Having difficulty consuming a healthy diet

I just hope that my weight has come down today.  I wonder if that is the case despite my diet.  I consumed fried chicken breast fingers today.  They were the only things I ate for lunch.  I also had grapes and pudding for breakfast.  For a snack, I had a grilled cheese sandwich.  I do wonder now why my diet is so poor.  I have trouble with planning meals in advance and sticking to them.  That has been an issue that I have had for a long time now.
