Here are 2 examples:
In 1965, 27-year-old Angus actually fasted for a year and 17 days. He did not eat anything and lost 125 kilograms.
Angus was reportedly fed up with being obese and checked into the Department of Medicine at Dundee Royal Infirmary weighing 207kg. He told the hospital staff that he was ready to give up food altogether, so the doctors agreed to monitor his progress.
Angus’s doctors did not expect the fast to last long. But they thought a short fast would help him lose some weight. To make up for his lack of nutrients, he was prescribed multivitamins to take regularly, including potassium and sodium, as well as yeast.
As the days turned into weeks, Angus’s persistence increased. He wanted to reach his “ideal weight” of 81 kg, so he went ahead, surprising his doctors.
Angus attended the hospital visits frequently and sometimes stayed the night. He received regular blood tests, which always revealed that his body was working remarkably well.
As the weeks turned into months, he made up for his lack of food by drinking more black tea, black coffee, and sparkling water, all of which are calorie-free.
His body began to adapt to the lack of food by burning its own fat stores for energy.
For the past eight months, Angus’ blood glucose levels were consistently very low, around 2 mmol/l, but he suffered no ill effects.
In the last few months, he started adding a pinch of sugar or milk to his tea and coffee.
For those wondering, he “goes to the bathroom” every 40-50 days.
Angus finally stopped after 382 days, having reached his ideal weight of 81 kg.
According to a report in the Chicago Tribune, he had forgotten the taste of food before his first post-fast meal. She ate a boiled egg with a slice of bread and butter for her first breakfast, telling reporters, “I really enjoyed my egg and I feel very full.”
Five years later, Angus stayed at a comfortable weight, weighing in at 185 pounds.
