4 What is a Healthy Weight? One that will help you say healthy throughout your life Minimizes your risk of lifestyle diseases Variety of methods are used to evaluate whether a person is at a healthy weight Common methods involve determining body mass index, body fat percentage, and waist- to-hip ratio

5 Body Mass Index Ratio of weight to height Compute your BMI by doing the following: –1. Record your weight in pounds –2. Measure your height in inches –3. Multiply your weight by 703; then divide that number by your height squared (your height times itself)

6 Body Mass Index BMI 20-24 25-29 30-34 35-39 40+ Risk for health problems Very Low Risk Low Risk Moderate Risk High Risk Very High Risk

7 Body Mass Index More accurate than just your weight alone but not foolproof Examples: –Bodybuilder may have a BMI of 30 or higher –Athletes and other individuals with large muscles masses are not necessarily at risk Body fat measurements may need to be taken

8 Body Fat Percentage Used instead of BMI Amount of body fat a person has in relation to muscle Can be a more accurate measure than the BMI Can show if the extra pounds are from muscle, not fat

9 Body Fat Percentage Healthy body fat percentages for non- athletes are approximately –15 to 19 percent for males –20 to 25 percent for females Individuals above these ranges are said to be obese –Having excess body fat

10 Body Fat Percentages Athletes: –Males: 5-10% –Females: 10-20% Body fat percentages lower than these amounts can indicate an eating disorder

11 Waist-to-Hip Ratio A measurement of how fat is distributed in the body This is where the variations of body types comes into play –Pear-like shapes carry most of their fat on the thighs and hips –Apple-like shapes carry most of their fat over the abdomen

12 Waist-to-Hip Ratio Check body shape easily Stand relaxed and measure the waist without pulling in stomach Measure the hips where they are the largest Divide the waist measurements by the hip measurement gives the waist-to-hip measurement

13 Waist-to-Hip Ratio Adult women should have a ratio no higher than.80 Adult men should have no higher than.95 Ratios above these limits may increase the risk of health problems, even if BMI shows that weight is at a healthy level
