My plan for today (from the "what are you eating today?" topic):
B: 1/2 cup prepared fibre one pancake mix, sugar-free syrup, 5 slices veggie ham, 1 cup cantaloupe/blueberries (400)
S: (skipped, ate breakfast late, had a pot of oolong tea instead)
L: Salad, baked chicken breast, light baby bel cheese, vinaigrette (300)
S: Strawberry yogurt cup (100)
D: Chicken noodle soup w/ spinach (300)
S: 100 calorie cup of ice cream
=1200
I like "what are you eating today?", it's good for ideas.

My plan works for me because I like to eat my "biggest" (400 cal) meal before I leave for work (6 am), and eat relatively lightly for the rest of the day. I don't do elaborate productions for dinner because I work ten hour shifts and cooking is just not a big priority for me when I get home.
If you're planning to stick with a 1200-1400 calorie plan consistently you'll want to make sure that it works with your schedule, that you like the food you're eating, and that it's nutritionally balanced - there's not a lot of room for error if you're really restricting your calories.
Good luck!
