Reply to comment by WeirdlyTallDwarf in ELI5: why do our bodies randomly act like we haven’t had water in days and that we need to chug a bunch randomly? by Serratedlily

No it's radically different. If you haven't eaten enough food your body will burn fat for energy. But your body has no alternative hydration source. You can go a month easy without food, you cannot go more than a few days without water and still live. And you cannot go a few hours of being lightly dehydrated without your body's performance falling below optimal
