The Effects of Hunger on the Human Body and Mind
Transcript of The Effects of Hunger on the Human Body and Mind
-more than immediate suffering
-affects mood, focus, sense of physical well-being
-is a dual body-mind experience that
-has same deteriorating effects on every human
Physical Effects of Hunger:
- visual disturbances or impaired vision; strange eye movements (vitamin A deficiency)
- bleeding gums & decaying teeth (calcium deficiency)
- skin dries out and flake (hydration and vitamin A deficiency)
- hair loss
- decrease in heart rate and oxygen levels = shortness of breath; makes it difficult to perform physical activity (calcium, iron, protein and Vitamin B deficiency)
Physical Effects of Hunger (cont.):
- disorder in intestinal tract, kidneys and livers = vomiting (fiber deficiency)
- bones become fragile (calcium deficiency)
- nerves in hands & feet break down; loss of feeling in hands and feet (vitamin E deficiency)
- muscles weaken & shrink; aching of joints and muscles (protein deficiency)
- weakening of immune system
->comma & death
Mental Effects of Hunger:
- learning & concentration difficulties
- from early age: reduced intelligence, anxiety, psychiatric issues and cognitive impairment in the long term
- loss of control and feelings
“My head was emptying and emptying, and in the end it sat light and void on my shoulders. I percieved this gaping emptiness in my head with my whole body, I felt hollowed out from top to toe.”
- behavior & pathway changes; decision making; perception of risk
different behavior in novel
- flys moving towards carbon dioxide
- predator only hunts more dangerous prey when it is close to starvation
- hungry people take more financial risks than their sated colleagues
-different neural circuits process environmental signals depending on the state of satiation
“I suffered no pain, my hunger had taken the edge off; instead I felt pleasantly empty, untouched by everything around me and happy to be unseen by all. I put my legs up on the bench and leaned back, the best way to feel the true well-being of seclusion. There wasn't a cloud in my mind, nor did I feel any discomfort, and I hadn't a single unfulfilled desire or craving as far as my thought could reach. I lay with open eyes in a state of utter absence from myself and felt deliciously out of it.”
- like character
- brainy tricks
- incredible sharp senses
“Nothing escaped my eyes. I was sharp and my brain was very much alive, everything poured in toward me with a staggering distinctness.”
- interested in things relating to food; dreaming of cannibalism
- active state; inspiration; desire to work & move
- ending a hunger strike gradually (lacking digestive enzyme); vomiting
"We're all designed to be experts at dealing with hunger."
"Hunger is not a disease, it's a skill the human body has."
~ Joachim Gardemann
- evolution has prepared humans to survive 2-3 months without food & enough water
- every organ shrinks to half its size; brain shrinks by 2-4%
- body does everything possible to preserve the brain
- after 8-10 days of starvation, the body switches to an energy-saving regime; similar to hibernation
- male and female brains react differently
-explains physical decline before mental
“It was not my intention to collapse; no, I would die standing.”
-biological (need), learned (clock) & cognitive (colors)
- controlled by physiology & psychology (eating to satisfy physiology & psychology need)
- environmental factors influence hunger, including the availability of rich foods, taste preferences, habits, memory, stress & cultural attitudes
"If only one had something to eat, just a little, on such a clear day!"

Brain Above All:
Sensation of Hunger:
How is it possible to neglect the effects of hunger on the body through a strong mental determination (as did the character in Hunger)?
