New Study Shows that a Low-Calorie Diet Can Improve Your Immune System!

According to a new scientific paper published in the journal Microbiome, reducing your calorie intake as part of your diet not only delays the development of metabolic diseases but it even has a positive effect on one’s immune system!

This is because of altering the gut microbiome which is able to slow down the immune system’s deterioration as a result of aging.

The gut microbiome refers to all of the microorganisms and bacteria found in the digestive tract and can influence both the metabolism and immune system of the host.

That being said, obesity can increase the risk of developing high blood pressure, suffering a heart attack and even type 2 diabetes mellitus.

In addition to that, it can lead to inflammation in the body that can weaken the immune system by accumulating specific memory B and T cells, a process known as immune senescence that is age-related.

Thankfully, obese people can delay the development of certain metabolic illnesses such as type 2 diabetes by following a low-calorie diet.

But for the first time ever, the research also proves that a low-calorie diet is also a big help for the immune system but it is still not clear how the positive effects happen and what function the gut microbiota plays in the whole process.

As for how the study was conducted, they first looked into how a low-calorie diet amounting to 800 calories every day for a total of 8 weeks influenced the microbiome of an obese woman.

Then, the scientists transplanted the gut microbiota before and after the low-calorie diet intervention into germ free lab mice in order to establish a so-called gnotobiotic mouse model.

Co-author of the research paper, Reiner Jumpertz-von Schwartzenber, explained that “In this way, we were able to determine that the sole effects of the diet shaped gut microbiome on metabolism and the immune system.”

They found that glucose metabolism improved and that fat deposition decreased as well after transplanting the microbiota.
