The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.

Promotes the recognition, treatment, and prevention of conditions of overweight and obesity in the United States.

"The first-ever weight-loss plan specifically designed to stop-and reverse-age-related weight gain and muscle loss, while shrinking your belly, extending your life, and creating your healthiest self at mid-life and beyond"--

In the 2001 Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity, former Surgeon General David Satcher, MD, PhD, warned of the negative effects of the increasing weight of American citizens and outlined a public health response to reverse the trend. The Surgeon General plans to strengthen and expand this blueprint for action created by her predecessor. Although the country has made some strides since 2001, the prevalence of obesity, obesity-related diseases, and premature death remains too high.

#1 NEW YORK TIMES BESTSELLER • The game-changing author of The 4-Hour Workweek teaches you how to reach your peak physical potential with minimum effort. “A practical crash course in how to reinvent yourself.”—Kevin Kelly, Wired Is it possible to reach your genetic potential in 6 months? Sleep 2 hours per day and perform better than on 8 hours? Lose more fat than a marathoner by bingeing? Indeed, and much more. The 4-Hour Body is the result of an obsessive quest, spanning more than a decade, to hack the human body using data science. It contains the collective wisdom of hundreds of elite athletes, dozens of MDs, and thousands of hours of jaw-dropping personal experimentation. From Olympic training centers to black-market laboratories, from Silicon Valley to South Africa, Tim Ferriss fixated on one life-changing question: For all things physical, what are the tiniest changes that produce the biggest results? Thousands of tests later, this book contains the answers for both men and women. It’s the wisdom Tim used to gain 34 pounds of muscle in 28 days, without steroids, and in four hours of total gym time. From the gym to the bedroom, it’s all here, and it all works. You will learn (in less than 30 minutes each): • How to lose those last 5-10 pounds (or 100+ pounds) with odd combinations of food and safe chemical cocktails • How to prevent fat gain while bingeing over the weekend or the holidays • How to sleep 2 hours per day and feel fully rested • How to produce 15-minute female orgasms • How to triple testosterone and double sperm count • How to go from running 5 kilometers to 50 kilometers in 12 weeks • How to reverse “permanent” injuries • How to pay for a beach vacation with one hospital visit And that's just the tip of the iceberg. There are more than 50 topics covered, all with real-world experiments, many including more than 200 test subjects. You don't need better genetics or more exercise. You need immediate results that compel you to continue. That’s exactly what The 4-Hour Body delivers.

The Roundtable on Obesity Solutions of the National Academies of Sciences, Engineering, and Medicine held a workshop in Washington, DC, on April 6, 2017, titled The Challenge of Treating Obesity and Overweight: A Workshop. The discussions covered treatments for obesity, overweight, and severe obesity in adults and children; emerging treatment opportunities; the development of a workforce for obesity treatments; payment and policy considerations; and promising paths to move forward. This publication summarizes the presentations and discussions from the workshop.
