Study

Effect of intermittent fasting on circadian rhythms in mice depends on feeding time.

http://www.ncbi.nlm....pubmed/19041664

Revealing that only daytime feeding produced the desired affects.

 

Some Intermittent fasting gurus, the ones that say to skip breakfast, claim the evening meal is the one we are 'meant' to eat.  I'm not hungry then. Besides, it makes sense to me to eat during the hours I'm active.  I think the most important thing is to that you spend a lengthy period not eating, whatever time of day you do it.

My boyfriend (after I've FINALLY managed to convince him to clean up his eating habits) has developed a consistent pattern of eating similar to intermittent fasting. I think I read somewhere that it's called the warrior method or something. He basically eats once a day, around 6pm and he'll eat a rather large meal. Then, he won't eat again until 6pm the next day.

He never had bad skin to begin with, but has lost a significant amount of weight doing this (and yes, he eats enough calories and is super excited about all of this newly discovered energy of his.

I've done intermittent fasting before, but found it much easier to simply stick to caloric restriction.

[alternativista]

Yeah, the warrior method is more extreme in which you eat all your meals within a 4 hour period and fast the rest of the day.

Intermittent Fasting may reduce hyperproliferation/hyperkeratinization:

Modified alternate-day fasting regimens reduce cell proliferation rates to a similar extent as daily calorie restriction in mice

http://www.fasebj.or...22/6/2090.short

This study is comparing the results of calorie restriction and alternate day fasting, and a modified method in which calories are reduced 85% on the alternate days. Apparently all methods produced the result of reduced cell proliferation. This study was about cancer so it mentions various cells--"keratinocytes, liver cells, mammary epithelial cells, and splenic T-cells"

Epidermal cell proliferation decreased (P<0.01) by 29, 20, and 31% in the CR-25%, ADF-85% and ADF-100% groups, respectively, relative to controls.

And

Insulin-like growth factor-1 levels were reduced (P<0.05) in the CR-25% and ADF-100% groups only.

So is the reduced cell proliferation soley due to the reduction in IGF-1? And is that totally due to improved glucose metabolism or is there an additional pathway?

There's nothing extreme about a 4 hour window, I do it because it's natural for me. I get up, go to work, by the time i'm home and ready to eat it's 6pm and around midnight i'm off to bed.

I do extremely active work in a warehouse, and eating lunch makes me too sluggish, physically and mentally. I enjoy food much more if I can sit down afterwards and relax.

So what do you do during lunch at work then?

I can never eat alot during lunch when I am at work. Or really enjoy it.. I feel rushed or something and not relaxed. I also can enjoy food more at dinner times because I cam alot more relaxed and I can eat alot

[uncle buck]

Sit in my car and write, or just lie down.

Sorry to reply to a somewhat old post, but I hadn't noticed anyone else mention this before. I thought I was crazy (or broken) for feeling crappy after lunch at work. It doesn't matter what I eat, if I eat a significant amount I feel tired and almost lucid. To top that off, I think it's intensified by a bigger breakfast.

For instance today I had sausage and eggs cooked in lard for breakfast and some coconut milk. For my lunch break I ate a can of tuna with some homemade mayo and I feel like I need to take a nap right now. I felt fine before lunch. My eyes are actually hazy (and I need to stare at a computer, how fun).

So yeah, I'm gonna stop thinking about it being weird and try skipping some meals tomorrow.

[betsy91]

So is fasting bad? I keep hearing mixed reviews and I'm starting a three day apple fast.

[CocnutCaramel]

this is a really cool thread. i think i've done this at least once a week for a long time without thinking about it. I, like alternativista, am hungry and in the mood to eat between about 7am and 5pm. Like today, I had my "dinner" (which looked more like breakfast) at 5pm, then I went to the gym at 7pm, got back home at 9pm and that's way too late for me to start preparing food.
So if i decide to sleep in a bit tomorrow morning i get 16 hrs of fasting, or 14 if i get up early. Skipping dinner is really no biggie for me, as long as i've had enough to eat during the day. I much prefer breakfast-snack-big lunch-early dinner/snack. And I don't get very hungry after working out in the evening. I know you're supposed to eat afterwards, but i'm just not hungry and i hate eating when i don't feel hungry (no worries, i get plenty of proper healthy foods during the day)

There's also evidence that working out on an empty stomach is also beneficial. There should be info on that here or in the exercise thread that's primarily about interval training plus moving around a lot during the day, all day everyday which mimics the kinds of activity our bodies evolved doing and our processes were designed to fuel. http://www.acne.org/...se-t275783.html

i'm not sure if you are aware, but the movement of intestinal muscles can be partially stimulated mechanically, or in other words, vibrations or by applying pressure to them, can further stimulate peristaltic actions, beyond their normal movement. so it seems that any type of physical activity would contribute to regularity, which is a very healthy state for your intestines to be in, it seems the way the human body is designed, it would be beneficial to eat our food before physical activity, so as to aid in the digestive process. perhaps physical activity isnt advised directly after eating, but within an hour or so after eating a meal.

There should actually be physical activity just about all day long.

yea, the modernization of society has changed normal human behaviors quite a bit, i think like pre industrial revolution about 95% of all people were considered farmers as an occupation, now it is the exact opposite. and before that we were hunter/gatherers, now we are ummm, sitters talkers and thinkers?
with a few exceptions i suppose.

even when i go out walking in the neighborhood, im like, the only one out there most of the time, where the hell is everybody? oh yea, they are "driving" somewhere.
as much as i love science and technology, i despise the opportunitys it gives us to disrupt the natural cycles of things, even the biological cycles. night shifts, no excercise, mercury and lead contaminated foods from fossil fuels,acid rain etc.

It;s always been amusing over the decades whenever there would be a brief walking fad in which you'd see everyone out walking and then a few months later they'd all disappear. My mom has always walked a lot and so I grew up that way.

Yep. I've started to think I don't want to sit at a computer anymore and maybe I should find someplace and open a store. Ideally an open air one. I wish I could find one of these towns that are trying to rebuild in a part of the country I want to go to. Like this one, http://www.treehugge...s-are-best.html but not quite that far north.

[LiveLaughFart]

I fast for 15 hours . I stop eating at 10pm and go to sleep and start eating at like 2pm the next day. But I don't go to sleep until 5 am and wake up at 2pm the next morning (or afternoon for most people)...It's so hard to make yourself go to sleep. I wish i could just take a pill and fall asleep but that wont be healthy.

[alternativista]

Well try getting up earlier than 2pm so you are tired earlier. And dim all lights in the evening. Avoid bright artificial light after dark. Get out into bright outdoor light in the daytime as much as possible. This is how you make the neurotransmitters that put you to sleep at night and wake you in the morning.

Somewhere around 10pm to 2am is when the deepest and most important sleep occurs. Although that probably varies slightly with time zone, latitude and season. That's when you need to sleep. And it is extremely important for your health.

Melatonin and valerian root have helped me in the past with getting a good night's sleep. The lower the dosage of melatonin the more effective it is, they're both supplements that don't cost very much.

Do you need to have such a crazy sleep schedule because of work or something? If not, I'd say def. try to work on sleeping when it's dark out. Exercise always helps me sleep well. And darkness. Dark, dark room is a must. When I lay in bed playing with my phone I never fall asleep. It's also why I don't have a tv in my bedroom. (Well ok I never used to, now I do but just with a PS2 and VCR hooked up for minime, no cable).

isnt melatonin a tanning drug?
I am totally against supplimentation because i dont want to ruin my body chemistry and don't know forsure if i have any deficiences.
But i think not being able to sleep has to do with what i eat. like whenever i eat rice I fall asleep right away. But I can't eat rice cuz it will break me out.
And no i dont have work or school to attend to at night...before I go to sleep, I have a big sense of not being ready to sleep, I just don't want to go to sleep and don't have that tired feeling until about 5 30 a.m. Once I get that tired feeling, it's easy to go to sleep right away.

Melatonin, not melanin. 10 hours of sleep is far more than necessary. Once in awhile is fine but are you sleeping that much regularly? Because that would make sense as to why you can't fall asleep to begin with.
