Chapter 7: Q.24CQ (page 259)

Discuss the relative effectiveness of dieting and exercise in losing weight, noting that most athletic activities consume food energy at a rate of 400 to 500 W, while a single cup of yogurt can contain 1360 kJ (325 kcal). Specifically, is it likely that exercise alone will be sufficient to lose weight? You may wish to consider that regular exercise may increase the metabolic rate, whereas protracted dieting may reduce it.

Short Answer

Expert verified

Dieting and exercise both are weight-losing processes, but exercise is more effective as it increases the metabolism rate, which helps in burning the body’s fat.

Step by step solution

01

Definition of Concepts

Dieting and exercise:Both dieting and exercise are weight loss processes. The difference between dieting and exercise is that in dieting body uses the stored energy of the body to sustain the life process, whereas in exercise, the metabolism rate of the body increases which helps in burning the stored fat.

02

Explain the relative effectiveness of dieting and exercise in losing weight

Alone exercise will not be effective because if you consume more fat then the fat will keep on storing in the body, irrespective of a higher metabolism rate.

Therefore, in process of losing weight both exercise and dieting are important.

Most popular questions from this chapter

Consider a person climbing and descending stairs. Construct a problem in which you calculate the long-term rate at which stairs can be climbed considering the mass of the person, his ability to generate power with his legs, and the height of a single stair step. Also consider why the same person can descend stairs at a faster rate for a nearly unlimited time in spite of the fact that very similar forces are exerted going down as going up. (This points to a fundamentally different process for descending versus climbing stairs.)

A shopper pushes a grocery cart 20.0 m at constant speed on level ground, against a 35.0 N frictional force. He pushes in a direction 25.0º below the horizontal.

(a) What is the work done on the cart by friction?

(b) What is the work done on the cart by the gravitational force?

(c) What is the work done on the cart by the shopper?

(d) Find the force the shopper exerts, using energy considerations.

(e) What is the total work done on the cart?

The Crab Nebula (see Figure 7.41) pulsar is the remnant of a supernova that occurred in A.D. 1054. Using data from Table 7.3, calculate the approximate factor by which the power output of this astronomical object has declined since its explosion.

Describe the energy transfers and transformations for a javelin, starting from the point at which an athlete picks up the javelin and ending when the javelin is stuck into the ground after being thrown.

Calculate the power output needed for a 950-kg car to climb a 2.00° slope at a constant 30.0 m/s while encountering wind resistance and friction totaling 600 N. Explicitly show how you follow the steps in the Problem-Solving Strategies for Energy.
