The WW Boards are some of the nastiest people you'll ever deal with on many of them. The 200+ Board is ok and the Scale one is ok but no one is dishing out the real answers and being polite and friendly like 3 fat chicks.
The way to do something about this is to break bad habits. You live at home so you have to move. What you do is buy some cheap if you don't have ear phones and listen to music and walk in the neighborhood, the stores, the malls, wherever you can. Maybe a park in the evening but walk you must.
Food is going to be planned. Pick your fav Plan and get going on it. Cook it, freeze some, but you have to view those junk foods as frankenfoods from a lab. They are going to get you sick by packing on the pounds and adding lots of unwanted calories, sodium and fat. Making you not lose weight is not where it's at.
Fruit as a snack will allow you the sweets without the weight gain and veggies with a little low fat cheese wil also help you out. Don't overdo on carbs like crackers. They're a bad food because you'll eat more than you should. If you're famished, eat a bowl of cereal, fruit and skim milk. I did this and saved myself from failing.
I'm today starting day one of week two. I'm down 8 lbs. from eating properly.
