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 PreventionTrusted Source (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, defined as having a body mass index (BMI) of 30 or higher. Body mass is derived by dividing weight in pounds by height in inches squared, and then multiplying the result by 703 (weight (lb) / [height (in)] 2 x 703). You can calculate your body mass by following these three steps:
Multiply your weight in pounds by 703.
Calculate your height in inches squared.
Divide the resulting number from step 1 by the resulting number in step 3.
Obesity can lead to a number of serious health problems, including heart disease, diabetes, stroke, and some types of cancer.
One method that can help a person lose weight is to limit the number of calories taken in through their diet. The other way is to burn extra calories with exercise.
Benefits of Exercise vs. Diet
Combining exercise with a healthy diet is a more effective way to lose weight than depending on calorie restriction 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.
Exercise is helpful for weight loss and maintaining weight loss. Exercise can increase metabolism, or how many calories you burn in a day. It can also help you maintain and increase lean body mass, which also helps increase number of calories you burn each day.
How Much Exercise Is Needed for Weight Loss?
To reap the health benefits of exercise, it is recommended that you 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 can equals 10 lbs. of weight loss over the course of a year.
