DescriptionSara is a 45 year old full-time customer service representative.  She is the mother of two young children and to help in saving money for their college, she works an additional part-time job at the local library one to two evenings per week and every other Saturday.  Sara has a hectic schedule between her two jobs and her children’s activities.  Sara’s typical day includes getting her children ready for school, which means she often leaves the house without breakfast or stops by the local donut shop on the way to work to pick up a pasty and coffee.  She usually visits the local drive thru for lunch, and relies on quick and easy frozen dinners for many of the family’s evening meal.  Sara has little time to plan the family’s dinner meals and her husband Sam works long hours.  She finds dinners are focused on what is convenient.  Sara has little time for physical activity.  Unfortunately, Sara’s weight has increased over the past few years.  She is 5 feet, 2 inches tall and weighs 165 pounds.  Recently, Sara’s employer had a health and wellness fair where Sara found out her blood pressure was elevated and her total blood cholesterol is above the optimal level.  Sara feels that her weight is starting to impact her health and would like to make some positive health changes.  She has even thought about investigating popular weight loss diets that her co-workers have talked about.

4)      Calculate Sara’s Estimated Energy Requirement (EER) and Body Mass Index (BMI).  What category does the BMI result indicate?
