I'm semi new here.

Been logging my stuff for a couple of weeks now. I have done the 17 day diet and I am staying on cycle 3 because i still have more weight to lose. However I am not meeting my calorie goal most every day. I am usually around 900-1100 calories at the days end, but I am always over on protein. I am very active and swim and bike and walk/jog or do a dyd of some type 6 days a week. How in the world can I make up 500 or 600 calories I burn off? If I don't work out at all I can get 1300 calories down, but I hate sitting around not doing anything. Please help! I have continued to lose at a slow pace. Am I going to stall or am I doing ok? I am afraid to eat to much and add calories but it f I need to what is the best way to up my calorie intake? Carbs? So do I wait until I stall or do I add calories now? I am so confused!
