Body Mass Index
How is BMI calculated?
Weight (kg) / (Height (m))^2.
What is the normal range for BMI indicating a healthy weight?
18.5 to 24.9
What is the role of body water in the human body?
Regulates temperature and aids in digestion
What is the primary source of energy for the brain?
Glucose
What does BMR stand for, and what does it represent?
Basal Metabolic Rate; the energy expended at rest
Define visceral fat and its association with health risks
Fat stored around internal organs; linked to increased risk of chronic diseases
How is body fat percentage calculated?
(Fat Mass / Total Body Mass) x 100.
What is the purpose of skeletal muscle in the body?
Supports movement and provides structural support
Which dietary component is essential for the synthesis of collagen, a crucial protein for skin, bones, and connective tissues?
Vitamin C
What is considered a healthy body fat percentage for women?
21-33%
Explain the significance of subcutaneous fat and its distribution in the body.
Fat stored beneath the skin; distribution can affect appearance and health.
What is the role of protein in the body's composition?
Essential for muscle repair, growth, and overall body function.
Define bone mass and its importance for overall health.
The amount of bone tissue in the body; crucial for skeletal strength and preventing osteoporosis.
What is the importance of the circadian rhythm in regulating metabolism?
It controls the sleep-wake cycle and metabolic processes
What factors influence metabolic age?
Diet, exercise, lifestyle; reflects how well the body is functioning compared to chronological age.
How does metabolic age differ from chronological age?
Metabolic age reflects the body's health and efficiency compared to chronological age.
Discuss the impact of excess visceral fat on metabolic health.
Increases the risk of insulin resistance, cardiovascular diseases, and metabolic syndrome.
Explain the concept of body composition and its relevance to health.
Analyzes the proportion of fat and non-fat mass; linked to overall health and fitness.
How does regular physical exercise impact insulin sensitivity?
Insulin sensitivity is increased, so your muscle cells are better able to use any available insulin to take up glucose during and after activity.
How can resistance training influence skeletal muscle mass?
Promotes muscle hypertrophy and increases overall muscle mass.
What role does body water play in weight management?
Adequate hydration can support metabolism and contribute to weight loss.
Explain the concept of metabolic flexibility in relation to body composition.
The ability of the body to efficiently switch between using carbohydrates and fats for energy, influencing weight and health.
What is "thermic effect of food" in relation to metabolism?
The thermic effect of food refers to the energy expended during digestion, absorption, and metabolism of nutrients. It contributes to overall energy expenditure and varies based on the types of foods consumed.
What is the function of the hormone cortisol in the body's response to stress, and how can it impact weight?
Cortisol triggers the "fight or flight" response and decreases metabolism.
