Battle with anorexia
Gold said around the age of seven, she thought about dieting, having learned the word and the concept on the many television production sets she worked on as a child actress. She became preoccupied with the television movie The Best Little Girl in the World, starring actress Jennifer Jason Leigh, about an anorexic teenager. In her autobiography, Gold says that in an attempt to control her development into a woman, she began restricting what she ate. When she was 11, she was diagnosed with the early stages of anorexia nervosa by her family pediatrician after a weight loss that accompanied a growth spurt. After some counseling, she eventually returned to a more normal weight for most of her teenage years. In 1988 at age 19, Gold gained some weight over the Growing Pains series hiatus. That season, the sitcom's scripts called for her to be the brunt of jokes about her being overweight from her television brothers for many episodes in a row.
Beginning in October 1988, Gold dieted from 133 pounds to about 110 pounds on a medically supervised 500-calorie-a-day (2,100 kJ) diet, but still occasionally the scripts continued to include weight-based jokes at her expense. In her autobiography, she says that between 1989 and 1991, she became increasingly obsessed with food and her weight and continued to slowly and steadily lose weight.
In 1990, Gold began group therapy in an eating disorder program, but only learned more ways to lose weight. That season, her problem with weight loss was touched upon slightly on her television series, when Gold is seen looking at her body in a carnival mirror, and describes to another character the distorted image in her head.
In 1991, she started starving herself more than ever and vomiting, and lost a great amount of weight, to the point that she was admitted to a hospital in early 1992. Her lowest weight is estimated to have been near 80 pounds. She was suspended from the show for her skeletal appearance. Photos of Gold's emaciated body were plastered all over tabloid magazines, and she was one of the first celebrities ever to be formally outed for anorexia. She last appeared in the 1991 episode "Menage a Luke" after missing the two prior episodes where her problem is very obvious in some scenes, and did not return until the last two episodes of the series in the late spring of 1992, although she was not nearly recovered at this point.
After several years' struggle, Gold eventually recovered, and starred in the television movie For the Love of Nancy (1994) with Jill Clayburgh. The film explored a young woman's battle with anorexia and its effects on her family. Although she was warned of the possibility that she had done damage to her reproductive organs by the years of anorexia, Gold was able to give birth to four children.
As she entered her thirties, Gold maintained a normal weight for her body structure, and often holds speaking engagements warning young women about the dangers of eating disorders, while continuing work as an actress.
