Recommended Answer:
Your current weight is pretty healthy. If you would like to lose weight, however want to make sure that you do not go the wrong way, then use a BMI calculator (like the one below) to ensure that you do not jeopardize you overal health/

Good luck

• You need to lose, by my well thought out and CORRECT calculations, 140 pounds
• Your BMI at 5''7 and 140 pounds is 21.9 which puts you in the normal weight rage. As long as you eat right, exercise and feel healthy overall then there is no need to loose weight. you could however safely loose 15 pounds and still be in a healthy weight range :)
  
  Underweight = <18.5
  Normal weight = 18.5–24.9
  Overweight = 25–29.9
  Obesity = BMI of 30 or greater
