This 130-pound woman wants to maintain her current weight but tone up and get in

This 130-pound woman wants to maintain her current weight but tone up and get in better shape. About how many calories should she be eating? Should she make any changes to her diet or activity levels? What do you suggest?
Hint: Start by using the simplified equation and an activity factor to calculate her total energy expenditure. This is her “energy out.” Then look at her daily energy intake below. This is her “energy in.” If they are not in balance, how can she modify either energy in or energy out to get back in a state of energy balance. There are lots of different correct answers here. I want to see what you can come up with.
Exercise Routine
• Unstructured: Most of her time is spend studying but she gets some activity walking around campus between classes and riding her bike around town.
• Structured: Usually 1-2 days a week. Mostly moderate cardio such as the elliptical. If she remembers she does some body weight activities at home.
