I'm sitting here drinking an Ensure and I came across your post. I'm the biggest fan of an all-ensure diet. I'm in complete remission now after several months of ensure.. no symptoms at all. I drink 6 ensures a day, plus protein shakes, lift weights and get lots of cardio. I've just started HMB/glutamine supplementation too. As for real food, I go out for dinner once a week, and every day I have an extra large coffee and sometimes a non-Ensure meal. I stay away from things I've known to bother me including pork, animal fats (particularly sausages and bacon), popcorn etc. But other than that I don't think of it.
Many months ago I read some scientific articles stating that an Ensure diet (100% ensure and water mind you, no cheating) was almost as effective as prednisone at inducing remissions. So I have been drinking it ever since and I'd say it took about 6 weeks for the symptoms to disappear.
Today I have one bowel movement every morning, no discomfort or blood or anything, no stomach aches, my bloodwork is normal (C reacive proteinn and sedimentation rate etc), and I feel great. My doctor told me to start getting off Ensure but I don't see the point. I really like the taste and convenience and the knowledge that I'm getting a lot of nutrients that my old haphazard diet was missing. I suppose one could argue the $300 per month or whatever for ensure and protein shakes is expensive, but I''m not buying any groceries for myself so that offsets a good chunk of that cost.
I'd highly recommend it to anyone who is going through hell, but you have to stick to the all-ensure diet religiously for at least 6 weeks. If you cheat even once and the food you eat is something that triggers a flare or aggravates your symptoms, you'll give up on something that might have otherwise given you relief...
