In general, it is likely that a person could survive between 1 and 2 months without food. As many different factors influence the length of time that the body can last without food, this period will vary among individuals.
How long human beings can go without food is an open question. Estimates indicate that starving people become weak in 30 to 50 days and die in 43 to 70 days. Individual factors including sex, age, starting weight, and water intake all play a role in how long someone can live without food.
As a result of discontinuing eating, patients can die in as early as a few days. For most people, this period without food usually lasts about 10 days, but in rare instances, it can last several weeks.
Experts believe it is possible for the human body to survive without food for up to two months.
There is a long and short answer to the question, “How much weight can you lose in a week?” Sure, if you stop eating altogether and amp up exercise, you can lose up to 30 pounds in a week.

Self-Starvation Effects
Researchers say we can go about 70 days without food, but that doesn't mean it's healthy [2]. Most people with anorexia struggle with their condition for years as they wax and wane between starving and eating healthfully. Typically, starvation moves in three phases [2]:
The symptoms of starvation show up in three stages. Phase one and two can show up in anyone that skips meals, diets, and goes through fasting. Phase three is more severe, can be fatal, and results from long-term starvation.
Fat people would only be able to survive for longer if they had enough vital water-soluble B vitamins in their system to help metabolise fat stores. So it is possible that a person could die of starvation and still be fat.
However, people who have voluntarily stopped eating to participate in hunger strikes have died after 45–61 days , which suggests that a person would be unlikely to survive for 3 months. The body needs the nutrients in food to survive.
According to one study, you cannot survive for more than 8 to 21 days without food and water. Individuals on their deathbeds who use little energy may only last a few days or weeks without food or water. Water is far more important to the human body than food.
Generally, it appears as though humans can survive without any food for 30-40 days, as long as they are properly hydrated. Severe symptoms of starvation begin around 35-40 days, and as highlighted by the hunger strikers of the Maze Prison in Belfast in the 1980s, death can occur at around 45 to 61 days.
In general terms, the human body can go two to three days without water and, it is often said in survival guides, 30 to 40 days without food of any kind. (Many of these guides also discourage people from scavenging for wild plants or shrubs because of the adverse effects these can have.)
Your body can meet the majority of your calorie requirements from stored fat, but total starvation is fatal in 8-12 weeks, regardless of initial body weight. Within one or two days of your last meal, your body will have exhausted all the glycogen stored in the liver and muscles.
The body attempts to protect the brain, says Zucker, by shutting down the most metabolically intense functions first, like digestion, resulting in diarrhea. "The brain is relatively protected, but eventually we worry about neuronal death and brain matter loss," she says.
The lack of pain is part of a protective mechanism developed over millions of years, Sullivan said. After 24 hours without food, “the body goes into a different mode, and you're not hungry anymore,” he said. “Total starvation is not painful or uncomfortable at all.
You could be malnourished if: you unintentionally lose 5 to 10% of your body weight within 3 to 6 months. your body mass index (BMI) is under 18.5 (although a person with a BMI under 20 could also be at risk) – use the BMI calculator to work out your BMI. clothes, belts and jewellery seem to become looser over time.
There are also different tiers of anorexia based on BMI ranging from mild (<17.5), moderate (16-16.99), and severe (15-15.99), to extreme (<15). A BMI below 13.5 can lead to organ failure, while a BMI below 12 can be life-threatening.
An eating disorder, such as anorexia nervosa, does not mean you will always be thin. One of the most common and dangerous myths about eating disorders is that everyone who has one is thin. Anorexia nervosa and other eating disorders are both mental and physical illnesses that can affect people of all sizes.
After 32 hours you will see significant weight loss, however, this is mostly part of losing water from depleting carbohydrates as well as fat loss. Once you get to 3 days of fasting, the process of enhanced immunity, autophagy and reduction in inflammation continues. But the cons start to outweigh the pros.
Jani was commonly known as Mataji ("[a manifestation of] The Great Mother"). Jani believed that the Goddess provided him with water which dropped down through a hole in his palate, which allowed him to live without food or drink. Since the 1970s, Jani had lived as a hermit in a cave in the forest in Gujarat.
