Immune Health and Exercise
When it comes to the effects of exercise on the immune system, how much is done seems to make a difference.

Exercise Recommendations for Adults
In 2008, the U.S. Department of Health and Human Services updated its physical activity guidelines based on the report of an expert panel convened by the Centers for Disease Control and Prevention. These guidelines are the basis of physical activity recommendations in the 2010 Dietary Guidelines for Americans.

The Four Pillars of a Science-Based Approach
Weight Watchers is committed to providing a comprehensive approach to weight loss that is based on the latest scientific thinking. All too often in weight loss, a program or product is developed and then individual studies that support the program are provided to "justify" its existence.

The Four Pillars: Exercise
Weight Watchers provides a systematic approach to exercise throughout the weight-loss process.

The Four Pillars: Food
It is often said that different paths can lead to the same destination and nowhere is that more true than eating for healthy weight loss.

The Four Pillars: Behaviour
Making changes in behaviour is really at the heart of sustained weight loss, but it does not just happen. There are two specific components of behaviour change that are key components of Weight Watchers: self-monitoring and cognitive skills (cognitive is a scientific term that means how you think).

The Four Pillars: Supportive Atmosphere
Learning to create and live in a supportive atmosphere that aids weight loss is a defining aspect of the Weight Watchers experience. Weekly Weight Watchers Meetings provide Members with that essential support, as well as the information and tools, needed to achieve their goals.
