July 11, 2015: Obesity
Today we focused on Obesity, with particular attention to the concept of calories and the avoidance of sugary drinks. We started off the pre-walk lecture with a demonstration to jump right in – literally! – to the concept of a calorie. With some awesome volunteers to help, we showed how it takes 15 jumping jacks to burn just 1 calorie… meaning that it would take 2100 jumping jacks to burn off all 140 calories in just one can of coke !! We discussed the importance of balancing out the calories we consume in our food with the calories we burn to avoid becoming overweight. In particular, we stressed eliminating sugary-drinks to avoid an excess of empty calories, and, in turn, avoid obesity.
We discussed some of the immediate and long-term health risks associated with being overweight, including Type 2 Diabetes, Asthma, Heart attacks, and infertility. To help make the idea of the excess and danger of sugar in sweetened drinks real, we then passed around some containers of sugar to show exactly how much sugar (9 1/3 teaspoons!) is in one can of coke.
