Belly Fat Study Finds a Key to Losing That Spare Tire
SHOP NOW
A Harvard School of Public Health (HSPH) study
looked at different types of exercise to find which is best at reducing
belly fat. The study is published in the December issue of the journal
Obesity.
I don’t usually talk about weight loss as an overall health goal. As a
former disordered eater, I know that focusing on weight loss can be an
unhealthy way to try to get healthy. Health isn’t about shedding pounds.
It’s about eating healthy, whole foods and staying active. It’s about a
lifestyle, not what you see when you step on the scale.
So, what am I doing talking about belly fat? It turns out that fat
stored around the midsection is not just annoying. Reducing belly fat —
not losing weight — might protect our overall health.
After a bit of digging I learned that body shape is closely correlated with our overall health.
Folks who store fat in our midsections as opposed to our hips and legs
are at a higher risk for diabetes, heart disease, high blood pressure,
and stroke. In fact the HSPH study’s lead author Rania Mekary, a
researcher in HSPH’s Department of Nutrition says, “body weight alone is
insufficient for the study of healthy aging. Measuring waist
circumference is a better indicator of healthy body composition among
older adults.”
Mekary is talking about something called the Waist to Hip Ratio.
You measure your waist at the narrowest point and divide it by your hip
measurement at the widest spot. So, if your waist is 28 inches and your
hips are 32 inches, your Waist to Hip Ratio would be 0.875. A healthy
Waist to Hip Ratio for women is 0.8 or lower. For men, 1.0 or lower is
considered healthy.
The Harvard belly fat study looked at 12 years of physical activity
data for 10,500 healthy U.S. men aged 40 and over. Some of the men
focused more on different types of cardiovascular exercise while others
did more weight training. It found that
the men who spent 20 extra minutes a day on weight training lost two to four times as much belly fat as men doing cardio.
Senior study author Frank Hu summed up the results: “This study
underscores the importance of weight training in reducing abdominal
obesity, especially among the elderly. To maintain a healthy weight and
waistline, it is critical to incorporate weight training with aerobic
exercise.”
This study only looked at men over age 40, and of course more
research is needed to see if women over 40 and both men and women in
other age groups get similar results. The good news is that there’s
already evidence that weight training is good for women,
too. Getting stronger and building endurance is good for us at any age
and any gender. If you’re concerned that weight training could cause you
problems because of existing health conditions, your doctor or a
personal trainer can give you recommendations about how to weight train
safely.
This research doesn’t mean that we should ditch our cardio routines.
Cardiovascular exercise — like walking, running, and swimming — comes with its own set of health benefits.
What the study shows is that we need to balance our cardio with weight
training. That could mean lifting free weights or using weight machines.
It could mean using resistance training, like pushups, squats, and
lunges. Just as with diet, a healthy exercise routine is about balance and variety.
