I'm going to guess you're more than 35% BF. That means your maintenance calories are probably lower than what you're using as a base. I'm also thinking you're very sedentary if you're reporting a 30 minute walk as exercise. 10 miles on a bike at 13.5 MPH is about 400 calories. Do that for 9 days and you'll lose one whole pound. Step up the exercise a bit, either in intensity or duration. Looking at your diet you should be losing about a pound a week, but at your weight your gut contents and water retention/loss spikes will make that difficult to measure. What are you drinking? Have you missed any calories? Are you exercising before you eat or after?
Also, start thinking about which changes you've made in your diet would be acceptable as _permanent_ changes. The small things really do add up over time, and making permanent changes _you_can_live_with_ is the road to weight maintenance after losing weight.
