Intermittent fasting (IF) is very popular these days. Many people claim it helps lose weight, improve energy, or even increase focus. But like everything, it’s not perfect. Beginners can get confused about how it works, if its safe, or what benefits it really gives. Here is a casual look at pros and cons of intermittent fasting.
