Are you ready to concentrate on the fiber and enjoy the benefits? We are here to help you find signs of low fiber intake – and how to fix it.
The risk of not getting enough fiber
Knowing what goes wrong when you don’t eat enough fiber will help in motivate you to make it a priority. A low-fiber diet does not only ruin your digestion. It can lead to more serious health problems over timeinclude (3):
- Increased risk of heart disease
- Blood glucose fluctuations
- It’s difficult to maintain a healthy weight
- Increased risk of colon cancer
Symptoms of low fiber lifestyle
Symptoms could be subtle, like vague fatigue, and like constipation, they were more obvious, and did not connect to diet.
Some of the most important indications that your fiber intake can use boost are:
constipation
The fibers add bulk to the stool, helping everything move smoothly through the intestines. Without sufficient fiber, the stool can be hard, dry and difficult to pass, leading to unpleasant and rare defecation.
And if constipation is a way of life thanks to a low fiber diet, it can cause bloating, stomach discomfortand hemo is there because he gets nervous while using the bathroom.
Fiber, especially soluble fiber in foods such as oats and beans, can alleviate this problem. It helps to draw water into the intestines and soften the stool. Insoluble fiber from whole grains and certain vegetables is also useful. It functions like a broom that cleans your system and keeps things moving (4).

Losing weight is hard
If you’re eating with a calorie deficit but still struggle to lose weight, fiber may be a lack of ingredients in your diet. High-fiber foods take time to digest. This helps prevent hunger immediately after a meal. (1).
Fiber also helps to keep blood sugar levels in a uniform keel. This means there’s less craving for quick fixes like snacks like sugar (6). Studies show that people who eat more fiber naturally burn up up to 10% less calories throughout the day (7).
So, if weight loss is your goal, you might exchange refined carbohydrates for fiber-rich whole grains, legumes and vegetables.

Energy shortage
Do you know of the blood sugar collision that sends you to the vending machine at 3pm? Well, they also affect your energy levels throughout the day.
Without enough fiber to slow digestion, carbohydrates can break down into sugar more quickly, causing bursts of energy, followed by a sudden nap (6).
If you manage to feel something after a meal or suffer from brain fog, try increasing your fiber intake.
It exchanges refined carbohydrates for whole grains, adds vegetable meals to your meals, and eats nuts and fruit to provide a steady release of the energy your body needs to stay stable.
Irregular intestinal movements
Constipation is not just a digestive condition of a low-fiber diet. You may also notice unpredictable or irregular bathroom habits.
Fiber helps regulate digestion, so a low-fiber diet can make your digestive system feel bloated, uncomfortable, or unpredictable (8). No matter which side of your intestine tends to try to lean, the fibers can help you regulate it.

Irritable Bowel Syndrome (IBS) Flare Up
Irritable bowel syndrome, or IBS, is a common condition that can cause you to experience diarrhea, constipation, or a combination of the two. One in 20 people in the US lives with IBS (9).
If you’re one of them, Fibers can play an important role in managing IBS symptoms. Too little fiber in your diet can worsen constipation and increase symptoms of bloating, gas, or convulsions (9).
On the other hand, focusing on eating enough fiber can help improve constipation, slow diarrhea, and regulate the intestines in response to irregular symptoms (generally)4, 8).
Specifically, soluble fibers are milder in the intestine than insoluble fibers (9). Highly soluble fiber vegetables and carrots, such as sweet potatoes, can be foods that start to increase your fiber intake gently (10).
Keep in mind that if you intake too quickly or increase insoluble fiber from foods like raw green vegetables, you can exacerbate IBS symptoms in some people (11). If you know you have IBS, talk to your healthcare provider about the best textile strategies for you.

How to get enough fiber
If you are struggling to achieve your daily fiber goals, you may be considering a fiber supplement. They can have a place from time to time, but generally a better idea Get the fiber from Whole Foods According to Myfitnesspal nutritionist Katherine Basbaum. “In addition to fiber, whole foods provide you with a bunch of other healthy nutrients, vitamins and minerals,” she says.
Below is a nutritionist-approved method to increase your fiber intake.
Eat more plant foods
One of the easiest strategies to increase your fiber intake is to prioritize your plants!
You don’t need to eat a plant-based diet or go to a vegan or vegetarian to enjoy the benefits of plants during your diet.
All these whole foods are Fiber All Stars:
- Whole Grains
- fruit
- vegetables
- beans
- nuts
- seed
Pro tips: When it comes to fiber, don’t overlook the seeds! Another myfitnesspal nutritionist, Joanna Greg, particularly likes flaxseeds.
Start your day with textiles
Breakfast can set the tone for your day. Start with a high fiber diet It will help you fill up and stay energized throughout the morning. Usually, eating a low-fiber breakfast can go a long way in helping you increase your fiber intake by adding something.
To add one of these to enhance the fiber in your morning meal:
- Whole grain toast
- Berry smoothie
- Chia seeds
- avocado
- apple
- banana
- oatmeal
Snack Smart
Instead of reaching for chips or crackers, they rarely give them fiber. Choose nuts, seeds, raw vegetables, or hummus to choose a snack. As a nutritionist, I tell people Take at least 3-5 grams of fiber per snack! This could be a Greek yogurt with whole grain toast, peanut butter and bananas sliced on top, or a greek yogurt with berry and chia seeds.
Start small
Increased fiber intake doesn’t need to mean a complete overhaul of your diet. A simple, small swap can have a big result.
Here are some ideas:
- Choose whole grain bread in the store rather than white
- Add beans to soups and salads
- Hummus or Bean Dip Snacks
These small choices will result in a significant increase in fiber intake.
