I would limit it. Why don't you document the food intake of a group of teens?
how can i do community service about this topic
Post a poster with the results in the school cafeteria, write a news article, etc.
what can be inclued in the senior project about it
Did you read through the web sites I posted???
yes just need a little more
How about following Bobpursley's advice about doing a poster for the school lunchroom. Research the amount of calories needed for a normal teenager.
I can envision a poster with two columns or sections.
In one section, have a picture of a slim, attractive person. Then show a reasonable day's food intake with quantities and calories for each.
In the other section, have a picture of an obese person. Show the food that an obese person might eat in a day. Again include quantities and calories for each.
I have an obese friend who eats two or three times the amount I do at each meal. When one piece of candy satisfies me, she eats three or four pieces of that candy. The same is true of everything else I've seen her eat.
