Has anybody here experienced more impulsive behaviour as a result of intermittent fasting? More internal anger, being rude or impatient with your peers or children much more often, etc. I was on IF for 2-3 years, and while I gained a lot from the mental clarity, I also admit turning into an uneasy person within. A quick google provided a 2020 paper that tackles this same question: https://www.ncbi.nlm.nih.gov/pmc/art…

Yes, "hangry". I try to be aware of it now and then it's usually fine, and if it isn't I eat a small meal (some fruit or a protein bar)

That's not very surprising, you're weaning/rehabing from food, a lot of things can happen in your metabolism.

Not to mention serotonin is made in the gut, the brain burns a lot of calories too.

Also, most women I know are just uneasy to be with when they're hungry.

There's some rumor on the internet that IF might increase testosterone levels.

I have noticed that too in myself occasionally. I do 16:8 IF and can eat after 6pm, and I notice sometimes around 3-4pm or so, I start getting “hangry” and impatient with people. It’s not all the time, but enough to where I notice that pattern in myself.

Dr Peter Attia, who has some interesting things to say about fasting, uses a completely different definition of “intermittent fasting”. What’s being described here is “time restricted eating” while intermittent fasting is periodic fasts of up to three days.

Been skipping breakfast for about 5-6 years now, and it's had a really positive effect on energy and weight, plus helps me keep IBS in check, especially when combined with minimal sugar intake.

But the by far best thing is to REALLY enjoy a nice lunch when you've been actually hungry before. Turns out I had completely forgotten what hunger feels like before doing IF, and it's actually a pleasurable feeling when you know you're about to break your fast with a great meal.

Before IF, I would often have lunch "because it is lunch time" and didn't particularly enjoy the food. Very different when you haven't eaten for 16 hours.

For decades of my adult life I skipped breakfast, going against all conventional dietary wisdom. Having 3 meals a day just felt like turning my body into a conveyor belt that produces faeces. Now I feel kinda vindicated. A few times I traveled with a friends who did the breakfast - lunch - dinner thing and after two or three days I had to opt out of either breakfast or dinner. I remember asking "how do you even manag…

Ha! Same here, I stopped eating breakfast as soon as I became a student and kept hearing people telling me it's unhealthy... I just don't feel good when I have breakfast, I'm never hungry in the morning and forcing myself to eat breakfast is nauseating.

"Becoming easily irritated, tearful, anxious or moody" is one of symptoms of low blood sugar level.

I just started two months ago, I thought I would be grumpy because I love a big breakfast in the morning, but now after skipping breakfast I'm less hungry at 11:30 than before. So sometimes I have breakfast at 12 and sometimes normal lunch. Losing a bit more than a kg a week even though I'm still drinking beer on weekends. Just can't believe how easy it is.
