Brief summary
This study assessed the effect of an IgG-mediated food sensitivity test in combination with a food elimination diet on body composition and secondary outcomes in people who were overweight.
Detailed description
This study looked at foods that stimulated IgG food antibody production, which may play a role in certain conditions, such as irritable bowel syndrome, obesity, type I diabetes, and migraine headaches. Using a proprietary blood test, the Immuno Bloodprint, to determine which foods stimulate IgG food antibodies in each person, this study detailed a personalized list of reactive foods that stimulated such antibodies for each participant. The participant was then advised to eliminate as much as possible the reactive foods for 90 days.
Interventions
Subjects were provided with the test results and an individualized dietary plan based on replacing reactive foods with non-reactive foods as replacements per the Immuno Bloodprint results.
