Weight loss is a common health goal, but it is difficult to achieve and even more challenging to maintain. The truth is that weight loss is more than just eating fewer calories and exercising more; everything in the body is connected. When it comes to weight loss, we often overlook the role of hormones, environmental factors, food sensitivities, inflammation, and the gut microbiome – our topic for today. 

‍

Keep reading as we unpack the complexity of weight loss and the role of gut health as a root cause. We’ll explore:

• The gut microbiome and metabolism 
• The gut health-weight loss connection
• How inflammation affects gut health and weight loss
• How to improve gut health – the best foods for gut health
• Improve the gut microbiome for metabolic health

Gut Microbiome and Metabolism Explained

What is the gut microbiome? The gut microbiome includes the trillions of microorganisms, including bacteria, and their DNA that inhabit the digestive system, primarily the colon. We have a mutually beneficial relationship with our microbiomes: we provide the microbes with a home, and they provide us with digestive support, nutrients, and many avenues of communication. 

‍

The gut microbiome influences digestion and gut health, obviously, but also much more. A healthy gut microbiome promotes overall health, including metabolic health. This means a healthy metabolism where we can effectively utilize the fuel from our food, maintaining and optimizing body composition, blood sugar, and other essential body functions.

How Gut Health Affects Weight Loss

To understand the gut-weight connection, we first need to understand the gut-microbiota-brain axis. You may be familiar with the gut-brain axis, the bidirectional communication between the gut and the brain, but it’s more complex. The gut microbiome plays an intermediate role in this communication. 

‍

Intestinal microbes and their metabolites (the compounds they produce) communicate with the brain and play a role in regulating metabolism, fat storage, appetite, and other factors determining body composition, energy usage, and, ultimately, weight. 

‍

Therefore, efforts to improve gut health and microbiome gut bacteria balance and diversity can shift metabolism in beneficial ways, helping to promote weight loss.

Inflammation’s Impact on Weight and Gut

Much of the body’s immune system resides in the gut; it’s the first line of defense against pathogens (from food and water) entering the body. This also means that the gut has the potential to be a significant source of inflammation, which over time contributes to weight gain and makes weight loss more difficult. 

Much of the body’s immune system resides in the gut; it’s the first line of defense against pathogens (from food and water) entering the body. This also means that the gut has the potential to be a significant source of inflammation, which over time contributes to weight gain and makes weight loss more difficult. 

Sources of gut inflammation can include infections, such as pathogenic bacteria, yeasts, or parasites living in the digestive tract and altering microbiome function. Eating foods you are sensitive to, along with additives, chemicals, and toxins also causes inflammation. 

‍

One step in how to fix the gut microbiome is removing foods, pathogens, and other sources of inflammation. 

‍

Diet Changes to Improve Gut Health 

Your diet significantly influences your gut microbiome; changing your diet changes the gut microbiome and your health. Research shows that targeted probiotics and prebiotics can favorably alter the gut microbiome to promote weight loss. 

‍

The best gut health foods contain beneficial microorganisms to seed the gut microbiome (probiotics) and food to feed the beneficial microbes (prebiotics).

‍

Foods for gut health include probiotic fermented foods, including:

• Yogurt
• Kefir
• Miso
• Tempeh
• Sauerkraut
• Kimchi
• Apple cider vinegar

‍

Prebiotic foods are the second part of a gut health diet. They include fiber- and polyphenol-rich plant foods such as:

• Berries
• Green bananas
• Dandelion greens 
• Sunchokes
• Artichokes
• Garlic
• Leeks
• Asparagus
• Oats
• Jicama
• Flaxseeds

Restore Gut Balance for Metabolic Health 

At The Fork we offer functional gut microbiome tests and personalized protocols to address imbalances affecting your metabolism and weight. We suggest targeted gut health supplements, probiotics, an elimination diet, and lifestyle strategies. Ultimately, the best diet for gut health is the personalized one for you.
