The Science behind the PointsPlus

The PointsPlus program does not waiver from this foundation, but rather incorporates advances in science and nutrition as it relates to weight management. It has been tested in a rigorous, independent clinical trial, and the results demonstrate it delivers significant weight loss as well as improvements in cardiovascular risk factors and eating behaviors linked with long term weight loss and hedonistic hunger (an urge to eat when the body does not have a biologic need to).

The PointsPlus Formula

The PointsPlus formula uses the grams of total fat, carbohydrate, dietary fiber and protein to calculate the assigned PointsPlus value. While creating a caloric deficit is at the core of weight loss, the formula accounts for the fact that the body uses calories differently, depending on a food’s nutrient composition.

To gain a greater understanding of how the PointsPlus formula works, it’s important to understand the difference between food calories and human calories. Nutrition information on a food package in the grocery store provides the number of calories in that food which is based on the Atwater system developed in the late 1800s. The calories on a nutrition label do not reflect the processing the body must do to convert those food calories into calories the body can use. This conversion process takes some work and the amount of work depends on the nutrients involved. Protein and fiber have the highest conversion costs. Fat has the lowest conversion cost, while non fiber containing carbohydrates require a bit more work. 3,4 The conversion cost of each of these nutrients is factored into the PointsPlus value of a food so that it reflects the calories your body has available for use as opposed to simply the calories available from the food itself. While the calorie providing nutrients vary in their conversion cost, it has also been recently discovered that they are also quite different in providing feelings of fullness (or satiety). And, interestingly, the progression of nutrients for conversion cost and the progression of nutrients for satiety are the same. Research has shown that protein is more filling wholesale nfl jerseys from china than carbohydrate and carbohydrate is a bit more filling than fat. 5,6,7 Fiber calories are not only limited in their availability to the body, they are also linked with feelings of increased fullness.8 As a result, the PointsPlus formula guides food choices beyond reducing overall calorie intake to enhance feelings of satiety.

Weight Watchers Power Foods

The Power Foods provide a way to easily and quickly pick the food choices that are most nutritious as well as most satisfying when working to lose weight. They are a list of diverse foods that are highlighted due to their low energy density and healthfulness (taking into consideration the total fat, saturated fat, sugar, sodium and/or fiber content). The foods within each category were ranked using a proprietary formula tailored to the category. The foods that rose to the top of the list meaning they had a lower energy density, less fat , saturated fat, sugar, sodium, and/or higher in fiber were identified to be Power Foods.

There is strong clinical evidence to demonstrate that a low energy density, nutritious diet is important to weight management as well as good health because of the nutrients they contain as well as their ability to increase satiety.9,10 The Power Foods provide an easy way to incorporate this scientific research into day to day food choices. These food selections also provide a means to implement the recommendations put forth in the cheap nfl jerseys 2010 Dietary Guidelines for Americans in an uncomplicated way.11

0 PointsPlus Fruits and Vegetables

In the PointsPlus program, all fruits and most vegetables have a PointsPlus value of 0. This feature promotes the intake of these foods as research shows that most individuals fall significantly short on including the recommended intake into wholesale jerseys their diet.12 At the same time, it is well established that these foods are critical to ensuring good health and are filling, satisfying choices. To ensure weight loss, the daily Target has been adjusted to account for the calories coming from fruits and vegetables. A randomized clinical trial was also done where individuals followed the program with this feature and the researchers found that it did not hinder weight loss.

The PointsPlus Program Works

Development of a weight loss system based on scientific concepts and theories doesn’t prove that it will work in the real world. Knowing this, Weight Watchers has extensively tested the PointsPlus program. Participants have included current Weight Watchers followers, past Weight Watchers participants, and those who have never followed Weight Watchers. In addition, a 12 week, prospective, randomized clinical trial was cheap jerseys performed by an independent research group at a large medical university. Some results of this trial have been published in the scientific literature.1,2,3,4 Further manuscripts are under development and review.Articles Connexes:
