Omega-3 Fatty Acids Increase Satiety During Weight Loss
Obese subjects who consume omega-3 fatty acid supplements while following a weight loss program feel fuller longer, according to the results of a new study.
The study involved 232 overweight and obese volunteers who were randomly assigned to an energy restricted balanced diet and supplemented with either low dose (260 mg per day) or high dose (1,300 mg per day) omega-3 fatty acids for eight weeks. During the last two weeks of the study, the study authors measured the subjects' appetite.
The subjects who consumed the balanced diet diet together with the high dose of omega-3s experienced less hunger immediately after the test meals, as well as two hours later, compared to subjects consuming the low-dose omega-3s.
Weight Loss: Americans Continue to Struggle with Losing Weight
The latest U.S. health and nutrition survey shows that obesity continues to rise in American adults and children and that a large percentage of the country is dangerously overweight. Results of the survey were published in two studies that appeared in a recent issue of the Journal of the American Medical Association. The survey shows that 30 percent of adults in America (59 million people) were obese in the year 2000. This is a seven percent increase from the 23 percent considered obese in 1994. The same trend towards obesity was seen in children in the years 1900 and 2000, with 15 percent (9 million) children considered overweight or obese three times the rate of obesity two decades earlier. In addition, ten percent of preschool children are considered overweight, whereas seven percent of children in the same age group were considered overweight in the 1990s.
The study authors used data from the National Health and Nutrition Examination Survey (NHANES). These results are particularly alarming due to the association between obesity and diabetes, cardiovascular disease, stroke, high blood pressure and certain types of cancer. The problem keeps getting worse, said Tommy Thompson, secretary of the U.S. Department of Health and Human Services. We’ve seen virtually a doubling in the number of obese persons over the past two decades and this has profound health implications.
Because of the connection between high-glycemic foods and weight gain, keeping these toxic foods out of the diet are essential to weight loss.
Higher Vitamin D Levels Associated with Less Weight Gain
A study published in June 2012 reports that higher vitamin D levels may minimize weight gain in women. Data from the National Health and Nutrition Examination Surveys (NHANES) 2001-2006 indicates that approximately 25 percent of the population is at risk of vitamin D insufficiency and 8 percent is at risk for vitamin D deficiency. However, other research published in the Journal of the National Medical Association in 2011 shows that 65 percent of an urban population was vitamin D deficient.
Researchers set out to determine the role vitamin D plays in weight management, as vitamin D levels are lower in obese individuals. The investigators evaluated 4,659 women age 65 and older.
At the beginning of the study, researchers found that the women with higher vitamin D levels had lower weight. The researchers also showed that among the women that gained five percent of body weight or greater during the follow-up period, those with higher vitamin D levels showed less weight gain between visits.
Statins Increase Risk of Diabetes Mellitus in Men
A study published in May 2015 reports that statin medications increase the risk of diabetes. Statins are among the most prescribed medications. The researchers concluded, "Statin treatment increased the risk of type 2 diabetes by 46%, attributable to decreases in insulin sensitivity and insulin secretion."
