dietary focus

Hey there!  I'm 9 weeks out  have lost about 35 lbs.  my question is what should my focus be.  the metabolic specialist says my caloric expendature is 2200 cal at rest so do i i try to lose based on calories or just make sure i consume my protein grams.  my daily caloric intake is 700 to 1100 a day. is this putting me in starvation mode? Is  this why my weight loss has been low.  i also have only been working out 30 min 2 times a week on average.  I'm getting nervous about failure. any advice will be greatly appreciated
