Research Papers / Obesity and Change, Is it Possible? [2]

Form is great.
Remember to give numberical names to as many numbers over the number 1,000 as you can -- "billion" is much easier to process than 1,000,000,000+.

Use proper terms in specifying ethnicity - Caucasian, African American, Hispanic.
Check the run-on/lengthy sentences in the introduction and first, second, and third paragraphs.

Also, consider rephrasing the title.
"Obesity: Is it the Inevitable?"
"Obesity: There Must be a Better Way"
"Obesity: A Weight on the Nation" (See what I did there?)

Overall, just be sure to do a "final draft polish". I love all the research you've done, and each paragraph seems to have a point. I like it.
