Calories

I'm not sure why you think you should be eating less when you've specifically been given a target. Eat more, even if it's peanut butter with a spoon, some string cheese/yogurt, nuts and seeds (separate or with food).

A GOAL is something you should try and reach. That's why it is called a goal. You don't want to be extremely under your goal and working out on top of it. You might want to read some of the stickies at the top of the page so you better understand how MFP is designed to work. Good luck!
