The Importance of Weight Loss and Exercise
Carrying around too much weight feels uncomfortable and it can also
damage your health. According the Centers of Disease Control and
Prevention (CDC), obesity rates have skyrocketed in the United States
in recent years. As of 2010, more than one-third of American adults
were considered obese with a body mass index (BMI) of over 30 (CDC, 2012).
Obesity can lead to a number of serious health problems including heart disease, diabetes, stroke, and cancer. In the United States, body mass is derived by dividing weight in pounds by height in inches squared and multiplying the result by 703 (weight (lb) / [height (in)] 2 x 703).
One method that can help a person lose weight is to limit the number of calories taken in through the diet. The other way is to burn extra calories with exercise.

Part 2 of 7: Benefits
Benefits of Exercise vs. Diet
Unlike diet alone, exercise can prevent or even reverse the effects
of certain diseases. Exercise lowers blood pressure and cholesterol,
which may prevent a heart attack. In addition, if you exercise, you
lower your risk of developing certain types of cancers such as colon
and breast cancer. Exercise is also known to help contribute to a sense
of confidence and well-being, thus possibly lowering rates of anxiety
and depression.
Part 3 of 7: Exercise
How Much Exercise Is Needed for Weight Loss?
To benefit from exercise, you need to perform some form of aerobic
exercise at least three times a week for a minimum of 20 minutes per
session. However, more than 20 minutes is better if you want to
actually lose weight. Incorporating just 15 minutes of moderate
exercise—such as walking one mile—on a daily basis will burn up to 100
extra calories (assuming you don’t consume excess calories in your diet
afterwards). Burning 700 calories a week equals 10 lbs. of weight loss
over the course of a year.
Part 4 of 7: Heart Rate
Calculating Your Target Heart Rate
To receive all of the health benefits of exercise, you’ll need to
reach and maintain what is known as your “target heart rate.” The basic
formula for determining your target heart rate is to subtract your age
from 220 and then calculate 60 to 80 percent of that number.
(Beginners should start at the 60 percent figure and work their way up to 80.)
Those with special health concerns such as an injury, diabetes, or a heart condition should consult a physician before beginning any fitness program.

Part 5 of 7: Types of Exercise
What Are Some Examples of the Different Types of Exercise?
The type of exercise you choose for weight loss doesn’t matter as
much as whether or not you’re doing it. That’s why experts recommend
you pick exercises you enjoy so that you’ll stick to a regular routine.
Aerobic
No matter what exercise program you implement, it should include some form of aerobic or cardiovascular exercise. Aerobic exercises get your heart rate up and your blood pumping. Aerobic exercises may include walking, jogging, cycling, swimming, and dancing. You can also work out on a fitness machine such as a treadmill, elliptical, or stair stepper.Weight Training
A big advantage of working out with weights is that, in addition to shedding fat, you’ll build muscle. Muscle, in turn, burns calories. Talk about a healthy feedback loop! Experts recommend working all the major muscle groups three times per week. This includes:- abs
- back
- biceps
- calves
- chest
- forearms
- hamstrings
- quads
- shoulders
- traps
- triceps
Yoga
While not as intense as other types of exercise, yoga can help you lose weight in other ways, according to a recent study by researchers at the Fred Hutchinson Cancer Research Center. The study found that people who practice yoga are more mindful about what they eat and, therefore, less likely to be obese.
Part 6 of 7: Lifestyle
Incorporating Exercise into Your Lifestyle
The amount of exercise you engage in matters more than whether or
not you do it in a single session. That’s why small changes in your
daily routine can make a big difference in your waistline.
Healthy lifestyle habits to consider include:
Healthy lifestyle habits to consider include:
- walking or riding your bike to work or while running errands
- taking the stairs instead of the elevator
- parking farther away from destinations and walking the remaining distance
Part 7 of 7: Calories
Activities and the Amount of Calories They Burn
The average adult male who doesn’t exercise requires approximately
2,200 calories a day to maintain his average weight. A female needs
about 1,800 calories to maintain her weight.
The following list contains common activities and the amount of calories burned per hour:
