Dietary Treatment Most Effective for Losing Weight after Pregnancy

30.10.2012
While nursing and exercise help, sustainable weight loss after pregnancy requires lifestyle changes. A clinical trial conducted by Sahlgrenska Academy found that women who underwent dietary treatment averaged 10 percent weight loss.

Most women gain weight during pregnancy – typically only a few pounds, but pronounced and permanent approximately one-fifth of the time.

Given that a high body mass index increases the risk of complications and disease during and after pregnancy, the trend towards greater weight gain poses a serious public health issue. Women who are significantly overweight even before pregnancy are particularly vulnerable.

A 12-week study of 68 overweight or obese lactating women by researchers at Sahlgrenska Academy, University of Gothenburg, evaluated a dietary treatment method that produced an average of 10 percent weight loss.

The weight loss remained at one-year follow-up.

“The treatment involved providing the subjects with individual advice and support,” says Fredrik Bertz, the Sahlgrenska researcher who led the study. “The goal was for them to gradually reduce their consumption of sweets, snacks and soft drinks, choose low-sugar, low-fat food, fill half their plates with vegetables, cut back on the size of their servings, and weigh themselves on a regular basis.

“The results were unexpectedly encouraging. Not only did the women lose considerable weight, but they did not regain half of it during the first year as is normally the case when people go off a diet. The use of sophisticated methods also permitted us to confirm the effect of the treatment on calorie intake, metabolic rate and body composition (ratio of muscle to fat).”

Apart from ensuring the best possible nutrition for a baby, nursing helps a woman lose weight. In Mr. Bertz’s view, however, breastfeeding is not enough to produce the substantial reductions that overweight and obese women need.

“Little knowledge was previously available,” he says, “about the best way of treating obesity after pregnancy – diet, exercise or a combination of the two – to ensure permanent weight loss.

“This study has generated scientific data for developing new policies and making wise clinical choices. Our hope is that the results will help women achieve permanent weight loss after pregnancy.”

Surprisingly, the subjects who exercised in addition to receiving dietary treatment did not lose more weight.

“The reason may be is that all of the participants in the study were already relatively active,” Mr. Bertz says, “so that they were not in a position to significantly increase their metabolic rate. Previous research has found that exercise alone falls short as a strategy for losing weight.”

The article, entitled “Diet and Exercise Weight-loss Trial in Lactating Overweight and Obese Women,” appeared in the October 2012 issue of the American Journal of Clinical Nutrition.

FACTS ABOUT THE STUDY:

The study consisted of two phases: 12-week treatment, followed by nine months during which the subjects were on their own. Each subject was randomly assigned to one of four groups.

One group received individual dietary counseling based on Swedish nutritional recommendations, as well as instructions to weigh themselves three times a week in order to adjust their calorie intake. The target was weight loss of 1.1 pounds per week. Another group received individual exercise counseling and a pulsometer in order to adjust the intensity of milder exercise sessions. A third group received both dietary and exercise counseling, while the fourth (control) group did not receive any counseling at all.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
