The Claim

A 5-week daily intake of erythritol or xylitol has no significant effect on liver fat percentage, liver volume, or visceral adipose tissue in adults with obesity.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

In adults with obesity, consuming erythritol or xylitol daily for five weeks does not change the amount of fat in the liver, the size of the liver, or the amount of fat around internal organs.

See the scientific wording

A 5-week daily intake of erythritol or xylitol does not significantly affect liver fat percentage, liver volume, or visceral adipose tissue in adults with obesity, suggesting these sweeteners do not reduce ectopic fat accumulation under these conditions.

Why this might work

When people consume erythritol or xylitol daily, their bodies process these sweeteners without triggering changes in how the liver stores fat or how fat builds up around the organs. The liver keeps processing fats the same way, and fat around the belly does not decrease.

  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

    This study gave obese people daily doses of erythritol or xylitol for five weeks and found their liver and belly fat didn’t go down. So, these sweeteners didn’t help clear harmful fat deposits in this group.
