"Just think fresh only and no dairy, no gluten, no fats, no sugar"
That just leaves protein? What are your calorie sources?
Long-term, I agree with seeking out a refined diet that works for you. Your IBD doctor may even test you for things like celiac's disease.
Short-term, if I could tell my recently diagnosed self how to handle this gap in time, I would say to start with a liquid diet that has calories, even clear liquid for a day if necessary. If you can, log your daily food/calorie intake, number & consistency of BM's, and notes about
cramping/pain/etc. These will be among the questions your GI asks, and it helps to have some detailed notes instead of a general answer. I also find that keeping a log that I will see pattern myself in how I respond to things I eat. This can help with your long-term dietary plan.
Gatorade helps replenish fluids lost with D and provides some calories. Ensure or Boost type milkshake flavored products would be a good short-term calorie fix (250 cal per oz bottle), also loaded with vitamins. My doctor advised me to start with 1 the first day and gradually increase to no more than 6 a day. (They are expensive, but they are meal/food replacements.) I found the vanilla and strawberry to be decent tasting if chilled in the fridge. Other liquid options include cream-based soups (w/o chunks of solid food), ice cream, pudding, yogurt, etc.
Then, even if that helps me feel better after a day or two, I'd stay conservative until the doctors appt. I'd move to a very low residue diet, chewing everything well. I'd stick to things that required very little digestive activity or irritation. Certainly avoiding fruits and veggies. I'd start with crackers, toasts, eggs...things like that. Graduating to overcooked noodles. Tender baked fish or chicken can also be OK in small doses. Even by the 21st, I probably would consume no less than 1/2 my daily calories via liquid foods.
It helped me to stick to small frequent meals/snacks, and avoiding any large quantity meals. I had to get over the "clean your plate" or "don't throw food away" mentality.
I was having a lot of pain and flare related issues in the latter half of 2010. Was told early in 2011 that things were getting too narrow in my strictured area to continue without a bowel resection. Maintaining a low residue, high-liquid diet helped me feel better in that time waiting to see the how's and when's of my surgery.
And I didn't really have many "flashing" episodes, but I did have elevated pulse rates and blood pressure rates throughout this time of partial obstruction. The area of my bowel preceeding the stricture was dilated. My normal, low pulse and BP rates have returned post op.
