During Her Freshman Year of College, Rhonda Experienced Many Environmental

During her freshman year of college, Rhonda experienced many environmental changes that influenced her diet and lifestyle. She was fearful of gaining "the freshman fifteen" and also had a limited food budget. To save money and avoid gaining unwanted weight, she decided that she would only eat fruits for breakfast and salads for lunch and skip dinner. Soon she found herself getting very hungry in the evenings, and she would then overeat food from the vending machines and cheap fast food. She often snacked on cookies, fried foods, pasta, ice cream, and diet soda. As the school year progressed, Rhonda had recurrent bouts of respiratory illness and felt chronically fatigued. Upon visiting the college health service, the doctor diagnosed her with iron-deficiency anemia and speculated that in addition to not getting enough iron she was probably not getting enough protein or B vitamins. It is now the end of the school year, and Rhonda's overall health is poor. She has also gained a significant amount of weight despite not eating dinner and inadequately consuming nutrients overall. Rhonda decides to register for a nutrition class over the summer and learn how to better manage her diet and weight during her sophomore year.
