A women's target weight chart gives a range of healthy weights for women of different heights and builds. Rush University Medical Center and Nutrition and Fitness Pro offer free target weight charts.
Since each person's body contains different amounts of bone, muscle and fat, a healthy weight may be calculated using the body mass index, or BMI. This tool estimates the amount of fat in a person's body. Those with a BMI of 24.9 or higher may be considered overweight, and those with a BMI of 40 or higher are considered morbidly obese.
Maintaining a healthy weight reduces a person's risk of developing coronary heart disease, high blood pressure, stroke, Type 2 diabetes, sleep apnea, osteoarthritis and colon, breast, endometrial and gallbladder cancers.
