See the scientific wording

Among adults with high baseline trunk fat mass, replacing sugar-sweetened beverages with either artificially sweetened or unsweetened beverages for 12 months reduces weight gain compared to continuing sugar-sweetened beverage consumption, with a mean difference of approximately 4.2 kg between groups.

Why this might work

When people with excess belly fat stop drinking sugary drinks and switch to drinks without sugar or with artificial sweeteners, they consume fewer calories. This lowers insulin levels after meals, which stops the body from storing more fat and allows it to burn existing fat. Over time, drinking unsweetened beverages also makes sweet tastes less appealing, so people naturally eat less sugary food. Together, these changes cause the body to lose weight or gain less weight.
