Fasting May Fix Jet Lag 131

Posted by kdawson
from the lost-in-translation dept.
stoolpigeon writes "Reuters reports on a Harvard Medical School study on sleep patterns and how they relate to food. Researchers already knew that the sleep patterns of mice would change to match the opportunity to feed, but they did not know the mechanism that enabled the change. To find out, they looked for the part of the brain that was involved. They bred mice without a certain master gene that regulates the body's clock, and then targeted various parts of the brain with the gene, delivered in the shell of a virus. The results may, among other things, provide a new method for preparing to deal with jet lag: 'A period of fasting with no food at all for about 16 hours is enough to engage this [alternate body] clock,' the lead researcher said. The study appears in the journal Science."

          The real issue is which airline you are flying. Some are better than others. Unfortunatly, because national governments like to protect the dinosaur airlines from competition by better airlines (overseas carriers looking to enter the market, startups who think they can draw business away from the big boys), often the airlines that have the good stuff (better food, better seats, better entertainment etc) dont fly the route you want to fly.

          If aviation worldwide was deregulated and e.g. foreign airlines such as Singapore Airlines and QANTAS were allowed to fly domestic routes inside the US, the dinosaur airlines that offer the crappy service like United and American would have to get better or go bust.

            There's plenty of competition within the US as it is. You have to ask yourself why none of them have wised up and started offering better service. In fact the one that are doing the best tend to offer the worst amenities.

            The reason is that airline customers care about price above all else. I recall a study (no, I don't have a cite, sorry) where people would ignore significant differences in amenities for as little as a $5 difference in price.

            This is why service sucks everywhere. If an airline cuts food from a price and this allows them to undercut their competitor by some trivial amount, they get a significant influx of new customers. It becomes a race to the bottom, with costs cut on amenities everywhere to allow for reduced ticket prices.

            Because of this it's unlikely that Singapore Airlines or QANTAS would make much of a difference in the US market. They'd either have to do the same stuff in order to compete or they would get priced out of the market.

Maybe I'll see what kind of plane I'm flying on so I can go to a third-party site [seatguru.com] to see which seats are good. United had some of their economy seats spaced out more for better leg room for a while, but I never saw anything about which flights had that and which didn't.

              What are these magic amenities that will make a 4 hours flight with no leg room more bearable for an extra $5?

              People will save $5 on a flight choosing a cheaper one because in economy there's basically no difference. What are the amenities? Coke v Pepsi products? Seats without tears in them? New sickbag in every seat pocket?

              I'd *gladly* pay a smaller amount more for a bit more leg room. I'm not a big person (5'9") but am cramped in economy seats. But the only choice is biz and/or first class, often at 5-10x the price of the economy price. There's no middle ground, so people choose the cheapest economy they can.

              I went from RDU to SJC for about $230 last month. I could have paid up to $500 for the same trip on a different carrier, but still 'economy'. I've flown economy on all the major carriers at one point or another, and they all have the same size seats and basic service, so why pay double for the same thing?

              I almost tried JetBlue, but the scheduling wasn't even close to what I needed, so I'd have had to go the day before and get a hotel for another $200. Plus the JB ticket was $650 or so - close to 3x the price I paid. I've heard good things about JB, but not good enough to pay an extra $620 for my trip.

              If an airline would promote their 'amenities' for the extra few dollars, maybe I'd give it a try, but there's few amenities save legroom that can make a 5 hour trip worth any extra amount of money.

And if we *all* would be willing to pay that new price, then biz would go up accordingly and that new higher price would be the low bar for pricing, based on peoples' willingness to pay it.

    Jetlag has not proven to be a significant issue with me or any of the people I have travelled internationally (as in, more than 5 time zones in one go) with. Is it only a significant issue to those who are changing timezone on an almost daily basis?

    Typically if you're travelling west, you just get an hour's nap (or not) on the plane, but stay up an extra 5 - 8 hours or so (or less and go to bed a bit earlier). That's pretty easy to do. You will tend to wake up a little earlier than normal, but that's not a massive deal.

    Travelling east is more difficult, as going to sleep 5 - 8 hours earlier is usually impossible (or impractical if still travelling) so you need to stay up an extra 8 - 12 or so hours, go to bed early, and get extra sleep that night. In both cases, you wind up waking up at roughly a sensible time.

    Perhaps there is a significant group (who I do not travel with) who are unable to stay up for 28 hours on the odd occasion when it's necessary to resync with the local time zone? Or is it that if you do it, say, every week, this technique becomes totally impractical?

      Many factors go into jet lag, including age, health, and sleep deficit. If you're unhealthy, or are already running up a sleep deficit, you're going to find it harder to adjust.

      The purpose of the trip also comes into play. If you're traveling for business, jet lag is like working on 2 hours sleep. If you're traveling for fun, jet lag isn't nearly as bad.

I should mention, however, that I initially only came back 5 of the 8 timezones, adjusted, and then went the other 3, so that's another reason it was easier.

      Try a flight like Europe - Australia doing that --- not eating for ten to twelve hours is one thing. You do it every night! Not eating for twenty-four or more hours is killer.
  • Well, at the moment I'm on a completely nocturnal sleep schedule, however in the near future this needs to change. So I shall plan to test this within a few days! However, the wording of the article is not entirely clear. If I understand it correctly, I should not eat during my normal functional hours while staying awake until the appropriate time, and my body should adjust to a more normal schedule, correct? Ah, well, guess I'll find out. Sounds a bit unlikely though.
  • Of course, jet lag is much less of an issue WHEN YOU'RE STARVING!

    Oh well, so long as I can drink all I want....
  • If anyone wants to investigate whether there is a similar link between sex starvation and jet lag, I could suggest a couple of married friends who'd be ideal candidates for the study.

  • I fly from the States to Korea fairly often and this works each time i do it. There are 14 hours differences from States to Korea. It seems to work on both ways i fly.
    1. Before you fly: get less than usual amount of sleep. Eat normally, go to gym live normal.
    2. During the flight: Take a short nap as if you would do on the day you had little sleep. and get busy doing what you do: work, read, eat whatever.
    3. After the flight: Don't get to bed until it is your usual bed time no matter how tired you are. Eat
  • I am willing to be a volunteer. I have jet lag every Monday morning.

    During the week I go to sleep at around 01:00 and wake up at around 07:30. During the weekend this is around 04:00 and 11:30. I am sure many people have such a "jet lag".

    Judging from the replies, I think a lot of people are missing what they're saying in the referenced study: You start fast way *before* you get on the plane. Anyway, the reasoning behind why this works, is that your body thinks: "Hey, there's no food around. I better wake up Mr. Brain there to go find something to eat. And while you're at it, if you have to start hunting saber tooth tigers at night rather than day, then I'll reset your body clock so you sleep and wake at a different time."
  • A period of fasting with no food at all for about 16 hours

    Thank goodness we don't need to forgo the DRINKS (they help get over time zones too, you know).

    Apparently in haste to make jokes about bad airplane food, most have missed the point that the article refers to fasting BEFORE the flight. The Reuters headline writer also missed that fact.

    The idea is to start pushing your food cycle toward the target before you fly so your body is more receptive to the time change.

    In fact, if you're taking the typical ATL-ICN-HKG route some airplane dining is going to be pretty important. You'll arrive in Hong Kong around 10 p.m. Your elapsed clock time including layover will be nearly 24 hours, and if you manage your eating and sleeping during that time you'll actually be in pretty good shape the morning after your arrival. (Hint: Sleep as much as possible between ATL and mid-Pacific, and only after that should you turn on the entertainment system.)

    Another study suggests [bbc.co.uk] that Viagra might help with jet lag, but it might create unrelated issues that you might have trouble explaining.

      And if you had even bothered to read your own article, you'd know that it works even in low doses, small enough not to cause any "unrelated issues."

      Exactly. The procedure suggested by the researchers is:

      1. Start with the day you will arrive in your final time zone.
      2. Count back 16 hours from your normal breakfast time on that day, and stop eating from that point.
      3. At your normal breakfast time on the final day, eat a substantial, nutritious, meal

      Note that this means you may have to eat your breakfast on a plane or in an airport, and it may not be your normal breakfast time in the local timezone when you eat breakfast. You are supposed to eat substantial real food, not coffee and a pastry, so you may have to expend some effort and foresight to ensure that such food is available when you are supposed to eat it.
  • before the flight have always worked for me.
  • 16 hours before the flight? 16 hours before you land? When do you start eating again?
  • ...fasting cures fattiness.
  • I'd rather be jet lagged, than feeling starved.

    Heading east from Hawaii to go back home to Toronto (+6), I just took 6 mg of melatonin at 6 PM HT / 12 AM EDT when I got on the the flight. By 7 PM HT / 1 AM EDT, I was sound asleep, and I woke up around 2 AM HT / 8 AM EDT, fully back on my regular Toronto routine with no detriments.

    I don't know if this would work well with more dramatic time shifts, like Asia - North America, but melatonin in general has been a sanity saver for me. There are days where I take a four hour nap and fear that I'll never sleep at night. Pop a melatonin an hour before I want to go to bed, and I sleep a completely normal night's sleep.

    No uncomfortable fasting required.
  • I doubt it is just me, but after a long plane journey, the last thing I would want to do is to ignore my bodily functions and starve myself! Being cramped in a plane for 7+ hours, I would want to relax and do what I want, i'm on holiday. Or vice versa, I am now home after my holiday, and I am not going to greet myself back with a starving stomach. I mean, yes, it may be a discovery. Now we know, but is it really useful? In my opinion: No
  • I've been (indirectly) involved with transporting super yachts. Generally there's not much sleep to be had while shortstaffing a 50 metre yacht across an ocean. The crew eat to stay awake. I'm not sure the theory behind it, but apparently it works.

    Another way of fighting jetlag is to fly a lot. It's been years since I suffered jetlag, I just got back from Japan, didn't feel it either way, I go to Europe a lot and I went to college in Hawaii and would fly to Italy for holidays. Oh yeah, I eat a lot so maybe that's it! Airlines need to start feeding people more and more often on their flights.
  • Many people may not realize that Fasting actually mean limiting diet to 1 or 2 things.... ie water and cooked brown rice. Somewhere along the line somebelly did not know this and impoverished the language (thank you Terrance;!) to infer eating NOTHING aka "starvation." This is NOT the same thing - and can be dangerous!
  • This looks like it might be related to research (PDF) [antijetlagdiet.com] done a few years back by the Argonne National Laboratory on diet and jet lag. There's a summary of their diet here [netlib.org]. It's more complex than just fasting. I've used it travelling to Israel, Russia and Burma, and it's worked well for me.
