Decreasing gluten, and, going GF, are two different things. I eat lower gluten because I seem to have some gluten sensitivities, and I take a gluten enzyme when I choose to consume gluten, to help my body to process it.
You said that your doc advised you just to decrease gluten? That is much easier than going 100% GF. And, yes. Start by eliminating breads and pastas. And crackers, any breakfast cereals with wheat or barley, etc. You could also purchase, or make your own GF ones, but, I don't do that. I just choose more options that are already naturally GF. Such as oatmeal or Chex cereal for breakfast. A lot of protein and vegetable meals. Substituting brown rice, corn tortillas, quinoa, etc, when I want a starch.
In restaurants, I order burgers with no bun. (We have a local diner with awesome burgers, and I actually prefer them that way!) Many restaurants that serve a bread or other gluten side with your meal might be willing to substitute a side salad, or the vegetable of the day. For mexican food, I request corn tortillas instead of flour, etc. Most restaurants are really willing to make substitutes if you ask them.
I don't know anything about Jenny Craig food.
I don't have a thyroid condition, but I have MS (multiple sclerosis). Both, I think, are auto-immune diseases. And, gluten sensitivity tends to be somewhat common in those with auto-immune diseases. I used to have intestinal symptoms (ie: diarrhea, etc) when I consumed gluten. They are very rare now, with reduced gluten and the use of gluten enzymes. I choose to consumer gluten approx 3-4x per week. Many average people likely eat gluten 3-4x per day. I don't miss it, since I have not needed to give it up completely. And, white flour products, particularly, seem to make it more difficult to lose weight, so decreasing gluten has had an added benefit for me (made weight loss easier.)
Best wishes in your dietary changes.
