100 Hour Fast: The Full Transcription

Observations of a Hundred Hour Fast

Observations of a hundred hour fast from my experience. My name is Loren Weisman, I’m a brand communications and optics strategist. And I took, I wouldn’t call it a challenge, but more so just an attempt at the longest fast I’d ever done.

I did a number of 24s, a series of 48s. Every few months I would do a 72. But this past week I felt pushed to try to do what originally started as a four day and then was, okay, if that’s 96 hours, make it 100.

I did this. Now, prior to saying this, I’m not any kind of health expert, I’m not giving any kind of advice. I’m not saying do this or don’t do this. I’m simply sharing my experience, what impacted me and how it impacted me.

Fasting Videos That Claim What It Will Do for You

And one of the issues I have with a lot of people that put up fasting videos online is they, they share linear experiences that they’ve had for themselves and then begin to go out there and claim, this is what it will do for you, this is what it’s going to, this is how it’s going to affect you. This is how it’s going to impact you.

Yes, there are certain things that are absolute. There’s an element of ketosis, there’s an element of autophagy, there’s an element of hunger. There’s a lot of different things that happen. But all of us, we come from different times, different bodies, different ages, different experiences, different diets.

Seven Days in the Bible and Redefined Fasts

So I’m sharing my experience more on the whole of, if you’re considering doing something like this, here’s one option and the path that I experienced, yours could be absolutely different. I was looking back in the Bible and I was reading and this was during the fast about, you know, and then David fasted seven days.

I can’t do that seven day thing. And I looked at some of the people that are saying, oh, I’m doing seven days and I’m doing these and I’m doing these kind of fasts. But then they talk about, well, they’re drinking electrolytes or they’re drinking this or they’re eating that.

But they still redefined a fast. To me, the fast that I did was a water fast. All I had was water, no salt, no electrolytes, no teas, no any kind of sport drink, nothing like that.

Health Issues and Planning Around a Schedule

It was purely water and nothing else. Also, as I was doing this fast, I’m having some health issues. So I was, I’m not up and around all that much at the moment. So it made it a little bit easier.

I mean, if I was trying to think how I would do a four day fast if I was in fifth gear and in a normal schedule. And I thought, okay, maybe I’d start that on a Thursday or a Wednesday night and take it through Sunday.

Driving During a Fast

Because the first two days of the fast I could operate. I could, I mean, there was a focus overall. Come day three, I was going to run an errand and I just for me, I felt like getting in a car was not a good idea.

And with some people and some bodies and some people that are a little bit smaller, if you’re fasting, maybe driving as a whole, any part of that fast is not such a good idea. Day one to me was normal.

Day One and Day Two

Oftentimes I do 18, 6 or 24 intermittent fasting. So it really was in a sense just popping four more hours on it was not a big thing. It felt like the normal fasting. There’s an aspect that feels a little cleansing, there’s an aspect that feels a little opening for me.

Day two, a little bit more of feeling the impact, couple moments of feeling just a little bit dizzy. But also what I’ve noticed is in the 48 hour period, certain elements where you feel a little off physically, they can come a little stronger strategically, creatively, cognitively.

Day Three Surprised Me

I felt a little bit more on my game mentally and for some of the work that I was doing. Day three surprised me. I normally do not pass the 72 and in the past when I’ve done that, I’m in much more of a resting thing.

But day three was a working day for me. And as I was working, I dealt with a really just awful narcissistic attack from someone. They were throwing, you know, just insult on insult. They were being immensely difficult, they were being really challenging.

Responding Calmly in a Fasted State

And as I’ve worked to better myself and be calm and react subjectively and not eye for an eye, I felt a little bit stronger in that fast state. I felt that I could respond.

I felt not only the jabs didn’t hit, but just the cognitive element of going, no, I know this isn’t true. And right now, to return an insult on insult or to prove this person wrong or even to showcase the evidence that this person is wrong, it’s not going to serve me, it’s not going to serve them.

So not saying I wouldn’t have reacted in a strong way, not being on the fast, but I felt stronger on the fast. I also, if you know, weight is not a thing to me when it comes to these fasts it never has been.

Fasting for Health and Faith

The fasting for me is health. And that fasting for me is faith. There’s a faithful element as I believe we’re told to fast shows up there in the Bible. So I was fasting and I.

And as I was fasting, I was praying on some certain things that were that or that were that are impacting my life. And I was asking for wisdom. I was asking for discernment, understanding, knowledge, clarity.

I was consulting in a way where I said, okay, tell me this, help me to hear this. And sometimes I feel for me in a fasted state that clarity of what’s heard is a little bit more.

It’s a little bit more tuned in, it’s a little bit clearer. And certain things that I was asking about I feel I got answers to. So from the faith side of the fast, I felt some clarity.

Sleep and Vivid Dreams

And I was re asking the questions a couple times over and over again through even just the hardest times, and they came through. The sleep was different. You know, the first night was nothing.

The second night, the. The dreams were a little bit more vivid. The third night, it was a very vivid dream and you know, just that much more colorful, that much more alive. I don’t remember a lot of my dreams.

This one I remember from start to finish. Coming into the last day, I’d never gone four days, much less the extra four hours to hit the hundred mark. I had originally set my schedule to do some things in the morning and then cut off.

The Last Day and a Boost of Energy

I figured, I’ll watch some tv, I’ll read a little bit, I’ll pray, I’ll just kind of come in, come in on the end here. Slowly. Didn’t feel the need to. I felt another boost of energy.

Even in a little bit of exhaustion. I felt creatively energetic. I worked on a couple recordings, I worked on some things I needed to write. I worked on a couple strategy elements.

I even took a couple calls that I wasn’t planning on taking till the beginning of the week. It ended up being as strong I was coming toward the end. And then it was funny because in those last couple hours I was at that point at around 94, 95.

I was starting to get hungry and I wanted to eat. And then it was 98 and 99 where I thought, okay, I’m closing this out at five. Would it be better to just take a shower, chill out and maybe take this thing a little bit longer till the morning?

Breaking the Fast

Once, once 5, 27 came along, my end point. I. I felt it was not going to go any further than This I had, I had a little bit of chicken noodle soup, I had a banana with a little bit of peanut butter on a piece of sourdough with a little honey on it.

I had some fruit and I had a prebiotic drink that was already in the refrigerator and all light and small amounts just to not upset the stomach. My stomach was a little bit upset, but it was a good night of sleeping.

I woke up this morning and had a smaller healthy breakfast and feel just dialed in and almost refreshed in some of the things that’s happening to me physically which have been a great challenge. There’s a pain reduction that was happening during the fast and while pain has kind of gone up and down and up and down, it’s at a lower level right now.

A Different Scent

The last couple things I noticed that were strange in the 100 hour fast was it was almost like emitting this different scent off. I’m, I’m very smell sensitive and I’m not saying it’s like a stench.

And I was showering and I was doing whatever, you know, to be healthy. I wasn’t one doing one of those extreme fasts where I wasn’t even brushing my teeth. But I feel like my overall scent has been around.

Day three, it just altered a bit. It was just a little bit different. Nothing bad, nothing offensive, just a touch different. And I’ve noticed it even this morning.

Becoming More Aware of Sounds

The other thing too and that changed was sound. I became about day three I became much more aware of sounds even to the point that certain noises were, they were enhanced and certain noises were just annoying.

Like I was turning certain things down or I’d hear a certain noise that would never bother me before it became annoying. And then, you know, this morning waking up and hearing some of those similar sounds, nothing, it’s gone.

My Experience, Not a Recommendation

I don’t have that enhanced or whatever it is hearing. So again in wrapping this up and not trying to ramble on for 10 minutes and some. But this was my experience. I’m six two, I’m 240, probably a few pounds less right now because of that fast.

I’m having certain health issues right now where I’ve having a couple surgeries, I’m having, you know, all of these things play in. I’m also a man of faith that plays into the way that I fast and how I fast and the experience in there.

Your experience may be different, your faith may be different, your body may be different if you’re considering fasting. And I’m not putting any kind of recommendation on it. Look to how people experience, but plan the experience for yourself.

Ketosis, Autophagy and Your Own Experience

Yes, there’s a scientific about ketosis and autophagy. Yes, there are proven benefits as a whole, but inside of these proven benefits, they might not always end up proving true to you.

That’s part of the optic of this thing and it’s part of what I do inside of business, that while this is something impactful, while it felt strong for me, while I’m glad I did it and I’ll do it again, and I’m probably going to get on to, even just after getting over this, I’ll get back onto an 18, 6 or a 20, a 20 and a 4. I actually have a.

A Call in the Middle of the Fast

Not to get overly personal, I have a colonoscopy. And at the end of the week, and they were, they were on the phone, they called me doing all the confirmations in the middle of the fast and they’re like, okay, so we, at this point, you can only drink water or you, you can’t drink anything else.

You’ve got to do this. You’re going to, you’re going to be looking at about 24 hours, a little bit more, give or take. Are you going to be able to handle that? You can’t do food.

And I told the lady on 100 hour, 24, 24, 30, no problem. Point. Point being, if you’re looking into this, look at what it is for you and if something feels off, stop. But at the same time, with all the hype that’s out there, with all these people saying you need to, you have to.

Trying New Things Without Being a Sheep

Here’s the latest challenge. If that doesn’t fit for you, don’t follow it. If it doesn’t feel good to you, don’t follow it. Don’t be a sheep, try new things.

But also, if your favorite influencer or your favorite person is saying, this is this and this it’s opinion. The same thing goes back to those days when everything was, it’s this antidepressant or it’s this weight loss drug or it’s this food.

For every time that we were told we can’t eat this, but now you can. This is absolutely awful for you. Oh, no, no, it’s really good for you. These things are subjective.

We where they are proven with a certain group of people. It’s not that way with all people. So as you experience things, whether it be with fasting, with your health, with your fitness, with your business, take the time please to look in to see what’s going to work for you and use the experiences.

Your Experience May Be Different

I mean, if my experience What I’ve gone through is of any help or things that you may compare to or things that you may contrast to great. But my experience will definitely not be your experience.

Or maybe it will be dead on. But the point is, I guess that’s where I’m kind of rolling and I’m sorry that I’ve rambled even further.

Opinion, Experience and AI

The point is, with anything physical business anywhere else, look to what’s out there, what people have experienced, but make sure that as you take it in, you see it, even if they’re claiming it as fact, that it is their opinion and their experience and your opinion and your experience may be different. And that even goes into AI.

Oh, AI told me this. What? Because it, you know, basically pulled together a whole bunch of very high popular information that has an algorithmic learning element to it. It was presented this way.

That doesn’t mean it’s everything. That doesn’t mean that it’s the answer inside of AI too. It’s how you receive and what you do with that data as opposed to taking it for just face value.

Not Driving and Planning Your First Foods

So that was the overall of my 100 hour fast with a video that maybe feels like 100 hours. My, my experience with it. My biggest things that I would say though, regardless to everyone, if you’re not feeling 100% and you’re doing a fast, especially a long fast, consider not driving.

If you are not sure, you know about the experience, to have certain foods, like broth, like hard boiled eggs, like a probiotic kind of drink there so that when you get off it’s a little bit easier. That’s one thing that has been across the board that you know, after a very long fast you’re not going to want to load your stomach up all of a sudden.

That that’s an objective fact across the board. Anyways, that’s my experience. That’s my 100 hour fast. I hope it’s of interest or of help or just of, I don’t know, something for you.

That’s all I got.

A fast with electrolytes may not be a water fast, since a water fast can mean water and nothing else: no salt, no electrolytes, no teas and no sport drinks. People who add drinks or food while calling it a water fast may have redefined a fast.

Can fasting help you stay calm during conflict?

Fasting may help some people stay calm during conflict, in Loren Weisman’s experience. On day three of his fast, a stream of insults did not seem to hit, and he felt stronger in choosing not to return insult for insult, in his experience.

Why do fasting results differ from person to person?

Fasting results can differ because people come from different bodies, ages, experiences and diets. Many fasting videos may share one person’s experience and then claim it is what fasting will do for you, so treating such claims, even ones from AI, as opinion and experience can help.
