Sorry I missed the bit in your first post but it adding up to 1000 calories.
1000 calories would be on the drastic side if you were trying to lose weight while being sedentary. IMO to stay healthy she needs to be looking at at least 1500 (possibly as high as 1800 depending on how much exercise she does on any given day) and adding more protein and stuff like beans and pulses.
No carbs and too little protein is going to mean no energy - you need fuel in the tank.
For perspective, today I have burnt off 900 calories in just over an hour on the bike.
