Welcome to the board!
I don't know about the LA Weight Loss plan, but I know there's a bunch of supportive people around this board, and that establishing your support system is your first important step, so good job!
I don't think I'm an expert by any means, but I know something that has helped me is to stay positive and remember that it's a process of becoming healthy in our choices and actions so setbacks will happen, but you have to keep moving forward.
Keep positive, and see what happens! I look forward to hearing about your journey!
