Humans need food to live.food is what sustain the body. However, some researchers say humans can survive without food for up to 2 months.

Humans really can survive without food or in liquid form. As long as they still have enough water this can last, depending on health and body size.

Report has it that healthy people can stay up 30 to 40 days without eating a single bite of food.

And in history we have read from Bible how Jesus, Moses and Elijah stayed forty

days without eating or drinking anything.

Also the human body has an innert regulatory mechanism to provide energy for the cells to function should food stop coming from external sources.

It does this by using up the stored glucose and it continues without food,it will convert protein into amino acid all in the bid of providing energy.

The liver and muscles can store glycogen which is then converted to glucose. When glucose in the body runs out, fat can be converted into energy supply. If the fat runs out, the body will take energy from the protein from the muscle.
