The Claim

In C57BL/6 male mice on a regular chow diet, chronic consumption of ace K, aspartame, sucralose, saccharin, and Reb M is associated with no significant differences in body weight, fat mass, lean mass, or total caloric intake compared to water controls.

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.

In plain English

When male mice of a common lab breed ate food with artificial sweeteners instead of plain water for a long time, they didn’t gain more or less weight, fat, or muscle, and they ate about the same amount of food as mice that only drank water.

See the scientific wording

In C57BL/6 male mice on a regular chow diet, chronic consumption of all tested NNSs (ace K, aspartame, sucralose, saccharin, Reb M) was associated with no significant differences in body weight, fat mass, lean mass, or total caloric intake compared to water controls.

What the research says

1 study
  1. Study: Long-term metabolic effects of non-nutritive sweeteners

    The study gave mice the same artificial sweeteners as mentioned in the claim and found they didn’t gain more weight, fat, or eat more than mice drinking plain water — so the claim is correct.
