Starting all over again

I did my fitness pal a few years ago and was pretty successful. since then I put on a fair amount of the weight I lost so I decided to do it all again I'm encountering problems though. Originally I set my goal to a 1.5 pound a week weight loss which was what I was doing before. I started tracking a week ago and I can't seem to eat enough calories in a day. I work in a kitchen I'm on my feet most of the day it's fast paced and I walk on average 2.5-3 miles a day jut at work. I am not a breakfast eater and pretty much drink my morning calories in my coffee every morning at around noon I will have a yogurt then I will make a salad with some tuna or lean chicken I don't usually do dressings on my salads because of the sodium content in the packaged stuff I have a work. I purposely leave around 300 calories uneaten a day because I do taste things throughout the day or if I do get hungry will munch on some carrots or fruit and I don't always remember to log it. 3x's a day I walk an additional 2-3 miles for excersize purposes Problem is I'm coming way under my goal the MFP designated for me. I adjusted my weight loss to 2 pound per week and still can't seem to make my 1500 calorie goal. Thing is Im not hungry and I can't bring myself to eat when I'm not hungry eating when not hungry is what put this 70 pounds I'm trying to lose on. I completly understand that I need to eat I'm eating lots of fiber and protein and I've been snacking on almonds and other healthy fats. I'm afraid I won't be successful because I'm not taking in enough calories. I've never encountered this problem before usually I'm starving if I suddenly decide to diet. I''m. Eating on average 1250 calories a day but am burning twice that based on my fit bit info. I can't eat back my excersize calories I'm just not hungry,

Has anyone else encountered this problem, and if so how did you overcome it.
