KAIT ~ well, I do portions with a daily calorie cap; but I eat more balanced to keep my blood sugar levels balanced too. I usually have 3 meals with 1-2 snacks each day. I like chicken a lot, having it at least 2-3 times a week; lean beef or pork once a week; pasta 1-2 times a week & one meatless, if I can swing it. I try to eat one salad a day and at least 2 veggies; plus 1-2 fruit a day, sometimes cutting an apple or banana in half and having later on in the day.
I like to snack on fruit, yogurt, cheeses, NSA jello pudding, 4 x ww soda crackers, homemade lowcal fiber muffin, or a toast & PB if I'm low on my cals. I love veggie Pita Pizzas and have them about 2-3 times a week for lunch. I like to have a .5 eggwich sandwich w/chz for breakfast 3 x a week, and alternate with cereal 2 times. I like to have a 200 cal bagel & pb on the weekend; and maybe an egg or omelette & 2 slices bacon + 1 slice tst on Sunday.
We have soup often here; either I make it, or I have a cupasoup with a sandwich on my other lunch days. We do have a Friday Fun meal on Friday nights but it must fit into my plan. We eat whole grain most everything. That is my plan in a nutshell, but I vary our favorite healthy dishes each night of the week ... hope that helps you a bit.
EDIT TO ADD: Since you are living at home, you could eat a light breakfast, take a sandwich & fruit for lunch, and eat one serving of the usual dinner at home. Snack healthy; and do some walking around the neighbourhood for starters, to take a break from your studies in the evening. Up to 60 minutes a day is recommended for maintenance but you can work your way up to that ...
