    or are you saying that the person would have more energy available (in the form of stored fat) to sustain the effort?

    I know that was my experience with distance running when I switched to the ketogenic diet. Instead of hitting that wall toward the end of my run, feeling like I was pushing so hard those last few miles, like my reserves were just about empty, that feeling completely disappeared. There was no wall, there was no fatigue or hunger afterward. I literally felt no signal to stop and rest except maybe my joints getting worn out. It really amazed me. I have seen evidence that fat metabolism (being in ketosis) actually increases the number of mitochondria in your cells. Apparently fat metabolism is easier for the mitochondria, it creates less oxidative stress, and it inhibits cellular apoptosis (programmed death). Most of this research is related to fasting and increased longevity in animal studies. However it works, my experience is that it works incredibly well.

    Just FYI to others in the thread. My experience was the opposite. I can run fueled by carbs and could easily run a half marathon without fueling. Felt great afterwards.

    When I am running keto...anything after mile 7 or 8 and I hit a wall. Everything feels like garbage and I want to stop.

    Just wanted to share my anecdotal evidence to contrast with what was shared above. I'll also say that the running group I frequent...who almost everyone in it has completed a marathon (brats, right?) that carbs are absolutely the ideal fuel for them.

    I've been running since 8th grade and got most of my first nutrition advice from Jeff Galloway's book. He was all about eating carbs and limiting fat. I remember his rationale. More calories per gram in fat, it gets stored immediately while you're body uses more energy to breakdown and store the protein and carbohydrates. Seemed reasonable to me at the time (as I knew very little then about nutrition), but it's outdated advice now. Running on fat is very different; however, it can take weeks to get over the keto flu and get fat-adapted enough to experience it fully. Running or any kind of exercise in early ketosis is very difficult.

    LOL. I was 6 months keto when I was running on fat.

    LOL. I was probably 2 months in at that point. Over 3 yrs later and still going strong. Last time I timed anything, I ran 3 miles in 21 min. I know that's faster than I ran 3 miles in high school, so something is working for me :wink:

    In my experience, most serious runners as well as most people have no idea about the benefits of ketosis let alone what it is.

    I see no benefit to keto especially for long distance running. I found it quite painful.

    You and my experience would be different then. I enjoy being around curious and educated people. And those who run 20 to 40 miles a week would be people who I would listen to about their experiences. But different strokes for different folks. I'm also incredibly knowledgeable about ketosis and my experience is the same as those runners about the preferred fuel. It's fine for short miles, but not for anything with decent mileage, etc. You mentioned 3 miles in your above post...exactly.

    Interesting. I recently read a spread in Runners World where a distance runner experimented with low carb. She had the exact same experience as me: sustained energy with no wall. She gave it up afterward though because the diet was too restrictive for her, but her experience and writing seemed pretty unbiased.

    Her words:

    I loved the steady supply of energy that fat adaptation gave me, and I’m the leanest I’ve been in several years. But I missed drinking beers with friends and polishing off midnight pizzas with my husband. I hated feeling guilty about grapes. And I pined for cake. A lot.

    Let's say net carbs and gross carbs are the same...for comparison purposes

    @Expatmommy79 a carb is a carb when it comes to nutritional ketosis based on the literature and being in a state of nutritional ketosis most of the time for the past 1.5 years. The main thing is to keep the carbs <50 grams daily and of course to keep protein on the low side of medium and make up the lost carbs/protein with non grain fat sources.

    That's great for her and you. I experienced quite a wall...as did another poster in this thread. I don't mind keto workouts for short intensity or for shorter distances, but longer distances it is really not optimal. Not sure why you feel the need to poo poo my experience. It is just as anecdotal as yours and the women in that article. Keto on and let others do what works best for them when it comes to fueling their workouts, mkay?

    Hmm, sorry, not sure where you got the poo poo vibes. Just sharing the knowledge like you. I don't think I actually said anything at all about you.

    What works for you is great. What works for others is great. The assumptions you made about my own keto journey (wrong) and then saying how uneducated those runners who share my view on let me know pretty clearly.

    You do you. My experience with keto running and others I have talked with...is pretty abysmal. Glad you like keto running. Doesn't mean it is ideal for all.

    Not sure how I made any assumptions about your keto journey, as I said absolutely nothing about you.

    Let me reiterate my other comment for you: In my experience, most serious runners as well as most people have no idea about the benefits of ketosis let alone what it is. You said that your experience is different because you "enjoy being around curious and educated people." I also didn't respond to the derogatory implication behind your comment.

    All the friends I run with and races we run in together are all about getting energy from food. Carbs are beautiful. I think you are mistaken about the benefits of ketosis.
  • HornsbyHornsby Posts: 10,372Member Member Posts: 10,372Member Member
    I gotta say, I don't know a single cyclist that is keto. That goes for my group as well as pros. With the risk and drugs these guys will use to become optimal, I can't imagine they haven't heard of or experimented with it.

    Carbs are beautiful. Blueberries, kale, broccoli, spinach, salad, tomatoes, carrots, onions, celery, strawberries, walnuts, almonds, peanut butter, yum! I love me some carbs on the ketogenic diet <3

    But you are talking of a minuscule amount of carbs. Big difference.

    Just FYI to others in the thread. My experience was the opposite. I can run fueled by carbs and could easily run a half marathon without fueling. Felt great afterwards.

    LOL. I was 6 months keto when I was running on fat.

    LOL. I was probably 2 months in at that point. Over 3 yrs later and still going strong. Last time I timed anything, I ran 3 miles in 21 min. I know that's faster than I ran 3 miles in high school, so something is working for me :wink:

    That's great. Doesn't change how carb running is absolutely better for me and keto running for longer distances gets me to hit a wall. :wink: :wink: Most serious runners I know....agree, but glad keto running works for you.

    In my experience, most serious runners as well as most people have no idea about the benefits of ketosis let alone what it is.

    You and my experience would be different then. I enjoy being around curious and educated people. And those who run 20 to 40 miles a week would be people who I would listen to about their experiences. But different strokes for different folks. I'm also incredibly knowledgeable about ketosis and my experience is the same as those runners about the preferred fuel. It's fine for short miles, but not for anything with decent mileage, etc. You mentioned 3 miles in your above post...exactly.

    Interesting. I recently read a spread in Runners World where a distance runner experimented with low carb. She had the exact same experience as me: sustained energy with no wall. She gave it up afterward though because the diet was too restrictive for her, but her experience and writing seemed pretty unbiased.

    Here ya go!

    Her words:

    I loved the steady supply of energy that fat adaptation gave me, and I’m the leanest I’ve been in several years. But I missed drinking beers with friends and polishing off midnight pizzas with my husband. I hated feeling guilty about grapes. And I pined for cake. A lot.

    Here's another you might be interested in.

    As I’ve mentioned, I’ve been living in this world for several years now. I’ve raced 14 ultramarathons on a Low Carb/High Fat diet and I have started most of these races in the fasted state. I’ve won 5 of these ranging from 70km to 200km in length. Doing this has taught me a lot . Far more than I have read or studied. Imagine turning up to a 200km ultramarathon without carb loading, without eating breakfast, without sports drinks or electrolytes, without my gram’s of CHO/hr calculated or “hydration” needs calculated … in fact, without doing what most of the books tell you to do or without what my qualifications had taught me ? I have lost a lot of skin mind you and put myself in a box on a few occasions. But this is how you really learn about the body, as if you don’t figure out how to get yourself out of the box, than you are really screwed. The information helps of course, and the theories can be help the comprehension but the doing at this extreme is where you get to understand things.

    All the friends I run with and races we run in together are all about getting energy from food. Carbs are beautiful. I think you are mistaken about the benefits of ketosis.

    Carbs are beautiful. Blueberries, kale, broccoli, spinach, salad, tomatoes, carrots, onions, celery, strawberries, walnuts, almonds, peanut butter, yum! I love me some carbs on the ketogenic diet <3

    But you are talking of a minuscule amount of carbs. Big difference.

    Actually no, I can eat far more food than I would if it was higher carb. I never go hungry, and I eat what I want. 1/4 cup of walnuts has 2 net carbs. 1 cup of blueberries has 13 net carbs. Cover than with some heavy cream. I'm so full, I can't imagine anyone would need to eat more. Low carb real foods are incredibly satisfying.
