I need to know how long a person can go without food.

The answer to this question will depend on the individual, their health and fitness levels, as well as the type of food they are eating. Generally, it is recommended that adults consume between 2,000-2,500 calories per day in order to maintain a healthy weight. If you have specific concerns about your own diet or nutrition needs, I recommend speaking with a healthcare professional such as a registered dietician.
