Life happens. Somedays you'll have more time to have an elaborate breakfast for yourself. Other days it might be a little bit quick. I think it's just important to have something nutritious and take the time to eat it. If timing your food is difficult maybe trying to meal prep every few days so that you have a great balanced meal ready to go more often.
If I had the time I'd prefer to have a big breakfast with plenty of protein, but I opt for a small, carb based breakfast because I'm always running late
It depends on how much time I have. I keep hard boiled eggs in the fridge that are ready for when I need a quick healthy breakfast and have yogurt at work. If there is time, I scramble eggs with pre-cut onions and prewashed spinach.
I always eat a big bowl of oatmeal with soy milk, peanut butter, ground flax seeds and a small banana which sums up to about 1000 calories.
When I can, I definitely try to make time for a filling and healthy breakfast. However if I don't have much time, even some cereal and a piece of fruit like a banana or apple is better than nothing!
It really depends when I have to get up for work. I will not have a big full breakfast at 3am, since I'm not hungry then and rather sleep 30 minutes longer. But I do make time in the evenings to prepare something nice for like 7 am or so. When I have time in the mornings I take it to have a nice meal and be good to myself after I worked out.
Usually a vegetable, yogurt, and fruit smoothie of some sort. When time allows, eggs and a meat.
