1000 calories is pretty much too few for anyone. Sparkpeople does not recommend that any female eat less than 1200 calories to ensure that they are getting the basic nutrition they need to support metabolic function. If you add exercise to the mix, you need even more to support that activity.
For men, that number jumps to 1500.
At 1,000 calories, you'll lose weight short term, but you're risking slowing your metabolism and sabotaging your long term weight loss efforts, and you're at high risk of rebound weight gain when you return to normal eating habits.
Restrictive very low calorie diets (under 1200 calories) should not be undertaken without the recommendation and guidance of a medical professional who can monitor your vitals and run blood tests to ensure that you're not damaging your body.
I generally eat between 1500-1800 calories most days.
