I started with LA Weightloss 6 weeks ago, and I've lost 18.5 lbs.

They've given me a food plan to follow, that gives me a certain number of servings of fruits, veggies, protein, startch, etc per day. I keep a journal of everything I eat.
I weigh-in 3 times per week, and meet with a counselor each time. She goes over my journal, asks questions, and helps me make healthy decisions if I have a special event/party that I'm going to be attending.
I think I made the right choice with LA...with WW, I found myself cheating after weigh-in day, and trying to make up for it the rest of the week. With LA, I don't have the opportunity to cheat, because I have to be weighed every other day, and the personal counseling forces me to be more accoutable for my actions.
I paid $6/week for a 34 week program (for a 68lb weight loss goal) and a year of maintenance, up front. This doesn't include their supplements, or the protein bars and shakes that you're required to consume everyday.
I hope this helps a little. Let me know if you have any questions!
