How long can a human being live without food?

Question

How long can a human being live without food?

Answer 1

Babies manage to last a year or two on just drink.  Milk.  So I suppose it's what's in the drink, that matters.  If it contains carbohydrates, proteins, fats, vitamins, mineral salts and water, then a long time.  Also consider people living on a "drip" in hospital.

Answer 2

It depends on the person and how big they are. Since you start to use your fatty cell as your reserve fat ( basically your stomach it eating its self.) But, every human needs water to survive. 3 day rule, if you don't have water within 3 days you die of dyhration.  

Answer 3

It depends on the person's energy stores.  There is no definitive answer, but it's been estimated that a person of normal body weight can live off of their fat stores for 30 - 60 days.  Water, however is a completely different story.  I think it's 3 days maximum that a person can go without water.  

Answer 4

it depends on their body fat. a bigger person could last longer than a person of normal body weight and a person with normal body weight and a bigger person can both live longer than a rather skinny person. however water is different. im not exactly sure how long u can live without water but i DO know its possible to live with out water for up to a week. my grandpa had cancer in the hospital his daughters took away all food and water from him so he just sat there. for 1 week he did get really weak that last week but he made it EXACTLY 1 week. so that 3 days is just bullsh*t
