Diet Meal Delivery - Nutrisystem, Medifast, Jenny Craig, Etc - What Has Worked for you? help :)

Hi! I am new here but, I was wondering what meal delivery plans people have used that really worked for them. I am thinking about the Leviv one that is on the home page for this site. I am in college and live in the dorms so it would only be practical for me to do this over the summer. I am a not a picky eater but I do enjoy higher quality foods if that helps. Any input would be greatly appreciated.
Thanks!! :)
