Well, I did 1200-1400 calories for months to get to my goal with no ill effects, but I'm female, 5'2", and 43 years old. It's hard to say if it's healthy and do-able for you not knowing your stats.
However, one of our weight loss stars, Michael, sticks to 1500 calories a day, and he's had great success. Also, they say a 1-2 pound loss per week is safe and sustainable, and 1000 calories deficient will get you that. So my initial impression is to say give it a try, but be prepared to tweak it if you find it's not working for you.
And now that you don't have to be perfect, you can be good.
