Facts about overweight and obesity • leading risks for global deaths. • Around 3.4 million DEATHS per year. • 44% of the diabetes burden, • 23% of the ischaemic heart disease burden • 7% to 41% of certain cancer burdens .
WHO global estimates from 2008 • More than 1.4 billion adults, 20 and older, were overweight. • over 200 million men and nearly 300 million women were obese. • Overall, more than 10% of the world’s adult population was obese.
What Causes Obesity? • Energy imbalance over a long period of time. • Energy in > Energy out. • Excess calories and lack of physical activity. Energy balance is like a scale. When calories consumed are greater than calories used, weight gain is the result. CDC
Calories Used • Eating, digestion, sleeping, breathing, and movement. • Excess calories. • Physical activity. Energy Balance Necessary physiological functions Calories in Calories used (consumed) (expended) Physical activity Food/beverages consumed CDC

How Much Physical Activity a Day? The 2005 Dietary Guidelines for Americans recommend the following for adults: • To reduce the risk of chronic diseases in adulthood: Engage in at least 30 minutes of moderate-intensity physical activity, above usual activity, at work or home on most days of the week. • To help manage weight and prevent gradual, unhealthy weight gain inadulthood: Engage in approximately 60 minutes of moderate- to vigorous-intensity activity on most days of the week while not exceeding caloric intake requirements. • To sustain weight loss in adulthood: • Participate in at least 60 to 90 minutes of daily moderate- to vigorous-intensity physical activity while not exceeding caloric intake requirements. (Some may need to contact their healthcare provider before participating in this level of activity.) Dietary Guidelines for Americans
How Much Physical Activity a Day? • Any activity helps. • Moderate physical activity brings health benefits. • Make it personal. • Start slowly (10 minute walk/day).

Physical ActivityPrimary Effects on Diabetes Mellitus • Aerobic and resistance types of exercise decrease the incidence of type 2 diabetes. • A modest weight loss through diet and exercise reduces the incidence of diabetes. CMAJ. 2006;174(6): 801-809.
Physical ActivitySecondary Effects on Diabetes Mellitus • Exercise helps in the management of diabetes. • Aerobic and resistance training help in the control of diabetes CMAJ. 2006;174(6): 801-809.
Physical ActivityPrimary Effects on Cancer • Routine activity reduces the incidence cancers. • Activity results in a 30-40% reduction in the relative risk of colon cancer and breast cancer. Moderate physical activity is believed to exhibit a greater protective effect than activities of less intensity. CMAJ. 2006;174(6): 801-809.
Physical ActivitySecondary Effects on Cancer • Regular physical activity - important. • Increased self-reported physical activity = decreased reoccurrence of cancer and a decreased risk of death from cancer. • Reduced cancer-related death. CMAJ. 2006;174(6): 801-809.
Physical ActivityPrimary Effects on Osteoporosis • Many studies have been conducted. • According to findings, routine physical activity, especially weight-bearing and impact exercise, prevents bone loss associated with aging. CMAJ. 2006;174(6): 801-809.
Physical ActivitySecondary Effects on Osteoporosis • Regular physical activity can lead to stronger bones. • Bone responds to physical stress at any age; even in the elderly. Osteoporosis CMAJ. 2006;174(6): 801-809.
The Critical Role of Healthy Eating • Good nutrition leads to a healthier life. • Many do not eat based on MyPyramid recommendations. CDC

Goals for Weight Management of Weight Lost Weight loss:
Calorie DeficitNeeded For Weight Loss • A calorie deficit of no more than 500 kcal/day. • This can be achievable through the combination of diet + exercise. • An example of how to create a calorie deficit of 500 kcal/day through diet + exercise would be: eating 250 kcal less per day, along with burning 250 calories through exercise ACS
Calorie DeficitNeeded For Weight Loss • Eating 250 kcal less per day: • Leave out mayonnaise in a sandwich • Leave out dessert • Switch from soft drinks to water • Reduce portion sizes • burning 250 calories through exercise: • Walk for 30 minutes • Swimming 25 yards • Bicycling for 30 minutes A caloric deficit of 500 can be done by:
Exercise + DietingCalorie Deficit • Initially physical activity, in combination with dieting, is an important component of weight loss. • However, after around 6 months, physical activity will not lead to substantially greater weight losses when combined with dieting. • The benefit of sustained physical activity thereafter is mainly through its role in the prevention of weight gain. • In addition, it has a benefit in reducing cardiovascular and diabetes risks beyond that produced by weight gain alone. NHLBI
Goals for Weight LossAnd Management • The initial goal of weight loss therapy is to reduce body weight by approximately 10 percent from baseline. Once this goal is achieved, then further weight loss can be attempted, if necessary. • A reasonable time line for a 10 percent reduction in body weight is 6 months. • Experience reveals that lost weight is usually regained unless a weight maintenance program, consisting of diet therapy, physical activity and behavior therapy, is continued indefinitely. NHLBI
Goals for Weight LossAnd Management • For overweight individuals with BMIs in the typical range of 27 to 35 kg/m2, a decrease of 300 to 500 kcal/day will result in weight losses of about ½ to 1 lb per week. • A 10 percent weight loss could be achieved within 6 months. • For more severely obese individuals (BMI > 35), deficits of up to 500 to 1,000 kcal/day will lead to weight losses of about 1 to 2 lb per week. • A 10 percent weight loss could be achieved within 6 months.
