When activist Sonam Wangchuk reported losing 8.2 kilograms during his hunger strike at a climate justice protest, it brought attention to a question many Indians wonder about: what exactly happens to the human body when someone stops eating for an extended period?
Hunger strikes have a long history in India, from Mahatma Gandhi's fasts to modern-day activists using the same method to draw attention to causes. While the political impact can be significant, the health consequences are severe and potentially life-threatening.
The First 24-48 Hours Without Food
When you stop eating, your body doesn't immediately panic. For the first day or two, your body uses glucose stored in the liver and muscles as glycogen. This is why people often feel relatively normal during short fasts. However, these glycogen stores are limited and typically last only 24-48 hours.
During this initial period, you may experience:
- Hunger pangs and irritability
- Difficulty concentrating
- Headaches
- Mild weakness
- Mood swings
Days 3-7: The Body Shifts Gears
After glycogen stores deplete, the body enters a state called ketosis. It begins breaking down fat stores for energy, producing ketone bodies that the brain can use as fuel. This is when weight loss accelerates dramatically—much of the initial weight loss is water weight as glycogen stores (which hold water) are depleted.
The weight loss reported by activists like Wangchuk—8.2 kg over several days—reflects this rapid depletion. A significant portion consists of water weight, glycogen, and some muscle tissue, not just fat.
Beyond One Week: Serious Health Risks
As a hunger strike continues beyond a week, the consequences become increasingly dangerous:
- Muscle wasting begins as the body breaks down protein for energy
- The immune system weakens, making infections more likely
- Blood pressure drops, causing dizziness and fainting
- Heart rate becomes irregular
- Electrolyte imbalances occur, potentially causing seizures
- Kidney function may deteriorate
- Mental confusion and cognitive impairment increase
The Role of Water and Vitamins
Many hunger strikers, including Wangchuk, continue drinking water. This is crucial for survival—humans can live weeks without food but only days without water. Some activists also take vitamins or salt, which can extend survival time and reduce some immediate dangers, though the body still deteriorates without caloric intake.
Long-term Consequences
Even after ending a hunger strike, the body faces challenges. Refeeding syndrome is a potentially fatal condition that can occur when nutrition is reintroduced too quickly. The sudden shift in metabolism can cause:
- Severe electrolyte imbalances
- Heart failure
- Respiratory failure
- Neurological complications
Medical supervision during the refeeding process is essential for anyone who has fasted for more than a few days.
Individual Variations Matter
How long someone can survive without food varies based on several factors:
- Starting body weight and fat stores
- Overall health condition
- Age and metabolism
- Environmental conditions
- Stress levels
- Whether water and supplements are consumed
Generally, a healthy adult might survive 30-70 days without food (with water), but severe health consequences begin much earlier.
The Psychological Dimension
Beyond physical effects, prolonged fasting affects mental state. Many hunger strikers report:
- Heightened emotional sensitivity
- Difficulty making decisions
- Visual and auditory disturbances
- Depression or euphoria
- Spiritual or transcendent experiences
These psychological changes result from the brain's altered fuel source and the stress hormones released during starvation.
Medical Monitoring Is Critical
Anyone undertaking an extended fast for any reason should have medical supervision. Regular monitoring of vital signs, electrolytes, heart function, and kidney function can help prevent permanent damage or death. Emergency medical intervention may become necessary if organ function deteriorates significantly.
The case of activists like Sonam Wangchuk demonstrates both the powerful symbolic nature of hunger strikes and the very real physical sacrifice involved. While the method draws attention to important causes, it comes at a steep cost to the individual's health, with effects that may persist long after the strike ends.

Anyone considering fasting for any duration should consult with qualified healthcare professionals. Prolonged fasting can be extremely dangerous and potentially fatal without proper medical supervision.
