It's a bit to do with a change in diet and lifestyle to accompany the eating window but there is definitely something else at play as well.

The human body is an amazing machine and it has all sorts of abilities that we are unaware of. When you starve, your body starts shutting down non essential things first, starts pulling nutrients from everywhere it and limiting activity. Starvation has both a physical and mental element to it - both during the process and following it.

Intermittent fasting has been demonstrated to start a regenerative process in the body. It triggers cellular autophagy, which is kind of like running a cellular defrag.

There have been a lot of studies lately that look into the regenerative aspects of deep sleep following a serious injury - I sus that's the same system behind both things.

In response to the stress of not eating as usual, the body reacts. The mind does too. It sucks while you are starting it but it's nice to be able to know that you can skip of day of eating and be fine. After eating a big dinner and a good night's sleep you should have more energy and feel better for no real reason. I sus this has to do with how we ate while we were evolving - life was just a cycle of involuntarily intermittent fasting.

Unless you do strenuous activity all day - food is energy, you will be wore out of you do too much. The food you first eat after matters too!

Don't make a donut or highly processed/sweetened food the first nutrients after fasting - you'll feel like you ran a marathon. Simple carbs and protein - rice and black beans or oatmeal with seeds is typically what I do.

Everyone is different tho - whatever works for you! All the best of luck, sorry this is apparently my rant for the day - better topic than normal

I've been following Jason Fung and "intermittent fasting" for six or seven years.

I notice that the specific wording "time-restricted eating" has gained popularity in the past couple of years, possibly because "time-restricted" is less of a red flag to the public than "fasting," which may bring up some emotional baggage.

The reason for renaming is just speculation on my part - what's clear is that the eating protocol is the same, only the wording is different.

when i hear "intermittent fasting" i think once or twice a week. Also it's not a silver bullet, but it does "shrink the stomach" a bit if you are mindful of the volume of food you consume to break the fast. better to, as your sibling said, break with a light meal with all the macronutrients and a decent chunk of micronutrients and vitamins than a lumberjack's breakfast. Or if you break in the evenings, the buffet is probably not ideal.

Maybe when people realize they don't need as much food as they thought - especially grasses (sugar, wheat, corn, specifically), they can "change their relationship with food."

or just ozempic i guess, what do i know.

hey i wanted to ninja and let you know i have no problem with what you or sibling said, at all. I'm just speaking to the topic, not trying to argue. I realize a skim makes it seem like i was disagreeing!
