M.S

The optimal diet is one that’s as good for the brain, bones, heart, and

intestines as it is for the waistline—and it must supply all nutritional needs.

To determine

whether current weight is in the optimal range, check the body mass index

(BMI) in table12.1 (). In women who are overweight (BMI of 25 to 29.9) or obese (BMI above 29.9), weight reduction can decrease the risk of

gestational diabetes, high blood pressure, and preeclampsia (a condition that

includes high blood pressure, fluid retention, and protein loss in the urine)

underweight:

• Overweight. At least 10 percent above healthy body weight (for most

people, about 10 to 30 pounds above healthy body weight).

• Obese. At least 20 percent above healthy body weight (for most people, 30

pounds or more above healthy body weight).

• Underweight. At least 15 to 20 percent below healthy body weight (for most

people, 20 to 30 pounds under healthy body weight).
