Claire Simmons, 33, reportedly has selective eating disorder - likely to have developed from an unwillingness to try new foods - and as a result hasn't consumed anything else other than cheese and tomato pizza since the age of 2.
She told The Sun that she gags if any other food is in her mouth.
Simmons stated: "I keep myself healthy with exercise and drink a lot of water.
"But my GP says I'm storing up many problems for the future due to a lack of vitamins and minerals."
Simmons, who shared her story with the tabloid newspaper after reading about the teenager who lives on a diet of chicken nuggets, adds that she too has been warned about the risks of continuing with her diet.
She also defended herself despite not eating any fruit or vegetables, saying that she's "scared" of them.
"I get so angry when people think I'm being faddy," she commented. "This is a real medical condition."
