There is no doubt we are eating more. Back in 1950s a hamburger weighed a mere 2.4 oz (68 grams). Fast forward to 2012, and hamburgers and fries are three times bigger than their ancestors. What about soda? A regular serving of soda is six times larger than it was back then.
This evolution of portion sizes is directly corelated to our drastically larger waistlines. This fast food infographic from the U.S.Center for Disease Control (CDC) reflects the growing rate of obesity in industrialized countries. Health experts agree that this ''new (ab)normal trend'', as the CDC calls it, must be reversed if we are to stay healthier. For more facts, check out our A to Z hamburger guide.
