What does shaking mean if you haven't eaten anything?

Yep low blood sugar. Are you dizzy or lightheaded too.

This sometimes happens to me as I don't have any regular hours or meals. You should eat a mountain of protein. If you are like me you will get extremely tired and have a headache for a few hours - then you are good

Low blood glucose concentration. Eat a banana.

Protein. Eat the biggest chicken or beef you can

Low blood sugar

That you need to eat

Glucose low
