Well, what you need is a list of foods that you CAN eat ~ not the other way around. You need a solution for the diagnosis ... so here are some of my thoughts (as a person who used to have IBS and must watch the sugar too) ...
YOU SHOULD BE ABLE TO EAT ~
... all lean meats (chicken, turkey, fish, beef, pork, lamb)
... most, if not all vegetables; eat the ones you can
... no-fat dairy and yogurt (ie no-fat/no sugar yogurt/icecream, skim milk; no-fat cheese slices; no-fat cottage cheese; and other NF or low-fat cheeses).
... non-dairy milks like soy milk or almond milk; soy cheese
... whole grains like cereals (check for low sugar) like Oatmeal, shredded wheat, Red River Cream of Wheat, Oatbran, Nutri=grain, etc.
... Brown Rice; Wild Rice; Converted Rice; Basmiti Rice (brown is best; but white is OK mixed with brown).
... All kinds of Beans (you can buy canned but drain & rinse well); you will have to cook them how you like them yourself.
... no or low-sugar condiments like mustard, or make your own salad dressing of oil & vinegar plus herbs and spices.
... tomatoes and plain tomato sauces; tomato paste.
... most whole grain or specialty breads; read the label; and limit your intake.
... whole grain pasta & noodles (ie spagettini, rotini, elbow macaroni)
... eggs (prepared any way)
... canned tuna and salmon; chicken or turkey; packed in water
... low sugar fruits, like all berries
You know, the WW plan allows unlimited fruit and uses a lot of processed foods -- why don't you start there. You will likely have to focus a lot on fresh, whole foods for now; and for extra things, you will have to read labels carefully. Start with the basics, then add in things one at a time and see how you feel ...
EDIT TO ADD ~
I read last night in another thread that you also just started taking BENEFIBER this week -- that alone could account for all your symptoms. Stop taking that for now, and see how you feel ...
