Uh oh..I think that maybe I'm eating the wrong Ricotta Cheese. The one I bought is Ricotta Light and it's 5% MF. I've just noticed that I'm supposed to be using part skim, not the same right??

I think you're okay Jenn... go to the FAQ section of South Beach and review the Emergency Handbook for Phase 1... In general part skim and LF cheese is okay -- look for cheeses that are less than 6% fat ... (just check to see that when lighten stuff up it is not replaced with sugars) Here's an extract from the food list in that Emergency Handbook

American
Cheddar
Cottage cheese, 1-2% or fat-free
