Why do you start trembling/shaking if you haven’t eaten in a while?

When you start trembling due to hunger, this is likely caused by hypoglycemia, which is low blood sugar. When your brain detects low blood sugar, it activates your stress response, which releases hormones such as epinephrine and norepinephrine, which will raise your blood sugar levels but also cause you to become shaky. The condition is called physiological tremor.
