Obesity is arguably the leading challenge among the epidemic facing the world because it is on the rise in both developing and developed countries. When we talk about “global issues,” it usually has to do with trade or the environment. But there is another area where global trends are apparent: the whole world is getting fatter! This tendency is maligned in a city chairman risk of a number of diseases.
The prevalence rates of obesity have increased dramatically in the last decade and are expected to double in the next 25 years. In almost epidemic proportions now, obesity is the starting point for many diseases including diabetes, heart disease, hypertension, and even some forms of cancer. It is the plague of the real society.

What is obesity?
Obesity is a condition of excess body fat. It can be defined as being more than 20% above the normal ideal weight for sex, age and weight. To say that simply consuming too many calories causes obesity is like saying that the only cause of the Yankee Folklore Revolution was the Boston Casual get-together. It’s important to note that no “weight loss diet or formula” works independently of an eating plan based on the Dietary Guidelines provided by the leading institutes of health and nutrition. So if you’re obese throw out all those “special formulas” supplements and pills, stop eating more calories than you need and try to become more physically active and adopt a healthy eating plan.
Obesity is the net result of an excess of energy intake over expenditure. Factors that should be considered as contributing to child causation: heredity, overeating, impaired metabolism of adipose tissue, defective or decreased thermogenesis (the process by which calories are converted to heat), decreased physical activity without a adequate reduction in food intake and certain prescription drugs.
Overeating is clearly a major contributor to obesity. It’s a very complex problem with one adoptable solution, which is to make physical activity a part of your daily life, it’s an important way to help control your weight and decrease the risk of health problems.
To lose weight, one must decrease caloric intake, increase caloric expenditure, or do both. Therefore, the main approaches to weight reduction involve behavior change related to diet and exercise. Weight loss decreases health risks in the obese. Because obesity is a condition that requires ongoing care, any behavior changes required to maintain weight loss must be lifelong.

Benefits of physical activity:
Physical activity contributes to weight loss, especially when combined with calorie reduction. Customary physical activity is of great help for the prevention of overweight and obesity.
Being physically active can provide these benefits:
Lessen the risk of dying from heart disease or stroke
Decreases high blood vessel pressure
Helps keep your bones, muscles and joints healthy
Lessen anxiety and depression and improves mood
Helps you manage stress
Helps control weight
Protects against falls and bone fractures in older adults
May help protect against breast cancer
Helps control joint inflammation and arthritis pain
Gives you more energy
Helps you sleep better
Helps you look better
Regular physical activity, fitness and exercise are imperative to the health and well-being of people of all ages. Spend less time on low-energy activities like watching TV and playing video games and more time on physical activities. Being physically active does not force you to spend hours in the gym. It can also get by with activities one enjoys like: pushing a stroller, gardening, climbing stairs, walking, dancing, and biking, to name a few.
Create opportunities for activity, such as parking your car farther away, taking the stairs instead of the elevator, or walking down the hall to talk to a coworker instead of email. Don’t let the cold keep you on the sofa! You can still find activities to do in the winter, like working out with a fitness video or joining a sports league. Or get a head start on your spring cleaning by choosing active inside tasks like washing windows or rearranging closets.

How should the exercise start?
In general, physical activity should start slowly and the intensity should increase
gradually (for example, start with a 10-minute walk three times a week and build up to 30 minutes of brisk walking or another form of moderate activity five times a week). Activities can be divided into several short periods (eg, 10 minutes 3 times a day) instead of one longer period (eg, 30 minutes once a day).
The other major risk factor for obesity, besides lack of physical activity, is balancing energy intake and energy expenditure.
To maintain your weight, your calorie intake must equal your energy output. Comparably, to lose weight, you must use more energy than you take in.
Restrictions alone don’t usually work for long-term weight control. It can only be possible by becoming more active, which will help burn extra calories and also help reduce abdominal obesity. Therefore, a proper diet and physical activity will help to achieve a healthy and happy life.
Therefore, one should select activities that they ENJOY and that fit into daily life. It may take time to get more activity into your daily life. Don’t be discouraged if you miss a day or two at first; just keep trying and do your best to make it a regular part of your life. Then, one will soon realize how good it feels to be physically active and fit.
