Energy balance

Substituting low-calorie sweetened (LCS) beverages for sugar-sweetened beverages (SSBs) is an effective strategy to reduce energy intake and promote weight loss in adults, particularly habitual SSB consumers.

If you drink sugary sodas regularly, switching to diet or zero-sugar versions is a scientifically supported way to cut calories and lose weight. It works best if you use it to replace sugary drinks, not to add on top of them. If you have diabetes, this can help manage blood sugar spikes, but you should still prioritize water when possible.
