Map your Gut and Master your Metabolism

Dr. Juliet Ghodsian, ND

We are often told that diet, genetics, and endocrine balance are the primary factors that determine our body weight set point.  However, there is another often-overlooked variable that can play an important role in maintaining your body weight.  This is your personal collection of microorganisms, or your Microbiome.

How could the microbes in our gut affect our body weight? When we eat food, our digestive system breaks it down into small pieces. Only the smallest pieces get absorbed into our blood. The rest is eliminated as waste material.  This means that a large part of what we eat never leaves our intestinal tract. The bacteria living in our gut help to break down these leftover food particles. Some bacteria will release different metabolites or chemicals during this process, which can then be absorbed into your bloodstream. Increasing levels of these compounds are associated with higher body weight set points. To test this theory scientists in one study transferred bacteria from the guts of two strains of mice — one that naturally becomes obese and one that naturally stays lean — into a third lean strain raised from birth to have no gut bacteria. Gut bacteria transferred from the naturally obese mice made the germ-free mice become fat, but gut bacteria transferred from the naturally lean mice kept them lean. From this we can theorize that changes in your gut microflora balance could potentially be the cause in a change in your overall weight or ability to lose weight

If you are struggling with your weight, consider evaluating your microbiome and the role it could be playing as a contributor in your overall weight set-point.

The most accurate way to assess and quantify you microbiome is to use a test that can detect and identify the organisms based on the presence of their DNA. The GI Map Stool Test utilizes a PCR technology to provide a DNA based stool test. This technology has high sensitivity, specificity and a rapid turnaround. The GI-MAP Stool Test measures opportunistic organisms, normal flora, virus, fungi, parasites and antibiotic resistance genes. The GI Map Plus also checks your immunologic markers for GI health and function including SIgA, Elastase, Calprotectin and Anti-gliadin testing. If there are elements of inflammation that are a part of your health profile, you may want to consider this more comprehensive test.
