Stopping or reducing dietary fiber intake reduces constipation and its associated symptoms
Abstract
AIM: To investigate the effect of reducing dietary fiber on patients with idiopathic constipation.
METHODS: Sixty-three cases of idiopathic constipation presenting between May 2008 and May 2010 were enrolled into the study after colonoscopy excluded an organic cause of the constipation. Patients with previous colon surgery or a medical cause of their constipation were excluded. All patients were given an explanation on the role of fiber in the gastrointestinal tract. They were then asked to go on a no fiber diet for 2 wk. Thereafter, they were asked to reduce the amount of dietary fiber intake to a level that they found acceptable. Dietary fiber intake, symptoms of constipation, difficulty in evacuation of stools, anal bleeding, abdominal bloating or abdominal pain were recorded at 1 and 6 mo.
RESULTS: The median age of the patients (16 male, 47 female) was 47 years (range, 20-80 years). At 6 mo, 41 patients remained on a no fiber diet, 16 on a reduced fiber diet, and 6 resumed their high fiber diet for religious or personal reasons. Patients who stopped or reduced dietary fiber had significant improvement in their symptoms while those who continued on a high fiber diet had no change. Of those who stopped fiber completely, the bowel frequency increased from one motion in 3.75 d (± 1.59 d) to one motion in 1.0 d (± 0.0 d) (P < 0.001); those with reduced fiber intake had increased bowel frequency from a mean of one motion per 4.19 d (± 2.09 d) to one motion per 1.9 d (± 1.21 d) on a reduced fiber diet (P < 0.001); those who remained on a high fiber diet continued to have a mean of one motion per 6.83 d (± 1.03 d) before and after consultation. For no fiber, reduced fiber and high fiber groups, respectively, symptoms of bloating were present in 0%, 31.3% and 100% (P < 0.001) and straining to pass stools occurred in 0%, 43.8% and 100% (P < 0.001).
CONCLUSION: Idiopathic constipation and its associated symptoms can be effectively reduced by stopping or even lowering the intake of dietary fiber.

PULP FICTION: The Truth about Fiber
The word fiber conjures up wholesome, earthy-crunchy images of squeaky clean intestines and free-flowing coronary arteries. Yet fiber is not a nutrient at all, and is not absorbed by our bodies. What is fiber? What is the difference between soluble and insoluble fiber, is it really healthy for us, and do we even need to eat it?

Fiber and Colon Health On A Well-Formulated Ketogenic Diet: New Insights Question Its Role As An Unconditional Requirement
To be specific, we are not challenging fiber’s important role in colon health—along with an optimized microbiome—in the context of a diet whose combined total of carbohydrate and protein is high enough to suppress nutritional ketosis. However, cultural, historical, and now strong biochemical evidence indicates that many of the benefits of fiber fermentation in the colon can be replaced by the normal physiological production of BOHB by the liver during a well-formulated ketogenic diet.
