Dietary Restraint and Gestational Weight Gain

Women who diet "habitually" prior to becoming pregnant tend to gain more weight during pregnancy and "regard themselves as less accountable for their weight while pregnant," according to researchers at the University of North Carolina.

More than 1,200 women were studied to determine whether a history of dieting and restrained eating prior to pregnancy was related to higher weight gains in pregnancy.

The researchers note that excessive gestational weight gain "is of concern because of its association with postpartum weight retention" and other "adverse pregnancy outcomes such as gestational diabetes mellitus, cesarean sections, large-for-gestational age, and breastfeeding duration."

"With the exception of underweight women, all other women with a history of dieting or restrained eating gained more weight during pregnancy and had higher adequacy of weight gain ratios," the researchers found.

They concluded: "Restrained eating behaviors were associated with weight gains above the Institute of Medicine's recommendations for normal, overweight, and obese women and weight gains below the recommendations for underweight women."

American Dietetic Association Issues New Position Statement on "Health Implications of Dietary Fiber"

Adequate intakes of dietary fiber help protect against cardiovascular disease, obesity, diabetes and gastrointestinal disorders. Usual intakes of dietary fiber in this country are only half of the recommended levels, so there is a need to promote high-fiber foods such as whole grains, legumes, vegetables and fruits to people of all ages. Not all dietary fibers are equally effective in their physiological effects, so it is best to obtain fiber from a wide range of sources. The American Dietetic Association encourages consumers to consume adequate amounts of fiber, particularly from food sources, according to a new ADA position statement published this month on the health implications of dietary fiber:

It is the position of The American Dietetic Association that the public should consume adequate amounts of dietary fiber from a variety of plant foods.
