The Claim

Daily consumption of 24 grams of xylitol for five weeks is associated with a higher incidence of loose stools compared to consumption of 36 grams of erythritol or no sweetener in adults with obesity.

In plain English

Adults with obesity who consume 24 grams of xylitol daily for five weeks experience more loose stools than those who consume 36 grams of erythritol or no sweetener.

See the scientific wording

Daily consumption of 24 grams of xylitol for five weeks is associated with a higher incidence of loose stools compared to 36 grams of erythritol or no sweetener in adults with obesity, indicating xylitol may cause mild gastrointestinal discomfort at this dose.

Why this might work

Xylitol pulls water into the intestines and is broken down by gut bacteria, which produces gas and acids that make the stool loose and watery.

  1. Study: Effects of a 5-week intake of erythritol and xylitol on vascular function, abdominal fat and glucose tolerance in humans with obesity: a pilot trial

    People with obesity who ate 24 grams of xylitol every day for five weeks had more loose stools than those who ate 36 grams of erythritol or nothing at all, so xylitol can cause mild stomach issues at this dose.
