  • Experimenting with longer fasts...

    I usually do a daily fast of 20 - 24 hours (and eating once a day), but this is now pretty easy for me. As of late, I've been adding in longer fasts, 48 or more and feeling great. Better than EVER I would say!

    For me, when I embark on a longer fast, I tend to eat a bit more in the meal before the fast than I would if I were eating daily. Then, I do seem to convert a little bit of that into fat (yeah, this effects me the first day of the fast). By the start of day two though, I'm usually well into ketosis and that extra fat I put on from that meal is coming right off. I then continue my fast until my energy llevels start to wan a bit.

    What I am finding though, is... I have MORE energy on the fasts than I do when I eat daily. I'm almost PREFERING this style of eating now. I'm starting to realize that this is almost no longer a "challenge" for me. I'm leaning out, but so far, not losing (or at least not noticabley so) muscle mass, my workouts don't seem to have suffered, my energy levels are UP, my libido has actually increased...

    All I can say is... I must be doing SOMETHING right.

    So, my question to you folks is this... What do you think of this? Could you do it? WOULD you do it? Do you think that it's healthy because I feel great, or would you still worry about anything as a result of my new habits?

    I'll assuage your fears by saying that the fasting hasn't made me want to resort to unhealthy "cheat" meals because of any sort of ravenous hunger or lack of motivation to cook a healthy meal. Whever I break my fast I still do so in a healthy, high fat stick to the ribs meal of meat and veggies. Dr. Mark would be proud!

The metal in my head clangs and clings as I walk - freaks my balance out. So the natural thought is just clogged up. Totally clogged up. So we need to unplug these dams, and make the the natural flow... It sort of freaks me out. We need to unplug the dams. You cannot stop the natural flow of thought with a cling and a clang..."

    These days, I stick to the leangains approach daily and I haven't done a longer fast in ages. I know that I can still go for forty to forty eight hours anytime I need to though. Other than needing protein, I don't think there is anything wrong with fasts that length. That said, I'd never go longer than forty eight hours intentionally.

      I just go until I'm hungry which, if I eat the slightly larger meal, seems to be 48 - 50 hours. So I'm about where you are. I've gone longer a handful of times, so I know I can do it, but as Mark says, "when!"

        Have a look at this thread. A bunch of us did a four day one recently and there is a lot of good info referenced in there.

          I think you misunderstand. I'm not talking about a four day fast once in a while. I'm talking about 48 hour fasts almost twice a week. In the long run, a four day fast just to see "if you can do it," is one thing, especially if you don't plan on doing it regularly. I've basically started doing my fasts on a regular basis now.

            I'm in the same place as you regarding daily fasts.

            Assuming I'm not interested in weight loss, what are the benefits of the 40-48 hour fast over the 20 hr fast?
            Disclaimer: I eat 'meat and vegetables' ala Primal, although I don't agree with the carb curve. I like Perfect Health Diet and WAPF Lactofermentation a lot.

              You definitely get a more even energy level, and you don;t always have to be thinking about your next meal so you can spend that time doing other things. I'm more productive like I've never been!

              And I'm not really losing weight in terms of dropping pounds either. I'm "leaning out" is the best way to put it. Losing body fat more than weight.

                That thread started off being about that one "see if you can" four day event but from there it evolved into a very interesting discussion of all different lengths and frequencies of fasting with some really good resource material brought in if you are interested. The consensus reached seems to have been the very one you are talking about. 48 hours about once a week.

                  But I'm doing it almost TWICE a week now, not just once. So, consensus in that thread would be that twice is too much?

                    You don't need to rolleyes at me. If you will note I went back and edited what I said to be "about once a week". Some people were saying once some two, but, hey , read the thread or not. There's some good info there if you don't already think you know everything.

                      I'll roll my eyes at you if I want to young lady!

                      I never claimed to be the perfect source of knowledge on all things fasting. I wouldn't have asked if I was.

                      I did look at that thread. I haven't the patience to read every single one of those studies. Sometimes it's nice to have that information encapsulated for you. And I think I'm going beyond the general consensus. They were saying one 48-hour fast a week is optimal, two is pushing it. Only seemed a couple said there should be no issue.

                      Just wondering what the rest of you all though, I mean... I feel great!

                        Well you should try actually doing the two 48's every week and report back.

                        I feel like maybe there's a natural tipping point once you start skipping more meals than you eat (I mean on this plan, you would eat on 3 days out of the week, yeah?). Someone here once posted that they eat only two days out of the week.

                        I always experience a bit of a honeymoon period when I get into a good fasting routine. I'm good eating one meal for a few days, then I like to eat a little earlier. Sometimes it ends up being breakfast and lunch, but no dinner. So it's a little erratic, but that's one way to do it of course.

                        I'd be interested to know if you end up finding it sustainable, doing the two 48s, once you've done it regularly for a month or so.

                          I would think it would depend on how much extra body fat you have around to draw on for the lean days. If you have quite a bit then I don't see any problem with twice a week but, if you are at or close to your goal weight, once a week might be better.

                          The two sources that resonated with me most were the Eat Stop Eat book and the posts here and on his blog of pklopp. Both seemed to point toward the 40-48 hour range as the time when the benefits of the fast had mostly been gotten and after that there were diminishing marginal returns for additional days. I got the impression though that Brad Pilon was looking at fasting primarily as a tool toward calorie restriction. I am more interested in the autophagy and mitochondrial regeneration aspects (given that I have a history of seizures and am trying to control them on less medication.)

                            The way you prevent the caloric deficit is to eat a much larger meal than normal. You'll slip into ketosis on the fast almost for sure, so any fat you put on from the extra large meal should be used efficiently as energy and things will balance out. In theory at least.

                              Personally I wouldn't mind the caloric deficit : )
                              I just mean, with only 3 days a week, every week, it's like "intermittent eating." But I have no reason to think that would be a bad thing other than my gut response. If it's what comes naturally to you, go baby go.
