Study Notes
Managing Your Weight
Factors Influencing Weight
- Genetics play a role in obesity, but it's not the only factor
- Environmental factors:
- Food intake: types and amounts of food consumed
- Energy density: calories per volume of food
- Satiety: feeling of fullness after eating
- Physical activity: amount of activity each day
- Sedentary lifestyle: little physical activity
- Psychological factors:
- Stress: can lead to overeating and weight gain
- Emotional eating: eating in response to negative emotions
- Body image: perception of one's own body
- Weight loss and maintenance: calorie restriction, low-calorie diet, very-low-calorie diet (VLCD), behavior modification, self-monitoring, goal setting, social support
Energy Balance and Weight
- Energy balance: relationship between energy intake and expenditure
- If energy intake = energy expenditure, weight stays the same
- If energy intake > energy expenditure, weight gain occurs
- If energy intake < energy expenditure, weight loss occurs
- Basal metabolic rate (BMR): energy body uses for basic physiological processes
- Metabolism: sum of all chemical reactions in the body
- Physical activity: any movement that uses energy
Body Composition
- Relative amounts of lean body mass and fat in the body
- Body-fat distribution: important for health
- Measuring body composition: skinfold calipers, bioelectrical impedance analysis (BIA), underwater weighing
Body Mass Index (BMI)
- Tool for assessing weight status
- Calculated by dividing weight in pounds by height in inches squared
- BMI values interpreted differently for children, teens, and adults
- Imperfect tool, as muscles may have a high BMI
