I agree that for most people who aren't trying to manage celiac disease, gluten-free is another trend that's not really going to make them thinner and better-looking. A friend from HS made an interesting observation, though: she doesn't have celiac disease but claims that she feels much better on a gluten-free or low-gluten diet. When she went on a trip to Slovenia, she found that the baked goods there didn't aggravate her system like the ones here. Count me among the Food Conspiracy Theorists if you will, but I wouldn't be surprised if it were due to less processing and simpler ingredients in the food in Slovenia.
Count me among the "gluten insensitive" group, which is much larger than those with Celiac disease.
After months of feeling bloated after eating pasta, and having a "foggy head" in the morning after eating wheat cereal, and various other stomach cramps that I could trace to eating white bread, I gave up gluten as a test. My weight dropped from 128 lb to 124lb in four days, and eventually settled at 122-123 and was very steady.* My ankles stopped collecting fluid and my tennis elbow issue stopped hurting so much. My thinking was clear and more focused. I have no doubt that I can trace my "feeling better" overall to giving up gluten. I may eat a tiny bit now and then, but no way would I eat wheat cereal, wheat bread, or wheat pasta when there are so many great options.
Anyone in the Southwest can find Canyon Bakehouse's bread in the freezer at Whole Foods and other supermarkets, and when it's toasted you can't tell it's gluten free.
I would suggest that anyone who feels abdominal bloating that they can't explain, or a foggy head and fuzzy thinking, go on a strict gluten-free diet for one month. You might be surprised.
I was encouraged to try this test after reading "Wheat Belly" book that I borrowed.
* I should add that before this test I would have trouble losing even 1 pound, and could only lose any weight by following a strict diet and exercising heavily. So 4 lbs in less than a week was a clear indication that something was amiss. I had been around 128-130 for a few years.
