Why does the gut microbiome associated with obesity increase?

Preventive studies abroad have extensively investigated the desired composition of the gut microbiome, how it’s gained, and how it’s lost. A deteriorating microbiome generally predicts other gastrointestinal disorders.

The primary reason for this deterioration is the continuous reduction and simplification of dietary fiber in our nutrition. In the Stone Age, fiber consumption exceeded 100 g/day. A few years ago, this figure was about 13 g in Finland, and it has further declined since then. There are 10 different types of fiber, each fostering slightly different microbes. Microbes thrive on a diet containing 50 g of fiber per 1000 kcal, sourced from various plant groups such as seeds, fungi, berries, herbs (including health-promoting spices), fruits, vegetables, and 100% whole grains. Plant-based fibers are entirely essential for both microbes and human health.

Another contributor to gut-related illnesses is the growing prevalence of harmful foods (fast food, sugary beverages, sweets, pastries, alcohol, heavily processed additive-laden ready-to-eat meals) as the primary source of energy. Fast food outlets and regular restaurants predominantly sell fast, or junk food, the harmful effects of which are beyond doubt. The use of refined grains has also risen in recent decades.

Other factors that damage and weaken the gut flora or induce gut inflammation include linoleic acid, i.e., omega-6 structured seed oils, many medications (e.g., anti-inflammatory drugs, antibiotics), and certain residues from agriculture like glyphosate and potentially hormone residues in imported meat.

Reduced physical activity, which also contributes to increased stress, along with the increasingly common hormone imbalance (including thyroid), further contribute to disruptions in the gut and microbiome.

This broad lifestyle-related phenomenon increases inflammation of the intestinal surface and nerve cells (200-500 million) and gut “leakiness,” meaning the absorption of harmful substances through a damaged gut lining (epidermis) into the body, leading to a decline in the microbiota. This, in turn, leads to obesity, memory disorders, fatigue, weakened immunity, and more.
