Advice appreciated

I would appreciate some eating plan suggestions. I pretty much stalled out this week. I may be jumping the gun but staying in the same pound range for a week is too long for me considering that I feel like I have been more strict this week. It's making me antsy and my first thought is that I need to be more strict but not sure what I could do without going too crazy. I've only been tracking for the last 2 and a half weeks but lost about 17 or 18 lbs from March to May eating pretty much the same way, so I'm sure I was right in the calorie range I am now. MFP gives me 1200. I have been just to either side regularly. I didn't work on my weight from the last of May to mid July and picked up where I left off at 204. I say that to say I don't think the 5 lbs I lost since I started working on it again was water, so I don't know why the scale isn't moving?

I will open my diary and would appreciate some suggestions. I haven't been working out, though I did have one day last week where I never sat the whole day and was doing heavy cleaning/decluttering and that was about the last time I saw the scale move. I hope to become more active but didn't want to start off with anything too crazy because I don't want to start something I'm not going to keep up with. I hope to get a treadmill in the next week or so and do some modest walking. As far as food, I'm trying to stick to whole foods, good carbs., and lower cals. I'm not sure if I need to eat more or not. I lost 45 lbs six years ago eating just this way, however, I was exercising. Thanks for any tips.
