Design a behavioral economics response to problems

Design a behavioral economics response to one of the two problems outlined below. You can choose either option 1 (obesity) or option 2 (energy conversation)
Depth, breadth and “multiplexity” of the analysis and its stakeholders, will determine the quality of the journal.

Option 1
A recent report released by the Trust for America’s Health and the Robert Wood Johnson Foundation used population trends and other data to predict that half of U.S. adults will be obese by 2030 unless Americans change their ways. It is estimated that 35.7% of adults and 16.9% of children aged 2 to 19 are obese, as the Centers for Disease Control and Prevention (CDC) reported earlier this year. The CDC predicts that these numbers are going to increase and exceed 60 percent in the next few years. Obesity raises the risk of numerous diseases, from type-2 diabetes to endometrial cancer. This will impose a greater burden on healthcare systems and associated costs. These projections supports a study published earlier this year in the American Journal of Preventive Medicine that found that by 2030, 42% of U.S. adults could be obese, adding $550 billion to healthcare costs over that period.
Trust for America’s Health sees an opportunity to change the growth in obese population with the right interventions. “We have learned that with a concerted effort you can change the culture of a community, including its level of physical activity, eating habits, what foods are offered in schools, and whether families eat together,” said Geoffrey Levi of George Washington University. In New York City, for instance, obesity for elementary and middle-school students dropped 5.5 percent from the 2006-07 school year to 2010-11, thanks mostly to healthier school lunches, public health experts said.

Your task
Suppose you are appointed as a consultant to develop proposals for encouraging individuals or groups to make healthier choices.
Propose a specific intervention to encourage healthy behaviors which may lower the increasing obesity rate. You could choose to focus on the U.S., or even suggest a nudge in your home country. Please specify the target group and the behavior you want to change. For example, you can focus on reducing obesity among adolescent boys or old women. Likewise, you may reduce the obesity by increasing the level of physical activity or by consuming more vegetables and less saturated fat. Think about the decision process relevant to the target behavior and the factors might cause the problem and promote the desired behavioral change. Describe what behavioral principle you are using and how your solution intervenes the decision making process in a way to induce the desired behavior. Next, please design and describe an experiment which will be helpful in testing the effectiveness of your intervention. Max 2.000 words.
