If you don't have much time to eat during the day, then it sounds to me like you need to be focusing on calorie-rich / nutrient-rich foods every time you can eat.
Are you hungry in the mornings? If so, then would you have time to have your "major" meal then? Maybe shooting for a higher protein meal of 500-600 calories for breakfast (omelet, or frittata, or quinoa, or casserole, or any traditional "dinner" meal) would give you a better start on the day.
Do you have time to nibble at a snack bar during the day? If so, then you could make some at home with nuts, dried fruits, hemp or soy protein, gluten-free oats, pumpkin or banana, and anything else that you like so that it's got both nutrients and calories. One or two of these at 300-400 calories each would be a quick and easy addition to the day.
A couple of servings of home-made trail mix (nuts, dried fruits, chocolate, etc.) might be enough to get you where you need to be, and can be eaten a bite here and there as you have time.
I'm not a fan of "drinking calories" personally, but there are some great smoothie recipes around that could work for you if that fits in to your schedule better.
Hope you figure out something that works for you!

Afraid of a colonoscopy? Believe me - they are much less frightening than surgery and chemotherapy.
Colonoscopies allow polyps to be removed before they can become cancer, or let cancers be found before they are too widespread. If you are 50 or older, or have any symptoms, please don't let fear stop you from covering your butt.
