The World Record Holder: Angus Barbieri's 382-Day Fast
In 1965, a 27-year-old Scottish man named Angus Barbieri, weighing a staggering 456 pounds (207 kg), checked into Maryfield Hospital in Dundee to address his severe obesity. What began as a short-term fast under medical supervision spiraled into a remarkable feat of endurance that would become the world record for no eating. With Barbieri insisting on continuing, and his body adapting surprisingly well, his doctors agreed to monitor him throughout an extended fast.
For 382 days, from June 14, 1965, to June 30, 1966, Barbieri consumed only zero-calorie fluids, including tea, coffee, sparkling water, and plain water. To ensure his survival and mitigate potential harm, he was also given vitamin supplements, yeast extract for essential nutrients, and electrolytes. He remained at home for most of the period, visiting the hospital regularly for outpatient checkups, including blood and urine tests. The medical community was astounded, with a 1973 study concluding that the prolonged fast had no ill-effects on his long-term health.
The Physiology of Prolonged Fasting
When deprived of food for an extended period, the human body enters a state of starvation and makes several profound metabolic shifts to preserve vital functions.
Phases of the Fasting Body
- Phase 1: Initial Glycogen Depletion (0–24 hours): The body first uses glucose from the last meal. Once that is gone, it draws on stored glycogen from the liver and muscles for energy.
- Phase 2: Transition to Ketosis (Day 2 onwards): After glycogen is depleted, the body shifts to ketosis. It begins breaking down stored fat reserves into free fatty acids and producing ketone bodies, which are used for energy, including by the brain. For Barbieri, his considerable body fat provided an extensive fuel source for this process.
- Phase 3: Protein and Muscle Breakdown: Once fat stores are significantly reduced, the body will begin to break down protein and muscle tissue for energy, a dangerous and potentially fatal stage. Barbieri's initial excess weight helped him delay this stage for an unprecedented amount of time.
Barbieri's medical team carefully monitored his electrolyte levels and provided supplements to prevent the severe imbalances that are common and dangerous during starvation. They also gradually reintroduced food at the end of the fast to avoid refeeding syndrome, a fatal condition that can occur when nutrients are reintroduced too quickly after a prolonged period of starvation.
Medical Risks and the Modern View on Fasting Records
While Angus Barbieri's story is a testament to human endurance, it is crucial to understand that his case was extreme and performed under close medical supervision. Attempting such a fast is incredibly dangerous and can lead to severe health complications, including heart attack, organ failure, and death.
Due to these risks, Guinness World Records no longer recognizes or encourages records related to fasting. This policy is in place to prevent individuals from attempting dangerous feats that could cause serious harm or death. The dangers of unsupervised, prolonged fasting are well-documented and include:
- Severe electrolyte imbalances (e.g., hypokalemia)
- Increased risk of heart arrhythmias
- Fatigue, dizziness, and cognitive impairment
- Refeeding syndrome, a potentially fatal complication upon reintroducing food
Comparison of Notable Fasting Cases
| Case | Record Duration | What Was Consumed | Supervision | Outcome |
|---|---|---|---|---|
| Angus Barbieri | 382 days without solid food | Water, tea, coffee, supplements | Yes (Medical Supervision) | Successful weight loss, maintained for years |
| David Blaine | 44 days without food | Water only | Yes (Medical Team) | Lost 25% of body weight, experienced severe health effects |
| Irom Sharmila | 16 years (intermittent) | Force-fed through nasal tube | Yes (Judicial Custody) | Protest against political act, suffered severe health consequences |
| Unsupervised Fasting | Varies (often weeks) | Water only or none | No | Highly dangerous, potential for severe injury or death |
The Aftermath: Life After the Record
Following his record-breaking fast, Barbieri enjoyed his first meal, a boiled egg and a slice of bread and butter, stating, "I have forgotten what food tasted like". He successfully maintained his new weight for years, showing that under the right conditions, a prolonged therapeutic fast could be effective. However, as time went on, he reportedly regained some of the weight. Barbieri passed away in 1990 after a short illness, having lived a fulfilling life.
His story remains a fascinating and cautionary tale, highlighting not only the amazing resilience of the human body but also the necessity of medical supervision for any extreme health regimen. Modern prolonged fasts, such as the 72-hour fast, are undertaken with strict protocols and under the guidance of professionals to minimize risks.

Conclusion
The world record for no eating solid food is an incredible 382 days, set by Angus Barbieri in the mid-1960s under meticulous medical care. This astonishing feat demonstrated the human body's capacity to subsist on stored fat for a very long period, provided the individual begins with a significant amount of excess body weight and receives essential vitamin and electrolyte supplements. However, modern medical consensus and bodies like Guinness World Records discourage and do not endorse such attempts due to the extreme and potentially fatal health risks involved. Barbieri’s story serves as a historical anomaly and a stark reminder that extreme dietary practices should never be undertaken without strict, professional medical supervision.
