You should get your cat one of those whips with a feather at the end of it that will force her to jump to catch it. That way you can play with her without risking your hands and feet. Also, you should get her something to climb on and a scratching post to stretch her muscles. If she doesn't drop some weight after a couple months, you might to send her to a veterinarian. Sometimes, cats can have thyroid or health problems that make it hard to lose weight. You might also need to change the food, if it has a lot of fillers. My cat lost his love handles when I switched from hard food to soft food because there was more meat in it. Sometimes cats can't handle the carbs in cat food because they are carnivores.
