<human>: So, I have been running A LOT lately and have had no issue staying within my calorie goal and having a deficit.  Well, today I am resting because I started reading up and I really shouldn't run every day.  With that, I won't have a chance to work out today because we are going out straight after work to a function.  

According to MFP, I only have like 300 calories left for the day.  I find it very difficult to have a deficit at the end of the day on days that I don't work out.  How do I stay within my 1200 calorie range and not be hungry?  I've eaten right today - skipped the cupcake for my coworker's birthday, walked by the delicious cookies sitting in another department - but still manage to eat my way through 900 calories with dinner still left.  

Does anyone have any suggestions on low calorie, FILLING and easy to prepare foods?  I am trying to eat more at home to save money and to eat better and I like things that are quick.  Also, I tend to not get up with enough time to make anything in the morning so like today, I walked out with a piece of wheat toast with low-fat peanut butter and a banana.

Also, if I work out, is it ok if I eat 1500 calories?  I assume I'm in the clear as long as have at least a 500 calorie deficit - right?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I'm having a hard time staying full and staying within my calorie goal of 1200 on days that I don't work out.  Need suggestions on FILLING, low calorie foods.
