Richard Carpenter recalls that Karen was "a chubby teenager". Genetically, she wasn't meant to be super thin. Unfortunately for this singer, the only body that she would stand to have was a thin one. The dieting began in 1967 when Karen's doctor put her on a water diet, bringing her weight down from 140 lbs to 120. When she had made it down to 115 lbs, people told her she looked good, but she could only reply that this was just the beginning of the weight loss, and that she wanted to lose still more. By the fall of 1975, Karen was down to 80 lbs. She was taking dozens of thyroid pills a day, and throwing up the little food that she ate. Karen's body was so weak that she was forced to lay down between shows, and the audience was gasping at her body as she walked on stage. It was this year in Las Vegas that Karen collapsed on stage while singing "Top of the World". It was a big scare to the audience and her family. After being rushed to the hospital, it was reported that Karen was 35 lbs underweight. It was this final collapse that made Karen Carpenter realize that she had a serious problem. She went to doctors and therapists, and eventually began to believe that she was well. However, in reality, her body was still suffering from the lack of food, the over dosages of laxatives, the lack of sleep, and the anxiety of being on the road. When she died in 1983, it was a shock to many people who believed that she had been cured.
The emergency call came at 8:51 am on February 4, 1983. Karen Carpenter's mother found her naked and unconscious on the floor of a walk-in wardrobe closet in their home in Downey, California. At the age of 32, she was 5'4", but weighed only 108 lbs".
