o approx. 300,000 deaths/yearo Obesity equals smoking as cause of preventable deatho Shortens life span 5 -22 years

• Extremely obese white male 20-30 o Lose 13 yrs of lifeo Mortality 12x higher if BMI >40

ObesityObesity• Greatest US health expenditure• Social and ethnic differences in obesity

o Greater in women x 2o Greater among Black Americans

• Women>> meno Greater among non-HS gradso Largest increase in ages 19-28

• 75% of those with extreme obesity have a co-morbid disease

Risk Factors for Risk Factors for ObesityObesity

child’s weighto If 1 parent is obese child’s risk x3o If both obese odds ratio 10

• 10% chance normal weight

Risk Factors for Risk Factors for ObesityObesity

• Environmental Factorso Portion size (market portions are 2-8 times larger than

recommended USDA and FDA recs)o Sweetened beverages

• Increasing since 1970o Socioeconomic status inversely related to obesityo Energy density and food cost inversely relatedo Increase in sedentary leisure time

• 26% watch more than 4 hours of TV time per day• 67% watch more than 2 hours

• Nothing –he is here for knee pain• Recommend that he start a new diet• Refer him to medical nutrition therapy• Not address it today but get more labs and bring

him back• Start him on a medication• Refer him for weight loss surgery

Diabetes PreventionDiabetes Prevention

Lifestyle Lifestyle RecommendationsRecommendations

• Reduce total caloric intake• Increase physical activity• Stop sweetened beverages

• What are the specifics and how do you decide which he does?

• What is the motivation to make all of these changes?

Setting Goals for Weight Loss

• Set reasonable goalso 10% weight loss for first 6 monthso 500-1000 calories less/dayo Decrease 1-2 lb/weeko Most patients set goals 2-3 x higher

• Physical activity is importanto More effective in maintaining weight than weight loss

• Resetting goals and diet/exercise is necessary at 6 months and plateaus in weight loss

• Preventing weight gain is an important long-term goal

SummarySummary• Obesity and type 2 diabetes are intimately

related• Treating obesity can prevent diabetes• Diabetes treatments should be selected with

effects on weight in mind• Aggressive management of weight is important

even once diagnosed with type 2 diabetes• Insulin while necessary in type 1 DM can

contribute to insulin resistance
