Hello all. I’m struggling with brain fog around hour 13. I don’t feel hungry, it’s the cognitive function that’s the issue. The past few days I’ve tried numerous things to help: salt and potassium, coconut water, and MCT oil. Nothing...
After encountering numerous articles and videos comparing the cognitive benefits of fish to fish oil (I am not yet adept at deciphering scientific articles), I have become increasingly skeptical of the benefits of the former. Many of these sources either...
I'm mainly asking because there seems to be contradicting information out there. I see a few articles mentioning IF helps mental capacities, whereas others mentioning 'breakfast' boosts cognitive/memory function. Is it possible that technically both provide benefits just using different...
Got an exam tomorrow and wondered if there was an optimal food you should eat, regarding cognitive performance, concentration and attention. I heard that walnuts are good for your brain but I havent seen a study for it

My dad has been doing 3 day fasts at least once a month since his PhD days as a way of getting “centered” and improving focus. I just got started on day 3 of my fast (water and pickle juice) and...

I just finished reading an article on the damage ultra-processed foods do to cognitive performance. Common ultra processed foods mentioned were commercial bread, ice cream, chips, fruit flavored yogurt, instant soups. At what point do they drop off in being ultra...
