Energy Balance and Body Composition

Vocabulary flashcards covering key concepts related to energy balance, body composition, and disordered eating.

Energy Balance

The relationship between energy intake and energy expenditure, crucial for maintaining body weight.

Positive Energy Balance

A state where energy intake exceeds energy expenditure, often leading to weight gain.

Negative Energy Balance

A condition when energy intake is less than energy expenditure, resulting in weight loss.

Basal Metabolic Rate (BMR)

The amount of energy expended while at rest to maintain basic physiological functions.

Total Daily Energy Expenditure (TDEE)

The total number of kilocalories needed in a day to meet energy requirements.

Thermic Effect of Food (TEF)

The energy required for digestion, absorption, and metabolism of nutrients.

Adaptive Thermogenesis

The process where the body adjusts its energy expenditure in response to environmental factors.

Body Composition

The proportion of lean body mass and body fat in an individual.

Hydrostatic Weighing

A method used to assess body fat percentage by measuring buoyancy in water.

Body Mass Index (BMI)

A screening tool that uses height and weight to classify individuals as underweight, normal weight, overweight, or obese.

Anorexia Nervosa

A life-threatening eating disorder characterized by self-starvation and excessive weight loss.

Bulimia Nervosa

An eating disorder involving cycles of binge eating followed by purging or compensatory behaviors.

Binge Eating Disorder
