Food gives us energy but not all food is equally beneficial for our bodies. When we are unwell, our bodies aren't functioning as they should, and we tend to pay close attention to what we consume. Once we feel well again, we may fall back into the habit of eating whatever is convenient and at whatever time is convenient. Sometimes, it is better to allow some time without food, giving our bodies time to use up the sugar and fats already present. Eating during a narrow interval every day is called intermittent fasting.
