    Study Notes

    Understanding Body Weight and Weight Management

    • Healthy body fat percentages for males and females vary: 13-21% for men and 23-31% for women.
    • Waist circumference can assess android obesity, indicating extra fat in the abdominal area, which increases disease risk.
    • Males are more likely to have an "apple" shape (central obesity) while females are more likely to have a "pear" shape (lower body obesity).
    • Energy balance dictates that if energy intake equals energy expenditure, a person should maintain their body weight.
    • The four components of energy output are basal metabolism, physical activity, thermic effect of food, and non-exercise activity thermogenesis.
    • Basal metabolic rate (BMR) is the minimum energy the body uses for vital activities at complete rest.
    • Factors increasing BMR include growth, very low-calorie diets, exercise, and stimulant drugs, while aging and insufficient thyroid hormone decrease BMR.
    • BMR can be calculated using specific formulas based on gender and body weight.
    • Factors influencing energy expenditure during physical activity include the type, duration, intensity, and the person's weight.
    • The thermic effect of food contributes to 5-10% of total energy output and refers to the energy required to digest, absorb, and metabolize nutrients.
    • NEAT (non-exercise activity thermogenesis) includes involuntary skeletal muscle activities like fidgeting, shivering, and body posture.
    • Factors influencing body weight include internal factors (genes, hormones), individual factors (food, psychology, exercise, stress), community factors (supports, beliefs), local factors (food economy, health systems), and global factors (chemical waste, global food economy).
