    Study Notes

    Physical Activity

    • Sedentary individuals have a physical activity factor of 1.2
    • Lightly active individuals with light exercise 1-3 days/week have a physical activity factor of 1.375
    • Moderately active individuals with moderate exercise 3-5 days/week have a physical activity factor of 1.55
    • Very active individuals with hard exercise 6-7 days/week have a physical activity factor of 1.725
    • Extra active individuals with very hard exercise and physical job or twice daily training have a physical activity factor of 1.9

    Body Mass Index (BMI)

    • BMI measures weight relative to height
    • BMI is often used to diagnose overweight or obesity.
    • Formula for BMI is weight in kg / (height in meters)²
    • Normal body weight BMI range is 18.5-24.9
    • Overweight BMI range is 25-29.5
    • Obese BMI is over 30
    • Underweight BMI is under 18.5

    BMI and Disease Risk

    • Overweight or obesity increases risk of cardiovascular disease
    • Overweight or obesity increases risk of hypertension
    • Overweight or obesity increases risk of Type 2 diabetes
    • Overweight or obesity increases risk of stroke
    • Overweight or obesity increases risk of gallbladder disease
    • Overweight or obesity increases risk of osteoarthritis
    • Overweight or obesity increases risk of sleep apnea
    • Overweight or obesity increases risk of respiratory problems
    • Overweight or obesity increases risk of endometrial, breast, prostate, and colon cancers

    Calories In: The Food We Eat

    • Fast food and convenience foods can contribute to excess calories through fat and sugar content
    • Foods marketed as low-fat or fat-free can be deceiving as the calories may be equal to or greater than original product
    • Larger portion sizes can contribute to excess calories, especially when dining out

    Calories In: Portion Size Changes Over Time

    • Portion sizes have increased over time, contributing to increased calorie intake

    Calories In: Sugar-Sweetened Beverages

    • Sugar-sweetened beverages (SSBs) are a significant source of added sugar in the diet
    • Adolescents who eliminated SSBs from their diet for a year gained 4 pounds less than their peers who continued to consume SSBs

    Calories Out: Energy Expenditure

    • Individuals vary in the number of calories they burn each day
    • Calories are expended through resting energy expenditure (REE), physical activity and thermic effect of food (TEF)
    • These three components make up total energy expenditure

    Physical Activity

    • Incorporate planned physical activity into daily routine
    • For overall health, aim for 30 minutes of moderate activity, 5 days a week
    • For maximum cardiovascular benefit, aim for vigorous activity for at least 20 minutes per session
    • Exercise for weight loss requires a combination of aerobic activity to burn calories and strength training to build muscle

    Behavior

    • When trying to lose weight, it's important to understand why you eat, not just what you eat
    • Social cues that can trigger eating include family traditions, holiday celebrations, and media influences
    • Emotional cues that can trigger eating include stress and boredom

    Satiety and Hunger

    • The food intake cycle involves satiety (fullness), hunger, satiation (feeling satisfied) and seeking food
    • When you feel full and satisfied, you're more likely to stop eating, and vice versa

    Medications to Treat Obesity

    • Drug therapy is often used as part of weight-loss treatment
    • It is typically recommended for individuals who are extremely obese or have life-threatening health complications
    • Medication is not a permanent solution for weight loss
    • Medications are ineffective without a combination of diet, physical activity, and behavioral modification

    Weight Loss Surgery

    • Weight loss surgery is becoming increasingly popular as a treatment for obesity
    • It’s an option for those who have not been successful with other methods
