Good advice, but I wouldn't completely eliminate breakfast. She just doesn't have to overdue it. Eating oatmeal, fruit or something along these lines will definitely benefit her and also help with her digestion. People tend to forget that your body has been fasting for 8 hours (sleep) so to start the day out with nothing might help lose weight, but isn't healthy in the long run. A big glass of water first thing in the morning is also very beneficial in speeding up her metabolism and cleansing her system.
I also would also mention eating a big/medium-sized dinner 3 - 4 hours before bedtime.
Lastly, make sure you get a good night's rest every night. Helps your body to recover from the regular workouts.
