Dietary Practices, Dining Out Behavior, and Physical Activity Correlates of Weight Loss Maintenance
Loss of excess weight can improve blood lipids, insulin sensitivity, and blood pressure. However, data are scant on behavioral strategies related to maintenance of weight loss. We examined dietary practices, physical activity, and self-efficacy among adults self-reported to be successful at maintaining weight loss.

Factors Influencing Lunchtime Food Choices Among Working Americans*
As employers realize the benefits of achieving and maintaining a healthy workforce, increased attention is being focused on the usefulness of the workplace as a site for health promotion. Programs may include environmental modifications, such as changes in foods offered in the cafeteria and in vending machines, and the provision of health services, such as education and counseling. Providing access to healthy food choices such as fruits and vegetables on-site may increase healthful behaviors among employees. Convenient access is important in a society that experiences time constraints because of the increased prevalence of employed parents and pressure to increase productivity at work by working longer hours.

Fruit and Vegetable Consumption Among Adults
A diet high in fruits and vegetables is associated with decreased risk for chronic diseases. In addition, because fruits and vegetables have low energy density (i.e., few calories relative to volume), eating them as part of a reduced-calorie diet can be beneficial for weight management.

Prevalence of Fruit and Vegetable Consumption and Physical Activity by Race/Ethnicity
The National Cholesterol Education Program and the American Cancer Society both emphasize lifestyle modifications that include diet and physical activity to reduce disease risk. These are also two of the strategies implemented by states participating in CDC's Nutrition and Physical Activity Program to Prevent Obesity and Other Chronic Diseases.

Still Not Enough: Can We Achieve Our Goals For Americans To Eat More Fruits And Vegetables In The Future?*
The majority of U.S. adults continue to consume fewer than five servings of fruits and vegetables daily. This is a public health concern because consuming a diet high in fruits and vegetables is associated with a decreased risk of certain chronic diseases, such as cardiovascular disease, diabetes, and some cancers

Trends in Fruit and Vegetable Consumption Among U.S. Men and Women, 1994—2005
Assessing trends in consumption of these foods is important for tracking public health initiatives to meet this goal and for planning future objectives. The frequency of fruit and vegetable consumption changed little from 1994 through 2005. If consumption is to be increased, promising individual and environmental strategies need to be indentified and disseminated, including policy change.
