What Kind of Results Can I Expect from Body Sculpting Treatments?

I am considering a body sculpting package at a local medspa. The package includes Mesotherapy, Pressotherapy, Electro-Stimulation Therapy, Vacuum Therapy, Lymphatic Drainage Therapy, and hot and cold body wraps. The cost is relatively expensive, and before I spend the money, I wanted to see if the procedures really work. I heard you can lose up to 20 inches or more and may help you lose some weight. Do you know what kind of results I can expect?
