I have hit a plateau and NEED HELP!

Hello there fellow friends! I will try to sum up for you all shortly what has been going on the last 4 weeks. I have had pretty steady weight loss over the last 5 months. I hit my goal of 150 pounds after 28 pounds of weight loss the first week of October (2.4 pounds lost that week) Since then, I have had NO WEIGHT LOSS. I haven't gained, thank the Lord, but my loss had halted totally. Take a look at my food diaries..... I eat healthy grains, fruits and veggies almost everyday and I work out 5-6 times a week at an hour minimum. I am just wondering if I am eating too few calories and my body is holding onto weight or if I am not pushing hard enough? I am really confused. I just recently purchased Insanity and plan on starting that monday, but I am not totally sure what it is I should be doing as far as diet.... ANY IMPUT is appreciated and feel free to tell me like it is. Also what is everyone's thoughts on net calories vs. food calories. THANKS SO MUCH!
