Unlocking the Power of the Microbiome for Metabolic Well-being
A decade ago, most people didn’t give the microbiome a second thought. Today, the microbiome is nearly a household term. In fact, scientists now know the microbiome plays an important role in human development, immunity, and nutrition. Data shows that the risk of diseases such as diabetes, rheumatoid arthritis, and multiple sclerosis may be partially impacted by gut bacteria. It may not be surprising, then, that the microbiome may also play a role in weight gain and obesity.
What is the microbiome?
The microbiome is a group of trillions of microorganisms—including bacteria, fungi, and viruses—that live in the gut.
Everyone’s microbiome is unique, partially determined by DNA and also by the microorganisms received during birth and via breast milk. Later in life, a person’s microbiome can change due to nutrition and environmental exposures, such as medications. These changes are sometimes harmful, as the risk of certain diseases and conditions can increase.
What’s the connection between the microbiome and obesity?
The makeup of the gut microbiome appears to be a key player in determining how a person responds to weight loss efforts. One recent study showed that participants with higher concentrations of beneficial gut bacteria at baseline experienced more weight loss when placed on a weight loss program. This is likely due to the direct impact the gut microbiome has on metabolism and fat deposition.
The types of bacteria living in the gut also play a role in blood sugar control. In fact, an abundance of certain strains of bacteria has been linked to the development of glucose intolerance and type 2 diabetes. On the other hand, a diverse population of microorganisms appears to have a protective effect. Keeping blood sugar under control prevents hormonal disruptions and insulin resistance which are known barriers to weight loss.
