"Cell Metabolism" What are immune cells doing when you're not sick?

When we fast, that is, we may not eat for half a day or a full day, we start to use our stored fat, but not all body cells are able to burn fat

Ketone bodies are also the focus of many popular weight loss recipes that focus on reducing carbohydrates in food so the body starts to burn fat

We now believe that the immune system affects the production of ketone bodies in healthy people, and given the beneficial role of ketone bodies in a variety of common metabolic disorders, this knowledge can hopefully be applied to understanding how the immune system keeps our bodies in balance when we are sick, Annie Loft explained
