Study Tests Portion-Controlled Entrees
Are They Effective For
A new study just published in the March
2004 issue of Obesity Research compared two groups of women
trying to lose weight. One group consumed a recommended number of servings
from the federal Food Guide Pyramid each day, while a second group
consumed a similar diet, but utilized two pre-packaged entrees daily. The
According to data published in
the findings report entitled, Use of Portion-Controlled Entrees
Enhances Weight Loss In Women,
of portion-controlled entrees resulted in greater losses of weight and
fat, thereby reducing cardiovascular disease risk. Accurate portion
control is an important factor in weight loss success, and use of packaged
entrees is an effective method of achieving this."

Consumption of a diet using portion-controlled entrees
enhances weight loss success.
The study, conducted by
researchers at the University of Illinois and supported by a grant from
Masterfoods USA, set out to determine the efficacy of a weight-loss diet
using packaged, portion-controlled entrees compared with a self-selected
diet based on the U.S. Department of Agriculture Food Guide Pyramid (FGP).
For an 8-week study period, 53 women were recruited and randomized into
two groups. Each was instructed to consume her group's respective diet
plan (see sidebar on right), and both groups were given clear,
straightforward instructions but no individual behavioral and diet
counseling. All subjects came in once per week for a meeting with the
research dietitians and to be measured.
In the end, both groups
achieved significant weight losses over the 8 weeks of the study, but the
group which utilized the portion-controlled entrees lost 6.5% of their
initial weight—more than a third more than the group that didn't utilize
U.S. Department of Agriculture FGP does offer reasonable guidelines on how
much to consume from each of the various food groups. Choosing the lowest
number of servings from each group provides a workable weight loss diet
plan. However, a concerted effort is required to choose, prepare, measure
and consume foods in the recommended portion sizes."
The scientists went on to say
both groups in this study attempted to follow a 1365-calorie diet plan
based on serving sizes used in the FGP, those using packaged,
portion-controlled entrees were more successful in achieving significant
reductions in weight and body fat. For many people who want to lose
weight, portion control may prove to be a key factor."
These findings, regarding the
role of prepackaged foods and the importance of portion control, are not
surprising. Study outcomes similar to these are becoming more and more
prevalent as researchers tackle America's snowballing obesity epidemic,
and one of its main culprits, the over consumption of food.
As published last year in
The Journal of the American Medical Association (JAMA), a study done by
researchers at the University of North Carolina regarding average
consumption since the 1970s, proved that portion sizes are indeed on the
rise. Experts analyzed the food intake of more than 63,000 Americans
during ongoing National Food Consumption Surveys and compared the average
portion sizes of snacks, desserts, soft drinks, fast food, pizza and
"When I came home at 6:00 at night, I didn't have to
think about what I was going to eat or how much I was going to
eat. It was all right there for me. I could just pull it off
the shelf. It was a balanced meal. It was portion-controlled
and it was something that I could prepare just in
minutes." – Carole, NutriSystem Success
NutriSystem, we know how important portion size is. That's why
we built our entire program around it!
Their findings? Throughout the
past 20 years, portions have grown significantly in all environments.
Between 1970 and 1996, here's how some average portion sizes grew:
Salty snacks (chips,
pretzels) --- Up 60%
Soft drinks --- Up 52%
Hamburgers --- Up 23%
French fries --- Up 16%
Additionally, among those
39-and-younger, pizza and salty snack food consumption had increased by
more than 140%!
These ongoing studies may help
to shed more light on the snowballing obesity epidemic overtaking our
nation. As Jeff Prince, Vice President of the American Institute for
Cancer Research said in a press conference coinciding with the Institute's
International Research Conference on Food, Nutrition and Cancer last
"In a country where 64%
of us are overweight or obese, there is an alarming tendency to overlook
the sheer amount of food we're eating. We have to regain our sense of
appropriate portion size, so we can better gauge our intake."

Before that question can be
answered, we have to understand what ‘juice fasting’ is about.
Juice fasting is about abstaining
from solid food, for a period of time, while supplying your body with the most
nutritious drinks on this planet. By providing essential vitamins and minerals,
the juice can actually jump-start the body’s fat-burning mechanisms. One glass
of freshly-made fruit or vegetable juice provides you with the equivalent
vitamins, minerals, enzymes, amino acids and chlorophyll you would get by eating
several pounds of raw fruits and vegetables.
Most of us have heard how thousands
are losing up to 10 pounds in 2 days on the best-selling Hollywood 48-Hour
Miracle Diet in which you simply juice fast on bottled (dead) juice for 2
days. Well, juice fasting is a healthier version of the Hollywood Diet because
you can fast longer than 2 days while supplying your body with live enzymes and
nutrient-rich fresh fruit and vegetable juices.
Dr. Shelton, a great advocate of
fasting, wrote "The weight lost by overweight patients in the early
days of a fast is astounding. I have seen losses of five and six pounds a day
for the first few days. A woman who fasted in the Health School in January and
February of 1950 lost twenty-five pounds in the first two weeks.
