To make clear, it is not a switch that I'm like this while fasting and then when I eat I go back to normal. I'm talking about being in a state where I've been consistently doing anywhere from 16:8 to 23:1 for a long while. DO you take salt when you fast? If I don't take plenty of salt and water when fasting it doesn't work.

[@Lance54689]

@@andrewolivetreemixing Salt keeps me from feeling hungry. When fasting the body tends to flush water so it also flushes electrolytes. What often felt like hunger was actually low electrolytes. Take some salt and I'm comfortable again. I take less salt now that I did at first(three years ago). I'm assuming the body adapts to fasting and holds on to more sodium.

[@dblockbass]

Fasting has many dietary and cognitive benefits we dont completely understand yet. Its something that I inadvertently adopted when I was a dog runner in NYC out of necessity. I literally could not afford to eat 3 meals a day. But I discovered when I was eating once a day my productivity went through the roof. My physical prowess and my focus and concentration was better than at any other point in my life. (I wrote the manuscript for two books during this time) Keep in mind this was in conjunctuon with a moderate amount of exercise (running at least 5 miles/day). It is a practice in will power/discipline, instincual hardwiring rewiring, and dietary/physiological metamorphosis. He is dead on. It varies from person to person. I still practice it. I can not eat 3 meals a day. That is way excessive for me. The ketone diet my friend is remarkable.

[@chuckboy9372]

My theory is that is not just about the changes in your body, it's the changes in your mind. Modern food is a satiating drug. It satisfies you and boosts certain neurochemicals so that you feel like you've achieved/accomplished something good. But you haven't. You've just gone to McDonald's and ordered a big Mac. Food is used as a coping mechanism today and keeps our mental state in a cycle of eating, wanting more food, and eating more. We've been trained like dogs with treats. When I cut out junk food, sugary food, and snacking, I notice that my brain returns to the dull thud of reality. It's as if I'm waking up from a light nap. I become more likely to get up and do things. I become more aware. My theory is this. Junk food boosts dopamine. Extreme levels of dopamine desensitizes us from dopamine. Since dopamine is what actually drives us to perform tasks and search out rewards, we start to have no drive to do anything in life because of our dopamine insensitivity. We just can't use the dopamine we already have. After years of having your brain trained to exist like this, your brain will have physically changed and it will be exceedingly difficult to change yourself.

As a follow-up to Dr. Huberman's point about how time-restricted feeding impacts weight loss, Dr. Liu, Deying, et al. recently (April 2022) published “Calorie Restriction with or without Time-Restricted Eating in Weight Loss” in the New England journal of medicine. They showed that among obese patients, calorie restriction & 8 hr time restriction eating regiment did not yield additional weight loss as compared with identical daily calorie restriction alone. Happy reading everyone :)

[@ZedP]

Fasting is not only about losing weight, but also about body recomposition. It means that fasting takes more from fat storage than from body proteins, keeping lean mass intact and thus recomposing the body (less fat, more muscles). Add some exercise to it - and the results are very encouraging. Other studies (that can be found in PubMed database) also showed that fasting is not more effective than calorie restriction, but only in the sense of weight losing.

[@Guy-ns1hk]

I love how credit for fasting is given to two or three contemporary scientists, when our ancestors world-wide have left clear instructions to fast, embedded in religious protocols and meditative practices- The benefits of fasting have been recognized and revered for millennia.

[@QualeQualeson]

No need to take this to extremes, as you get all the benefits and none of the downsides when you do sensible intermittent fasting. 16/8 18/6 or 20/4, depending on individual parameters. Need to lose bodyfat, make the window a little smaller. Otherwise stick to something that keeps your weight stable and also gives your body the regenerative effects of not having to process food all the time. I'm pretty sure this is how nature intends for us to eat. It's simple, it's healthy and (after a few days of mental adjustment) it's not hard to do. Because when the window is closed it's closed and there's no point thinking about it. And when it's open you can eat normal varied food that tastes better too. Indulge every now and then if you get sick of it without feeling like you've failed, and unlike when you stuff your face all the time, even a small snack will feel like an amazing treat that can last you a week or even two. Just reel in the slack the next day and keep trucking for the long haul and you're golden.

[@anonony9081]

Good point on enjoying the treats more . I used to put so much sugar in my coffee and after going low carb the milk alone was enough sweetness for me

I've done probably 15 to 20 5-day fasts in the past 5 years. Also have done 2 or 3 7-day fasts and two 10-day fasts. The energy and clarity happens for me as well. My most recent 10-day fast was maybe 5 months or so ago. Initially I planned on doing only a 5-day, but I felt quite good on that day so figured one more day. Then the next day felt great, so pushed to 7 days. Each day I was feeling great. I really didn't understand it but recall telling my wife and mother how energized and how much clarity I had even up until day 10. No lethargy or energy drain, it was quite the opposite. Have never gone beyond day 10.

[@ethereal369]

Fasting creates a natural state of detoxification in which the body uses the energy gained from not digesting food to get rid of the toxins, damaged cellular materials & waste products stored in the body. Gallstones are made up of bile acids. You can help prevent them by occasionally ingesting fresh squeezed lemon juice & olive oil & lots of water It will minimally affect your fasting but powerfully aid in cleansing, detoxing & preventing systemic inflammation, as well as preventing the gallstones & kidney stones that can be an issue for some when fasting.

[@jean-philipperoy8163]

Metabolic water refers to water produced in the body as a byproduct of metabolic processes, particularly the oxidation of macronutrients like carbohydrates and fats. When carbohydrates are oxidized, they release water molecules, and fats can produce even more metabolic water because they contain more hydrogen atoms per gram compared to carbohydrates. This process can help sustain hydration levels, especially in situations where water intake is limited. It's possible that the increase in glucose levels observed during sauna sessions could be due to the body's response to heat stress. When exposed to high temperatures, the body may release stress hormones like cortisol and adrenaline, which can raise blood sugar levels as part of the fight-or-flight response. Additionally, dehydration from sweating could concentrate glucose in the blood, leading to higher readings. However, more research is needed to fully understand the relationship between sauna use and blood glucose levels.

I greatly improved my eyesight this way. And it was not and is not an easy path, but oh so worth it. I was in a constant up and down mood/energy level. I rested in my hammock outside looking at birds, butterflies, dragonflies, clouds, tree branches, leaves, etc. in nature.

(but maybe it's not a bad idea to get the electrolytes, but I'd much rather do "Trace Minerals" that has the salt removed. but since I live in the Philippines for many years, the coconut juice provides the electrolytes and some energy but still allows the cleansing I'm seeking like removing "gunk" off my eyes.)

I agree with some of this. I’ve done a fair amount of fasting both intermittent and longer. Focus and energy do go up. However I disagree that eating complex carbs makes you hazy or unfocused. Try going plant based. Energy and focus are similar or better than fasting basically all the time. And sleep is better. At least for me, meat and dairy are what makes me tired and mentally foggy. But I still eat meat and dairy occasionally because it’s tasty 😀

[@Ruktiet]

It’s highly unlikely that meat causes mental problems for you.

I was having health issues and did a 21 day water fast and the symptoms went away.

[@rachelcoleman4693]

Can I ask what health issues you had?

[@johnm2579]

@ Well I was having frequent bouts with ankle pain to the point I could not walk without server pain. Would last for weeks. The doctor said there was nothing he could do. This went on for years with the pain coming and going with no clue what was happening or causing it. I had known about fasting but never had any reason to try one. One day I woke up to the ankle starting to get the pain again so I started the fast that day. Consequently the pain never got any worse and about the third day was gone. After 21 days I felt great lots of energy and was thinking I could go longer but I decided to break the fasting. Well it’s been at least 10 years and I have never had a recurrent event. Guess the doctor was wrong. Also an added benefit was I was suffering from symptoms of an in large prostrate was needing to irritate frequently those symptoms also went away and became normal. I had symptoms of candida over growth belching and always feeling bloated. And a rash do to the fungus Canida in my blood.Symptoms gone after fast. Never to return. There is no telling what is lurking in us. Usually when symptoms show up you’re pretty sick. I had a friend that got cancer on his arm a the doctor wanted to start treatment but he declined and went on a fast. All signs of the cancer were gone in his third week of the fast. The doctors could not believe there were no signs of the cancer at his next visit to Dr. A fast will let the body return to Homeostasis. Disease and funguses cannot survive in a body fasting. Cancer is a fungus fed by sugar so when you fast you starve the cancer.

I'm fairly new to nutrition and taking care of myself in a serious manner in terms of being mindful when it comes to diet. I have a crazy metabolism so gaining/keeping healthy weight is kind of hard. Plus I am now a regular at the gym because I want to get in better shape and add muscle. Is fasting something I should consider? I don't naturally have a lot of body fat, and I want to make sure I am getting enough calories to help with muscle gain. Am I just eating a shit ton during that eat period? (Disclaimer: my diet is NOT IMMACULATE but its respectable. Little to no processed food. Good variation of fats, carbs, protein, etc.)

[@jumpkut]

Track your calories. Get enough protein. Fasting can help in as far as it limits the time you have to eat aka get calories in. Fat loss is calories in calories out at the end of the day. Godspeed

[@sje106]

I’ve started fasting this week. I am trying to eat once a day. And not to go too mad when eating. Just a decent piece of meat and a handful of veg.

[@MOAB-UT]

In the words of the caveman. Fasting GOOD. 16:8 is easy to do. 2MAD. Kind of a no brainer. Not daily though. I do maybe 2x a week. If I don't feel well or have any digestive upset, I use that as an excuse to do a 36 hour fast so I will skip an entire day- nothing but water. It works great.

[@joshb2885]

Long fasts are wonderful. Days 1-2 you feel like you could eat a small cow. Days 3 you feel like you got hit by a truck. Days 4-5…you feel like you can fly!

[@vitaly6312]

I did a 28 day fast and it was phenomenal. I wish that I gave myself a task to complete during that month. I’ve done 7 and 14 day as well. Honestly if you’re doing 72 you may as well do 5-7 days since hunger drops off after day 3 or so. I’m planning on doing weeklong fasts at least quarterly, IF daily, and at least a 10-20 day fast once annually.

[@ErickOberholtzer]

I would like to do things like this as well. What resources do you know of to do it safely?

[@liambrereton2641]

I used to do long multiday fasts and piano playing went way up. I was in an otherwise low dopamine state with slow fingers but the fast freed them up and allowed me to execute the music I already knew. Surpised how it all came back to me during the fast!

[@glenneric1]

I fasted for 3 days, felt great, ate a hearty lunch on the fourth day, got nauseous and light headed and threw it all up. Be careful.

[@Stormie33]

You definitely have to ease into eating again after a fast of that length. "Ate a hearty lunch" should've been replaced with "nibbled on a piece of lettuce for an hour".

Either intermittant fast or just take a couple days off kickboxing when you do it, time it so its synced with rest days anyway to minimise missed kickboxing days

I never had these benefits from a low carb high animal product diet. That diet makes me wanna sleep bug time. I did a whole food plant based diet and my energy was the best ever. I started running. I snored slightly it went away it was like inflammation went down in my body in general. Aside from the energy I felt the best mental acuity of my life so I can't concurr with the claims made here from my experience

[@RehmanKhan930]

When fasting I would get headaches about 16 hours in. Any suggestions?

[@XyzTorres]

Might be due to no Sugar. Try to reduce sugar consumption for a few days before a fast. I’m no expert bro so just take that with a pinch of salt but it’s just my initial thought

[@therealdonaldtrump1646]

Go check out the SnakeDiet dude. He'll break that stuff down for you.

[@neinbruderja7519]

To me having the same issue was due to coffeine dependency. When I drink coffee at work every day and add a 24 water fast on the weekend, I tend to get the headaches. If I drink coffee during the fast, I don't. If I eat regularly for a day without coffee before the fast, I also don't get the headaches. Might be different from you though.

Looks like caffeine addiction or lack of sleep.

[@tristanschmidt_sw]

Eat like the Romans, high carb meals, breakfast, lunch and dinner. You will perform your best and feel your best - someone who trains around 3 hours a day, with 25 000 average steps - i'm also sub 8% bodyfat and so full of energy I have to contain it via forcing myself to meditate. Let that mind go and let the body be free. Eat what you desire - we all know this is high carbs

I'd rather have the health and longevity I desire than to eat what I desire.

It depends on the individual on the mental side but actual benefits aren't questionable they've been proven scientifically

[@akonramrim5245]

Same what muslims do for a whole month in ramadhan, for 30 days sunrise to sunset nothing is eaten and post that sunset to sunrise you are allowed to eat. Complete one month you main a strict timetable and also on the other hand for your brains there is no music no entertainment but only religious activities. One month you are on a different journey of life every year in Islam.

[@ws7001]

That fasting period is too short for autophagy to begin and therefore results in limited benefits. 18-20 hours seems minimum period for these benefits, 3-4 days even better. But at least it gives your liver and pancreas a break.

[@believer8754]

Ofcourse Muslims doing fasting 30 days every year about 16 hours every day

[@youngsuit]

the problem i notice is that if i fast for a long time, it's hard to fall asleep. so i can't imagine being able to sleep while on a 24 hour fast.
