Seem to be stuck...

The weight loss has slowed down a lot again.  Last week I was down only .8, week before only .2.  So far this week I've stayed exactly the same as my weigh-in.  I know I've been extra hungry this week due to my period!  But I'm also feeling like I need to switch things up again.  Louie and I are still going for walks 3 times a week at lunch, and I'm still doing the strength training 3 times a week, but I'm wondering if I need to do something different or something more.  I've been thinking about trying kickboxing or Zumba, and I was also thinking about picking up my walking DVD again.  Maybe I've lost enough weight now that I need to adjust my calories.  Maybe I need to eat more fruits and veggies.  Not sure what I need to do, but I'm stalling out.  I'm so close to 40 pounds lost, and I want to get there!
