Congratulations! I think you're doing all the right things, you wouldn't have lost 30 pounds if you weren't doing something right! It sounds like you just need to get more movement/activity in...how about getting a pedometer and tracking the # of steps you take a day? Here's what I did when I was losing weight: I snapped on the pedometer and tracked my "average # of steps" for the first 3 days. I didn't just track 1 day because some days, based on what you have going on, you just walk more or less than others you know? After that I took my average # of steps for the 3 days (approx. 4,100) and decided to increase it by a minimum of 100-150 steps per day until I had worked up to the suggested # of 10,000 steps/day for weight loss. Yes this was a slow way to do it, some people may have added 1,000 or more steps per day and that is OK too, but I was determined to make this a gradual "lifestyle shift" not just a spur of the moment thing to try and get to a certain # right away. It worked! As I started adding the 100 steps and my legs got stronger, it became easier to walk longer and there were some days I walked close to that 10,000 without even knowing it. Other days when I wasn't so active I made the conscious effort of not going to bed until I had walked my average at least so I would just march in place in front on the TV for 30 minutes. The weight started to fall off my lower body so much quicker.
Hope that helps! You're doing awesome and I think you already have the right mindset to continue losing weight. Good luck!!!
