    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.
