Another
reason many people find it hard to maintain weight loss is that they set their
hearts on losing, say, 40
pounds, and when they find out it requires too great a
sacrifice, they give up, blaming themselves or their genes.
Heredity
does play an important part in shaping our shapes. Genes, for example, can make
the body inefficient at burning fat or make metabolism sluggish. Studies on
identical twins confirm that when one twin is overweight, the other one usually
is, too--an association that occurs far less often in fraternal twins, who
don't inherit the exact same genes.
Still,
biology isn't destiny. Even among identical twins, weights can be far apart.
Fletcher cites the case of one man who was inspired to slim down because he was
50 pounds
heavier than his identical twin, who'd always been more active.
"Genes
set the lower and upper limits of your weight," says Hill, "but it's
lifestyle that moves you up or down within that range." Not surprisingly,
a lifestyle that consists of sitting in front of the television eating
cheeseburgers is more likely to push a person to the right of the range, into
the fat zone, than to the left.
When trying
to set a realistic weight goal, adds Fletcher, ask yourself these questions:
What is the least you've weighed as an adult, for at least a year? What is the
largest size clothing you'd be happy with? (Would you settle for a size 14,
say, instead of a 107) What weight were you able to maintain during previous
diets without feeling constantly hungry? Many of the dieters she surveyed found
that their original weight goal was too low to maintain comfortably; those who
succeeded were willing to settle for a more realistic target.
Losing just
5 to 10 percent of your current weight, surveys show, brings major physical and
psychological benefits. "You might not become the skinny person of your
dreams," says Foreyt, "but even a small loss can make you feel better
about yourself."
Don't
Deprive Yourself
When she
first began her research, Fletcher wasn't much interested in how dieters lost
weight. Instead, she wanted to find out how their eating habits changed
afterward. But, in talking to many dieters, she quickly learned that the issues
couldn't be separated. The more extreme the original diet, they told her, the
harder the transition to a maintenance diet.
Still, one
common thread showed up among all those who succeeded: No matter how weird or
wacky their diet started out, they eventually adopted a sensible eating plan
they were content to stay on the rest of their lives. How did they do it? For
one thing, they made sure not to deny themselves their favorite foods.
Other
studies back up that finding. Health educator Susan Kayman studied 74 women
enrolled in Kaiser Permanente Medical Offices in Fremont, California,
who'd lost a lot of weight. She discovered two behaviors that distinguished
those who maintained a significant weight loss from those who didn't. The
successful dieters weren't as rigid about what they ate, and they didn't feel
deprived. Instead, they compromised on portions.
"One
woman would take a half gallon of ice cream, cut it into cubes, and wrap each
cube individually so she wouldn't devour the entire carton at one
sitting," says Kayman. While that may strike some as a bit obsessive, it
illustrates how successful dieters find ways to make their diet work for them.
Kayman speculates that because they don't label any foods forbidden, they're
able to indulge without triggering feelings of guilt. Dieters with an
all-or-nothing mentality inevitably give up when they stray even a little.
The actual
indulgence may matter less than the sense of control it imparts, says Fletcher.
She describes one woman who joined Weight Watchers at a time when the program
was more restrictive. The only way she could tolerate staying on the program
was to "cheat" by eating three chocolate chips every day. The tiny
extravagance paid off: She lost 57 pounds, and she's kept them off for 20
years.
Cut the Fat
When
fletcher asked successful dieters to name the three most important factors in
keeping weight down, the number-one diet-related response was "watch my
fat intake."
No wonder.
Gram for gram, fat has more than twice the calories of carbohydrates. That's
not all. Researchers have found that certain individuals are inherently bad at
burning fat. That means their bodies go to extraordinary lengths to store fat
in fat cells rather than burn it for energy. To lose weight, then, these people
may have to restrict the fat in their diets to as little as 15 percent of
calories--much lower than the currently recommended 30 percent. That works out
to 34 grams
of fat a day on a 2,000-calorie diet, or roughly 49 fewer grams than the
average American gets each day.
Hill
believes that it's important to watch fat intake, even if you're not a low fat
burner. That's because as fat stores shrink, the rate of fat oxidation-how much
fat the body burns for energy-drops. The result, says Hill: "If you eat
the same proportion of fat in the diet as you did before you lost weight,
you'll be more likely to store that fat in fat cells."
Rest
assured, cutting the fat doesn't have to mean leading a spartan life. One man
from the registry who lost more than 100 pounds likes to toss enormous salads with
his own "thousand island" dressing, made from fat-free yogurt,
ketchup, and pickle relish. Others created their own low-fat versions of
muffins, potato salad, pizza, lasagna, enchiladas, even pasta-shrimp primavera.
Many successful dieters made finding tasty low-fat foods into an enjoyable
hobby. As one put it: "Once low-fat was a permanent way of life for me,
the search for great low- or no-fat chocolate treats began."
Get Moving
It's
telling that A whopping 96 percent of people listed on the registry exercise
regularly. Moving around, after all, keeps energy levels up, fends off stress,
and contributes to a general sense of physical and emotional well-being. What's
more, by burning extra calories, exercise helps to compensate for the metabolic
drop that usually comes with weight loss.
Consider a
hypothetical 5 foot
8 inch
woman who for years weighed 150
pounds, which she maintained on a diet of 2,500
calories. Let's say she slimmed down to 135 pounds. According to
researchers at New York's Rockefeller University,
that 15-pound loss (10 percent of her weight) results in a 15 percent drop in
the number of calories she burns. So unless she exercises to make up all or
part of the difference, she can eat no more than 2,125 calories a day without
gaining weight.
Another
study illustrating the benefits of exercise involved 110 overweight Boston city workers who
went on spartan diets of 420 to 1,000 calories a day. Only half the
participants exercised--for 90 minutes, three times a week. Two months later,
the sedentary dieters and the exercising dieters both had lost about 25 pounds. But after a
couple more months, only the exercisers had maintained the loss.
Similarly,
when psychologist John Foreyt reviewed the existing weight studies, he found
several factors that predicted success. Among them were getting continued
emotional support and maintaining normal eating habits, such as sitting down to
three meals a day. But topping the list was physical activity. "Ninety
percent of people who lost weight and kept it off were regular
exercisers," says Foreyt.
