Sarah Kim Professor Richard Andrews Kin 346: 17998 1 May 2015 Study Questions—Chapter 22 1. What is the difference between overweight and obesity? Overweight is body weight that surpasses the normal weight for a specific height and body size.  Obesity is extra body fat—specifically, over twenty-five percent body fat for men and over  thirty-five percent for women. 2. What is the ideal body weight, and how is it determined? The ideal body weight is having a body mass index between 18.5 to 24.9 kg/m^2. The body mass index can be determined by diving kilograms by meters (of body height) squared. 3. What is body mass index? What is its significance? Body mass index (BMI) is a clinical standard that estimates body fat from the ratio of total body  weight to height. The significance of the BMI is that an individual can be classified as  underweight normal weight, overweight, obesity, and extreme obesity according to his BMI  number. 4. What is the prevalence of obesity in the United States today? Is there a difference in the  prevalence between men and women? Children and adults? Blacks and whites?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
