That's what I do! I'm only 5'3 and at a 21 BMI and sedentary that's actually a perfectly safe number if you watch macros and take vitamins. You only need more if you're taller and/or active. I did 1000 while taking really good vitamins over 6 months straight and dropped 45 pounds, I went from from high overweight to middle of normal. I lose about 2  pounds a week on 1000, which is a reasonable number. Now that I'm on maintenance I actually just occasionally do it for a couple days here and there if I've gained anything (I'm never getting that fat again), but I suffered no ill effects at all over that half year. Protein is super important on it though, so it's pretty much chicken breast and tuna all around, with some salad or soup or what not. A little oatmeal or granola & yogurt for breakfast. It's not as horrible as it sounds at all.
