depends on BMI, how healthy you are ? might be days or weeks

There are many factors that control how the human body can resist the lack of water and food.

 

The most important air .. and physical infrastructure .. .. old health status ... energy consumption and water stress or excessive anxiety ..

 

Food is first:

If the disappearance of first loses and consumes energy

It is in your body first, sugars and fats, and most recently, a protein component of many organs, muscles ..

 

But how your body resists for lack of food ..

 

Better is that gets you and you are in the proper temperature Joe ..

If the temperature dropped consumed energy

 If the rose water and energy consumed ..

 

But how long you can live without food .. In fact, if you are in good health for ((8 weeks)) if the availability of water and also vary from one person to another, and as we know that the political prisoners have lived longer and shorter than this period and lived Gandhi 21 days the son of the seventy

 

The water:

 

We know that 65% of the human body is water is being blood and thus helps the transfer of oxygen, food and salt to the rest of the body and into the cells, which is important for the muscles and joints, which is important in the digestion and absorption. If the disappearance of the water affected and collapsed all of these processes.

 

 How much you need from time to reach for it ..

 

At temperatures and good conditions of (( 3-5 days)) may increase a day or less depending on your health, but if you worked hard and has taken pains to yourself and made a double effort, or at very high temperatures may not need more than a few hours ..

Without eating food a person can survive for 2-3 weeks  depending upon body reserves of nutrients but water is essentially required for most of the metabolic activities and water do not store for longer period of time in the human body so in moderate temperature without water you may survive up to 2-3  days only.

three weeks The human body needs food and water to survive. A human can go for more than three weeks without food (Mahatma Gandhi survived 21 days of complete starvation), but water is a different story. At least 60% of the adult body is made of it and every living cell in the body needs it to keep functioning.

The duration of survival without food is greatly influenced by factors such as body weight, genetic variation, other health considerations and, most importantly, the presence or absence of dehydration.
