Let’s be honest: most of us would rather drink something that feels like a spa treatment than plain water from the sink. Psychologically, cucumber water makes you feel bougie, which might trick you into drinking more. And drinking more water does help with weight loss—because it fills you up, boosts metabolism slightly, and stops your brain from confusing thirst with hunger.
One study found that drinking 500ml of water before meals helped people eat about 75 fewer calories per meal. That’s not a cucumber—that’s just good old H2O. But if adding a slice of cucumber makes you drink those 500ml, then by all means, go full spa-rat. Just don’t expect the cucumber to do the heavy lifting.
