Hi, I am no expert, but have been doing WW off and on for long enough to have come up with some strategies that work for me.
1. I always have the following on hand: egg beaters, medium salsa, no sugar added bread & butter pickles, 98% fat free flour tortillas, light english muffins, healthy choice low fat hot dogs, baby carrots, etc.
2. I also love having cooked broccoli in my fridge most of the time to add some no-point bulk to my meals
3. Fat free jello pudding cups are only 2 points and they are delicious
4. sugar free jello is another standard in the fridge for hungry moments
5. When I am cooking, I try to have a sliced cucumber or a can of cut green beans or the like at hand, as something to pick at, at a time when I am hungry but don't want to waste points
6. diet coke chicken and cauliflower "poppers" are good foods to cook in bulk and have in the fridge (I try to cook a lot on Sundays and put enough in the fridge for packed lunches and for quick dinners)
7. light string cheese is a quick, satisfying, protein fix.
WW is awesome because of its flexibility. Find foods you love and build your plan around them. We were in WDW last week, and I actually lost weight doing WW that week.
Good luck!
