Study: Time-Restricted Eating Improves Cardiovascular Health for Firefighters
- nico 4y ago> “It’s not a pill, but a healthy habit that can significantly reduce these three risks of disease without any adverse side effects.” This is probably the case for a lot of health issues. But we always want a pill that will fix the issues while allowing us not to change our habits.
- colechristensen 4y agoSauna seems pretty close, it’s just sitting somewhere hot on a regular basis and is quite pleasant. Saw a study recently that showed broad, dose dependent health effects. Personally it really seems to help when I’m overloaded with stress, in a direct immediate way.
- xwdv 4y agoIt screws up your semen.
- colechristensen 4y agoWhich reverses when you stop.
- invalidname 4y agoGreat male contraceptive ;-)
- getcrunk 4y agoOr fixes it depending on your life goals
- spoonjim 4y agoMost men have only about a 10-year period when they care about their semen quality, you can use the sauna the other 50 years.
- irrational 4y agoOther 50 years? What happened to the other 40 years?
- spoonjim 4y agoI assume ~80 year lifespan and that you start going to the sauna as an adult.
- eru 4y agoWhy would you only go to the sauna as an adult? In any case, how long does sauna's supposed deleterious effect last? Probably not more than a few days?
- krageon 4y agoI would be very surprised if it was above one day.
- colechristensen 4y agoFor sperm metrics to return to normal, a few months.
- mrmuagi 4y agoWhat about testosterone?
- tsol 4y agoDon't sauna in the few days before you plan to conceive. Bikes, among other things, can also screw up your semen. It's not that uncommon, and it's only temporary
- vvpan 4y agoDo you think you can find that study?

- TedDoesntTalk 4y ago> quite pleasant. I use sauna 20 minutes per day about 5 times per week (helps to have a small one in the home. Don’t get infrared if you get one). I would not call it pleasant. If done correctly, your heart rate is elevated (130-135 bpm for me), and you are sweating profusely.
- eru 4y agoWell, to get the full benefit you also want the ice bath afterwards. Sauna is fun, but it's not a panacea. It can't replace exercise, for example.
- m463 4y agoI remember reading that the reason that many doctors prescribe pills over a lifestyle change is that it is significantly easier to gain compliance. I can imagine it's kind of like being a parent or manager. After advising perfect behavior and rarely getting it, you give up and settle for easy, less perfect but achievable advice.
- dominotw 4y ago> doctors prescribe pills over a lifestyle change does doctors prescribing lifestyle change have any noticeable effects though. I assume everyone already knows they need to 'eat better and exercise'. I am not convinced that doctor telling them this will finally make it sink in for anyone. Also, most doctors have layman level understanding of nutrition and excercise and many of them are not in best shape themselves.
- stevenwoo 4y agoLimiting eating to ten hours might be a stretch for some people's lives but it's a simple plan that is easy to understand. TLDR - the study compared a ten hour window versus a fourteen hour window control group (and fasting in between).
- georgeburdell 4y agoApplies to late shift working, which is already well-known as a health risk
- neuroma 4y agoWhat is late shift working? Is it different to night shift work?
- georgeburdell 4y agoThe article just calls it “shift work” and define it as working 2 or more hours between 10pm and 5am
- jansan 4y agoLate shift usually starts around noon or early afternoon, night shift starts in the evening.
- clumsysmurf 4y agoIts not clear to me, when the 10 hour feeding window was allowed. Was this still at night, or some part of the day where the sun was up?
- hericium 4y agoThere were 10 and 14 hours long windows. It's ok to fast during the day. I often only eat in late afternoons and early evenings[1]. [1] https://news.ycombinator.com/item?id=32864708 https://news.ycombinator.com/item?id=32864708
- nikkwong 4y agoNot sure how this study was designed; but it's been replicated probably dozens or hundreds of times that circadian-based eating schedules confer the best metabolic benefits. That is, the earlier the eating, the better the metabolic benefit. Although I have seen some data that suggests you should wait one hour before consuming your first meal (as you should wait for the cortisol spike from waking to taper).
- mrslave 4y agoI am always unsure how this applies to someone with an irregular exercise schedule. If, when fasting (intermittent) my exercise is primarily cardio then I will continue fasting. However if it is resistance training, does getting some protein into my system as soon as possible take priority over fasting? Or is this less important than the immediate-protein-shake crowd suggests? Should I try to pull the window forward if exercising early?
- jb_gericke 4y agoThe 'anabolic window' has largely been disproven. Depending on your goals though, from a resistance training perspective you typically need to be in a caloric surplus (although not an excessive one) to put on muscle.
- nikkwong 4y agoI'll assume that your goal when drinking a protein shake/gaining muscle is to gain muscle. It's generally believed that a state of anabolism is generally viewed as being antagonistic to the body; too much protein/growth is taxing. Yet, having muscle is important for aging, and also acts as a glucose sink thereby improving metabolism. A balance has to be achieved. > Or is this less important than the immediate-protein-shake crowd suggests? From what I've read, this may be not as important as originally thought. Overall, I believe the schedule that most holistically supports metabolism would be to exercise early and also eat early in the day. This would thereby keep the taxing metabolic activities aligned to your circadian clock, which expects a lot of early day stressors and fewer as the day progresses. This may be specifically true for protein which is especially metabolically taxing, so eating it early in the day is probably the time when it creates the most benefit at lowest risk. Of course, people have to do what works for their schedules and lifestyles.
- TedDoesntTalk 4y ago> exercise early and also eat early in the day This is slightly contrary to what I’ve learned from Rhonda Patrick. Exercise in the morning, sure, but while still fasting from overnight (black coffee or plain tea ok… does not break the fast). Eat after exercise so that your fast lasts longer. Also, cardio exercise blunts the hunger feeling in many people.

- dtjb 4y agoWhat purpose does that last sentence serve?
- 876978095789789 4y agoShould I be more tactful towards dangerous health misinformation being spread here?
- dtjb 4y agoIt actively thwarts that goal.
- mancerayder 4y agoI feel more awake when fasting. I feel sluggish and hungry if I eat breakfast. It's not ridiculous to skip breakfast. How is that idiotic ? I have top health markers for my age and do a variety of different types of physical sports. I think the old adage (still popular among powerlifters and bodybuilders) to eat every 3-4 hours to be completely stupid. We never evolved like that, it's a luxury modernity that this is even an option.
- 876978095789789 4y ago> We never evolved like that, it's a luxury modernity that this is even an option. That's the brainletism I was referring to. You could have easily verified your assumption by looking at remaining hunter-gather populations, who serve as a good proxy for you ancestors, and had you done that, you would have discovered that--surprise, surprise--they don't fast: youtu.be/Ci70YYaVHeQ?t=2807
- mancerayder 4y ago
- cnagesh 4y agoIf I understand this correctly, the experiment is suggesting to have a gap of 10hr window between any two meals ?
- stubish 4y agoNo, all your eating happens in that 10 hour window. You fast for at least 14 hours per day. Easy enough if you eat an early dinner and don't snack after.
- k__ 4y agoIs the position of that window relevant? So, I sleep 9h, which means, I'm awake 15h. If I don't eat 2,5h before and after sleeping, would this be enough?
- deleted 4y ago[deleted]
- resoluteteeth 4y ago> Is the position of that window relevant? Who knows! This seems like one of the things that makes it hard to test intermittent fasting: there are a bunch of variables other than just the length of the window.
- stubish 4y ago> If I don't eat 2,5h before and after sleeping, would this be enough? Some researchers think so, yes. I don't think anyone knows what is optimal. Research is ongoing.
- swyx 4y agoso lunch AND dinner or just early dinner? always feel like these hourly windows are underspecified since you can cram a ton of food in that time

- nonrandomstring 4y agoReally enjoying IF and it's had enormous benefits for me. The doc basically said my latest bloods are outstanding, way, way down from the serious telling-off I got 6 months ago. I'm not using someone else's schedule, just listening to my body and pushing boundaries as hard as my fitness will allow. But there are mental "downsides" to reckon with. It's not grumpiness, but rather a "predatory" state. Not quite aggression - a little more of the warrior mode circuits seems switched on. Plus general heightened emotion and general willingness to speak the truth, fight/defend others, take risks.... Working out how to deal with that and integrate it positively is my present challenge. Anyone else getting that?
- AnthonBerg 4y agoSeen it in people. It's a quite beautiful side.
- AnthonBerg 4y agoDue to a downvote I wish to reaffirm my position: I do see a somewhat warrior-mode-like side of people who are fasting. And I do find it to be beautiful. It’s not bad company.
- cassianoleal 4y agoBeen doing IF on-and-off for maybe 5 or 6 years. I get the same way. Since you already called this "warrior mode", I'd recommend reading the warrior literature for tools and techniques to help deal with this in a positive way. If you're new to it, The Way of the Peaceful Warrior by Dan Millman is a great introduction and there should be enough references on it to start digging deeper. There is a movie for the book as well but I don't recommend it.
- nonrandomstring 4y agoThis looks like a perfect antidote to my not-peaceful warrior experiences [1]. Thank you. [1] https://www.goodreads.com/book/show/2255.Way_of_the_Peaceful_Warrior https://www.goodreads.com/book/show/2255.Way_of_the_Peaceful...
- dominotw 4y agoI've been trying to do this for years but I like my coffee with cream and sugar. I've tried various sugar/cream alternatives over the years but nothing really stuck. With coffee+lite cream + sugar I fast about 15 hrs a day. Am I getting any benefits at all?
- nice_scott 4y agoI am the same way, except I just cream. Every time I have come across a discussion on this topic of having cream in your coffee while trying IF, the anecdata consensus is that any calories at all break your fast, so you are no longer fasting if you consume a small amount of cream/sugar. Having said that, I still do 18/6 IF with cream in my coffee and in my personal experience I still feel great and have had many positive benefits from continuing IF.
- ramoz 4y agoIgnore the bro science. Keep your cream, though you should probably drop the sugar. I limit my coffee creamers to about 25-100 calories depending on number of cups pre-meal. I’m in better shape than most hardcore IF practitioners. CICO.
- garrickvanburen 4y agoTo me, a 10-hr window (eg 8am-6pm) doesn’t seem restrictive or even mildly inconvenient (definitely not enough to classify as IF), so maybe the insight here is that people regularly eat across all their waking hours - and not doing that is better.
- strikelaserclaw 4y agoIt is just how devolved our modern eating habits are, we are constantly snacking or eating garbage which makes us hungry soon after. Three solid meals a day, cooked at home with unprocessed food ought to be good enough to live a healthy life but for the people who go on all sorts of diets, food has long become an emotional thing so they need restrictive frameworks in place to help them not eat so much/eat junk food. I bet our ancestor never thought this hard about what to eat and when to eat.
