In my case, I got tested with a really high end high sensitivity test for gluten/celiac and don't have it. I do have metabolic syndrome and glycogen storage disease marked by hyperinsulinemia and severe steatohepatitis, which is finally beginning to be investigated and taken seriously due to links with liver cancer and other diseases. Metabolic problems can be very serious. In my case, due in part to heredity, my liver does not metabolize glucose or carbs properly and does not burn fat well. Eating a low fat diet causes me to store more fat since that is the body's response to fat starvation. I must eat a moderate to high fat diet, almost like the ketogenic diet, in order to lose weight, and must avoid as much carbs and sugars of all kinds as I can. Many diabetics have the same problem, where it is the liver, not the pancreas, causing issues. Eventually, the increased demand for insulin will send me into type two diabetes full-blown because the pancreas will just burn out. I take metformin, which helps the liver to deal with sugars better and follow a special diet.
Diabetics are beginning to take issue with the national diabetes foundation's recommendation of a "heart healthy" diet, as it contains lots of carbs and little fat, which causes those of us with fatty liver, once called "diabetic liver", to get much worse. I was on a very low and low fat diet for many years after the onset of my fatty liver as they thought it was a good thing, and even put on the drug now called Alli, all of which caused significant worsening of my liver disease to the point that I'm one step from end stage liver disease. I have stopped the progression of my liver disease through Metformin given to me by my hepatologist, and an Atkins type diet with moderate fat intake and significant protein, etc.
So one diet might be okay for one, and very detrimental to another.
