Healthy weights defined Many definitions: A healthy body weight is not a number on a scale. There is no ideal weight that suits everyone. Body weight is only one component of your health Factors such as age, family history, stress, sleep habits, and lifestyle will affect your weight
Causes of obesity Adapted from Ritenbaugh C, Kumanyka S, Morabia A, Jeffrey R, Antipatis V.

Unhealthy eating Low or no physical activity Smoking will increase the risk of health problems regardless of your size
Ways to measure healthy weights BMI – body mass index You can calculate your BMI easily by using this simple formula: WEIGHT (KG) WEIGHT (KG) HEIGHT (M) x HEIGHT (M)
BMI Body mass index Limitations Charts to refer to What should you do if you are over?
Health Risk Classification According to Body Mass Index (BMI) ClassificationBMI Category (kg/m 2 ) Risk of developing health problems Underweight< 18.5Increased Normal Weight Least Overweight Increased Obese class I High Obese class II Very high Obese class III>= 40.0Extremely high Reference:
BMI and Waist Circumference Risk of Disease Body Mass Index (BMI) Normal BMI = Overweight BMI = Obese BMI = >30 Waist Circumference (WC) <102 cm (Males) Least riskIncreased riskHigh risk <88 cm (Females) >=102 cm (Males) Increased riskHigh risk Very high risk >=88 cm (Females) Reference:
Waist – to – Hip Ratio Where fat is distributed on the body can be a good indicator of overweight/obesity. A lot of fat deposited in the abdominal area can put someone at increased risk of obesity related diseases. To carry out this calculation, you need to measure (in cm or inches) your waist at the narrowest part – just above the navel. Make a note of the measurement then do the same around your hips at the widest possible part. Your waist to hip ratio is then determined by dividing the waist measurement by the hip measurement. WAIST (cm/inches) HIP (cm/inches) For an average man, a ratio of 0.94 and above poses a health risk. The average woman – a ratio of 0.82 and above defines risk. Note – If you want to be as accurate as possible, take 3 different measurements for each area. Use the smallest measurement of the three for your waist, and the largest for your hip.

What to do? Behaviour change Healthy eating Physical activity
Canada’s Physical Activity Guide 4 guides What is the amount of exercise required to maintain a healthy weight
Build into your day Build physical activity into your day Add up 10 minutes of activity blocks Combine your activities to include: endurance (increase your heart rate), flexibility, (improve your balance & coordination), strength (build your muscles and bones) with weight bearing activities
Canada’s Food Guide to Healthy Eating Also included in physical activity guide Getting a variety balance of healthy foods from all of the four food groups Highlight serving sizes and that fact that portions eaten in meals or snacks are often not equivalent to serving sizes (usually portions eaten are larger, so need to recognize multiple servings are eaten)
Canada’s Food Guide to Healthy Eating Four food groups Choose whole grain and enriched products Choose dark green and orange vegetables and orange fruit Choose lower-fat milk products Choose leaner meats, poultry and fish, as well as dried peas, beans and lentils Emphasizes variety and moderation
Canada’s Food Guide to Healthy Eating (cont’d) Serving sizes defined in the Food Guide are usually not the same as portion sizes eaten in meals or snacks portions eaten tend to be larger than Food Guide servings Example: ½ cup pasta = 1 serving; if a portion eaten is 2 cups, then this equals 4 servings

Fad Diets? Examples: Dr. Atkins, South Beach, The Zone Pitfalls of dieting: Do they work in the long run? Pitfalls of over-exercising Discussion about effectiveness of dieting vs. making small sustainable changes to improve healthy eating habits
Finding the balance Making the equation work for you Formula energy in (food) + or – energy out (physical activity) = + or – weight maintenance energy in (food) + or – energy out (physical activity) = + or – weight maintenance
Overcoming the barriers What can you do to get the right balance?
How can we do this in our fast paced world? Barriers to healthy eating, and getting enough exercise Discussion of barriers
