much longer can it be?
Consuming food and water is necessary for maintaining human
life. To function correctly, your body requires both hydrations from water and
energy from dietary sources, with such a diversified diet and enough water
consumed each day, the different systems in your body function at their best.
However, our bodies can also go for days without water. Due
to changes in our metabolism needs, we might go days or even weeks without
Starvation is often referred to as the prolonged deprivation
of food and drink. After a day or two without food or drink, your body may
start to starve. At that point, the body begins to change its functioning to
consume less energy. Starvation eventually results in death.
How long you can go without food is not something that can
be determined with absolute certainty. Because it is currently thought to be
immoral to investigate starvation in human patients, there is a dearth of
scientific research on the subject.
Several studies look at both more recent instances of famine in the real world and older surveys on the subject. These events include hunger strikes, fasts observed for religious reasons, and others.
These investigations have produced the following conclusions
- According to a study published in Archiv Fur Kriminologie, the body can go 8 to 21 days without food or water, and up to two months if it has access to enough water to drink.
- Hunger strikes in the modern era have shed light on starvation. In research published in the British Medical Journal, some hunger strikes that lasted between 21 and 40 days were mentioned. Due to the individuals' severe, perhaps fatal symptoms, these hunger strikes were called off.
- Your body mass index (BMI) scale appears to have a "minimum" value for survival. Men with a BMI of less than 13 and women with a BMI of less than 11 are unable to sustain life, claims the journal Nutrition.
- According to a British Medical Journal article reliable Source, people who are of average weight will lose more of their body weight and muscle mass during the first three days of starvation than people who are obese.
- Women can endure fasting longer due to their physical composition, claims the journal Nutrition.
How is that
Many of us find it hard to imagine being able to go days or
weeks without food or drink. After all, many of us get irritated and lethargic
after a daylong fast or simply a few hours without food or water.
If you go on a brief fast or are without food and water for
extended periods of time, your body really regulates itself. This makes it
possible for people to observe fasts for their religions and even experiment
with "fasting" diets such as the eat-stop-eat strategy without causing
their bodies permanent harm.
Your body changes how it functions after around eight hours
without food. It operates as though you were eating often prior to that.
Someone's body converts food into glucose in typical
conditions. The body receives energy from glucose.
Your body's glucose reserves are drained after 8 to 12 hours
without eating. Your body will start converting the glycogen in your muscles,
liver, and liver into glucose.
When your body runs out of glucose and glycogen, it will
start turning to amino acids for energy. Your muscles will be affected by this
process, which can support your body for around three days of famine. Trusted

The body starts to rely on fat reserves to produce ketones
for energy, a condition known as ketosis, in order to prevent severe muscle
loss. During this time, you will significantly lose weight. The increased fat
content of women's bodies is one of the reasons they can endure fasting for
longer than males. In times of hunger, females also are better able to retain
protein or lean muscle mass than males.
An individual can normally endure famine for a longer period
of time if there are greater fat reserves available. Since there is only one
fuel source left in the body once all of the fat stores have been fully
digested, the body then switches back to breaking down muscle for energy.
When your body used its muscle stores for energy throughout
the stage of famine, you'll start to feel significant unfavorable effects. According
to a study published in the British Medical JournalTrusted Source, people who
are on a hunger strike should indeed be regularly watched for severe
starvation-related adverse effects after dropping 10% of their body weight.
Additionally, it states that when a person loses 18 percent of their body
weight, very significant problems will manifest.
does drinking water change this?
Unless you're able to drink a sufficient amount of water,
you're considerably more likely to be able to endure weeks or even months of
famine. Your body can replace food and fluid with significantly more of its
stored energy. Without adequate fluids, your kidney function will deteriorate
within a few days.
One source claims that people who are close to death can go
10 to 14 days without food or water. Although they are less frequent, certain
periods of survival have been observed. Remember that bedridden persons don't
expend much energy. A healthy, active person would presumably pass away much
According to one study that examined hunger strikes, in
order to endure starvation for a longer amount of time, a person must consume
at least 1.5 liters of water daily. In order to support renal function, the study
also recommended adding a half teaspoon of salt to your water every day.
eating's negative consequences and hazards
Living lack access to water and food can be harmful to your body. Despite the fact that your body can survive for days or even weeks without food or drink, many of its systems will start to degenerate.
Among the consequences of malnutrition are:
- Blood pressure drop
- Slowing heart rate
- Thyroid malfunction
- Abdominal pain
- Low potassium
- Body temperature instability
- Post-traumatic stress or depression
- Heart attack
- Organ failure
People who have been severely malnourished for a while
cannot immediately start eating normally. To prevent negative reactions, also
referred to as refeeding syndrome, the body must be very gradually eased back into
- Heart problems
- Neurological disorders
- Tissue swelling throughout the body
During starvation, eating can be resumed under a doctor's
supervision and may entail consuming lactose-free meals, boiling vegetables,
and a low-protein, low-sugar diet.
Without adequate food and water, human beings may survive
for days or even weeks. This is not to argue that going off food for a long
time is healthy or something that you should do.
Without food or water, the body can survive for a week or
two, and if you drink water, it can even last longer. To prevent refeeding
syndrome, those who suffer hunger must be closely watched by a physician while
they recover their health after the period without food.
