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

Why Do You Weigh What You Weigh

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 Composition

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

Body Mass Index

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.

Weight Management

Millions of dollars are spent each year on weight loss programs. Many of the programs promise quick results, and they do, but in the long term they can cause health problems. Most of these diets do not help you maintain a healthy body weight in the long run.

Dangerous Weight-Loss Practices

Low-carbohydrate diets- these restrict carb. intake to cause fat to be broken down. These are not healthy in the long run because they are low in grains, fruits, and vegetables.

Stimulants(bitter orange, caffeine)- they reduce your appetite and give you more energy. They can cause nervousness, dizziness, headache, high blood pressure, heart attacks, and seizures.
