weight loss

Severely obese women should lose weight during pregnancy, while obese women who are pregnant should gain less weight than currently recommended, a Saint Louis University study finds.

Since a longer labor is one consideration for whether or not a pregnant woman will have a Caesarean section, the new finding also means that a physician may need to take a woman’s weight into account before deciding whether or not to recommend her for the procedure, the study authors caution.The study appears in the November issue of Obstetrics and Gynecology

Those who lost more than 5 percent were less likely to stay in the hospital longer than four days, whereas those who lost more than 10 percent of their excess weight before surgery were more than twice as likely to have lost 70 percent of excess weight one year afterward, compared with those who lost between none and 5 percent of their excess pounds before surgery.The authors speculate that physiologic improvements associated with weight loss decreased surgical complications, reducing the length of hospital stay.

According to the article, obese patients are at risk for numerous health problems, including diabetes, hypertension, hyperlipidemia (high cholesterol), sleep apnea, osteoarthritis and other illnesses. Hypertension, dyslipidemia, glucose intolerance (a hallmark of diabetes) and obesity together represent a disorder called the metabolic syndrome.

The authors conclude that prescribing calcium and vitamin D supplements should be considered as a component of weight loss programs aimed at people with insufficient calcium intake.Professor Tremblay and his team have been studying the relationship between calcium and obesity for the past six years.

But does it matter where the calories come from? It might, according to findings from a small study published in the December 2005 issue of the medical journal Diabetes Care. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University discovered that a diet's overall "glycemic load" may be an important determinant of weight loss, but only for some people.

The first phase of a caloric restriction study in human subjects at the Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University found evidence suggesting that calorie-restricted diets differing substantially in glycemic load can result in comparable long-term weight loss.

In findings published in the May issue of Obesity, the researchers report that 80 percent of EatRight participants maintain their weight loss during two years of follow up, and most do it primarily by sticking to a low calorie, low energy density diet.Our results show that individuals who successfully maintain body weight after completing EatRight consume fewer calories and have a lower energy density dietary pattern than those who do not maintain body weight,” said Jamy Ard, M

Published in the most recent issue of Archives of Internal Medicine, the world's first 12 week parallelled, randomised, controlled trial compared the relative effects on weight loss and cardiovascular risk of low GI and high-protein diets.Undertaken by Professor Jennie Brand-Miller and Joanna McMillan-Price from the University of Sydney Human Nutrition Unit, the findings show that there is no 'one diet fits all' solution, and although both high protein and low GI diets will help you to shed fat.

Scientists at Aberdeen’s Rowett Research Institute have shown that a high protein, low carbohydrate diet is most effective at reducing hunger and promoting weight loss, at least in the short term.

Men and women who lose weight by cutting calories also may be losing bone density, but weight loss through exercise does not seem to produce the same effect, according to a report in the December 11/25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

The number of obese and morbidly obese Americans is steadily increasing, according to background information in the article. It is estimated that more than 30 percent of the U

While weight and obesity have long concerned women in relation to body image and lifestyle issues, few are aware of the possible risks that fluctuating weight could have on their unborn child, write Dr Jennifer Walsh and Professor Deirdre Murphy.They point to two studies.

articipants undertook a 12-week supervised exercise program that was individually tailored to expend 500 calories per session. During this time their weight loss and behavioural outcomes were monitored.

tQueensland University of Technology appetite regulation and energy balance researcher Dr Neil King, from the Institute of Health and Biomedical Innovation (IHBI), said our bodies have strong mechanisms to defend attempts to lose weight but very weak mechanisms to prevent weight gain.Dr King's weight loss intervention studies demonstrate the "plateau effect", whereby weight loss from exercise and calorie restrictions stops at a certain point

Weight loss is recognized as one of the better ways to keep pre-diabetes from turning into full-blown diabetes, experts say.In their examination of nine studies that included a total of 5,168 participants, Susan L.

Knopman explains that he does not consider the weight loss finding to be useful for diagnosis of dementia, and he does not envision that physicians who discover weight loss in their female patients later in life would immediately send the patient for memory testing. He hopes, however, that dementia researchers can pinpoint the brain mechanisms influencing the weight loss in women who develop dementia in order to better understand how it develops

James Anderson, a weight loss researcher, led a nine-year study of patients who have lost 100 or more pounds. Such weight loss can be achieved by following an intensive behavioral program.

Participants in all groups were oriented and encouraged to follow an internet weight loss program, with the automated and human groups also having access to an electronic diary and message board. In addition, the human group received weekly email feedback from a counselor, while the automated group received computer automated feedback messages.

To address this problem, researchers at the University of Pennsylvania School of Medicine have evaluated major commercial diets and self-help weight loss programs, providing physicians and their overweight patients with the first comprehensive review of these resources. The article will appear in the January 3, 2005 issue of the Annals of Internal Medicine
