I have been lurking on this site for a while and find it a very interesting and valuable source of information and research topics as a uni student.
This is not so much a question but a topic which I have not found much info on this site and would like to spark some discussion.
I am currently doing some research on IgG food-specific intolerances and their detrimental effect on metabolism, fat loss, and also most likely on lean muscle gain.
These are not the type of symptoms associated with acute (IgE) allergies that most people think of (eg peanuts etc) but a more long-term chronic and systemic inflammation. There is quite a bit of evidence suggesting that perhaps most people have some kind of immune response to at least some food in their diet.
This immune response results in complex inflammatory mechanisms. Think of it as constantly ingesting a pathogen(eg a bacteria or virus), creating a constant state of inflammation. Symptoms may be mild and not cause reason for seeing a doctor - eg tiredness, bowel disorders, weight loss/gain, joint pain etc
There is a lot of evidence that identifying and eliminating/limiting these foods can reduce such symptoms. There is also evidence that such an inflammatory response increases glucose resistance and alters metabolism and therefore would have a profound effect on body composition.
There are a lot of experienced nutritionists and researchers on here so I wonder if anyone has heard of this or anything similar before or if it makes sense?
