Excess weight gain occurs when more calories are consumed than expended over a long period of time. Accurate translation between changes in calories and changes in weight is important for setting goals and for evaluating interventions at both the individual and population levels. For years, a simple rule of thumb has been used for predicting weight change: 3,500 calories equals one pound of body weight change. However, emerging research demonstrates that the math is not that straightforward, and the 3,500-calorie rule will create overly optimistic predictions of weight loss, oftentimes being in error by many fold. This brief presents new mathematical models that can be used to calculate the impact of calories on body weight in both adults and children, and several useful rules of thumb that can estimate changes at the population level. These models suggest that the obesity epidemic was driven by much larger changes in calorie intake than previously believed and will require aggressive strategies to reverse.
From Calories to Weight Change in Children and Adults: The State of the Science
Farm-to-School Education Grants Reach Low-Income Children and Encourage Them to Learn About Fruits and Vegetables
For children from low-income families, school meals are a significant portion of daily caloric intake and hence an opportunity to address food insecurity. Many states have pursued legislation to institutionalize programs such as farm to school that aim to improve the quality of school meals and acceptance of healthy foods … More
One of the most pressing unmet challenges for preventing and controlling epidemic obesity is ensuring that socially disadvantaged populations benefit from relevant public health interventions. Obesity levels are disproportionately high in ethnic minority, low-income, and other socially marginalized U.S. population groups. Current policy, systems, and environmental change interventions target obesity-promoting … More
Technical Scientific Report. Healthy Beverage Consumption in Early Childhood: Recommendations from Key National Health and Nutrition Organizations
Research shows that what children drink – from birth through age 5 – can have a big impact on their health, as beverages make a significant contribution to dietary intake during this period. However, with so many choices available in the marketplace, it can be confusing for parents and caregivers … More
