When it comes to nutrition in bodybuilding circles, it’s usually about calories, macros (proteins, carbs, and fats), and micros (vitamins and minerals). But what about dietary fiber? To what extent does it play a role in achieving the desired body composition?

WHAT IS DIETARY FIBER?

Dietary fiber is an indigestible carbohydrate found primarily in plant foods, such as vegetables, fruits, legumes, potatoes, whole grains, nuts, and seeds. Fiber-rich foods include whole wheat bread, oatmeal, and muesli.

Dietary fiber plays an important role in digestion, bowel movements and the maintenance of healthy intestinal flora.

Eating fiber-rich foods contributes to your health in several ways: cardiovascular, stroke prevention, and diabetes management. In addition, sufficient fiber intake can reduce the risk of certain diseases, such as cardiovascular disease, type 2 diabetes, and colon cancer.

The recommended daily amount of fiber is about 25-35 grams for adults. This is easy to keep track of using a calorie app.

TYPES OF DIETARY FIBER

We can divide dietary fiber into soluble and insoluble.

Soluble fiber dissolves in water and forms a gel-like substance. This helps slow digestion, regulate blood sugar levels, and lower cholesterol. It is found in foods such as oats, beans, tomatoes, apples, and citrus fruits.

Insoluble fiber does not dissolve in water and adds bulk to stool, which promotes regularity and prevents constipation. Good sources include whole grains, nuts, seeds, and vegetables such as carrots, celery, and leafy greens.

DIETARY FIBER AND BODY COMPOSITION

But now the crucial question: do dietary fibers play a role in achieving the desired body composition, i.e. more muscle and less fat? A recent scientific article provides the answer. And yes, fibers are also important for strength athletes. They play a role in:

• intestinal flora health: fiber intake supports the production of short-chain fatty acids, which improve digestion and energy availability;
• recovery and inflammation: certain fibers, including beta-glucans, may help reduce inflammation after exercise;
• fat loss: High-fiber diets can help control appetite and regulate energy intake.

CONCLUSION AND ADVICE

Dietary fiber is important for gut health, inflammation, and metabolism. Strength athletes often follow a high-fiber diet, which can benefit recovery, performance, and fat loss. There are also long-term health benefits.

Make sure you eat at least 25 grams of dietary fiber per day. If you are going to increase your intake, do so gradually.
