Hi there. I've been incorporating ACV into my program for Lyme and heavy metal detoxification and I can say that I've definitely noticed some bloat in my lower torso. This is unusual for me because I am rather thin. Through my research and corresponding with one of my friends who is chronically ill as well, my theory is that it depends on how toxic your body is, how well you are able to remove the things that the ACV is aiding in detoxifying and, of course, how much ACV you are ingesting. Hope that helps!
