The Microbiome.
Our Inner Life Force.

The microbiome is a complex community of microorganisms that lives in your gut. It’s made up of trillions of bacteria and other microbes that work together to maintain your health. After centuries of thinking all bacteria are our enemies, science has finally revealed the very opposite; bacteria are our greatest ally and are crucial to our health!

Now that science has uncovered the incredible interworkings and intelligence, yes intelligence, of the powerful gut microbiome, we can bring lasting weight loss and wellness to life.

The Microbiome

Connection to Health
and Weight Loss

Understanding our body’s microscopic control center and why it’s important starts with understanding the profound and far-reaching effects gut health has on overall health. With a direct connection to the brain, the microbiome has the final say on how our bodies work and how we feel.

Metabolism and Appetite

Metabolism and Appetite

The microbiome stimulates the gut to secrete many compounds and hormones that reduce appetite and boost metabolism. One of these compounds is GLP-1, the originator of the booming GLP-1 mimickers in the weight loss medicine market, such as Wegovy and Ozempic. Unlike these drugs, the microbiome produces so much more, including other GLPs to produce a healthy whole, which is greater than the sum of all its parts.

Gut Microbiome and Metabolism

Energy Levels

Energy Levels

A healthy microbiome increases nutrient absorption for better energy production from the food we eat. Its connection to our metabolism also helps to regulate our energy storage and usage for optimal energy levels.

Brain Function and Mood

Brain Function and Mood

The microbiome influences the production and regulation of neurotransmitters, such as serotonin, dopamine, and more. This connection explains why an unhealthy microbiome can cause stress and even depression, as well as affect cognitive functions like focus and productivity.

Immune System

Immune System

A diverse and balanced gut microbiome is essential for maintaining a healthy immune system. It helps protect against pathogens (harmful bacteria, viruses, fungi, or parasites), regulates immune responses, and promotes immune tolerance.

What Determines
Your Gut Health?

Everyone's microbiome is unique and has its own optimal balance of bacteria. This optimal balance strengthens our gut wall and keeps inflammation at bay.

From the moment we are born, our microbiome begins to be affected by its environment and the variables introduced to it — from what we eat to how we feel emotionally.


Calorie counting? Carb-cutting? Fasting? When it comes to the foods we eat, what matters most is giving our microbiome what it needs to operate in top shape. That means more, fiber and probiotics, and far less processed food full of refined sugar and fat.


Bacteria thrive on exercise—especially cardio. Not because it burns calories but because it supports a diversity of bacteria that is crucial to its function.


The gut-brain axis goes both ways. While a healthy microbiome supports your mood, the act of stressing out can directly damage beneficial bacteria in your gut. From stressful life events to ongoing stressors, the gut takes the brunt of it all.


Antibiotics, while sometimes necessary, can wreak havoc on your microbiome, killing off bacteria of every kind. Understanding this, antibiotics should be taken with caution, and always supported by probiotic supplements.
