Been eating 1300 - 800 Calories A Week, Is This Super Unhealthy?

I've been counting calories like a motherfu**er since i started my diet two weeks back, im eating pretty healthy, no mars bars.. no chocolate.. avoiding sugars as much as humanly possible

I am super determined to loose weight, but i fear i may be over doing it as i have lost 1.5 KG this week
