A diet revolving around high fiber low carb has lots of greens, fruits, and some reputable nuts. A well-constructed low carb diet will deliver the daily recommended amounts of fiber for healthy digestion.

Why Fiber?

The body needs fiber but it does not digest it. Fiber comes in two varieties, soluble and insoluble, whereby most plant sources contain both types. The soluble fiber turns into a gel, therefore, slows down digestion by lowering the levels of blood glucose and cholesterol. The insoluble fiber remains the same all through, but functions in making the waste softer and heavier for easy elimination.

Neither type of fiber is absorbed into the body, but skipping on your daily dose will result in constipation and makes waster elimination an uncomfortable and painful process. Eating inadequate amount of fiber can result in difficulty controlling blood sugar and appetite as fiber lowers the speed of digestion and makes you feel full.

Overdoing it has its demerits, including food moving through the intestines too fast and leaving little time for the nutrients and minerals to be absorbed. It also causes uncomfortable bloating, gas, and cramping especially if you dramatically increase fiber intake overnight.

Is Fiber Carbohydrate?

Even though fiber is a carbohydrate, it is of a special type that the human body cannot digest. The human digestive system cannot dismantle fiber into simple sugar the way it does regular carbohydrates. Since it passes the digestive tract without being digested, fiber acts as a regulator of blood sugar levels and keeps hunger at bay.

The only way fiber provides calories is as a product of fermentation in the colon but not as glucose. By creating a feeling of satiety, fiber helps prevent weight gain and helps moderate the effects of usable carbohydrates in the bloodstream. It prevents hypertension and maintains a healthy level of LDL cholesterol.

For a healthy lifestyle, it is recommended that you take 20-30 grams of fiber daily. Most people, however, survive on about 15 grams a day due to bad meal planning or from not being aware of the right sources of dietary fiber. The best sources of fiber include fresh fruits, vegetables, legumes, nuts, and whole grains.
