Stupid IBS

Hugs - IMHO? Just write those days off. Just cannot know what calories you have absorbed that day, you know? And your body is going to need nutrients to help heal up any potential damage, calm down inflammation, and so on, so you don't want to eat too little after a bad day, you know?

Sorry you are having a hard time, though!

Augh i know what you're going through. I have Crohn's Disease, and am trying to gain weight. Because of malabsorption issues, I have to eat about 1000 more calories than what MFP gave me. Inflammation and meds totally screw things up. The good news is that now I have figured out the right amount of food (and kinds of food), plus consistently getting adequate sleep and exercise, I feel so much better. My labs the other day showed that my inflammatory markers reduced significantly to numbers I haven't seen in years.

IBS is easier to treat than IBD, but it is still miserable trying to figure out what works. I hope you feel better soon.

I had issues for 20 plus years and a sensitivity test showed I have a heightened number for casein and eggs. Did an elimination period to see if it made a difference in my health and the persistent diarrhea disappeared. A relevation as this was the first doc to ever suggest something like this might help my overall health. To be clear, this isn't an allergy, just a low tolerance. I can eat some, but too much more me sick.

My IBS is "in remission" at the moment, but I found the best thing for my bad days was to drink plenty of water and eat really plainly, like rice, steamed veg, peanut butter sandwich, etc. I also took loperamide if needed.

As far as calorie counting, I'd say just stick to your goal, and if you find that you're losing too fast, increase your calories.
