Hi lisalisa,
Here are the points for what you have been eating (although I don't know your portion size or brands so this is approximate).
low fat yoghurt 1.5
portion strawberries 0.5
small bunch grapes 1
portion blueberries 1
2 rings pineapple in juice 0.5
tub low fat cottage cheese 2
1 teaspoon olive oil 1
1/2 avocado 3
banana 1.5
3 small plums 0.5
sweets 1 - 2 depending on how many you eat!
portion lentils 2.5
portion rice 4.5
tablespoon kidney beans 0.5
You are doing really well with the food you are eating. If you aren't losing weight then I would watch out for portion sizes, the olive oil and rice if I were you. Maybe switch to a low fat dressing instead. For the rice, WW say that a 60g portion of uncooked rice = 3 points. This should help you keep an eye on how much you are eating.
Keep drinking lots of water too and if you can do some exercise. 30 minutes of swimming = 4 bonus points, and 30 of gentle walking = 2. A jaffa cake is a point. Yum.
Good luck, I hope the weight starts to come off again soon. If you want some of the WW books/calculators have a look on Ebay, there are loads for sale and much cheaper than at the meetings.
