The Claim

Replacing sugar-sweetened beverages with unsweetened beverages for 12 months results in a greater reduction in sweet taste preference, as measured by the concentration of sucrose perceived as the favorite sweetness level, compared to replacing them with artificially sweetened beverages.

Cause and effect

In plain English

After 12 months, people who switched from sugary drinks to unsweetened drinks preferred less sugar in their drinks than those who switched to drinks with artificial sweeteners.

See the scientific wording

Replacing sugar-sweetened beverages with unsweetened beverages for 12 months reduces sweet taste preference more than replacing them with artificially sweetened beverages, as evidenced by a greater decrease in the concentration of sucrose perceived as the favorite sweetness level (−2.3% vs. −1.1% m/v).

Why this might work

When people stop drinking sweetened beverages and drink only plain water, their taste buds and brain gradually become less sensitive to sweetness. This causes them to prefer much less sugar in their food and drinks because their body no longer expects or craves strong sweet flavors.
