It's a sign of the times that everyone is becoming more conscious of not only their health but also their immune health. We think it's important for you to understand just how your diet impacts your immune system and how a Keto diet can provide a lot of immune benefits!

There is lots of different research that has shown that your diet does in fact impact your immune function, for instance:

Insulin resistance caused from eating large amounts of carbs can both increase inflammation and alter immune function.

Adding Probiotics and fermented foods to your diet can not only lower your risk of infection but also speed up recovery by decreasing the severity of your illness

Obesity and excess visceral (belly fat) can lower immune function and increase the risk of an infection

What Are The Keto Benefits For Immune Health?

Research has found that eating a low-carb, moderate protein Keto diet may provide your immune system with a range to benefits besides having more energy to fight off infections like the flu.

In a 2019 flu-study at Yale, Researchers fed mice infected with the influenza virus a high-fat, low-carbohydrate diet, which resulted in a higher survival rate than compared to those on a normal high-carbohydrate diet.

Aikiko Iwasaki and his colleagues found that mice on a Keto diet were not only less affected by the flu virus, but that a Keto diet produced more T cells, which are mucus-producing and create a protective layer within the lungs, and allow the virus to be trapped and expelled before entering the body and worsening. It also gave the mice increased energy levels to aid them in fighting off the infection.

Eating a Keto Diet, such as the Ultra Lite Program also has positive effects on your microbiome, it in turn lowers the inflammation within your body and can even help to reverse insulin resistance–all of which is good news for the flu and other infections.
