I made it on a liquid diet for almost 2 years with partial obstructions.... here's what I ate maybe it'll help you.
vanilla yogert, frozen fruit (mango is easy on you), some banana, rice protien powder in the blender.... I used vanilla rainbow light powder.
I also made soup, chicken broth, potatoes, and whatever other veggies you can handle -- and then pureed it into smoothness.
I hardly lost weight, but I'm a non-typical crohn's -- i don't have to deal with the D, I get the opposite. But I had adhesion surgery after 2 years and the stricture mostly went away so I can eat regular food. When I was partially obstructed like you I could do the smoothies -- but not the soup. These "recipes" are also gluten free.
hugs, hang in there.
