This may surprise some people.
I'll let you read this article: all I know is going gluten free after being diagnosed with a celiac related skin disorder, has massively improved labs in a very short time and explained years worth of severe skin problems, food allergies, digestive problems, and vitamin deficiencies my recent doctors have discovered despite food intake. I do not know if this will take any more weight off-it has taken some off, it seems to have absolutely killed cravings for carbohydrates and waking up everyday, not worrying about itching to death is a nice change. It is not an easy or cheap diet to follow but the difference in how I feel is night and day. Read on about the celiac link to autoimmune disease and much more.
Another disorder commonly associated with celiac disease is malabsorption, which can also lead to malnutrition. When someone with celiac disease eats foods that contain gluten it results in damage to the surface of the small intestine and destruction of their nutrient-absorbing villi. This can lead to leaky gut and an inability for them to absorb vital nutrients from their food. By continuing to eat foods containing gluten, eventually vital organs including the brain, thyroid, liver, kidneys—essentially any organ that depends heavily on nutrients—will be starved, which will leave them susceptible to other diseases and conditions. I personally experienced brain malfunctions, gall bladder problems, and was diagnosed numerous times with an under-active thyroid. Naturally treatments for this proposed thyroid condition didnt work because their true cause had not yet been found. At one point a doctor asked me to consider the idea that my obesity was the result of my bodys attempt to cope with malnourishment4. This phenomenon is similar to yo-yo dieting, where dieters who have deprived themselves or proper nutrition for too long gain weight at faster rates than non-dieters after they resume eating normally. I always thought that I had fallen victim to yo-yo dieting, and that I had dieted myself into a permanent state of obesity. I now understand that it was because I had undiagnosed celiac disease, and my body was actually malnourished.
