A British man renowned for undertaking the longest recorded fast has shared insights into his dramatic weight loss journey.

Angus Barbieri, hailing from Scotland, became a global sensation over sixty years ago when he committed to a 382-day fast to shed excess weight.

In June 1965, faced with morbid obesity, Barbieri resolved to confront his eating habits and transform his health, according to History Defined.

Throughout his fasting period, Barbieri reportedly lost an impressive 1.5 stone each month, establishing an unprecedented record.

His feat astounded both scientists and the general public, as he surpassed all previous records and challenged existing beliefs about human endurance.

The question remains: How did Angus navigate this extraordinary path, and what were the impacts on his physical and mental well-being by the journey’s conclusion?

Life before losing weight 

Very little information exists about Barbieri’s days before his weight loss. He was born in Tayport, Scotland, in 1939 and appeared to have lived a fairly normal life.

As a young adult, before he began fasting, Barbieri was working at his father’s fish-and-chips shop.  

But by 27 years old, Barbieri’s problems with weight became apparent, as he weighed 456 pounds.

In June 1965, he voluntarily admitted himself to the Royal Infirmary of Dundee in Scotland to under go a short fast in a bid to lose weight. 

It was during that time that Barbieri would then continue to fast his way to health for an extraordinary 382 days. 

Barbieri’s fast 

The consumption of solid food was not permitted during Barbieri’s specific fasting plan. 

He was only allowed to ingest electrolytes, vitamins, some yeast for important amino acids, and finally, particular liquids such as black coffee, tea, and sparkling water.

Barbieri’s calorie intake remained close to zero for the entire duration of the prolonged fast – essentially a ‘starvation diet’ intertwined with intermittent fasting. 

During his fast, Barbieri was losing weight rapidly – shedding almost a pound a day on average. Every month, he was losing around 22 pounds.

Months on, Barbieri remained committed to the fast and the digits on the scale continued to decrease.

He was surprisingly permitted to come and go as he pleased from the Maryfield Hospital he was receiving treatment at, but Barbieri’s doctors had to accompany him to monitor his diet. 

But the success of his fast wasn’t without its downfalls. Barbieri had to quit his job at his father’s fish and chip shop on Nelson Street to avoid breaking his strict diet.

Breaking the fast 

Barbieri’s ultimate goal was to reach 180 pounds at which point he would plan to end his weight loss journey.

And, after a painstakingly extraordinary 382 days, on July 11 in 1966, he finally reached his target after losing a whopping 276 pounds. 

Barbieri ended his fast that July morning with some bread and butter and a plain boiled egg.

He told the crowd of press in the room: ‘It went down okay. I feel a bit full, but I thoroughly enjoyed it.’

Barbieri’s transformation made it difficult to recognise who he was from looking at his earlier pictures. Remarkably, he was reportedly able to fit two people alongside him in his old pair of trousers. 

His story quickly became a global conversation, with newspapers as far away as the United States reporting on his incredible journey.

The University of Dundee was so intrigued by Barbieri’s weight loss that they conducted a study on him to examine the effects of long-term fasting on the body.

His doctors documented the entirety of his treatment in a case report describing the experience that was published in the Postgraduate Medical Journal in 1973.

Science and skepticism

Angus Barbieri’s weight loss journey was met with much skepticism and controversy, as his fast went far beyond what almost anyone thought possible.

Many people asked the same one question: how could anyone go that long without any food?

Many believed that going beyond an entire year without food could not result in a totally healthy body, regardless of the benefits from losing so much excess weight. 

At that time, records showed there were five deaths due to people attempting similar long fasts under hospital supervisions. 

Despite all manner of doubts and suspicion from family, the press, and even some of his own doctors, Barbieri insisted that his methods were both strict and honest. 

Barbieri’s legacy

To this day, Angus Barbieri’s record fast of 382 days without food remains unbeaten – it may even never be attempted again. 

Barbieri’s fast was recorded in the 1971 Guinness Book of Records – the longest ever recognised. 

The only ever closest ‘competitor’ was Dennis Galer Goodwin, who under went a 385-day hunger strike in 1973. He was, however, force-fed during the period, and so Barbieri’s record still stands. 

After recovering from his incredible fast, Angus continued to live a fulfilling life, raising two sons, later moving away to Warwick. He died in September 1990. 

Barbieri still holds the world record for the longest fast without solid food. However, Guinness World Records no longer endorse or support any records related to fasting or dieting – including Barbieri’s – due to concerns about dangerous health effects.
