PSYC 2013 (Summer 2015, Escobar) Chapter 11, part 2 Week 7 1 Psychological Science Chapter 11, part 2 Eating and Health 11.2   Disorders   of   Eating Learning   Objectives Discuss   the   causes   and   consequences   of   obesity. Understand   disorders   of   eating. Review   the   benefits   of   regular   exercise. Obesity   and   Maladaptive   Eating   Habits Have   Many   Health   Consequences Body   mass   index   (BMI):   a   ratio   of   body   weight   to   height,   used   to   measure   obesity People   with   BMIs   over   25   are   considered   overweight,   whereas   those   with   BMIs   over   30   are   considered   obese. BMI   may   not   be   the   best   measure There   are   at   least   two   problems   with   the   use   of   BMI   to   predict   health. BMI   does   not   take   age,   sex,   bone   structure,   or   body fat distribution into account body   fat   distribution   into   account A   clear   relationship   between   BMI   and   health   outcomes   does   not   exist   except   for   the   very   obese.

PSYC 2013 (Summer 2015, Escobar) Chapter 11, part 2 Week 7 2 Healthy   BMI? A   recent   meta analysis   looked   at   97   studies   that   included   nearly   3   million   individuals. People   with   BMIs   of   25 30   had   a   lower   probability   of dying from any cause during the study periods of   dying   from   any   cause   during   the   study   periods   than   people   with   recommended   BMIs   <   25. Individuals   with   BMIs   >   35,   however,   were   much   more   likely   to   die. Individuals   with   low   BMIs   are   at   increased   risk   for   premature   death,   particularly   if   they   are   elderly. Healthy   BMI? Another   meta analysis   examined   32   studies   of   nearly   200,000   people   over   age   65. Those   with   BMIs   around   28   had   the   fewest   deaths and those whose BMIs < 23 or > 34 were deaths,   and   those   whose   BMIs   <   23   or   >   34   were   much   more   likely   to   have   died. Take home   message:   being   slightly   over   the   recommended   BMI   is   not   as   unhealthy   as   once   believed   and   may   even   be   protective. Obesity   and   Maladaptive   Eating   Habits Have   Many   Health   Consequences Maladaptive   eating   habits,   such   as   eating   junk   food,   are   likely   responsible   for   much   of   the   poor   health   associated   with   obesity. People who eat food high in fat and sugar tend to People   who   eat   food   high   in   fat   and   sugar   tend   to   store   more   body   fat   in   the   abdomen.

    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.
