Chapter 25, Problem 1RAC

Summary Introduction

Introduction:

A calorie is an energy unit. In nutritional terms, calories refer to the energy people get from their food and drink and the energy they use in physical activity.

Expert Solution & Answer

Answer to Problem 1RAC

The correct answer is option (d). A pound of body fat contains 3500 kcal.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d) A pound of body fat contains 3500 kcal. A kilocalorie is an energy unit and is used to describe the energy used by the body. A pound of body fat is equal to 3500 kcal energy. That is why removing 500 kcal per day from the diet help an individual to lose one pound in a week. So, the correct answer is option (d).

Explanation for incorrect answer:

Option (a) A kilocalorie is the amount of energy required to raise the temperature of 1g of water 1° C. A single calorie is energy necessary to raise the temperature of one kilogram by 1-degree Celcius. It is 1000 times more needed to raise the temperature of 1 gram. So, this is an incorrect option.

Option (b) There is 9 kcal in a gram of protein. It has been calculated that 4 kcal of energy is present in one gram of calorie. So, this is an incorrect answer.

Option (c) There is 4 kcal in a gram of lipids. A gram of lipid has 9 kcal of energy, not 4. Therefore, this statement is wrong.
