10 Ways to Lose Weight
Losing weight is the easy part. Keeping it off is
the real killer. Rena Wing knows. For more than 10 years she has tried
to ferret out how some people manage to lose weight and avoid regaining
it. Here's what she's learned from the 6,000 successful weight losers
in her National Weight Control Registry.
Q:
What is the National Weight Control Registry?
A:
Researchers know little about people in the real world who have lost
weight and managed to keep it off. We wanted to identify a large group
of them, so that we could describe the strategies they used.
We
have 6,000 successful weight loss maintainers whom we've recruited
through newspaper and magazine articles. Most are white, middle-aged
women. We ask them to fill out a series of questionnaires, then we
contact them once a year to ask about their weight and weight-related
behaviors.
Q:
What led them to lose weight?
A:
Almost all had tried before, but few had succeeded at keeping the
weight off. In nearly every case, something triggered them to try
again, usually a medical condition that threatened their health, or
they reached their all-time high, or they saw themselves in a mirror or
picture.
Q:
How much have they lost?
A: To be eligible for the registry, participants had to have lost at least 30 pounds and kept it off for at least a year. But that's just the minimum. Our average participants have lost about 70 pounds and kept it off for six years. One in eight has kept the weight off for more than 10 years.
Q:
How did they lose it?
A:
Usually through some combination of diet and exercise. Only about 10
percent used diet alone, and just I percent relied on exercise alone.
Half got help with their weight loss efforts, such as joining Weight
Watchers or working with a nutritionist. That's what the women
preferred. The men preferred doing it on their own.
Q:
What kinds of diets did they use?
A:
There was no one successful type. Many restricted specific foods like
desserts. Some controlled the amount of food they ate. Others counted
calories or fat grams. A few used liquid formulas or exchange system
diets.
Q:
How do they keep the weight off?
A:
They do seven things primarily. They eat a low-calorie diet, they eat a
consistent diet from day to day, they eat breakfast, they're very
physically active, they weigh themselves frequently, they watch only a
limited amount of television, and they don't let a small weight gain
become any bigger.
Q:
What kind of low-calorie diet?
A:
It's relatively low in fat and high in carbohydrates. Very few of them
eat a low-carb diet. And they eat four to five times a day.
Q:
Why does eating breakfast matter?
A:
It probably helps reduce hunger later in the day. Most registry
participants eat breakfast every morning.
Q:
What's the advantage of eating the same way every day?
A: We thought participants would give themselves a
break and eat differently on weekends or holidays, but they don't. And
they eat a smaller variety of foods than, say, other people who have
recently lost weight. Reducing the number of foods they eat may
simplify their diet and make it more boring, which helps them eat fewer
calories.
Q:
How physically active are they?
A:
More than most other people. They work their way gradually up to about
60 minutes a day of moderate-intensity physical activity. Walking is
their number-one exercise.
To
find out how much they walked, we asked some of the participants to
wear pedometers. It turns out they took 11,000 to 12,000 steps a day.
That's equivalent to 5 1/2 to 6 miles. And they watch only about 10
hours of television a week--a third of what the typical American
watches.
Q:
What other exercises do they do?
A:
About half of the participants combine walking with something that's
more planned, like aerobic class, resistancetraining, biking, or
swimming.
Q:
Why do registry participants weigh themselves regularly?
A:
Three-quarters weigh themselves at least once a day or once a week.
It's part of an ongoing vigilance that lets them keep conscious control
over their weight.
Although
about two-thirds keep their weight stable or even lose more, the other
third do gain five or more pounds during any given year. Those who are
successful at preventing this relapse take action immediately when
their weight increases even a little bit, by modifying their diet or
stepping up their physical activity.
Q:
Why do some participants regain weight and others don't?
A: The single best predictor is how long someone
has kept their weight off. Maintaining the loss for at least two years
cuts the risk of regaining weight by more than half. We've also found
that weight gain is more likely in those who scale back their physical
activity, increase their fat intake, or start watching more television.
Unfortunately,
once people start to regain weight, very few are able to fully reverse
it. Still, 96 percent of the participants manage to stay more than 10
percent below their maximum weight, which is considered successful by
obesity experts.
