Question 1

Harris- Benedict equation calculates RMR based on gender, age, height, weight, and lean body mass and applies an activity factor to determine total daily energy expenditure.

Accepted Answer

The Harris-Benedict equation calculates Resting Metabolic Rate (RMR) based on gender, age, height, and weight, but it does not directly factor in lean body mass. It estimates the total daily energy expenditure by applying an activity factor to the RMR.

Question 2

To determine energy balance, track the number of kilocalories you consume in one day, and add it with the estimated number of kilocalories you expend.

Accepted Answer

To determine energy balance, you should subtract the estimated number of kilocalories you expend from the number of kilocalories you consume in one day, not add them.

Question 3

As the quantity of body fat increases, so does the risk of chronic diseases.

Accepted Answer

Increased body fat is associated with a higher risk of chronic diseases such as type 2 diabetes, heart disease, high blood pressure, and certain cancers.

Question 4

Essential fat is either subcutaneous or visceral fat.

Accepted Answer

The answer of Essential fat is either subcutaneous or visceral...

Question 5

As the quantity of body fat increases, so does the risk of acute diseases.

Accepted Answer

Increased body fat primarily raises the risk of chronic diseases, such as heart disease, type 2 diabetes, and certain cancers, rather than acute diseases.

Question 6

Hydrostatic weighing, air displacement plethysmography, dual- energy X- ray absorptiometry (DEXA), bioelectrical impedance analysis (BIA), and skinfold measurements are all techniques used to determine the percent of lean body mass or body fat.

Accepted Answer

These methods are all used to assess body composition, including the percentage of body fat and lean body mass. Each technique varies in its approach and accuracy, but they are all designed to help estimate the distribution of fat and lean tissue in the body.

Question 7

Measuring waist circumference can determine whether an individual has excess abdominal (central) fat.

Accepted Answer

Measuring waist circumference is a simple and effective way to assess an individual's amount of abdominal (central) fat, which is a key indicator of health risks associated with obesity.

Question 8

Hydrostatic weighing, air displacement plethysmography, dual- energy X- ray absorptiometry (DEXA), bioelectrical impedance analysis (BIA), and skinfold measurements are all techniques used to determine body composition.

Accepted Answer

These methods are commonly used to assess body composition, each utilizing different principles to estimate body fat percentage, lean muscle mass, and other components of body composition.

Question 9

Measuring waist circumference can determine whether an individual has excess LBM.

Accepted Answer

Waist circumference is used to assess abdominal fat, not lean body mass (LBM).

Question 10

Android and apple- shaped fat deposition are synonymous.

Accepted Answer

The answer of Android and apple- shaped fat deposition are...

Question 11

Gynoid "pear- shaped"
fat distribution is common among women.

Accepted Answer

Gynoid fat distribution, often referred to as "pear-shaped," is characterized by fat storage primarily in the lower body (hips, buttocks, and thighs) and is more common among women than men.

Question 12

Men are at higher risk of chronic diseases compared to women.

Accepted Answer

Men are more likely to engage in risky behaviors, such as smoking, drinking alcohol, and not exercising, which can lead to chronic diseases.

Question 13

The body mass index (BMI) is a calculation of the ratio of weight to height and can be used to assess overall health risks.

Accepted Answer

BMI is a widely used measure to assess whether a person has a healthy body weight for a given height, and it helps to categorize individuals into different weight status categories, such as underweight, normal weight, overweight, and obese, which can be indicative of their health risks.

Question 14

Height and weight tables and BMI are used to screen for overweight and obesity.

Accepted Answer

Height and weight tables and BMI (Body Mass Index) are commonly used tools to screen for overweight and obesity by comparing an individual's weight relative to their height.

Question 15

The higher an individual's BMI, the lower their health risks.

Accepted Answer

A higher BMI is generally associated with increased health risks, such as heart disease, diabetes, and certain cancers.
