Weight gain is often seen as a direct result of lifestyle habits like overeating or lack of exercise. However, not all cases of excess weight are tied to body fat. For some people, chronic inflammation caused by food sensitivities may mimic or contribute to weight gain.

Kanikka Malhotra, a clinical nutritionist and diabetes educator, suggests using the IgG Food Sensitivity Test to identify potential inflammatory triggers.

What is the IgG food sensitivity test?

The IgG food sensitivity test measures Immunoglobulin G (IgG) antibodies in your blood to detect potential food sensitivities. The test evaluates your immune system’s reaction to specific food antigens by identifying elevated IgG levels, which may indicate a sensitivity or intolerance, Malhotra explained.

Elevated IgG levels do not necessarily mean a food allergy but a slower, more subtle immune response. These sensitivities can lead to gastrointestinal issues, chronic inflammation, and systemic discomfort, making the test a helpful tool for uncovering hidden triggers.

How does the test link to inflammation?

When your body reacts to foods it’s sensitive to, it produces higher IgG antibody levels. According to Malhotra, these antibodies can activate the complement system, a part of your immune response. This triggers an inflammatory reaction, which, when chronic, can manifest as weight-related symptoms, she explained, such as:

Fluid retention due to inflammatory cytokine release
Increased fat storage caused by disrupted insulin signaling
Heightened appetite and cravings, as inflammation impacts hunger hormones like leptin

Malhotra emphasises that addressing these sensitivities can reduce systemic inflammation, helping with weight management and improving overall health.

How to use the results?

After taking the IgG food sensitivity test, consult a healthcare professional to interpret the results. Adjusting your diet to exclude identified trigger foods may help reduce inflammation, alleviate symptoms, and potentially lead to improved weight regulation.
