977 sounds wayyy too little. I lost weight with my fitdayBMR minus 500, but found that minus 750 I did better. Remember that the regular BMR doesn't take into account ANY exercise, its the no of calories you need to stay awake and for your body to function.
I usually aim for Fitday BMR plus exercise (remember to add the calories you burned for exercise) minus food eaten = 500-750, I usually try to eat no more than 1800 calories, but sometimes go as low as 1600. Can't answer the bits about the starvation mode etc...I know there are people on here who will come back with more scientific answers than this, but hope this much helps somewhat.
