Bacteria that lose weight for us: scientists on the new organ

Scientists are increasingly saying that the microbiome - the collection of bacteria living in the human body - plays a much more important role than previously thought. Today it is already called a "forgotten organ" that affects not only digestion, but also metabolism, immunity, mood, and even the ability to lose weight.

Bacteria in the stomach - not enemies, but allies

Trillions of microbes live in the human body, most of which inhabit the intestines. Recent studies have shown: people with excess weight and slim people have completely different microbiome compositions. And it's not just about nutrition, but also about how these bacteria process food, produce vitamins, hormones, and trigger metabolic processes.

Some strains, such as Akkermansia muciniphila or Bacteroides, promote weight loss: they improve insulin sensitivity, reduce inflammation, and accelerate fat burning. Others, on the contrary, contribute to energy accumulation and enhance cravings for sweets.

Microbiome as an organ

Researchers suggest considering the microbiome as an independent organ: it has functions, mass (up to 2 kg), and impact on health. It can even be "transplanted": microflora transplantation from slim donors helped obese patients lose weight in clinical experiments.

Is the future in bacteria?

Scientists hope that in the coming years, personalized probiotics, formulated based on a specific person's DNA, will be able to replace diets and pills. Instead of counting calories - microflora analysis. Instead of exhausting workouts - bacterial balance.

"The microbiome is like an ecosystem inside us. And if properly cared for, it can work for us, not against us," note researchers from Harvard Medical School.
