The Claim

A 5-week daily intake of erythritol or xylitol has no significant effect on fasting glucose, insulin, or HOMA-IR levels in adults with obesity.

Description
1 study reviewed
In plain English

Taking erythritol or xylitol every day for five weeks does not change fasting blood sugar, insulin levels, or insulin resistance in adults with obesity.

See the scientific wording

A 5-week daily intake of erythritol or xylitol does not significantly alter fasting glucose, insulin, or HOMA-IR in adults with obesity, indicating these sweeteners do not improve or impair glucose metabolism under these conditions.

Why this might work

When people eat erythritol or xylitol, their bodies do not trigger the liver to change how it makes or releases sugar, and the pancreas does not adjust insulin production. As a result, blood sugar and insulin levels stay the same.

  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 people with obesity either erythritol or xylitol every day for five weeks and found their blood sugar, insulin, and insulin resistance didn’t change — meaning these sweeteners didn’t help or hurt their glucose control.
