## Summary

This video explains how konjac fiber, specifically glucomannan, can mimic the effects of weight loss drugs by stimulating the body's own GLP-1 hormone production. The presenter cites a 2020 meta-analysis showing significant weight loss, especially in women, and provides a five-step plan to incorporate konjac into daily meals.

### Key Points

- **Konjac fiber as a natural GLP-1 booster** [00:16] — A 2020 meta-analysis of 225 adults found that konjac fiber caused more weight loss than any other fiber, with double the effect in women.
- **Understanding konjac and glucomannan** [01:29] — Konjac is a fiber found in noodles (shirataki/miracle noodles). It contains glucomannan, a soluble fiber that absorbs 50 times its weight in water, forming a gel that feeds microbes producing GLP-1.
- **Weight loss results from konjac** [02:58] — People who added glucomannan through konjac noodles lost over two pounds more than the placebo group in an eight-week study.
- **Supplements are ineffective** [04:15] — A 2014 review of eight studies found glucomannan supplements showed no significant weight loss, so food sources like konjac noodles are preferred.
- **Fiber for different diets** [05:12] — The presenter introduces 'ketobiotic' (keto with more fiber) and emphasizes fiber as a bridge for those coming from ultra-processed diets, aiding blood sugar regulation and appetite control.
- **No exit ramp for weight loss drugs** [06:12] — Weight loss drugs lack an off-ramp; konjac noodles can help taper off drugs by promoting natural GLP-1 production.
- **Five steps to apply konjac** [07:08] — Steps: 1) Find konjac root/shirataki noodles, 2) Pre-load fiber before meals, 3) Pair fiber with protein, 4) Do an eight-week konjac reset, 5) Track hunger levels daily.
- **Konjac reduces food intake** [09:43] — A 2018 British Journal of Nutrition study found konjac gel noodles reduced how much people ate afterward without increasing hunger.
- **Gender differences in results** [13:29] — In the meta-analysis, men lost over two pounds, but women lost over four pounds, likely due to fiber helping break down estrogen and cortisol, which are stored as belly fat.
- **Three action steps** [14:39] — 1) Buy konjac noodles, 2) Preload every meal with fiber (konjac, salad, psyllium husk), 3) Join the eight-week konjac challenge and track hunger changes.

### Conclusion

Konjac fiber offers a natural, food-based approach to boosting GLP-1 and supporting weight loss, with particular benefits for women. By incorporating konjac noodles and preloading fiber before meals, viewers can potentially reduce appetite and improve metabolic health without relying on supplements or drugs.

## Transcript

I know so many of you are doing all the right things but you still don't feel like you're burning fat and that's really frustrating and then you watch all these people go on the weight loss drugs and all of a sudden they are instantly skinny. In this video I want to show you specifically
how you can use one type of fiber that will give you a very similar result as those weight loss There was a 2020 study in obesity medicine.
It was a meta-analysis of 225 different adults. And the researchers found that eating more of one specific fiber that I actually promise you you're probably not eating
caused more weight loss than any other fiber I can teach you. And what's really exciting is it was twice as effective in women. So by the end of this video, you're going to know this fiber.
I'm going to show you the fiber. And we're going to talk about how you can start to get the results that the people in the study got.
So here's what the study found. We have to understand we make our own GLP-1 hormone. So all these people that are getting results injecting GLP-1 hormones, you can get it by understanding the chemistry of your gut.
And here is what this particular study found is that there is a fiber known as konjac. Put in the comments if you've heard of this. It's a very specific fiber that you actually see in noodles.
So I've got some noodles right here. this is konjac noodles. So it operates and can taste a lot like regular noodles, like rice
noodles. It would be a great replacement for pasta. So what this study found that was so critical is it pulled six clinical trials together. That's what a meta-analysis is. It's looking at
all of several studies together. I personally love meta-analysis. And so they had 225 people, and what they found is the researchers identified a specific nutrient known as glucomannan,
and that glucomannan was found in a fiber known as konjac. Now, I know a lot of you are like, what? What did she just say? Sit with me for a second, because the people who added in more glucomannan through this konjac,
which is noodles, konjac comes in noodles. They're also known as miracle noodles. You can see why. Is that these people lost over two pounds more than the placebo group.
So this is a really powerful fiber. And what konjac has in it is this glucomannan. And glucomannan is a soluble fiber that absorbs up to 50 times its weight in water, forming a thick gel in your stomach that starts to feed the microbes that make the GLP-1 hormone.
Now, the study lasted eight weeks, and in one of the studies that they looked at, they showed that if you go eight weeks or longer, you could actually get an even deeper result
than if you just started randomly putting konjac noodles into your system. If you consistently started to look at adding this in, maybe those of you who are pasta lovers,
those of you who have been keto and you're missing carbs this could be literally the miracle noodle that starts to get your body making its own glp hormone and burning fat it adding something in a very trendy thing right now is fiber supplements And so I looked into this to just see like do we have glucomannan fiber supplements
And, yeah, you can order a bunch on Amazon, and there's tons of them, but I don't want you to waste your money. So there was a 2014 review that looked at eight different studies,
and they found that glucomannan supplements showed no significant weight loss overall. So don't waste your time and money looking for supplements. We got to go back to food.
And a lot of the studies that I look at for you all are showing that, that food is more powerful than supplements. The other mistake that a lot of people make is they start to cut carbs so much that they cut fiber.
So this is why in all my books, I've come up with something called ketobiotic. And ketobiotic is a form of keto where you can have more fiber. So if you're not familiar with that, you can check out my books, any of them.
Fast as a Girl was the one that I first introduced with it. But the reason that I want to tell you this is that we sort of have two types of people who are watching my videos. Some of you are a hardcore carnivore.
Some of you are hardcore keto, and I want to encourage you to make sure you're getting enough fiber because then you can start to bring in things like Miracle Noodles. You also can bring in fiber that will help you break hormones down.
And then on the other end of the spectrum, we have some of you that are coming directly from an ultra-processed food diet. And if that's you, fiber is so good. It's such a beautiful bridge to be able to bring you into more blood sugar regulation,
start to kill your appetite, and it can start to get you off that ultra-processed food addiction. Fiber is that incredible bridge. Now, the other mistake, I mean, you can call it a mistake.
I know some people are getting great results with the weight loss drugs, but I just want to point out that there's no exit ramp for these weight loss drugs. So a lot of people have had this poor relationship to food,
and then they just go to the weight loss drugs because they're like, forget it, I just need to have a full reset. I get it. I get why you, and it's effective. But the problem is there is no off-ramp.
So if you're also on the drugs, I just want to point out that you can use Miracle Noodles as a way to slowly paper off those drugs and to be able to get your own GLP-1s going without having to rely
on expensive medications. Here are your five steps that I want you to apply immediately. One, go find you some konjac root. So it's also called shirataki noodles.
I'll put the name here so you can see it. It's also known as miracle noodles. It's really interesting. if you start to look for it you will find it so let me know if you if you have trouble finding it
let me know if you have been using konjac noodles what you think of it but I highly recommend that you look at bringing in that that noodle on a regular basis now I want to remind you
that again it's always better to get glucomannan in konjac noodles as opposed to finding the supplement. Okay, step number two. I want you to get in the habit of pre-loading your fiber before
a meal. So there's a couple things you can do. These noodles actually will work like cold. You don have to heat them up So maybe you just put some grass butter in them and you eat them before your protein They fiber Remember how I say you have fiber first Even though they don look like lettuce they fiber So you could maybe do it as an appetizer to your meal
Some of you are really enjoying psyllium husk as a pre-fiber loading meal. Like an appetizer with fiber will absolutely help you with your appetite and weight loss
and the GLP-1 hormone. So get in that habit of doing some kind of fiber before every single meal. And if you try the miracle noodles, let me know.
Okay, step number three. Once you look at your fiber habits, I really want you to start carrying your fiber with protein. So this could look like a salad and then a grass-fed steak.
Or maybe you're just doing a green salad. and those of you that are plant-based, maybe then you go into some beans and rice. But I want to make sure that we're always pairing fiber with protein.
So again, protein raises metabolism and fiber slows digestion down. And combined, they are incredible for appetite suppression.
So that food noise that a lot of you are experiencing, the food noise will go away when you put fiber with protein together. Now, I want to point out that there was a 2018 British Journal of Nutrition
that found konjac gel noodles reduced how much people ate after they ate the noodles without making them feel any hungrier.
So this was a British Journal of Nutrition 2018 study that said when you had konjac noodles as your appetizer, that what you didn't eat as much afterwards.
So again, many different ways to start to look at these noodles. Okay, so step number four. Here's what I really want to make sure you do is an eight-week konjac reset window.
So pick a start date, and I want you to mark eight weeks out on your calendar, and I want you to take one measurement. Maybe it's the weight. I don't really love the scale.
Maybe it's waist circumference. I'd love for you to maybe take that as your one measurement. And I want you for eight weeks to make a commitment.
I'm not telling you every day, maybe every other day, where you are putting these con jaff noodles in before you eat your meal. This was a whole pack. You don't have to, like, do a whole bowl full.
It could be a little tiny amount, but let's look at it like apple cider vinegar. Let's look at it like a tool for GLP-1 hormones. Okay, now step number five is I want you to start to track how your body does adding these
konjac noodles in. So you're not going to see immediate results around the waist circumference. So you could do a hunger scale. every single day at the end of the day ask yourself how hungry you are give it on a scale of
zero to ten how hungry was I today and then what you will do is and I would mark it down because you want to be able to see it over time so you might look and see that like oh I was at a hunger
level of 10, but then I did my contract challenge, and now my hunger level has started to go down over the course of weeks to a 5 or to a 4. It's an easy test to do. There was a great YouTube
listener. We get so many of your comments that get sent to me, or I'm reading them on a daily basis, but this one was a 44 woman who watched a video like this and she wrote in her comments that I am 14 days into my high fiber high protein this is what I teaching you to do diet and I incorporating overnight fasting and I can
feel myself rebuilding my own GLP-1 and she's been doing this for two weeks and here's what she noticed. She can go five to six hours stretches without meals. She was having to
eat every couple of hours. She doesn't think about food anymore. She enjoys every bite she takes. She's back eating food again. The villain isn't fruit. And her brain, as she puts it, is operating
as it is intended. And her diet feels effortless. We are a chemistry experiment. And when you learn the chemistry of food, you start to see that bringing foods in can actually help you start
to lose weight. So don't beat yourself up because there's a lot of reason that you gained weight because you just didn't get the right information and now you're getting the right information. I also want to point out that there is a difference between men and women. So this analysis, the one I
started off with, the researchers looked at how men and women responded to konjac differently. And what they found was that it was the men that lost over two pounds, but the women lost over
four pounds. So stay an eight-week trial of adding konjac in on most days or on every other day, and women got a better result.
Why is that? Because when we feed our microbes fiber like glucomannan, that is in konjac noodles, what happens is it starts to be able to break down hormones.
And when you break estrogen down, you don't store estrogen. When you break cortisol down, you don't store cortisol. These are hormones that will be stored around your belly. and when you start to add in T fibers, the body has no reason to store it there,
which is why women got to double the result as men because a lot of our visceral fat is coming from cortisol and a drop in estrogen. Here are your three action steps I want you to take immediately.
I want you to go to the store and I want you to find the Kaja. You can do it. Go find it. You're going to be amazed. and I want you to start incorporating it into a regular meal, whatever meal that is.
Two, you're going to start cyber loading before every single meal. It may be contact. If you're doing the eight-week challenge, it may be a bowl of salad. It might be, you know, carrots and some kind of vegetable.
Or maybe it's psyllium husk in water. But you are going to preload every meal with fiber, and then you build that meal around protein after that.
And actually, step number three, who's joining me on the eight-week challenge of Tom Jack noodles? Let me know, because I want you to pick your date, when you're going to start, so that you can look at over eight weeks how your hunger changes by adding these miracle noodles in.
Now if you want more on belly fat, I've done a lot of videos here, so check out this video on why belly fat explodes after 40 and the 3 step fix for it. I am here of service to you, I appreciate all of you who share my videos and you come
back to watch them all. I am bringing you the latest science I know on metabolic health and don't give up on yourself. I haven't given up on you, please don't give up on yourself because it's information like
this that's very much the difference between getting a result and not getting a result. As always, I hope that helps. If this helps, you're not going to want to stop there. I'll stop with this video.
