Fat burning exercises and foods? How to lose 5-7lbs of body fat in 4 weeks?

I am auditioning for a professional cheer leading team and need to lose these final pounds of fat. I am 5’4″,128 pounds. Most of the girls are different heights but have very low body fat. You can see my abs some but I heard if you lower your body fat you can see them even more. What are some ways to trim down to a sexy physique in less than a month?
