Without any food, humans usually die in around 2 months. [9] There was a case when someone survived over a year (382 days) under medical supervision. [10] Lean people can usually survive with a loss of up to 18% of their body mass; obese people can tolerate more, possibly over 20%. Females may survive longer than males due to their higher body ...
Bone, tendon, and skin can survive as long as 8 to 12 hours. [5] The brain, however, appears to accumulate ischemic injury faster than any other organ. Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare.

The human body has 78 organs and each one performs a variety of important functions. While it's possible to live without organs like the appendix, gallbladder, or spleen, several of our organs are ...
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
At present, there is no drug or device that can reverse organ failure that has been judged by the health care team to be medically and/or surgically irreversible (organ function can recover, at least to a degree, in patients whose organs are very dysfunctional, where the patient has not died; [citation needed] and some organs, like the liver or ...
How long someone can survive without food depends on various aspects, such as their age, weight genetics, health and hydration level.
Many organs can be extracted, and many lives can be saved by one body. The bodies are generally those of organ donors , who have either given first-person consent to become an organ donor, presumptive consent by not explicitly declining to donate [ 10 ] or whose legal next-of-kin makes the decision to donate.
