Can you help me with this question?
The determinant of total energy requirement that may most appropriately
be manipulated in a weight loss program
is:
1. basal matabolic rate
2. physical activity
3. dietary thermogenesis
4. body temperature
Would the correct answer be #2 or #3?
Please help!
dietary thermogenesis cannot be manipulated, can it? It is based on basal metabolism.
Are basal metabolic energy needs determined by involuntary activities?
Of course. Basal = basic, breathing, heart beating, temperature regulation.
i don't know. u said please read this and i did and this is what i'm saying.
good 4 u!!
sure i guess the please read this thing got me too
To determine which option is the correct answer, let's break down each determinant of total energy requirement and see which one can be most appropriately manipulated in a weight loss program.
1. Basal metabolic rate (BMR): This refers to the energy expenditure at rest, which includes activities such as breathing, heart beating, and temperature regulation. BMR is mainly determined by factors such as age, gender, body composition, and genetics. While BMR can vary among individuals, it is not easily manipulated for weight loss purposes.
2. Physical activity: This refers to the energy expended through voluntary activities such as exercise, sports, and movement. Physical activity can be easily manipulated in a weight loss program by increasing the frequency, intensity, or duration of exercise.
3. Dietary thermogenesis: This refers to the energy expended for digesting, absorbing, and metabolizing food. It accounts for approximately 5-10% of total energy expenditure and is influenced by the composition of the diet (e.g., protein-rich foods have a higher thermic effect). While you are correct that dietary thermogenesis cannot be intentionally manipulated, it can still be affected indirectly through dietary choices.
4. Body temperature: While the body's temperature regulation does contribute to energy expenditure, it is not a primary determinant that can be manipulated for weight loss purposes.
Based on these explanations, the correct answer would be #2 - physical activity. Physical activity can be adjusted in a weight loss program to increase energy expenditure and create a calorie deficit, which is essential for weight loss.
