The Claim

In overweight adults without diabetes, consumption of saccharin at the maximum acceptable daily intake for three months results in no measurable changes in fasting plasma glucose, fasting C-peptide, or HOMA-IR.

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

In overweight adults without diabetes, taking saccharin at the highest approved daily dose for three months does not change fasting blood sugar, insulin levels, or insulin resistance measures.

See the scientific wording

In overweight adults without diabetes, saccharin consumption at the maximum acceptable daily intake for three months does not lead to measurable changes in fasting plasma glucose, fasting C-peptide, or HOMA-IR, indicating no significant effect on basal glucose metabolism or insulin secretion.

Why this might work

The liver keeps making the same amount of glucose, and the pancreas releases the same amount of insulin, so blood sugar stays steady even when saccharin is consumed daily.

  1. Study: Effects of saccharin on insulin sensitivity in adult, overweight individuals without diabetes: a real-world pilot study

    This study gave overweight people saccharin every day for three months and found no change in how well their bodies used insulin or their blood sugar levels, meaning saccharin didn't mess with their metabolism.
