When climate activist Sonam Wangchuk embarked on a hunger strike at the Chief Justice's protest, losing 8.2 kilograms became a stark reminder of how rapidly the human body responds to complete food deprivation. While hunger strikes have long been used as tools of peaceful protest across India and the world, the physiological consequences can be severe and, in some cases, life-threatening.
What Happens to Your Body During a Hunger Strike
The human body is remarkably adaptable, but it responds to starvation through a series of predictable stages. Within the first 24-48 hours, the body exhausts its readily available glucose stores from the liver. After this point, it begins breaking down fat reserves for energy through a process called ketosis.
However, when fat stores become depleted or insufficient, the body starts consuming its own muscle tissue, including the heart muscle. This is where hunger strikes become particularly dangerous. The weight loss experienced during extended fasting isn't just fat – it includes water, muscle mass, and essential tissues.
The Timeline of Starvation
During the first week of a hunger strike, individuals typically experience intense hunger pangs, weakness, dizziness, and difficulty concentrating. The body also begins conserving energy by slowing metabolic processes, leading to decreased body temperature and lethargy.
Between weeks two and three, the hunger sensation often diminishes as the body fully enters starvation mode. However, this is when serious complications begin emerging. Electrolyte imbalances can cause irregular heartbeats, muscle cramps, and confusion. The immune system weakens significantly, making the person vulnerable to infections.
Critical Health Risks
Prolonged food deprivation carries numerous health risks that extend well beyond simple weight loss. The cardiovascular system becomes compromised as the heart muscle weakens. Blood pressure drops, and the risk of cardiac arrest increases substantially after three weeks without food.
Kidney function deteriorates as the body struggles to maintain proper fluid and electrolyte balance. Liver function may also decline. The digestive system essentially shuts down, which can create complications when food is eventually reintroduced – a phenomenon known as refeeding syndrome that can itself be fatal if not managed carefully.
Neurological and Psychological Effects
The brain, which typically consumes about 20% of the body's energy, suffers during prolonged fasting. Cognitive function declines, including memory, attention span, and decision-making abilities. Some hunger strikers report experiencing hallucinations, mood swings, and depression as the fast continues.
Vitamin and mineral deficiencies develop rapidly, particularly of B vitamins, which are crucial for neurological function. Thiamine deficiency can lead to Wernicke's encephalopathy, a serious neurological condition.
Why Activists Choose This Path
Despite the severe health risks, hunger strikes remain a powerful form of non-violent protest in India, following in the tradition of Mahatma Gandhi's fasts for social and political causes. Activists view their physical suffering as both a personal sacrifice and a public statement that draws attention to their cause.
The dramatic visual of someone willing to risk their life for a principle can galvanize public opinion and pressure authorities in ways that other protest methods cannot.
Medical Monitoring and Intervention
When public figures undertake hunger strikes, medical professionals often monitor their condition closely. Doctors track vital signs, blood work, and organ function. They may insist on supplementation with electrolytes and vitamins to prevent the most severe complications, though strikers sometimes refuse even these interventions.
The decision of when to forcibly intervene medically or legally becomes ethically complex. Authorities must balance respecting an individual's right to protest with the duty to preserve life.
Recovery After Breaking a Fast
Once a hunger strike ends, the recovery process must be managed carefully. Reintroducing food too quickly can cause refeeding syndrome, where sudden shifts in electrolytes and fluids can trigger heart failure, respiratory failure, or seizures.
Medical protocols typically involve starting with small amounts of easily digestible foods and gradually increasing quantity and complexity over several days or weeks, depending on the duration of the fast.

Anyone considering fasting for any reason should consult with healthcare professionals, as prolonged food deprivation can cause serious harm or death. If you or someone you know is experiencing health complications from fasting, seek immediate medical attention.
