How easily you lose or gain weight is caused by heredity Your genes can control you’re amount of body fat, signals for hunger and satiety, and regulate activity However, genes aren’t fully responsible for your body shape. -Food choices and your amount of exercise are also factors Healthy weight is different for each person Having a healthy weight prevents disease from having too much or too little body fat
Body Composition- measure of the proportion of body weight that’s made up of fat tissue compared to bone and muscle Body weight alone can’t be fully responsible for whether or not you need to lose weight. A person can be over weight because of lean tissue, but not have excess body fat.
Body Mass Index (BMI)- index for weight in relation to height to show a healthy body weight. Healthy adults have a BMI between to range of 18.5-25
To measure your BMI= weight (lbs) / height (in.) / height (in.) x 703 However, your BMI doesn’t necessarily mean you are overweight because one person could have a lot of muscle and muscle is denser than fat.
Typically, teens shouldn’t aim for weight loss but to stop weight gain so they can “grow into their height” Reduce portion sizes and eat high-Calorie foods as desserts Exercising increases your energy needs and makes managing your weight easier To lose a pound a week, an average person should eat 500 fewer Calories everyday or burn 500 Calories
