This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how fasting affects your body's immune system and the healthy bacteria in your gut. This study will ask you to fast for 36 hours (drinking only water) while researchers collect blood samples and monitor your blood sugar levels. The goal is to learn whether short-term fasting has benefits for immune health.
Studies in animals and some humans suggest that fasting may help regulate the immune system and reduce inflammation, but scientists need more research in healthy people to understand exactly how this works and whether it could be a useful health strategy.

You will complete a 36-hour water-only fast while researchers monitor your health and collect samples. During the fasting period, you'll use a home blood glucose meter to check your blood sugar several times, and you'll collect stool samples for analysis of your gut bacteria. The study involves blood tests before and after the fasting period to measure how your immune system responds.
