Stop Ignoring Fiber!
When it comes to nutrition, protein gets all the attention. But there’s another important nutrient that deserves more attention: fiber!
Fiber plays an important role in overall health. It can also be especially helpful when your goal is to build muscle, lose body fat, or simply feel better day to day.
So, what exactly is fiber, and why should you care about it?
What Is Fiber?
Fiber is one of the most overlooked nutrients. It’s a type of carbohydrate that your body doesn’t fully digest. Instead of being broken down and used primarily for energy, it moves through your digestive system and does a bunch of important things along the way.
Fiber is generally broken down into two categories, soluble & insoluble, but both types are important. Most people benefit from eating a variety of plant foods, such as fruits, vegetables, whole grains, beans, lentils, nuts, and seeds rather than worrying about specific fiber types.
Fiber & General Health
Fiber is probably best known for supporting digestion, but it does a lot more than that!
Getting enough fiber is linked to:
→ Better gut health (influences immune function, mood, and recovery)
→ More stable blood sugar levels
→ More stable energy levels
→ Improved cholesterol levels
→ Lower risk of several chronic diseases
Fiber & Muscle Gain
When people think about building muscle, they usually focus only on protein. Protein absolutely matters, but fiber still plays an important role.
Fiber helps:
→ better nutrient absorption, which can translate to more efficient recovery and improved performance
→ slow digestion and help promote more stable blood sugar levels, which may help you maintain energy throughout the day and around your workouts.
→ prevents insulin spikes, allowing the body to direct nutrients towards muscle cells vs storing excess energy as fat
→ reduce inflammation, helping you recover faster and reducing injury risk
Fiber & Fat Loss
One of the biggest advantages is satiety. High-fiber foods tend to make meals more filling, which can make it easier to stick to a calorie deficit without feeling hungry all the time.
Meals higher in fiber often:
→ are more filling, controlling appetite and preventing overeating
→ help stabilize blood sugar, preventing certain triggers of food cravings
→ some types of fiber can also reduce the absorption of certain nutrients, including a small amount of dietary fat.
How Much Fiber Should You Aim For?
General recommendations are:
- Women 18-50: 25g/day
- Men 18-50: 38g/day
- Women 50+: 21g/day
- Men 50+: 30g/day
Easy Ways To Eat More Fiber
- Add berries or chia seeds to your breakfast
- Swap refined grains (like white bread, rice, and pasta) for whole grain versions.
- Include a vegetable at at least two meals a day
- Add beans, lentils, or other legumes to meals whenever you can.
- Snack on fruits, nuts, or popcorn instead of ultra processed snacks.
- Consider a fiber supplement if needed. Whole foods are the best source of fiber, but if you’re consistently falling short, a supplement like psyllium husk can be an effective way to help meet your daily needs.
Important: Increase Fiber Slowly
If your current fiber intake is low, don’t suddenly jump from 10 grams/day to 40 grams/day. Your digestive system will not take it well.
Increase fiber gradually and make sure you’re drinking enough water as well. Fiber and hydration work together and increasing one without the other can lead to digestive discomfort.
Fiber may not be the most exciting nutrient in your diet, but it is an important one.
It supports digestion, helps keep meals satisfying, contributes to overall health, and can make it easier to maintain a balanced diet whether your goal is building muscle, losing body fat, or simply feeling your best.
And your digestive system will thank you for it!
