In "Downsizing Supersize" by James Surowiecki he first brings the issue of 'large' drinks and their ban from New York. When first reading, I disagree with Surowiecki because people in restaurants and fast food can always ask for refills but, as I continued reading I started to agree. In a word where everything must be convenient, people don't normally go out of their way to ask for a larger drink and stick with the default option. Surowiecki also references an experiment where a bowl of M&Ms were placed with a smaller or larger scoop with the sign "Eat Your Fill". Reportedly, people took more when presented with a larger scoop. This shows that people eat as much as is presented to them and outside factors do matter.
"Why Shame Won't Stop Obesity" by Dhruv Khullar pins obesity on the availability of unhealthy, fatty foods and the need for positive affordable ways to stay healthy. In children especially, advertisements for fast food restaurants increase the craving for those foods. I think Khuller does a good job in including all perspective of healthy eating. When constantly eating from a cafeteria, it cane difficult to distinguish healthy from unhealthy and when you're a parent it can be hard to feed your children well every meal.
