I do (paleo) vegan fast every year. I eat ad libitum, but no animal foods. Gluten and refined plant oils are also excluded, as they are during the rest of the year.

The fast is a welcome stressor and forces some variability into my eating habits. It is also an opportunity to assess effects of various types of foods on my brain.

This year’s 42 days fast confirmed findings from the last year.

Going vegan hurts my choice reaction times. The mean reaction time deteriorated by more than 4 milliseconds. Almost one standard deviation move (5.9 msec.).

My condition worsened with time. Note the sharp drop in the reaction times immediately after the animal foods reintroduction. The negative measured effect as well as subjective weakness and clouded mind went away immediately after the first steak.

The graph shows the average time of every finished set of my choice reaction times test. Red dots are the test sets during intervention, blue during control months. The black trend line is a 7 day (14 sets) moving average.

      choice reaction time app (app in R). 2 sets of 32 correct answers every day in the afternoon. random single digit number flashed after randomized time. correct answer = hit the right key.

    Am I missing something? It seems like the data he is showing does not support the article’s central thesis:

    His cognitive ability didn’t decrease when he went vegan, but when the switched from vegan BACK to animal products.

    He says as much: „Note the sharp drop in the reaction times immediately after the animal foods reintroduction.“

    If you look closely at the data points, his cognitive ability seemed to go up as a result of his vegan diet.

    Is this high level vegan trolling?

      the lower the number (reaction time in milliseconds) the better

    Next time you might try supplementing creatine when on vegan diet. Creatine is in short supply outside meat and small amount is required for human brain to function 100% (and also for many other bodily functions).

    A lot of professionals now recommend supplementing creatine when on vegan diet.

      thanks for the suggestion, but in the context that I consider this change once a year as a welcome stressor I don’t want/need to add anything highly processed.
