Can you die if you only eat one time a day?

Most likely, you will not die if you only eat once a day. While this isn't a healthy lifestyle, the body can survive on small amounts of food. However, water is more important, and a person will die of dehydration before starvation.

Your body needs a balanced diet to function properly. If you eat once a day, you are unable to take in all the nutrients, calories, and fuel your body needs to perform properly. You may find that you get sick more often, have vitamin deficiencies, have fatigue, and mental distractions.
