As an addendum to my rant against pro-fat people, here's a weight loss tip: switch to diet soda.
In 1997, the average American drank 1.5 12-ounce servings of soda per day -- more than 200 calories, depending on the soda. Teenagers and twenty-somethings drank 2 servings per day, for 300 calories or so. An average American in 1992 consumed 3642 calories per day (that seems too high to me), so a young adult drinking two sodas a day is getting nearly 10% of their calories from that sugary source.
Such a person could [simplification] lose 10% of their weight by switching to diet soda. Plus, it's better for your teeth.
