The Claim

A daily intake of 36 grams of erythritol or 24 grams of xylitol for five weeks has no statistically significant effect on arterial stiffness, retinal vessel diameter, abdominal fat distribution, glucose tolerance, or blood lipid levels in adults with obesity.

Description
1 study reviewed
In plain English

Taking 36 grams of erythritol or 24 grams of xylitol every day for five weeks does not change arterial stiffness, retinal blood vessel size, abdominal fat, blood sugar control, or blood lipid levels in adults with obesity.

See the scientific wording

A 5-week daily intake of 36 grams of erythritol or 24 grams of xylitol has no statistically significant effect on arterial stiffness, retinal vessel diameter, abdominal fat distribution, glucose tolerance, or blood lipid levels in adults with obesity, suggesting these sweeteners do not meaningfully alter these metabolic or vascular parameters under these conditions.

Why this might work

Erythritol and xylitol are absorbed but not metabolized for energy, so they do not trigger insulin release, fat storage, or inflammation. Without these signals, arteries, fat tissue, and blood vessels remain unchanged in structure and function.

  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 36 grams of erythritol or 24 grams of xylitol every day for five weeks didn’t show any changes in their blood sugar, fat around organs, or artery stiffness — meaning these sweeteners didn’t help or hurt those health markers in this study.
