how long can the human body last without water or food
In addition, humans can actually survive crazy amounts of time without any type of food, liquid or otherwise, as long as they still have adequate water. Depending on health and body size, it's estimated that a healthy person can last between 30 and 40 days without eating a single bite. In one extreme case, a 456-pound man lasted an astonishing 382 days without eating any food, solid or liquid, ABC Science reported. Over the course of his year of starvation, the man dropped down to 180 pounds and was able to keep the weight off for five years.
