energy + nutrient density and BMR + energy expenditure

Question 1

what is BMR?

Answer 1

the basal metabolic rate is the rate at which the body uses energy whilst at rest in order to keep vital bodily functions going. Many different factors can affect BMR< including

• age
• genetics
• gender
• physical activity
• hormones

Question 2

what is the difference between energy and nutrient density?

Answer 2

nutrient density (grams/kJ) is a measure of the amount of nutrients are food supplies per kilojoules, whereas energy density (kJ/grams) is the amount of kilojoules are food provides per gram.

Question 3

what is the amdr? and what does it suggest about the consumption of macronutrients?

Answer 3

the AMDR is the acceptable macronutrient distribution ranges.

• Lipids are 20-35% of daily energy intake
• Carbohydrates are 45-65% of daily energy intake
• Protein - between 15-25% of daily energy intake

Question 4

how do you calculate the percentage energy distribution?

Answer 4

energy provided by macronutrients/total energy in food multiplied by 100.
