Outcome Measures

Primary Outcomes (1)

  • maternal body fat gain

    Changes in total body fat as measured by air displacement between 20 to 34 weeks gestation

    20-34 weeks gestation

Secondary Outcomes (1)

  • Insulin Resistance

    20-34 weeks gestation

Study Arms (2)

Low Glycemic Load Diet

EXPERIMENTAL

Counseled to consume a diet with a low or higher intake of carbohydrate sources that cause rapid or significant intakes in blood glucose. The average glycemic load of the diet should be less than 55 per 1000 calories or greater than 55 per 1000 calories.

Other: Low Glycemic Load diet

Low Fat Diet

EXPERIMENTAL

Pregnant women were counseled to consume a diet providing less that 25% of the energy as fat.

Other: Low Fat Diet

Interventions

Pregnant women were counseled to consume a diet with a glycemic load per 1000 kcal of less than 55.

Also known as: LGL Diet
Low Glycemic Load Diet

Pregnant women were counseled to consume diets providing less than 25% of the energy as fat.

Also known as: LF Diet
Low Fat Diet
