intervention helps high risk men"
There have been increasing initiatives to
help educate the public about the vital significance of healthy
lifestyles for good overall health. The Centers for Disease
Control and Prevention writes that the significance of good
nutrition and physical activity to reduce rates of disease and
death from chronic diseases has been well established. It has
been found that poor diet and physical inactivity cause 310,000
to 580,000 deaths per year and are primary contributors to disabilities
which result from diabetes, osteoporosis obesity and stroke.
A new study has showed that intensive lifestyle intervention
improved several diabetic and cardiovascular risk factors in
men who were at high-risk. Researchers reported visceral adiposity
decreased by 26 pecent and cardiorespiratory fitness improved
by 20 percent in viscerally obese men, after one year of a diet
and physical activity intervention. Furthermore, glucose tolerance
improved, independent of changes in adiposity. In this study
the lifestyle intervention included diet modification along
with physical activity counseling every two weeks for the first
four months, and then monthly.
The nutritional counseling was personally adapted in order
to elicit a 500-kcal daily energy de?cit, with less than 30
percent of kilocalories coming from lipids, which were preferably
unsaturated. Oral glucose tolerance tests and oral lipid tolerance
tests were performed at baseline and again at pne year. The
results showed that fasting free fatty acids (FFAs) and concentrations
after the oral glucose load were significantly lower at one
year, in spite of decreased plasma insulin concentration. The
researchers wrote, "Thus, lower concentrations of plasma
insulin were better able to modulate plasma FFA concentrations,
suggesting an improvement in insulin sensitivity of lipolysis."
