Italian researchers have discovered that healthcare workers with obesity produced only about half the amount of antibodies in response to a second dose of the vaccination compared with healthy people. Do not get sloppy with your diet during the pandemic.
Previous research has suggested that obesity – which is defined as having a body mass index (BMI) over 30 – increases the risk of dying of Covid-19 by nearly 50%, as well as increasing the risk of ending up in hospital by 113%.
Some of this may be because people with obesity often have other underlying medical conditions, such as heart disease or type 2 diabetes, that increase their risk from the coronavirus, but excess body fat can also cause metabolic changes, such as insulin resistance and inflammation, which make it harder for the body to fight off infections.
This constant state of low-grade inflammation can also weaken certain immune responses, including those launched by the B and T cells that trigger a protective response following vaccination. Separate research has shown that the flu vaccine is only half as effective in people with obesity compared to those who are a healthy weight.
The new study, which has not yet been peer reviewed, provides the first direct evidence to suggest a similar problem might occur with Covid-19 vaccines.
In a separate study of Brazilian healthcare workers, Altmann and his colleagues showed that reinfection with Sars-CoV-2 was also more common among people with a high BMI, and that they tended to have lower antibody responses to the original infection.
We know the temptation is high to eat more junk food as a result of psychological stress, but try to pay attention to keep a healthy diet. Following your regular exercise routine might have become challenging, therefore there is more focus on diet to help your body coping any infections.
