Lost 40 lbs but have plateaued, opinions please

[BuckeyeROC]

Hey guys. I've been on a 2600 cal a day diet since Feb. and log absolutely everything I put in my body with fatsecret.com's phone app and use a food scale to measure out when needed. I lost most the weight at a fairly steady ~2 lbs a week. The last few months though, I've absolutely plateaued.

For exercise, some days my job involves all day at a desk, other days I am walking and up and down stairs for 6-8 hours a day. I also do a weightlifting program similar to HCT-12 3 days a week and usually run sprints or do the elliptical 2 days a week if I have too many days at the desk.

I'm a 35 year old male, 6'3" barefoot, started at 303 lbs. My weight now varies between 261-265 the past few of months and will NOT get lower. I've tried some cheat days here and there and have even taken a couple entire weekends to cheat. Trying to raise my metabolism. I'm a life long drug free guy, no prohormones, steroids or anything else like that, ever. Supplements include a multi, fish oil, Nitrean+, and Results.

I was thinking of going to a 2900-3000 cal a day diet for a month to see if that helps any, then maybe drop it back down to 2600 cals to try to lose more weight? Just want your thoughts on how to lose the last 10-15 lbs and reach the 250-255 range. Any suggestions would be great. Thanks.

If you are able to see these pages, here are my weight loss chart and food diary. Days with unlisted cals were cheat days and days with very low cals, I had a cheat meal for dinner. I never drink ANY calories:
