According to an article found on Modern Medicine, Gregory L. Austin, M.D., of the University of Colorado in Aurora, conducted a study involving 17 patients with diarrhea-predominant irritable bowel syndrome. After following a two-week standard diet, the participants were then put on a four week very low carbohydrate diet, consisting of only 20 grams of carbohydrates a day.
The abstract shows that of the patients who completed the diet, which totaled 13, all responded with their results. 77% of the participants (10 of the 13) reported adequate relief of symptoms during the low-carb phase of their diet plans. (As someone who suffers from this malady, I can vouch that these results are accurate.) “Pain scores and quality-of-life measures significantly improved. Outcomes were independent of weight loss.” states the author. Their conclusion: “A VLCD provides adequate relief, and improves abdominal pain, stool habits, and quality of life in IBS-D.”
