Hi, I completely understand what you're going through! I've had this issue for about 6 months and I can't tolerate any fat whatsoever. I was diagnosed with malabsorption because of constant steatorrhea, but pancreatic enzymes were normal like yours. Doctors have no idea what's wrong, are very slow, and are not helping me at all. I see all of my appointments as a huge waste of time and money, so I'm forced to be my own doctor to figure this out.
I have searched hours upon hours, reading books, medical journals, and internet searches, and cannot find much information in regards to fat intolerance. However, anything that I find is pointing to a problem with the liver. So, when you go to your next appointment, tell them that you want them to check your liver completely. I will be doing the same in a few weeks.
In my opinion, the best thing for you too do it cut out all fat, but take an enteric coated fish oil suppliment so you can still get some good fats into your diet. Renew Life has a product called Norwegian Gold and it contains lipase to digest the fats inside the capsule and it bypasses the stomach and liver. I take two of those a day and have no issue with them. If I took fish oil in liquid form, I would feel sick, so I know that this suppliment will be okay with you also.
If chicken breast is bothering you, you can try boiling it, and that should help get rid of most of the fat content. I was ok with chicken, but only if it was boneless, skinless, and boiled for an hour or so. Another great protein source is cold processed whey protein isolate. It contains no fat, lactose, or casein, so it is very easy to digest and very good at increasing the immune system and adding muscle to the bones.
You should be able to make up for the calorie loss by eating more carbohydrates like whole grain bread (not refined) and potatoes, and 0% fat yogurt (made by Stoneyfield Organic), and other high calorie foods like bananas and honey (unless you have a candida problem).
I hope this helps
