6. Michele Koebke
Michele Koebke is a German woman known for extreme waist training using corsets. She has worn corsets for three years to reduce her waist from 25 inches (64 cm) to 21 inches (54 cm).
In an interview with The Huffington Post, she stated that she wears her corset even while sleeping and removes it only to shower. Since 2008, her waist size has decreased by 9 inches.
Her transformation is a form of extreme body modification, often compared to tattooing and piercing in its dedication to altering one’s physique.

Doctors have warned that further waist reduction could lead to serious health risks, including paralysis.
5. Lizzie Velasquez
Lizzie weighs only four stones and has nearly no body fat, yet she cannot gain weight due to a hereditary problem, which accounts for her look.
Lizzie’s parents were warned she might not live when she was born, but today, the motivational speaker has graduated from college with a degree in communications.
Neonatal Progeroid Syndrome, which the 33-year-old has, causes early aging, wrinkles, and fat loss beneath the skin.
She is one of the three individuals worldwide who have been diagnosed with the illness.
Since Lizzie has a condition that prevents her from gaining weight, even if she consumes thousands of calories daily and eats almost every 20 minutes, her weight never rises above 27 kgs.
4. Ioana Spangenberg
Iona Sapangenberg swiftly earned the moniker “Human Hourglass” for her Barbie-like 32-20-32 physique when her pictures and videos went viral this week.
The 30-year-old model of Romanian ancestry who now calls Germany home maintains that her 20-inch waist results from nature and not a lack of hunger.
She claims that as a child, she had a normal weight and that the transformation started when she was a teenager.
When she was 13 years old, her waist was just 15 inches broad, and her friends could fully wrap their hands around it. She would eat Mars bars and other sweets to put on weight, but nothing worked. She is only 38 kgs.
3. Cathie Jung
Cathie Jung, born in 1937, is known for her dedication to corsets and Victorian-style clothing. She lives in Manteo, North Carolina.
Cathie would be the ideal illustration of the thinnest lady in the world who made herself that way. She is called the “corset queen” because she used corsets to give herself the ideal body.
Cathie Jung consistently wore a corset for more than 12 years to acquire a small waist. She currently holds the Guinness World Record for having the lowest waist of any living human, a weird world record certainly.
Her waist was 15 inches. She stands 1.72 metres (5.6 feet) tall. She is currently 70 years old and has 43 kgs.

He is 1.91 metres tall and weighs 65 kg, which is considered very low for his height. Medical evaluation revealed that he has MDP syndrome, an extremely rare condition with only a few known cases worldwide.
This condition causes a near absence of subcutaneous fat, especially in the face and limbs, giving him an unusually thin appearance.
1. Valeria Levitin
Valeria Levitin, an extreme anorexic who weighs only four stones, around 27 kgs, is the world’s thinnest woman.
She should have been given a stark warning about the consequences of eating disorders, given her emaciated appearance and matchstick-thin thighs. In an interview with the Sun, Valeria Levitin reportedly disclosed the rationale behind the diet plan.
She acknowledged that she desired a trim physique. Russian Valeria Levitin, who experienced an eating issue early on, blamed her mother for the situation.
Valeria’s mother put her on a diet when she was 11 years old out of concern that she would become an obese adult.
The world’s thinnest woman, Valeria Levitin, revealed this depressing tale. Valeria Levitin, 35, went on a diet for several years, which led to anorexia and transformed her body shape from that of a lovely, healthy woman into something else.
