Nutrition weight gain

Nutrition for Weight Gain

Because weight is influenced by energy (calories) consumed and expended, interventions to improve weight can support changes in diet or physical activity. They can help change individuals’ knowledge and skills, reduce exposure to foods low in nutritional value and high in calories, or increase opportunities for physical activity. Interventions can help prevent unhealthy weight gain or facilitate weight loss among obese people. They can be delivered in multiple settings, including health care settings, worksites, or schools.

Social and Physical Determinants of Weight

The social and physical factors affecting diet and physical activity (see Physical Activity topic area) may also have an impact on weight.

Obesity is a problem throughout the population. However, among adults, the prevalence is highest for middle-aged people and for non-Hispanic black and Mexican American women. Among children and adolescents, the prevalence of obesity is highest among older and Mexican American children and non-Hispanic black girls. The association of income with obesity varies by age, gender, and race/ethnicity.

Emerging Issues in Nutrition and Weight Status

As new and innovative policy and environmental interventions to support diet and physical activity are implemented, it will be important to identify which are most effective. A better understanding of how to prevent unhealthy weight gain is also needed.
