Lots and Lots of Saturated Fat

Just shy of three years ago I embarked on a totally new nutritional approach. I used to eat a "traditional" high-carbohydrate diet full of whole grains, fruits, and vegetables. I didn't obsessively avoid fat, but consciously did try to eat much more carbohydrate than fat. My switch was quite polar in nature: I not only flipped the macronutrient profile on its head, but I focused on making the primary source of fat what many in the past few decades have considered the most villainous kind of fat. That is, saturated fat.

After a year of this nutritional protocol I was thrilled with the differences I saw in my recovery, training, and racing, and also in my daily life. When I got my lipids measured, I was thrilled to see that my numbers had improved after the dietary switch. Of course, it was still met with skepticism by some. After all, saturated fat has been shunned for decades; I didn't expect most people to run to the store and stockpile butter and coconut oil based on my example. Still, I thought it would be valuable to share my results for other people who struggle to find a healthy alternative to a more traditional nutrition protocol.

I've been excited to get my biomarkers measured again and see what might have changed after continuing on a high-fat protocol for a longer time. I am happy to share my latest biometrics below, and even more happy to see continued growth in the state of my lipid profile. Don't miss my previous biometric results comparing my 2011 high-carb diet to my 2012 high-fat diet.


As you can see, my HDL and LDL readings are doing just fine despite saturated fat being a major component of my diet. I always find these visits humorous because the nurse is always shocked at my HDL and LDL scores after I tell them my diet. Especially when you compare the recommendations at the bottom of the sheet to what I actually do.

A brief summary (it's kind of hard to see on the photo):
  • "Limit your salt intake"
    • I consume high amounts of quality salt (Himalayan sea salt), sometimes as much as 8 grams a day.
  • "Include 7-9 servings of fruits and vegetables each day"
    • I rarely eat fruit. I never buy it for the exception of racing, soI'll occasionally eat it during races, or if I am randomly offered some berries or melon. I used to eat tons of vegetables of all kinds. Recently (last six months or so) I have really focused on specific vegetables and scaled back the volume of vegetable consumption. Too much fiber can wreak havoc on the digestion system, hampering micronutrient absorption. The majority of my vegetable come from lower-fiber sources such as spinach or seaweed. I occasionally have onions and peppers with eggs, liver, and bacon. I still eat carrots and broccoli, but in much smaller quantities.
  • "Drink plenty of water"
    • This is the one suggestion I follow. However, I don't mindlessly go out of my way to pound water. I drink when I'm thirsty.
  • "Eat whole grains and nuts"
    • I avoid whole grains like the plague. I am not clinically gluten intolerant, but do recognize the more subtle repercussions from grain consumption. I do eat nuts, but not in the traditional sense: I consume them in the form of Yumbutter. (They even have a product made with chia seeds!) I typically melt a stick of butter and mix it with 1/4 to 1/3 jar of Yumbutter in order to raise the saturated fat content. This calorie-dense concoction can provide multiple snacks and/or meals.

  1. Thanks for the info. Always interesting to read. If you don't mind sharing, what is your take on alcohol consumption? Do you have wine or beer ever (obviously high consumption is not going to be a positive nutrition component)?

    1. Hey David, thanks for reading and posting! I rarely drink alcohol, but I'm not so rigid that I never drink it. It's kind of like you said, not ideal, but a nice treat every once in a while. Typically, I avoid it entirely during sections of the season where I have a string of races all relatively close. Its these times I need to be really dialed into recovery.

  2. Hi Zach,

    You may be interested in this recent editorial from The Lancet about the complexities of SFAs- it seems a bit complex... and not well understood.

    1. Hey Robert, thanks for reading, posting, and sharing the article! I love seeing these things. Dr. Stephen Phinney (co-author of Art and Science of Low Carbohydrate Living and """""Performance) actually has credited his switch to an very strict ketogenic diet to reducing his need for diabetes symptoms. I think he is off all previous meds. This would be right in line with his findings.

  3. Hi Zach great read and I couldn't agree more on your diet. I've found my health and speed have both improved in Ironman racing since making the switch a year and a a half ago. Keep smashing those records mate

  4. It is fun to follow your training and racing success Zach and think "that's my bro!" I love my Altras and am also successful with a similar nutritional approach. 113 pounds and counting using a high fat low carb diet and running for me. Hard to argue against transformed life and World Records.

    1. Hey Josh, thanks :) That's amazing, 113! Something clicked for you then. It's so funny how finding the right protocol can do so much for overall health. What pair of Altras are you running in?

    2. A huge relief to find an approach to eating and activity that works for me. I tried damn near everything, failed for years. I run in Lone Peak 1.5s and One^2. Love them both. I have a pair of Lone Peak 2.0s ready when the current 1.5s wear out. Love the One^2 on the road. Even though I am still 235, they are enough cushion and I feel fast! For the first time in years I am overcoming severe achilles tendinopathy with improvements in my fitness, form, strength, and Altra shoes.

  5. Hey Zach. I like your approach being willing to try new diets, and allowing that they may not work for everybody. I wonder if, in addition to individual differences in responses to certain diets, there might be benefits that we gain or lose at certain points in life. For example in one of the recent National Geographic articles on food, a research said "red meat is great, if you want to live to 45", because the body's immune response to red meat changes as we age. So tracking how you are doing now and how you are doing in 10 years from now will be good science!

    1. Hey Steve, thanks for reading and commenting. I am familiar with the red meat after 45 argument. I'm not too convinced. Check out the podcast episode on Ben Greenfield Fitness. He does a really good job of describing why it is not a very plausible theory. I will continuously be monitoring my bio signals and looking at ways to improve.

  6. todd and i were talking about your diet at lapham the other week when you were there. we weren't formally introduced so i apologize for now knowing who you are (i didn't before he pointed you out). i am incredibly interested in your diet because i've suffered from consistent gi issues which have been compounded since i've upped my speed and mileage. i've found that if i keep my diet very very simple it's better. any chance you'd post a typical meal plan for the week? thanks! next time i'll introduce myself. :)

    1. Hey Nikki, thanks for reading and sharing! I'm hoping to get up to Lapham a fair bit this Fall, so I'm sure we will meet at some point. I have posted some samples in the past. I usually hesitate to do it though, because usually people hyper analyze it and assume a daily sample or weekly sample is exactly what I eat every week all year round. This leads to a bunch of misinterpretations. It's kind of funny though. Usually I get a handful of emails telling me I'm nutritionally deficient in one nutrient or another :) I also hesitate to post sample weeks, because my diet has evolved and will likely continue to introduce and subtract some food sources based on what I am currently focusing on athletically. The internet is in ink :)

    Your LDL was ZERO?? Are you sure that wasn't a mistake

    1. The doc likely made a mark to indicate his level was below the 100 mg/dL and a non-issue. It is impossible to have a 0.

  8. Hi Zach,

    My HDL is over 100 and my LDL is within normal range. What particular foods contributed to your LDL to be zero?

    1. You can't have an LDL at 0. LDL is necessary and important in our bodies and is not necessarily "bad".

  9. Hi! Newbie at trail running here but low carb high fat eater for most of my life (not a studied decision, just personal taste - i hate feeling hungry and carbs make me wanna eat every 2 hours. Anyway, i'm increasing my distances and i see people obcessing about food intake during longer trails. Is that really necessary? And if so, are there any fatty or slow carb options or are those simply too slow to be of any use? Im used to hicking all day without getting hungry so was hoping i could do fine on running as well?
