Diet, Weight Loss Ease Menopause Symptoms: Study

HealthDay – 1 hr 2 mins ago WEDNESDAY, July 11 (HealthDay News) -- Menopausal women who lose weight eating a low-fat diet rich in fruits and vegetables could reduce or eliminate their hot flashes and night sweats, a large new study suggests.

One reason the researchers looked at weight loss as a way of dealing with menopausal symptoms was because of long-standing research linking hormone-replacement therapy to heart disease and breast cancer.

"We wanted to see if this could be an alternative to hormone therapy," said lead researcher Candyce Kroenke, a research scientist at Kaiser Permanente's Northern California Division of Research in Oakland.

"Indeed, women who lost weight in the context of this healthier diet -- decreasing fat, increasing whole grains, fruits and vegetables -- were significantly more likely to reduce or eliminate symptoms," she added.

Reduced hot flashes and night sweats, the key menopausal symptoms, were seen in both overweight and normal-weight women who lost weight, Kroenke noted.

And the reason for that is fairly simple, she said: Fat tends to retain heat and losing weight helps the body dissipate heat more easily.

The report, which was published July 11 in the online edition of Menopause, involved data on more than 17,000 women who took part in the Women's Health Initiative study.

The women with menopausal symptoms who were on a low-fat diet rich in whole grains, fruits and vegetables, who were not taking hormone-replacement therapy and who lost at least 10 pounds in a year were more likely to see night sweats and hot flashes reduced or disappear after a year than did women who maintained their weight (the "control" group), the researchers found.

Dr. Jennifer Wu, an obstetrician/gynecologist at Lenox Hill Hospital in New York City, commented that "this definitely goes along with the idea that good diet and exercise and losing weight contribute to general health."

And, she added, "It's a quick and easy fix for hot flashes and night sweats."

Wu noted that doctors are still reluctant to offer hormone-replacement therapy even though it works. "This is a low-risk fix," she said.

"I think it will work for some patients, and patients may only get a partial relief of their symptoms, but any help is good," Wu pointed out.

"Diet and weight loss is a healthy habit that will hopefully help menopausal symptoms. There is very little downside to doing it," she added.

Another expert agreed.

"Adopting a healthy diet is always a good idea," said Samantha Heller, a nutritionist, exercise physiologist and clinical nutrition coordinator at the Center for Cancer Care at Griffin Hospital in Derby, Conn.

"Healthy foods, including vegetables, soy, whole grains, legumes, nuts and fruits, decrease the risk of many chronic diseases and can improve health and well-being considerably. In this case, along with weight loss of 10 pounds or 10 percent of body weight, women who made healthy dietary changes tended to have decreased symptoms of hot flashes and night sweats," Heller noted.

"This study also highlights the positive effect of ongoing nutrition education by registered dietitians," she added. "Women in the intervention group, who were counseled by registered dietitians, were three times more likely to lose weight than women in the control group. A big factor in unsuccessful weight loss attempts is people not knowing how or where to begin. Nutrition counseling takes the guesswork out of creating a healthy lifestyle and helps motivate and empower people to stay on track."

The research was published just days after a coalition of leading medical groups concluded in a joint statement that hormone-replacement therapy can be useful and safe for many women suffering from the symptoms of menopause.

The coalition includes 15 medical groups, including the North American Menopause Society, the American Society for Reproductive Medicine, the Endocrine Society and the American Academy of Family Physicians.

Weight in pregnancy best controlled by diet, study suggests

ScienceDaily (May 18, 2012) — Pregnant women, including those who are obese or overweight, should be encouraged to minimise weight gain through diet, according to major new research from Queen Mary, University of London.

Piling on excess weight during pregnancy increases the risk of complications for pregnant women but doctors have been cautious in advising women on ways to manage weight for fear of any adverse effect on mother or baby.

However, the new study published in the BMJ shows that following a healthy diet, overseen by health professionals, stems excess weight gain in pregnancy and reduces the risk of pregnancy complications such as pre-eclampsia, diabetes, high blood pressure and early delivery.

Half the UK population are either overweight or obese and the rates are rising. Around a third of women gain more than the recommended amount during pregnancy.

Previous research has linked obesity during pregnancy with an increase in a variety of risks including high blood pressure, diabetes, miscarriage, birth defects, blood clots, pre-eclampsia, and even maternal and infant deaths.

The new research, which brings together the results of 44 separate studies, is the largest of its kind and includes data on more than 7,000 women. It was commissioned and funded by the NIHR's Health Technology Assessment programme.

The researchers investigated the effect of diet, exercise, or a combination of the two. They looked at how much weight women gained throughout pregnancy and whether mother or child suffered from any complications.

Although all three methods reduced the mother's weight gain, diet had the greatest effect with an average reduction of nearly four kilograms. Exercise only resulted in an average reduction in weight gain of just 0.7kg. A combination of diet and exercise only produced and average reduction of one kilogram.

Women who followed a calorie controlled diet were 33 per cent less likely to develop pre-eclampsia, one of the most dangerous pregnancy complications that presents with raised blood pressure and protein in the urine. Their risk of gestational diabetes was 60 per cent lower, their risk of gestational high blood pressure was 70 per cent lower and their risk of early delivery was 32 per cent lower. However, the researchers acknowledge that these findings need to be confirmed by further large studies.

Crucially, babies' birth weights were not affected by dieting.

The research was led by Dr Shakila Thangaratinam, a Clinical Senior Lecturer and Consultant Obstetrician at Barts and The London Medical School, part of Queen Mary, University of London with researchers in UK and Europe. She said: "We are seeing more and more women who gain excess weight when they are pregnant and we know these women and their babies are at increased risk of complications."

"Weight control is difficult but this study shows that by carefully advising women on weight management methods, especially diet, we can reduce weight gain during pregnancy. It also shows that following a controlled diet has the potential to reduce the risk of a number of pregnancy complications.

"Women may be concerned that dieting during pregnancy could have a negative impact on their babies. This research is reassuring because it showed that dieting is safe and that the baby's weight isn't affected."

Dietary advice was based on limiting overall calorie intake; balancing protein, carbohydrate and fat; and eating foods such as whole grains, fruits, vegetables and pulses.

Dr Thangaratinam added: "What we don't know is why diet should be so much better than exercise in controlling weight gain. It could be that it is simpler and easier for women to stick to. It may also be that eating a high-fibre diet has other positive health effects for a pregnant woman."

Combining data on the thousands of women who participated in these trials will also allow researchers to further examine the effects of diet and exercise across women of various ages, body mass index, ethnicity, socioeconomic status and medical conditions.

The Women's Health Research Unit at Queen Mary, University of London has recently established an international collaboration on Weight Management in Pregnancy (i-WIP) to answer these questions.
