The lack of energy rings a familiar bell to me. I started feeling tired after I ate several years ago. Actually, not just tired, but wiped out. Exhausted. I tried changing all sorts of things related to my diet, but finally saw a nutritionist and doctor who were able to run some tests. A stool test and a genetic test confirmed Celiac disease--meaning my body was having an autoimmune reaction to eating wheat, barley, rye, and (non-certified gluten free) oats. Celiac disease/gluten intolerance is NOT an allergy and will not show up on a typical food allergy test. If you're having fatigue after you eat, I cannot recommend strongly enough that you see your doctor and specifically request a stool test and genetic test for Celiac disease. (There's also a blood test, but it doesn't work for everyone.) You may find you have it--1 in 133 of us do, but in America 95% go undiagnosed. Or you may find you have its lesser form, gluten intolerance. The only cure is to completely 100% avoid gluten. It is tricky, but well worth it in terms of energy. I also suggest that anyone who has Type I diabetes, Crohn's, colitis, lupus, or general digestive issues get tested for Celiac/gluten intolerance as well (via stool test if at all possible.) The tests are painless and if you find out you do have it, other weird symptoms like fatigue and joint pain may disappear if you eliminate gluten. Celiac disease and gluten intolerance are genetic, so if you get tested and it's positive, your family members should test, too, even if they have different symptoms or no symptoms.
