This would be the worst thing to do, Lisa. Your body interprets a caloric restriction as a sign to decrease metabolism further. The best things to do would be

• 
  1. Eat more often - have 6 smaller meals instead of 3 larger ones a day. Eating actually boosts your metabolism.
  
  2. Lift some weights. Build some lean muscle mass - this will boost metabolism and burn more calories all day long (even while you're sleeping)

Don't cut back on what you're eating though; you'll just make matters worse.
