Since James Clear's blog is getting shared because it's old (2012), I will share the OG post that kicked off the intermittent fasting trend: Leangains (2010). Leangains didn't invent IF, but it did inspire more people in the last decade than anything else, including James Clear (it's the first reference he cites in this article). https://leangains.com/the-leangains-guide/

> the OG post that kicked off the intermittent fasting trend ... 2010 The Warrior Diet book came out in 2001 and it had quite a following in the 2000s. It wasn't exactly IF but it was still focused on eating most of your food once a day in the evening.

Warrior Diet recommended for your dinner meal to be a meat and vegetable stew of some kind most of the time.

Earlier quoted context omitted.

Does the amount of carbohydrates intake impact focus/concentration?

Carbs give you a sugar rush and then everything in the body goes into processing them, slowing everything else down. You can easily test it, eat something like a subway sandwich. Record how you feel. Now take the exact same sub, but as a salad (no bun). You'll feel markedly different. This all, of course, depends on a ton of individual factors like insulin resistance etc.

Your example seems to be about refined and simple carbs. Those do spike blood sugar. But a better diet would include more of complex carbs where the blood sugar doesn’t spike as badly as with a diet on processed and refined (fiber-less or low fiber) foods.

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…

The study says they fasted for 20 hours. That's well beyond what most people do. I do a 16:8, personally (which, is really just skipping breakfast), and if I don't eat by 1:00pm (which would be 17 hours), I'm a monster.

I've been skipping breakfast for over 10 years now, so I honestly don't remember how I was previously. Maybe I should starting eating it again as an experiment.

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

Intermittent fasting. A.K.A skipping breakfast

Haha this is what I thought reading the article. One thing I don't think was really touched on was exercise. Am I suppose to exercise during the fat burning period i.e. 12 hours after my last meal?

Sure, you get used it. I've been using time restricted eating for years, and workout in the mornings. It was hard at first, but I guess I adapted. I rarely feel hungry and have tons of energy in the mornings. I've gotten to where I try to plan strenuous activities before my first meal because I just feel like I have a more steady state of energy.

I've been doing OMAD since the start of this year and loving it. I'm sat at a computer all day, why do I really need to feed this body if I'm not exerting the same amount out. I find when I eat lunch now, it's a real drag, and since I'm so full after it I don't even need dinner, and can usually wait until the next day around dinner time to find that I'm hungry again. I do get a ~30 minute brisk walk in daily but no w…

My brother-in-law does OMAD. He has discovered another advantage to it. He had to go to another city for a week for work. They put him up at a nice AirBnB, and... they gave him a $60 food per diem. $60 if you're doing 3 meals? Nice little treat, I guess. $60 if you're doing 1 meal? He eats like a king every night.

Now, in this case, it may not be helping him lose weight haha!

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…

similar, but i got so good at it i got used to regularly going 3-4 days without eating at all and not really noticing/caring. as a result, my metabolism is shot and losing weight has been a real challenge. everything that went in stayed in for years.

tl:dr: shift your window. I did 18:6 for about 6 months a decade ago and noticed the hangry effect (as did my wife and kids!). I went from 232 to 190 lbs though, placing top 5 in triathlons, so the method undeniably works. It's been 10 years and I found myself back at 225 and decided to get back on the IF wagon in December, with one modification: I stop eating at 9 pm and start at 3 pm, so by the time I encounter my…

Curious what your initial eating window was?

I started intermittent fasting in September and I thought I would do it only to lose my corona weight gains. But by now it's a lifestyle for me that has so many benefits. To be fair, breakfast was never that important to me. I typically start the day with a few cups of coffee with milk and going to black coffee without milk was and is funnily the biggest price I have to pay.

To cut the junk food after 8pm has so many positive effects on my overall wellbeing - and let's face it, it is always bad food we eat at night, nobody ever comes up at 10:30pm "hey look at that nice apple."

I'll turn 47 next week and I have an almost perfect BMI again - something I hadn't had for almost ten years of so. And I still eat too much cake and chocolate in the afternoon and don't really starve overall. The only thing I can't get used too is the black coffee in the morning but that's a small price to pay.

Intermetting fasting is not a diet, it's a lifestyle and that's why it works so well. So overall I can just recommend it.
