Study Notes
Daily Caloric Needs
- Daily energy requirements differ by gender: Men require approximately 24 calories per kg of body weight, while women need about 22 calories per kg.
Basal Metabolic Rate (BMR)
- BMR is influenced by body composition; more lean tissue results in a higher BMR.
- Generally, men have a greater lean body mass than women, leading to a higher BMR for men.
- Fever increases BMR due to heightened metabolic demands.
Physical Activity Impact
- Caloric expenditure during physical activity is determined by duration, frequency, and intensity of the activity.
- Duration refers to the length of time spent exercising.
- Frequency indicates how often one engages in physical activity.
Mental Health and Body Image Issues
- Distorted body image occurs when individuals perceive themselves as overweight despite being underweight.
- Intense fear of weight gain can persist even in those who are underweight, often leading to restrictive eating habits.
- Obsessive behaviors related to food, such as calorie counting and meal skipping, are common.
- Excessive exercise is often employed as a strategy for weight loss, potentially leading to health risks.
Basal Metabolism Rate (BMR)
- Represents the amount of energy expended by the body at rest to maintain basic physiological functions.
Thermogenesis
- Refers to the energy used in the process of digesting food.
- Important aspect of total energy expenditure, accounting for energy used in processing meals.
Total Energy Expenditure
- The total energy expenditure includes BMR, the energy used in thermogenesis, and energy spent during physical activity.
Body Fat Distribution and Health
- The location of body fat affects health risks associated with obesity.
- Health risks are assessed using the waist-to-hip ratio, calculated by dividing waist measurement by hip measurement.
- A higher waist-to-hip ratio indicates greater health risks linked to obesity.
Thermic Effect of Food (TEF)
- The thermic effect of food is the energy required for digestion, absorption, and metabolism of nutrients.
- Influenced by the frequency of food consumption; more frequent meals can elevate TEF.
Body Image and Mental Health
- Distorted body image can cause individuals to perceive themselves as overweight despite being underweight.
- An intense fear of gaining weight can lead to unhealthy behaviors and psychological distress, often seen in eating disorders.
Body Composition and Metabolism
- Visceral fat is associated with individuals who have a Body Mass Index (BMI) of 25 or higher.
- Stress hormones can elevate Basal Metabolic Rate (BMR), increasing energy expenditure.
- Environmental temperature changes, such as exposure to heat or cold, can also increase BMR.
Effects of Nutritional States
- Fasting and starvation conditions lead to hormonal changes that decrease BMR.
- Malnutrition is linked to a reduction in BMR, affecting overall energy expenditure.
Thermogenesis and Energy Expenditure
- The thermic effect of food contributes to 5-10% of daily energy expenditure.
- Approximately 10% of consumed calories are utilized for digestion and metabolism during food processing.
Eating Disorders
- Distorted body image can manifest as perceiving oneself as overweight despite being underweight.
- An intense fear of weight gain persists even in underweight individuals.
- Restricted eating patterns can involve limiting food intake severely or avoiding certain food groups.
- Obsessive food behaviors include counting calories, skipping meals, or concealing food.
- Excessive exercise is often utilized as a method to facilitate weight loss.
Body Shapes and Health Risk
- Apple-shaped individuals are more prone to obesity-related health issues compared to pear-shaped individuals.
- Apple-shaped body type is associated with visceral fat accumulation, which increases the risk for metabolic diseases.
Basal Metabolism Rate (BMR)
- BMR is the energy expended by the body at rest to maintain vital functions such as breathing and circulation.
- It reflects the energy required over a 24-hour period when the body is in a fully rested state, without digestive activity or physical effort, and at room temperature.
Factors Affecting BMR
- Age impacts BMR, generally resulting in higher rates in youth; BMR decreases as lean body mass declines with age.
Thermogenesis and the Thermic Effect of Food
- The thermic effect of food contributes to 5-10% of daily energy expenditure.
- Approximately 10% of total caloric intake is utilized for digestion and processing food.
- Meal size and composition, especially high-protein foods, can influence the thermic effect.
Physical Activity's Role in Energy Expenditure
- Physical activity accounts for 15-30% of daily energy expenditure.
- Engaging in higher levels of physical activity increases overall calorie burn, while inactivity decreases it.
