Please help!

Dominique is a 17-year-old girl who is 20 lbs overweight. She is really shy and a little embarrassed by the fact that she has put on 30 lbs in less than a year. Dominique is an introvert who struggles with motivation to get fit. She also is saving up to buy a car and can not afford a gym membership at this time. She really wants to get in shape but does not know where to start.

What is some advice you would give Dominique to help her get on track with her goal of losing 10 lbs in two months?
