New research announced Monday found that when human stem cells — the blank slate of the cell world — were exposed to a common virus they turned into fat cells. They didn’t just change, they stored fat, too.

While this may be a guilt-free explanation for putting on pounds, it doesn’t explain all or even most of America’s growing obesity problem. But it adds to other recent evidence that blames more than just super-sized appetites and underused muscles for expanding waistlines.

What is “moderate exercise”?

August 21st, 2007

UK Government guidelines recommend that we take 30 minutes of moderate exercise most days of the week. But what is “moderate exercise”?

How many times have you been to the gym and watched a person reading a book or magazine while on the upright bike? How many people do you see each day that are dressed for exercise but are just strolling around the village?

At fitness-etc we believe that one of the simplest ways to check the intensity of your workout is to use the Rate of Perceived Exertion (RPE) scale. Read more »

Researchers found the cancer was much less likely to develop in people who are insulin resistant - a pre-diabetes condition linked to obesity.

But they were more likely to develop an aggressive form of the disease likely to spread to other parts of the body.

The study involving 784 men, by Sweden’s Umea University, is published in the International Journal of Cancer. Click here for full article

Mixed Messages: Let Your Kids Eat Fat

August 16th, 2007

Parents should not restrict their children to low-fat diets despite concerns about obesity, experts have said.

A new study, published in the Nutrition Journal, says fat can be included as part of a healthy and balanced diet and has an important role in helping youngsters grow.

Today’s research found that children burn more body fat than adults for each calorie used up.

Pot belly linked to heart disease

August 15th, 2007

Even a small pot belly can increase the risk of heart disease, scientists warn.

Research from the University of Texas found large waist measurements, relative to hip size, were linked to early signs of heart disease.

This confirms other research that waist size, rather than overall body weight, is a key indicator of heart disease.

The study of 2,744 people suggests that a waist size of 32ins (81cm) for a woman and 37ins (94cm) for a man represents a “significant” raised risk. Click here for full article

August 14th, 2007

Even low levels of weekly exercise could help reduce blood pressure and improve fitness, scientists say.

Experts say walking for half an hour, five days a week, is the minimum required to achieve health benefits.

But a Journal of Epidemiology and Community Health report from Northern Ireland found walking on just three days a week gave similar benefits.

The finding could encourage those with sedentary lifestyles to take up exercise gradually, the authors say.

This could be helpful as few people currently meet the minimum recommendations for exercise, with many saying they do not have enough time. Click here for full article
