Simple diets work for weight loss
A new study shows that reducing variety in the diet may help people
lose weight and keep it off for good.
Researchers found that people who have successfully maintained
major weight loss for several years ate less of a variety of foods
within each food group than those who have recently lost weight.
They say the results show that reducing the number of different
foods, especially fatty ones, may aid in long-term weight loss
maintenance.
Prior studies have shown that eating a greater variety of high-fat
foods and lesser variety of low-fat foods tends to make people
eat more calories and hampers weight loss efforts. But researchers
say it's not clear whether food variety affects long-term weight
loss and maintenance.
In this study, which appears in Obesity Research, researchers
looked at the variety of foods eaten by people who have successfully
maintained weight loss and compared it with those eaten by people
who recently lost weight.
The more than 2,200 successful weight loss maintainers were part
of the National Weight Loss Registry. They had lost an average
of 70 pounds and kept at least 30 pounds of it off for nearly six
years. The comparison group consisted of 97 individuals who had
recently participated in a behavioral weight loss program and lost
at least 7% of their body weight.
The study showed that successful weight loss maintainers ate less
of a variety of foods in all food groups, especially those that
were high in fat, such as fats, oils, and sweets, and consumed
fewer calories overall than the others.
Although researchers had expected to find that successful weight loss maintainers
ate fewer foods that were high in fat, they say they were surprised to find
that they also ate less of a variety of low-fat foods.
Still, the greatest variety of foods eaten by the registry participants were
those at the bottom of the federal food pyramid, including breads, cereals,
rice, pasta, fruits, and vegetables. The least variety was found among foods
at the top of the pyramid, such as fats, oils, and sweets.
In fact, the biggest difference between the two groups was in the variety
of foods at the top of the pyramid with the successful weight loss maintainers
eating less of a variety of these calorie-dense foods.
Therefore, researchers say that although the weight loss maintainers had lower
overall variety in their diet, they ate a bigger variety of nutrient-rich and
low-fat foods than in other food groups.
They say reducing variety in the diet may make it simpler and easier to maintain
weight loss, but it may also make it more boring.
Tom Venuto, author of Burn
The Fat Feed The Muscle, suggests that you
create a menu using an Excel spreadsheet or your favorite nutrition software.
Once you have your daily menu, print it, stick it on your refrigerator and
you now have an eating "goal" for
the day.
"If you get bored eating the same thing every day," says Tom, "you can create
multiple menus, or just exchange foods using your one menu as a template. Using
this method, you really only need to count calories once when you create your
menus."
