Health professionals recognize the benefits associated with a healthy eating plan based on the Dietary Guidelines for Americans. Proper nutrition promotes the optimal growth and development of children. A healthy diet also helps reduce the risks for many health conditions.1

Regular physical activity helps improve a person's overall health and fitness, and reduces the risk for many chronic diseases.2 Nationally in 2015, only 20% of adults reported that they participated in enough aerobic and muscle strengthening exercises to meet guidelines3 and about half of high schools students were physically active at least one hour per day on five or more days per week4.

A person whose weight is higher than what is considered as a normal weight adjusted for height is described as being overweight or having obesity.5 Body Mass Index (BMI) is the weight-to-height ratio most commonly used to estimate and screen for overweight and obesity. Overweight is defined as a BMI of 25 or higher; obesity is defined as a BMI of 30 or higher.

Staying in control of your weight contributes to good health now and as you age. Individuals who are at a healthy weight are less likely to:
  • Develop chronic disease risk factors, such as high blood pressure and dyslipidemia.
  • Develop chronic diseases, such as type 2 diabetes, heart disease, osteoarthritis, and some cancers.
  • Experience complications during pregnancy.
  • Die at an earlier age.6
