If you’re looking for the rest of that claim, a more accurate version would be:
“Did you know that drinking water on an empty stomach can help you rehydrate after sleep, but it isn’t a miracle detox or a proven way to dramatically boost metabolism?”
Drinking water when you wake up is perfectly reasonable, especially if you’re thirsty. But there’s no strong evidence that drinking it specifically on an empty stomach provides special health benefits compared with drinking water at other times.
If you’re asking about a particular claim—such as weight loss, digestion, blood pressure, or “detoxing”—tell me which one and I’ll explain what the evidence says.
