Okay to Skip Meals?

Q: I'm trying to learn to listen to my body and eat only when I am hungry, and sometimes I just don't really want anything to eat. Is it okay to skip meals or to eat fewer than the recommended calories?

A: 
You should NOT skip meals. There are so many adverse effects to skipping meals. Not only does it slow right your metabolism but it can lead to overeating, because when you do eat you're overly hungry.
As for cutting your calories below your calorie allowance, this is tricky. The first golden rule is never to let your daily calorie allowance fall below 1,200 if you are a woman and 1,500 if you are a man.

Falling below these daily allowances can do real damage to your metabolism and result in excessive loss of lean muscle tissue. When you dramatically reduce your calories on a consistent basis, it can slow your metabolism or trigger a plateau. Consistent exercise — plus the occasional high-calorie day — will help ward off a plateau.

Now, provided you are not going below 1,200, you CAN drop your daily calories below your allotted allowance, but make sure that you are exercising and taking the occasional high-calorie day to help you avoid a plateau.
