Body Types Before the bell: 1.Get out your journal. 2.If you have a calculator…it would be very useful to have today…get it before class starts, do not ask me to go to your locker for it!
Journal The man on the video stated that a person could be “fat but fit”. 1.How is this possible? 2. What should healthy weight be based on?
Body Image A person who feels good about the way she or he looks is more likely to have a positive self-image. Trying to look the same as a model, an athlete, or anyone else is not a healthy approach to body image. It’s important to recognize and accept that there are differences in body type- no individual weight or body type is ideal at any age. Pg. 99
Body Types Mesomorph: Square, heavily muscled, athletic build Endomorph: Round body, little muscle definition, high body fat % Ectomorph: Thin, long limbed, possibly tall, little muscle definition Most people are medial (combination of these three body types).
Your Appropriate Weight Many factors influence your appropriate weight, or the weight that is best for your body. These factors include your gender, height, age, and body frame (small, medium, large), and, during your teen years, your growth pattern. Pg. 99
Weight Problems Being overweight or underweight is unhealthy. Many teens are concerned that they have a weight problem. In reality, most teens don’t need to lose or gain weight. In fact, unwise dieting can interfere with normal growth and development. Pg. 100
Overweight Eating empty-calorie foods or eating more food than needed leads to weight gain. Weight gain is also linked to a sedentary, or inactive lifestyle. Excess weight puts strain on the heart and lungs. Overweight people have an increased risk of developing high blood pressure, diabetes, heart disease, cancer, and stroke. Pg. 100
Underweight Some people are underweight because they do not consume enough nutrients. Others are underweight because of extreme dieting or excessive exercise. People who are underweight many not have enough body fat to cushion the body’s organs and bones. They may often feel tired due to insufficient food energy, and they have little body fat as an energy reserve. Underweight people are also more likely to develop disorders related to a low food intake, such as anemia. Pg. 100
The Role of Calories The more calories a food contains, the more energy it provides. When you take in the same number of calories that your body burns, your weight remains the same. On average, teen females require 2200-2500 calories per day, and teen males require 2500- 3000. A healthful eating plan is based on foods with high nutrient density. Pg. 100
Reaching your Appropriate Weight Most successful weight change programs combine increased physical activity with a healthful eating plan, including mostly nutrient-dense foods. Managing Weight Change Use critical-thinking skills to analyze weight modification practices. Select appropriate practices to maintain, lose, or gain weight according to your individual needs and sound scientific research. Pg. 101
Weight Management Balance caloric intake with caloric expenditure.
So what do I eat??? -Eat foods from every food group every day. -Eat a variety of foods every day. -Eat everything in moderation.
Appropriate weight is should be based on several different measures including body fat percentage and BMI (Body Mass Index). Body fat percentage is the ratio of fat to muscle or your body composition. Body fat percentage can be measured in several different ways. -calipers -electrical impedance scales -hydrostatic weighing Body fat percentage is subject to error just like any other body weight measurement.
BMI is the ratio of height to weight. BMI can be measured with a mathematical calculations. BMI is subject to error just like any other body weight measurement.
Calculate BMI 1.Multiply your weight in pounds by 703. 2.Divide the result from step 1 by your height in inches. 3.Divide the result from step 2 by your height in inches. 4.The final number you calculate will be your BMI. Line up your BMI with your age and determine which category you fall into. **REMEMBER, BMI IS NOT 100% ACCURATE BUT IT DOES GIVE A MORE RELIABLE MEASURE THAN A SCALE.
