Kat, I come from a rather large family (lol.. yeah just about -all- of my family is overweight or bordering obese) and my mother did weight watchers for a while, although not very successfully.
I dont take after my family at all lol, and keep an extremely tight diet and exercise every day, some tips I would give you include:
1. I know you dont like the cold, but running or jogging is one of the most surefire ways to lose weight and burn calories, not only does it do that, but believe it or not, it actually tones your stomach too, if you can, try running 4-5 times a week, start out slow, run about 1.5 miles at first, and build up half a mile each week, not only will this improve your metabolic rate, your energy level, your tone, and your weight loss, but it will balance your diet vs your exercise level to a huge degree.
2. It's really easy to eat sweets and the like, because yes! Sweets are good!
Try and give yourself a goal, whatever you see fit, perhaps cut down foods high in saturated fats and sugar, eat more green vegetables etc, I know you keep a balanced diet being on weight watchers, but eating foods with the right nutrients helps a lot!
3. Eliminate soda -completely- you will not believe just how much weight people retain simply by drinking those carbonated fluids, soda is a huge killer, and actually proves to dehydrate you more than help you, soda is really nothing but empty calories.
4. Fast Food is perhaps the biggest downfall of america, extremely high in grease, saturated and trans fat, and extremely lacking in nutritional value, yes that greesy burger is delicious, but you will feel it the after a while.
5. If you can, do a small workout every night before bed, even if it's something little like doing a certain amount of crunches each night, or pushups, or both. Staying active before a rest period will increase your metabolism, but avoid eating right before you sleep.
Other than that ^^ sounds like you have things under control, and like others have said before me, remember that muscle does way more than fat, and as you exercise and improve your fitness level, you will gain some muscle weight here and there, but lose body fat percentage. I know as a 6 foot 1 inch tall male, I exercise daily, running nearly 3-5 miles per day, I have not had fast food in over 13 months, and not had a single soda in over 15 months, i stay away from foods high in saturated fats, and eat three meals a day, which helps a lot, and I maintain a very healthy stature and build weighing in at 179 pounds. Hope this helps =) good luck!
My mom and sister are ~5'3". All her friends are shocked to meet me. I hear a lot of "He came out of you?!!!".
