Hi 2much -
LA Weight Loss (LAWL) is basically a low-carb, high-protein diet with a strong emphasis on portion control. When you join your current weight and WL goals are evaluated and you are assigned to a "plan" that allows certain foods (a fairly wide variety), of which you are to eat a certain number of portions each day.
Cooking is highly encouraged simply because then you control your portion sizes as well as all the ingredients, but it is possible to eat some fast food and frozen dinners, as well as ordinary dining out. If you have seen or heard the commercials that say you can "eat whatever you want," well, that's not entirely accurate. But the program will definitely teach you how to make the healthiest choices when faced with "everyday life."
There are quite a few threads on here from other potential and new LAWL members that may have answers if you have more questions, too.
Counting down to my pre-pg weight:
