The adolescent years are important because they bridge the gap between childhood and maturity. Optimal health and nutrition may be attained during this time, which is considered the second window of opportunity following infancy. Adolescent females also reach around half their adult weight and height at this time, making it an important developmental window. Adolescent girls who are malnourished not only put their own health at risk, but also perpetuate the cycle of hunger that has plagued their families for generations. One hundred rural teenage females in the Kannauj area of Uttar Pradesh, ranging in age from 10 to 19 years old, participated in this cross-sectional research. The current research aims to quantify the rates of short height for age, low body weight, obesity, and health education. The research found that among rural teenage females, underweight is more of a health concern than fat. Twenty percent of the sample population is underweight, whereas just six percent are overweight. Poverty, illiteracy, unemployment, food insecurity, and other aspects of rural living have been hypothesised to contribute to the prevalence of thinness there.
