How Brain-Gut-Microbiome Interactions Affect Obesity and Food Addiction.

This topic is more complex than just dietary habits; it involves intricate interdependencies between our brain, gut, and microbiome.

Brain-Gut-Microbiome Axis:
This is a complex network where our brain, gut, and the microorganisms living in the gut communicate. Disruptions in this system can lead to cravings for certain foods and overeating, contributing to obesity.

Hedonistic vs. Homeostatic Eating:
Normally, our body balances eating for survival (homeostasis) and eating for pleasure (hedonism). In food addiction, this balance tips towards hedonistic eating, driven by changes in our brain and gut.

Role of the Microbiota:
The microorganisms in our guts have a significant impact. They can influence our appetite and eating behaviors. For example, they can affect the release of hormones that make us feel hungry or full.

Impact of Diet and Stress:
Our diet and stress levels significantly affect this brain-gut-microbiome axis. Processed, high-calorie foods and chronic stress disrupt the balance, leading to overeating and obesity.

Many people are overweight or obese and aware that losing weight is often difficult. It turns out that food addiction, which influences obesity, is also controlled by bacteria and other microorganisms, including those in the digestive system. In such a case, willpower to avoid eating may not be sufficient.

So, what can you really do to positively impact your digestive system, the microorganisms living there, and your body weight? The simplest method is to stop feeding harmful microorganisms and start nourishing those that positively affect you. Harmful microorganisms feed on digestible carbohydrates. Beneficial microorganisms feed on carbohydrates that are not digestible by the body, such as fiber. So, if you eat fewer digestible carbohydrates like starch and more fiber, you will stop feeding harmful microorganisms and start nourishing beneficial ones. These beneficial microorganisms will produce substances that positively affect your mood and health.
