Have a diet ever made you feel dizzy?

I was in my dorm room and I am on a diet I got an amazon delivery. The driver called me and when I went down to open the door for him my head started spinning and I lost my sight all I saw was the color red. I balanced myself by putting my weight on the door the driver approached me and asked me “are you okay do you need help” and i told him i am completely fine and okay. I refused his help. But when i sit i stop feeling dizzy and i felt it when i was on my feet. I went to my room and i had a soup right away and i felt better. Is this normal with a rough diet?
