Advice for students!

The losing weight part is simple. Take whatever you are eating now and eat less of it. It's not easy, but it is simple. Get a food scale, some measuring cups, and use the very thorough MFP database. Enter everything you eat and don't go over your goal. You will see results if you are honest with yourself and consistent with your logging.

The healthy part will be a little bit more difficult and significantly more personal. There are plenty of opinions and research describing how you can improve your health. It involves things like more veggies and protein and less sugar. It will require more work on your part to find, store, and prepare these things. Or more cost to buy them ready made.

I eat fruit, vegetables, and yogurt every day. I find that I feel better when I eat them and worse when I don't. When I feel worse, I am more likely to eat worse food, and much more likely to exceed my calorie goal. That is how I got fat to begin with.

None of the above includes that benefits and time commitment of exercise.

If there was magic formula to help you, a time deficient student, achieve your weight loss and health goals it would work for most people and none of us would be on this forum. Unfortunately there isn't.

There is lots of great advice on the forums. Search for your specific questions. The best way to start making progress is to start.

Prepackage your snacks for the week. And if you are on the go a lot, try for items that you don't need a fridge for. Buy tiny Ziplock bags or better yet, reusable small containers (e.g., the small round Ziploc brand plasticware) and measure out portions of snacks. For example:
pretzels
yogurt
cottage cheese

Make sure you have enough protein. Cut up a block of cheese into single serving chunks, wrap and store in the fridge for "grab and go" snack. Peanut butter and celery can be cut up and stored in the fridge for a few days. Wrap a little cheese in a piece of lunchmeat. Put a few of these in a single serve container. Make up the packages before you even put groceries away.

Great Ideas!

A lot of good ideas so far! One thing that helped me is taking time at the beginning of the week to make a large batch of soup, etc. that will last me the remainder of the week. I can eat the soup as a meal, or as the side to a more quickly-to-prepare sandwich.

Drink water! It's free, and it's great for you!

I know for me, mindless snacking during studying happens, but just swapping out something high in calories with fresh fruits, veggies, and other healthy things definitely helps
