as I feel the need to be chewing on something. 6'1" 155 pounds and type two diabetic . Blood sugars are still higher than what everyone else thinks is good. Intermittent fasting @ 16-18 hours and eating in an 6-8 hour window. Last 5 months took me from 11.2 down to 7.1 on the A1c but I was hoping for 5.8 at the most? Cholesterol is double what it should be? I have lots of energy and and IF is not a problem. Sure is nice reading about others results but wishing they were mine. I see I am not alone in the "oops we have higher cholesterol" field.
