Well it varies A LOT since I'm a law student, I sometimes get too busy to eat proper food and snack on very unhealthy stuff like candy bars, ice cream, chips etc.

But that's usually just for the midterm or finals week, other times eating goes something like this:
Breakfast: I usually have a veggie omelette or oatmeal with skim milk and nuts and fruit as topping -usually bananas, blueberries and walnuts. I always have fresh orange or grapefruit juice to go with it, it's just a childhood habit for me. Sometimes I'll have peanut butter or avocado on toast.
Snacks: I'll have a giant cup of coffee with skim milk and some fruit (bananas are go to) whenever I'm hungry until lunch. I usually snack just once between breakfast and lunch though.
Lunch: This varies a lot more since I'm always out for lunch or at school. I usually get a salad with tuna and eggs or chicken and cheese. I might have grilled chicken with grilled veggies as a side too. If I'm super busy I'll get a grilled cheese sandwich on the go.
Snacks: I like nuts in the afternoon: sometimes in a trail mix with dried fruit or just 1-2 handfuls of almonds. I also usually have an organic protein bar made with dates and almonds, no added sugar. I also have another piece of fruit sometimes.
Dinner: If I'm eating at home, I get to have salmon or a nice steak with a side of veggies or salad. If outside, I usually go for sushi or if at a place that doesn't serve it, I go for the biggest salad they have, usually with beef or chicken strips. And I order crispy sushi rolls which means it's fried and battered and full of sauce - I can never feel full with sashimi alone though snacking on some edamame beforehand does keep me from eating too many pieces.
Snacks: I snack the most at night. I can never stop eating after a certain hour, it's just not doable for me, if I'm awake, I eat every 2 hours or so regardless of how close it is to bed time. I eat Greek yogurt with berries, another serving of fruit, maybe more nuts and lots of green tea. Add coffee and dark chocolate if it was a busy day.
Also if I worked out that day I have a giant glass of fresh fruit and veggie juice after workout or a protein shake if I worked out for long, like 2 hours.
I guess main problems are I eat too often, I eat at night and I have a sweet tooth and caffeine addiction that is manageable on regular days but they cannot be ignored on busy days/exam weeks.
