"The U.S. Centers for Disease Control and Prevention finds obesity has increased significantly over the past 20 years. Gallup's data reveal that Americans' self-reports of their own weight have also increased over the same period. Americans' average ideal weight has increased as well, showing men and women are adapting their ideal to their now higher actual weights. At the same time, the percentage of Americans who describe themselves as overweight has remained essentially unchanged over the past 20 years. While Americans are getting heavier, many may not recognize it or acknowledge it."
