Answer To Your Fitness Questions" />Physical Activity Reduces The Risk For Obesity
September 11, 2008
The most recent study on obesity gives those people suffering from this “disease” a renewed chance of improving their condition. Research has always showed the importance of physical activity day-to-day and within this study it makes no exception.
More specifically, the new study shows that physical activity actually may reduce the risk of obesity in people with a genetic mutation that predisposes them to high body mass index. Background study information points to a particular gene, known as the obesity and fat mass gene, to be the link between people and high body mass index. These gene mutations happen in about 30 percent of European populations and are directly correlated with a 1.75 kilogram (3.9 lb) increase in body weight.
Within the study, researchers at the University of Maryland studied DNA samples from roughly 704 healthy adults with an average age of 43.6. Fifty percent of men and sixty percent of women were deemed overweight, while 10 percent of men and 20 percent of women were considered obese. Each participant was fitted with “accelerometers” measuring their physical movements over time.
Research found that those participants with the genetic variant were no more likely to be overweight than those without as long as they exercised three to four hours every day (exercise includes moderate activities like brisk walking, gardening, and houscleaning).
”Our results strongly suggest that the increased risk of obesity due to genetic susceptibility can be blunted through physical activity. Some of the genes shown to cause obesity in our modern environment may not have had this effect a few centuries ago when most people’s lives were similar to that of present-day farmers.” Dr. Soren Snitker, lead author of research University of Maryland, said. “These findings truely emphasize the important role of physical activity in public health efforts to combat obesity, particularly in genetically susceptible people.

I think it is of the utmost importance for people to understand that weight gain is something that can be overcome even if everyone in your family has yet to defeat it.
