What a great article! I run faster for short runs but can’t imagine running fasted anything over 4 94 5 miles. I sometimes worry that society’s newfound obsession with fasting will negatively affect future endurance athletes - a discussion for another day

Interesting. I rarely run fasted. When I do it's an easy short run in the morning.

I run fasted pretty regularly (not for performance benefits, but because I usually can't be bothered to eat something early in the AM before I run) and this is thought-provoking. Thanks for posting it.

That's really interesting. I personally cannot run fasted for more than 5K, and even then I don't feel good. Now I feel less like I "should" be training fasted.

Interesting article but I don’t see anything so worrying that it would change the way I personally exercise. I always run fasted, anywhere from 3-10 miles 3-4 times a week for the simple reason that I don’t like the feeling of food sloshing around in my stomach while running. I usually run in the late morning or around noon (no breakfast) and just eat a slightly larger lunch immediately after. I’m not really interested in increasing my speed or pushing myself beyond my limits, I just run at whatever pace feels good at the time because my priority when I run is simply to have fun. I lost my excess weight by eating less and moving more over 6 years ago and have maintained ever since. I have a healthy relationship with food and my bmi is on the higher end of normal (23.3) but I see how working out fasted for someone who did have disordered eating or a much lower bmi could be an issue or if they were a competitive athlete pushing themselves too hard. A couple years ago when I was already in maintenance and a seasoned runner, I tried keto out of curiosity and for the supposed satiety effects, I was in ketosis for 6 months straight and my running did suffer. I was still able to run but felt tired and heavy like I was running through molasses every time. I stopped the keto after half a year and as soon as I reintroduced carbs my running immediately went back to normal even though I continued to run fasted the carbs still made a huge difference in my exercise performance. Also the keto never helped with satiety for me, but it was an interesting experience to try (once! but never again) and helped me get to know my body better. I don’t think the article mentions what kind of specific diets, if any, the athletes they studied were on but that certainly might make a difference.

I always used to train fasted for a similar reason - simple timing issues. If I had time to eat I would, but running first thing before work meant I didn't always have time for food to settle.

These days I do a lot more evening training and I'm doing more cycling which is easier to eat before/during so I do it less. my new coach sets me one fat adaptation ride per week usually (1st hour fasted, some food after that). I am fine with it because I have a decade of being used to training fasted, but it's too early to tell if it's helping with anything.

I'm reading roar at the moment and had spotted the bit about fasted training.

Good article, very interesting.

And I think I'd say that even if it didn't validate my personal extreme hatred for fasted workouts (of any notable intensity), in which I both underperform (compared to my own non-fasted pace metrics) and feel awful.

Some of my endurance athletes train fasted. Other than that there isn't any benefit other than preference.
