The Claim

Ingestion of beverages containing at least 1.5% glycerol results in smaller reductions in body mass over 210 minutes post-consumption compared to placebo in healthy, active adults, indicating enhanced fluid retention.

Source: A randomized trial modeling the effects of solutions with low to moderate glycerol and sodium concentrations on fluid balance in healthy, active adults.

What the research says

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

Drinking beverages with at least 1.5% glycerol leads to less loss of body mass over 210 minutes after consumption compared to drinking a placebo, which indicates greater fluid retention in the body.

See the scientific wording

Ingestion of beverages containing at least 1.5% glycerol improves fluid balance in healthy, active adults, as measured by smaller reductions in body mass over 210 minutes post-consumption compared to placebo, indicating enhanced fluid retention.

Why this might work

When glycerol is consumed, it enters the bloodstream and makes the blood slightly saltier, which signals the kidneys to hold onto more water instead of flushing it out as urine. This keeps more fluid in the body, so less weight is lost over time.

  1. Study: A randomized trial modeling the effects of solutions with low to moderate glycerol and sodium concentrations on fluid balance in healthy, active adults.

    Drinking a beverage with at least 1.5% glycerol helped people keep more water in their bodies than drinking plain water, so they lost less body weight over 3.5 hours. It’s like glycerol acts as a sponge to hold onto fluid longer.
