I have a passion for empowering people through simple, small strategies that can lead to meaningful, long-term health improvements. Today's focus is on one of the most underrated and under-consumed nutrients, fiber, and the powerful concept of "fiber first."

Inspired by Jessie Inchauspé, known as the Glucose Goddess and author of Glucose Revolution, the fiber-first strategy encourages eating fiber-rich foods at the beginning of meals. I explain how this simple sequencing can significantly improve blood sugar control, digestion, cardiovascular health, and satiety—without restrictive dieting, calorie counting, or obsessing over macros.

The episode breaks down what fiber really is, clarifying that while fiber supports bowel regularity, its primary role is feeding the gut microbiome. I also explain the differences between soluble and insoluble fiber and highlight how fiber forms a beneficial mesh in the digestive tract, slowing glucose absorption and supporting metabolic health.

Listeners will learn who benefits most from the fiber-first strategy, including individuals with blood sugar challenges, cardiovascular risk, weight concerns, and those using GLP-1 medications. I also explain when fiber intake should be approached cautiously, such as during acute gastrointestinal flare-ups, and provide safe, practical tips for increasing fiber gradually to avoid discomfort.

I encourage listeners to focus on building balanced plates rich in fruits, vegetables, legumes, seeds, and whole grains while prioritizing hydration. Finally, I challenge you to try the fiber-first approach for one meal or one day and observe how it impacts cravings, fullness, and energy levels.

Closing with a reminder of the Golden Rule from Matthew 7:12, I encourage you to care for their health and extend kindness to others. Please share this episode and continue taking steps toward better gut, heart, and overall health.

Thank you for listening to Healthy California.

My name is Linda Brown.

00:01:20

I am your physical therapist and functional nutritionist, health coach, and educator here in California.

00:01:26

I am also someone who deeply believes in the power of small, simple strategies to make big impacts in your life.

00:01:34

Today, we are going to talk about the most underrated, under-consumed, and over-complicated nutrients, fiber.

00:01:44

We don't get enough of it.

00:01:46

And more specifically, we're going to talk about the concept of fiber first.

00:01:49

This was first described by Jesse Inchaupe.

00:01:53

She's the glucose goddess and she has a book called Glucose Revolution.

00:01:57

And fiber first is just the concept, it's an easy, simple concept of eating fiber first.

00:02:04

This is a strategy that can transform glucose regulation, you know, diabetes, obesity, digestion, blood sugar control, cardiovascular risk, which I talked about last week, and can even make you feel fuller longer without counting calories, cutting out food groups or obsessing over macros.

00:02:26

Macros are your fats, carbs, and proteins, which I have talked about and mentioned last week as well.

00:02:31

But today we're going to talk about fiber first, what it means, the science behind it, who should use this strategy, who shouldn't, and then just practical ways we can increase our fiber intake without discomfort.

00:02:44

So let's get started into this.

00:02:47

What is fiber?

00:02:48

So it's a myth that fiber is what we eat when we bulk up our stool.

00:02:54

Makes us more regular.

00:02:55

Does it do that?

00:02:56

Yes, but is that why we eat it?

00:02:58

No.

00:03:00

That's not the reason we eat fiber.

00:03:02

For hundreds of years, thousands of years maybe even, we didn't eat fiber just because we were always irregular.

00:03:10

We ate fiber because our body needs fiber and our gut microbiome especially needs fiber.

00:03:17

So fiber is a category of carbohydrates.

00:03:20

You find it in plants, it's the skeleton of plants.

00:03:23

And it's not completely digestible in our intestines.

00:03:26

But the microbiome in our intestines need it.

00:03:30

So there are different types of fiber.

00:03:31

There's soluble and insoluble fiber.

00:03:33

Soluble just means soluble in water or insoluble in water.

00:03:36

So a soluble fiber slows down digestion and increases the feeling of fullness.

00:03:43

And insoluble fiber plays an important role in detoxification and bulking up your stool.

00:03:48

So insoluble fiber is the fiber that helps with the bulking part of that.

00:03:54

But in general, fiber is needed by our gut microbiome.

00:03:58

Eating fiber first creates like a viscous mesh in our small intestine and slows down the absorption of glucose from like the rest of the meal.

00:04:07

So proteins are broken down in our stomach mainly, fats are broken down in our small intestines,

00:04:12

And so we're carbs, but fiber is fermented lower down in the GI in our large intestine by our gut microbiome.

00:04:22

Fiber first is a simple sequencing strategy, just pretty much meaning starting with the fiber.

00:04:29

At dinner you can eat a small side salad, broccoli, handful of almonds.

00:04:35

So the order matters.

00:04:36

Fiber, then proteins and fats, and then starches and sugars.

00:04:42

And starches and sugars are also carbs.

00:04:44

And I've talked about in the past eating proteins first.

00:04:47

Proteins always, before your carbs.

00:04:51

However, fiber or proteins, if you look at the new food pyramid, that's all the largest part of your meal.

00:04:58

So I don't really care what you eat first, just don't eat your starches and your sugars first.

00:05:05

And the fiber first, I completely agree with fiber first concept.

00:05:09

We'll talk a little bit more about why.

00:05:11

So you're eating your fiber-rich foods at the beginning of a meal, before starches, before sweets, before the fast-absorbing carbs.

00:05:18

And this could be a small salad, a cup of vegetables, a handful of berries, a veggie soup, and maybe even like a small teaspoon of chia pudding or, you know, putting chia on your salad.

00:05:32

That's a good form of fiber.

00:05:33

And when you dine out, order appetizers that have fiber in it before you eat your bread.

00:05:40

Because you know the restaurants are always going to bring out the bread.

00:05:43

And that's a carb that's easily digested and increases your blood sugar pretty fast.

00:05:48

So the goal is not perfection, It's simply prioritizing fiber at the start of your meal so that digestion, blood sugar, and the feeling of fullness work in your favor.

00:06:00

In your favor, not just the feeling of fullness, but in your favor also in the sense of being healthy.

00:06:07

It's healthier to eat fiber first, not just it's going to make you fuller.

00:06:13

That's a secondary response.

00:06:15

This support is supported by research showing that the order in which we eat our foods significantly impacts glucose response and insulin demand, and of course the feeling of fullness.

00:06:28

But the reason why this is important these days is because diabetes is increasing so much.

00:06:36

If you've listened to my previous podcast, you will know that cardiovascular disease is increasing, diabetes is increasing.

00:06:42

All these chronic diseases are only increasing.

00:06:48

And they're diseases that we can change by making simple changes.

00:06:53

Like even making a simple change by what you eat first can impact your health so greatly.

00:07:01

And that's why I'm bringing this up.

00:07:02

It's just a simple change.

00:07:04

Anybody could do this.

00:07:05

So let's go over the benefits of fiber firsts.

00:07:08

I'm going to list them and then we'll go over them more in depth.

00:07:12

So the benefits of fiber first, better blood sugar control, improved feeling of fullness, appetite regulation, supports the gut health or microbiome, cardiovascular protection, or pretty much chronic disease in general, including autoimmune diseases.

00:07:31

improved bowel regularity, and improved neurological impact.

00:07:37

So it helps with your nerves as well.

00:07:39

So let's go over each one of those separately.

00:07:42

So blood sugar control.

00:07:43

When fiber coats the stomach and the small intestines, it slows glucose absorption.

00:07:51

This leads to lower sugar spikes.

00:07:54

It can lower your glucose spikes by 30%, 30 to 40%.

00:07:59

Now just imagine you're lowering your glucose spike by 30 to 40 percent, and then, like I had mentioned before, in previous podcasts, going for a 15 or 20 minute walk after a meal could also lower your blood glucose.

00:08:15

So just doing those two things, boom, you're regulating your blood sugar.

00:08:20

Another benefit is with the blood sugar control is it lowers your insulin, which means that there's less insulin production, which is a game changer for weight management, obesity, diabetes.

00:08:34

You have more stable energy because you're not having those spikes.

00:08:37

You're not having that 3 o'clock afternoon crash where you're tired and you feel like you need to grab a candy bar or a cup of coffee.

00:08:47

So having a more stable glucose control is going to inhibit those spikes and those crashes.

00:08:54

So you're going to have fewer cravings in the day.

00:08:56

So this is helpful with people with insulin resistance, pre-diabetes or diabetes, trouble with weight, PCOS, polycystic ovarian syndrome, has a lot to do with blood sugar dysregulation.

00:09:10

Stable blood sugar and slower digestion reduce inflammatory signaling, so it reduces inflammation.

00:09:17

And you've heard me say this many times, inflammation is the cause of most, if not all, chronic diseases.

00:09:25

And this is especially important for people with autoimmune disorders as well.

00:09:31

So another benefit of fiber first is the feeling of fullness or appetite regulation.

00:09:37

So fiber increases that stretch in your stomach.

00:09:41

So it's that bulking agent part of the fiber.

00:09:44

However, it's not the fact that it's bulking as much as it is the stretch part of your intestine is a signal.

00:09:54

It's a signal to slow things down.

00:09:56

So this means you feel full sooner, which means it triggers your hunger hormones.

00:10:03

And then it also releases a natural peptide called GLP-1.

00:10:07

And we have heard GLP-1 a lot in the news and all over TV.

00:10:14

GLP-1 is a medication, like Ozempic, for example,

00:10:19

It's a medication that slows gastric emptying and decreases hunger, controls blood sugar regulation, and it's being prescribed more because of its effects.

00:10:29

So GLP-1 is made in our intestines.

00:10:33

So we do make it, and it tells your brain that you're full.

00:10:36

You stay fuller longer.

00:10:38

I'm not talking about GLP-1, I'm just talking about the stretch receptors in your stomach.

00:10:43

You stay fuller longer, which means you naturally just reduce your portion sizes when you're eating as well.

00:10:50

So this is why fiber first is a powerful tool for weight management and for people on GLP-1 medications.

00:10:56

So another benefit of fiber first is your gut health, your microbiome.

00:11:03

Fiber feeds your beneficial gut bacteria, producing short-chain fatty acids like butyrate, which support reduced inflammation.

00:11:12

It's a prebiotic, the gut barrier in general, better immune function, lower risk of colon cancer.

00:11:19

So it reduces inflammation by these short-chain fatty acids, which are produced by bacteria in our gut.

00:11:29

And when these bacteria ferment, they produce these short-chain fatty acids, which then help reduce inflammation and improve brain health as well.

00:11:39

Improves everything.

00:11:40

So the fermentation process is created by bacteria, and our body needs that.

00:11:48

So we need a healthy gut microbiome to produce these molecules that our body depends on.

00:11:56

So diverse fiber means a diverse microbiome, because different bacteria in our stomach feeds off of different types of foods.

00:12:04

Another benefit of fiber is the cardiovascular protection.

00:12:08

I talked about cardiovascular disease last week,

00:12:12

And so this is a continuation of that because cardiovascular disease is a chronic inflammatory disease and soluble fiber binds to cholesterol in the gut and helps remove it from the body.

00:12:23

Fiber can help reduce cholesterol, which then reduces cardiovascular disease.

00:12:27

And given that heart disease remains the leading cause of death in the US, this is a major benefit.

00:12:34

Just by eating fiber first, you can decrease your cardiovascular risk.

00:12:39

Simple.

00:12:40

Another benefit is improved bowel regularity.

00:12:43

So this is the bulking part that we know fiber to be a bulking agent for our stool and stool softener.

00:12:53

So this helps with constipation, with hemorrhoids, with diverticulitis.

00:13:00

So that's another benefit of fiber first, of just fiber in general.

00:13:04

And then another benefit is the benefit it has on our nerves, the impact on our nerves.

00:13:12

So there's a link between healthy gut microbiome and the neurological system.

00:13:17

And they call this a gut-brain axis.

00:13:19

And there's medical specialties called neuronutrition or psychobiotics because the gut-brain axis is closely related, related enough to have specialties in our medical field that relate what we put in our body through food and our brain.

00:13:39

So who benefits from fiber first?

00:13:42

Most everyone benefits from fiber first, but particularly helpful with people that have blood sugar issues.

00:13:47

So pre-diabetes, type 2 diabetes, insulin resistance, PCOS, and then there's a chronic diseases or inflammatory diseases like cardiovascular disease, people with high cholesterol or high LDL, high triglycerides for sure, hypertension, or people just even with a family history of all this.

00:14:09

If you have a family history of this, then you can make simple changes now for prevention in the future.

00:14:17

And again, this is a simple fix.

00:14:20

Who else benefits?

00:14:21

People on GLP-1 medications.

00:14:24

And there are more and more people on GLP-1 medications.

00:14:28

And again, GLP-1 medications help you with blood sugar regulation, feeling of fullness, decreasing diabetic risk.

00:14:38

So fiber helps with constipation because the GLP-1 also slows gastric emptying and fiber also slows gastric emptying.

00:14:49

So you put those two together and you can really get constipated.

00:14:53

Fiber will help with that, but you gotta be careful, and we'll go over that in a second.

00:14:57

Fiber will help with constipation, satiety, nutrient density, and blood sugar stability.

00:15:03

The nutrient density is important because when we are taking a GLP-1 medication, our appetite decreases, we don't get enough nutrients.

00:15:14

And that's a big problem, especially when we don't eat proteins.

00:15:17

We lose muscle mass and we need muscle on our body for many reasons.

00:15:23

So nutrient density, you can get more nutrients from a nutrient-dense food than you can from a donut or Cheetos.

00:15:32

So fiber is good for people on GLP-1 medications.

00:15:36

It's also good for people trying to lose weight because fiber can increase the feeling of fullness, which reduces overeating.

00:15:44

Fiber supports motility and stool formation.

00:15:49

Fiber supports gut integrity and reduces inflammatory load.

00:15:53

So there's a lot of reasons people would benefit from fiber and fiber first.

00:16:01

Who should not use fiber first?

00:16:05

So fiber is powerful.

00:16:07

And not everyone in every situation should eat a lot of fiber.

00:16:12

So if you have acute GI flares, so you should avoid high fiber during those acute GI flares, like if you have active Crohn's disease, active ulcerative colitis, severe IBS flare-ups, active diverticulitis, post-surgical bowel rest, or even pre-colonoscopy you should avoid fiber, high fibers.

00:16:39

However, fiber is so good for your gut that you can't be low fiber forever.

00:16:46

And small bits of fiber is so important, eventually your gut can repair itself and a lot of these flare-ups can actually go away.

00:16:57

And even like the diverticulitis, some people have been told that if you have had diverticulitis, that you shouldn't eat seeds, berries, because berries have seeds in them.

00:17:10

And new research shows that this is not actually true, because eating berries is more beneficial than the risk of eating the seeds.

00:17:20

So if you avoid foods because you're afraid of the seeds, then your gut is actually getting more unhealthy.

00:17:27

And that's more detrimental than the risk of having a seed lodge into your diverticulitis pouch and causing inflammation.

00:17:36

It's the inflammatory process of having an unhealthy gut that's the problem, not having a seed trapped in there causing the inflammation.

00:17:45

The inflammation is already there.

00:17:47

So you need to get the inflammation down.

00:17:50

Who else should not eat a lot of fiber?

00:17:53

So people that already have trouble with constipation may not need to add more fiber.

00:18:01

I don't want to say less fiber, but you just need to be careful with the fiber that you eat because bulking on top of constipation doesn't always solve the problem.

00:18:10

And if you are on a GLP-1, you want to start your fiber slowly, or if you have SIBO, small intestinal bacterial overgrowth, you want to start your fiber slowly.

00:18:23

It's just, if you have flare-ups, you need to eat less of it initially, but it's still important that you're feeding that gut microbiome and getting your intestines healthy.

00:18:33

And if you have difficulty swallowing, you might want to eat an easily digestible form of fiber.

00:18:42

And then people who don't drink enough water can cause constipation and can cause fiber to get stuck in your throat.

00:18:48

Drinking water is so important for many reasons, but this is just another reason to drink more water is because you're going to be eating more fiber.

00:18:58

And people with strictures in their bowels, fiber may be contraindicated for a certain point of time, depending on the severity of it.

00:19:07

That's really up to your doctor.

00:19:08

So if you have a stricture, I would talk to your doctor about what fiber you can eat, but you still need to have fiber.

00:19:16

So how do you increase fiber safely?

00:19:18

Well, I'm not going to go over how much fiber is recommended, because that's just another number to think about how many grams per day, per body weight.

00:19:29

And I'm not going to talk about how many grams a day of fiber you should have, because I don't want you to think about the numbers.

00:19:35

I want you to think about what your plate looks like.

00:19:38

If you look at the new food pyramid, or even the previous MyPlate, picture, most of your plate should be fiber, fiber and proteins.

00:19:48

But I want you to think about what your plate looks like more importantly than anything.

00:19:53

Your plate should have a lot of fruits and vegetables on there every meal of the day.

00:19:58

Increase it just a little at a time.

00:20:00

So I'm not saying all of a sudden go and have a big salad.

00:20:03

Maybe throw a few chia seeds into a drink or into like a chia pudding or over a salad.

00:20:11

maybe have a few almonds, maybe have cooked carrots, fruit without peels.

00:20:18

So just start slow.

00:20:20

If you eat too much too fast, you're going to have bloating, you're going to have gas, cramping, constipation.

00:20:26

It's going to be too much.

00:20:28

You're going to be very uncomfortable.

00:20:30

So start off with lightly cooked vegetables and take the skins and peels off the fruit for right now.

00:20:38

And this is just if you're having trouble with fiber intake.

00:20:42

If you're not, then by all means, keep those peels on your fruits and vegetables.

00:20:49

Don't peel the apple.

00:20:50

Don't peel a carrot.

00:20:51

And then of course, you want to hydrate.

00:20:54

If you're having trouble increasing your fiber intake, then hydrate.

00:20:59

Six to 8 cups a day or the formula that I like to use, which is simple, is half your body weight in ounces.

00:21:06

So if you're 200 pounds, half your body weight would be 100.

00:21:09

You'd be drinking 100 ounces of water a day.

00:21:13

Half your body weight in ounces.

00:21:15

And if that seems like a lot, if you're not even getting 1/4 of that, then you need to figure out how you can add more liquids into your day.

00:21:25

And if you're active or it's hot outside, then you may need to increase that and then add electrolytes to your water. electrolytes or even like lemon juice.

00:21:34

Squeeze a lemon or a lime into that, into the water.

00:21:38

And then another way you can increase your fiber intake slowly is to take insoluble fiber.

00:21:46

Soluble fiber is the fiber that is broken down by water.

00:21:50

It's water soluble.

00:21:52

So oats, chia seeds, flax seeds, apples, pears, beans, lentils, they're all soluble fibers.

00:22:00

And you can have a little bit of that to start off.

00:22:03

Again, don't go and all of a sudden eat a big bowl of lentils every single day.

00:22:08

You just start slowly.

00:22:10

Lentils are delicious, by the way.

00:22:11

And if you're not eating a fruit or vegetable every meal, you know, a few servings of them every meal, then start adding a little bit to every meal.

00:22:22

Maybe for breakfast, have a handful of berries in your oatmeal or yogurt.

00:22:28

Lunch, have a salad, dinner, have more vegetables.

00:22:32

So just add a little bit, but you should be having fruits and or vegetables every single meal.

00:22:38

If you haven't been doing that, then start there.

00:22:40

Using the fiber first sequence, you want to start with a small salad, cup of vegetables, handful of berries, maybe a veggie soup, lentil soup, and then add seeds.

00:22:50

Add seeds like chia seeds, flax seeds, hemp seeds.

00:22:54

You can add them to your smoothies, your yogurt, your oatmeal, your soups, your salads, it doesn't take much.

00:23:01

Chia seeds and flax seeds, hemp seeds, doesn't take much and they pack a punch.

00:23:06

So put them in your pantry and get used to them being part of your daily meals.

00:23:12

It's easy enough just to sprinkle them on the food.

00:23:16

And if you're going to choose a whole grain, choose quinoa, barley, oats, brown rice, because they add a steady form of energy, a steady form of fiber.

00:23:28

They're definitely not going to spike your glucose.

00:23:31

And I would choose those grains, the quinoa, the barleys, the oats, brown rices, over whole wheat, honestly.

00:23:39

I'm not a fan of the whole wheat, mostly just because of the gluten in it.

00:23:44

And I'm not anti-gluten, I'm just too much gluten.

00:23:48

We have too much gluten in our diet.

00:23:50

And then also, we can increase our legumes.

00:23:54

Beans and lentils, they're fiber powerhouses, but they're also a good source of proteins.

00:24:00

So talk about nutrient dense.

00:24:02

You get your proteins and your fibers in one sitting.

00:24:06

So try adding the legumes to your two to four meals a week.

00:24:11

That's not hard.

00:24:12

With beans and lentils, you can cook a whole pot of beans or lentils and they keep well.

00:24:18

They store well in the refrigerator.

00:24:19

So you can cook a lot and have it throughout the week.

00:24:22

So fiber first is not about any sort of restriction, It's just about reordering what you're eating first.

00:24:29

So I want to challenge you to try fiber first for a day, maybe even just for a meal.

00:24:37

Let's start with trying fiber first for just a meal and see if you notice any changes in how much you're craving after that.

00:24:46

And if that works for you, then try it for a day.

00:24:50

I don't want you to try it for a meal and say, well, that didn't do anything for me.

00:24:54

I'm just not, this isn't for me.

00:24:55

I want you to try it for one meal, and then I also want you to try it for a day, a whole day, and eat your fiber first.

00:25:03

If you're going to a restaurant, that's a great time to try ordering something, eating your fiber first, and then having your bread, if you eat bread, having it later.

00:25:15

I'm not trying to take away your bread from you right now.

00:25:17

I'm just trying to have you reorder how you're going to eat your meals.

00:25:22

And just try it.

00:25:24

So Fiber First is one of the simplest, most powerful nutrient strategies.

00:25:29

Simple.

00:25:30

It supports metabolic health, gut health, cardiovascular health, reduces inflammation, which then helps long-term disease prevention just by making simple changes.

00:25:42

So start small, start slow.

00:25:45

Start with one meal and then start with a day's worth of meals.

00:25:50

I really want you to think about it because it is so simple.

00:25:53

Why would you not incorporate it?

00:25:56

So I just want you to think about that.

00:25:58

So I also want to end on my verse of the day and it's by Matthew 7.12.

00:26:06

And it says, so whatever you wish that others would do for you, do also to them, 

for this is the law and the prophets.

00:26:15

So this is like the golden rule, right?

00:26:17

So do unto others as you would want them to do to you.

00:26:20

So in general, I just want you to live a long time.

00:26:24

I want you to be good to people, and I want you to live a healthy life.

00:26:27

And it won't go unnoticed by people, and it won't go unnoticed by God.

00:26:32

So do unto others as you would like them to do unto you, and that's all part of staying healthy.

00:26:37

So thank you for joining me today.
