Straight from the pages of a 1977 Vogue magazine, the diet promises women they will lose 2.5kg in three days by following their instructions.
The backwards diet plan tells readers to have a glass of wine three times a day, including with breakfast.
For breakfast, Vogue suggested a woman should consume a hard-boiled egg, washed down with a black coffee and a glass of white wine.
Lunch was two eggs, two glasses of white wine and another black coffee.
Amazingly, dinner included a 5 oz steak with the remainder of the bottle!
A picture of the diet plan was shared to Twitter, leaving many people shocked and amused.
‘A "crash diet" from Vogue in the 70s. I think I'd crash about 20 minutes after lunch,’ one Twitter user wrote.
How times have changed!
