### Limit Screen Time People who spend many hours watching TV, playing video games, or scrolling through social media are more likely to be affected by overweight or obesity. Watching TV and using social media increase exposure to advertisements for less-nutritious foods and beverages. In the US, food and beverage companies spend billions of dollars a year in advertising often aimed at children and teens. More than one-half of advertisements seen by children and teens relate to food. The majority of these advertisements are for fast foods, snack foods, and sugar-sweetened drinks. Predictably, viewing these advertisements increases children's interest in such products. One study estimated that a ban on fast-food advertising during children's programs could reduce the number of teens affected by overweight by 14 percent. ### Enlist Support Changing eating and physical activity behaviors is difficult. To have support from those around you, simply having a friend go to the gym or go for walks with you can help. Tell friends or members about your goal and ask them to support. Some people participate in formal groups to lose weight. These healthy competitions are effective because they provide social support and provide healthier foods for children. The best results occur when family members are involved. It is a good idea to consult with a healthcare professional when struggling with weight management. These professionals can determine the weight-management strategy best for your health. ### Lesson 8.4 Review #### Know and Understand 1. How do genes influence weight? 2. Explain how calorie balance can lead to weight gain, loss, or maintenance. 3. Why is BMI an imperfect tool for assessing weight status? 4. Why is the waist-to-hip ratio method of measuring body-fat distribution not recommended for teens? 5. What are the health consequences of overweight and obesity? #### Think Critically 6. With a partner, discuss the following sentence: Your ideal weight is the weight at which your body is healthy. What does this sentence mean? Do you think most teens agree with this sentence? What factors influence whether a particular weight is healthy for someone? 7. Why are fad diets not a good method of weight management? Choose one fad diet and explain how effectively it can be used to maintain the weight loss associated with the fad diet. 8. For one week, keep a food diary, recording everything you eat at the end of every day. Given that you maintain a diary about nutrition, are there any adjustments you would make to have a healthier eating pattern? 9. How does a "mind-set" about weight-management undermine weight-loss efforts? ### REAL WORLD Health Skills Select one factor that can influence a person's weight. Research its impact using reliable resources. In your research, explain how this factor affects you and how a person can use it to maintain weight. Then, using your research, set three SMART goals for this factor. Explain how each goal will help you manage your goal to act on.
