Just out of curiousity, I caculated your
BMI (from
http://www.globalrph.com/diet_calc.cgi).
Here's what the
Dieting Calculator says:
Your BMI (body mass index) is: 18.8
Further analysis of your BMI: Underweight
At your height and weight any
dieting would not be helpful at this point (unless you are shooting just to eat healthier). You'll get skinnier, but not necessarily in a complementary way. You may keep your problem areas (flab), but your face could start to look skelatal and old--and you will probably lose some breast size.
Please trust me, the "starving boy" look isn't pretty on anyone. I've been there, and so has my little sister (who ironically is the same height as you).
My sis actually weighs 130 now (still low on the
BMI--but she's healthy) and she looks great. She has virtually no
body fat, but is she is healthy and has
energy for the first time I've ever known her.
Her husband (an ex-anorexic who professional weight trains) taught her how to eat and exercise. Two huge things she changed in her
diet was increasing her
calories by eating more grains and veggies (and evil carbs

). And she also began eating breakfast every morning.
This increased her metabolism--making her more efficient at burning
calories and giving her the
energy to exercise and burn away the troublesome "flab." She rotates her
exercises (biking,
pilates, weight lifting) so she doesn't injure herself or get "too thin." It also keeps her from getting bored with it. This works really well for her. She not only looks fantastic now, but she's happy and energetic.
