What do YOU think are the most critical factors influencing the obesity epidemic/crisis. Pick only 1-2 causes to focus on in-depth (clearly, all of the causes are important, but what do you find most interesting, compelling), as well always back up your discussion with information from the textbook and other quality sources.
For your original posting: discuss WHY you believe this factor(s) is such an important contributor. Bring in information from the text and other resources. Additionally, pretend you are a nutritionist and have a client grappling with your top factor(s): how would you educate him/her so he/she could understand it more and deal with the issue?
