We have confirmation that weight loss also depends on our intestinal bacterial flora.
Having some gut bacteria promotes weight loss.
On the contrary, not having those bacterial strains or having few of them makes it difficult to lose weight even if you follow a weight loss diet.

Confirming the importance of intestinal bacterial flora in weight loss is a study previewed at the Nutrition Live Online 2020 event, a virtual conference created by the American Association for Nutrition .

SOME INTESTINAL BACTERIA PROMOTE LOSS, OTHERS HIND IT

Among the many studies previewed, I was struck by this one of the researchers at the Johns Hopkins Bloomberg School of Public Health, who studied the effects of the same diet on a sample of people. The researchers noted large differences in the weight loss results achieved by the participants. After six months of dieting, in fact, only 12% of a sample of 36 overweight or obese subjects lost more than 5% of their body weight, which was the requisite required to understand whether the diet was effective or not. A good part of the subjects lost only a couple of kilos, some did not lose weight at all.
How can this difference be explained?

According to the researchers, those who lost weight had different intestinal bacteria or in higher concentrations than those who followed the diet without losing a pound. But which ones?

THE BACTERIA THAT PROMOTE LOSS

The intestinal bacteria that promote weight loss are essentially those that produce the most butyric acid and succinic acid in the intestine.
I had already talked about the importance of butyric acid for having a healthy metabolism. Today it turns out that the production of these two fatty acids is essential in promoting weight loss. There is a but. And that is, not all people have these bacteria or have them in the right concentration.
The introduction of foods that contain it in small quantities or the integration can be useful ways.
Butyric acid is found in butter, in aged cheeses such as Parmigiano Reggiano, in non-skimmed dairy products and in whole cow’s milk, in blue cheeses. Potato starch has also been shown to increase intestinal production of butyric acid. Succinic acid is found in broccoli, rhubarb, beets, meat and cheeses.

The MD Mediterranean diet could be the solution in people who do not lose weight with a normal diet, because it is richer in dairy products and cheeses. Otherwise there are supplements on the market.
For example, supplements of Gaba (gamma-amino butyric acid) or with sodium butyrate.
