Glycogen, otherwise known as sugar, within the muscles and liver decrease in the night as you sleep. Conventional wisdom suggests that exercising on an empty stomach would promote fat burning and weight loss.
A study from the University of Padua in Italy found the opposite to be true: physical activity after a light meal WORKED BEST best for losing body fat. Researchers studied fat metabolism in 8 males who ran on a treadmill at 65% of their maximum heart rate for 36 minutes on two different occasions - either without eating and after a light breakfast.
Study: 42% Will Be Obese by 2030 -- News Review From Harvard Medical School
2012-05-15 - General Health
A new study says 42% of U.S. adults will be obese by 2030. Just over
one-third are obese now. The new study says the rate of increase in
obesity is slowing down. But even the smaller increases will add up.
Also by 2030, about 11% of Americans will be severely obese, the study
predicts. That's at least 100 pounds overweight. People who are severely
obese have the greatest increased risk of heart disease, diabetes and
other illnesses. The new research was presented at a health conference.
The Associated Press wrote about it May 7.
Exercise Prevents Cancer
Exercise is connected with a lower occurrence of colon cancer in
men and women, and of breast cancer in women. In the November 2003 issue of Medicine
& Science in Sports & Exercise, it has been reported that moderate to
vigorous physical activity has a greater protective effect against cancer than lower
intensity physical activity. It seems that about 30–60 minutes of moderate to
vigorous exercise per day is needed for risk reduction. In addition, physically active women have
a 20%–40% reduction in relative risk for breast cancer compared with their
Being pregnant is no time to ditch the gym. Moms-to-be who frequently worked out doing moderately hard workouts ( a 5 to 7 on a scale of 1 to 10) in the first trimester had a lower risk of preterm birth, reports a new study. Their bodies may replenish more nutrients to their placentas after they exercise, says study author Anne Marie Jukic, Ph.D., a researcher at the National Institute of Environmental Health Sciences. Talk to your doctor about exercising while you're expecting she says: If you have certain risk factors or didn't exercise regularly beforehand, you may need to take special precautions.
September is National Childhood Obesity Awareness Month
While data shows that obesity
numbers continue to rise, perhaps the most frightening numbers related
to obesity are those among the children in the United States. More than
23 million children over the age of 2 are either obese or overweight.
This month, organizations across the country are joining forces to
increase awareness about this alarming trend of childhood obesity. The
fitness industry can play an important and active role in educating the
If your mom is overweight, your own figure isn't doomed. A study in PLoS Medicine found that doing any amount of exercise is linked to a 40% reduction in the genetic risk of being overweight - and people with the most obesity-related DNA sequences saw the biggest benefits from exercise. No excuses now.
Best Fight Cancer, New Guidelines Urge Exercise
People undergoing cancertreatment traditionally have been told to
rest as much as possible and avoid exertion, to save all their strength to
battle the dreaded disease.
But a growing number of physicians
and researchers now say that people who remain physically active as best they
can during treatment are more likely to beat cancer.
The positive evidence for exercise during and after cancer treatment has
piled so high that an American College of Sports Medicine panel is revising the
group's national guidelines regarding exercise recommended for cancer
