In the field of intestinal flora, there is a bad atmosphere, that is, whether in academia or industry, there will be some people who excessively exaggerate the importance of intestinal flora, and even advocate that the microbiota is omnipotent and can cure all diseases. What's more, they must say that they are microflora, think that people are dominated by microorganisms, and even say that improving the intestinal flora will help fight corruption and promote honesty. All kinds of outrageous arguments have led to the entire intestinal flora field still being denied and ridiculed from time to time.
Indeed, the role of intestinal flora is beyond imagination and has a non-negligible role in health, but it must be strictly limited to digestion, nutrition, and metabolism, and cannot be used as a panacea key to solving health problems.
From the most simple point of view, there are about 78 kinds of organs in the human body, each of which performs its own duties and is almost indispensable; no matter how important the intestine and the microflora in it are, it is impossible to replace them one by one, but can only do their own duties in the complex intelligent machine of the human body.
In fact, the gut microbiota is just one element of health. The journal Science published an interesting and meaningful article on October 7, 2016, which not only focused on type 2 diabetes, but also made a systematic analysis of the reasons why you may be concerned about why you are fat.
The article says that about 70% of the reason why a person is fat is because he is born fat, which is determined by genes and inherited from his parents, and only the remaining 30% is determined by environmental factors. There are many environmental factors, including diet, energy expenditure, the effects of early life, gut flora, and other factors, and if you look at it in detail, you need to include total calories, macro/micronutrients, food processing, basal metabolism, exercise, sedentary lifestyle, ambient temperature (well, cold is a little slower, you gain weight slowly), your nutrition and medications while you are still in your mother's womb and after birth, as well as your birth style, sleep status, and environmental toxins, and so on.
See, the gut microbiota is just one of the factors. While there is no exact numerical scale to describe their impact, it should not be a particularly large number.

Each person is an independent ecosystem, which means that the role of the gut microbiota in health is individualized. This also means that the same intervention can be very different for different people. For example, if you eat some probiotics, some people will lose weight, some people will gain weight, and some people will be useless, which is actually normal.
To understand the role of the gut microbiota more accurately, we also need to look at them from the perspective of "mutual cause and effect" between them and people and the environment. Human genes, diet, exercise, drugs used and even living environment will affect the composition and function of the intestinal flora, which in turn will participate in all aspects of human health.
The intestinal flora is both a "effect" and a "cause", knowing that they are one of the "causes" of health, it is even more important to know the "causes" behind this "cause", especially those "causes" that you should change the most - such as diet, exercise, hygiene habits, etc. If you want to be healthy, you should start with a healthy diet and moderate exercise (don't be sedentary), that is, keep your mouth shut and open your legs, which may be the way to go.
In this way, there will be a vibrant, healthy intestinal flora, so that it can be maximized into one of the healthy "environmental factors", and then together with other factors, let these 30% work hard to PK the 70% of the genetic factors, and you may have a chance to win the battle against Chubby.
In a word, it is necessary to know the strength of the intestinal flora, but also the limits of their strength, and most importantly, why they are strong.
