Weight Watchers to kill my plateau?

First think I'd say is that you aren't eating enough. Way too many 900 calorie days in your diary, and that's not enough food, and eating too low isn't giving your body any reason to want to burn fat.

If I were you - first thing I'd do is go read this topic: http://www.myfitnesspal.com/topics/show/974888-in-place-of-a-road-map-2k13 Read it twice, or ten times if you need to, but read it and understand the info there. Then grab a measuring tape, and using the tools and step by step instructions in the thread, run your numbers and find your BMR and TDEE. Make sure you follow the steps in the thread, which are slightly different than the instructions on the calculator.

Once you're armed with these numbers you have your boundaries - you want to eat in between BMR and TDEE, probably about a 20% cut from TDEE to get your daily goal.

You mentioned strength training - if you have access to heavy weights, like barbells and all the big stuff, start a lifting program like Stronglifts 5x5 or New Rules Of Lifting for Women. If you enjoy running, keep at it, but don't go crazy with it - three days of lifting, three days of running (or walking, or kickboxing, or whatever cardio you want to throw in there). Take rest days.

Absolute best results I've had with losing the fat has been since setting my goals according to that thread. And I don't even lift heavy - no gym, and no space at home for the big weights, but I do the best I can with dumbbells at home, and running - my workouts are rarely over an hour per day, and if they are it's usually because of a 20 minute dog walk.

Eat well - food is fuel! Eat your calories, drink water, exercise, get good sleep, take rest days, repeat.

I am seriously excited to try this out! Can you add me and help me out? It's so frustrating to me that I can have fast food for my meals for 3 weeks, be 176 and then run 5k 3x a week for months and be 6lbs less!!!!!!!!!!!!!!! FML!
