Is it normal to not eat for a day?
Going a day without eating can happen now and then, especially if you’re sick, stressed, busy, or fasting. If it’s happening often, feels hard to control, or leaves you weak or dizzy, it’s worth paying attention to.
Yes, it can happen. Stress, illness, a disrupted schedule, or simply not feeling hungry can make you miss meals, and some people choose to fast. One day without food isn’t automatically a problem for most otherwise healthy adults; drinking fluids matters, too.
People have different views on intentional fasting, and it isn’t a good fit for everyone. If you have a condition or take medication affected by meals, or if you’re pregnant, check with a health professional before fasting. If you keep going a day without eating, can’t manage to eat, or feel faint or unwell, talk with a health professional about what’s going on.
