Obesity is still a problem in society

Obesity means having too much body fat. It is different from being overweight, which means weighing too much. The weight may come from muscle, bone, fat and/or body water. Both terms mean that a person's weight is greater than what's considered healthy for his or her height.
Obesity occurs over time when you eat more calories than you use. The balance between calories-in and calories-out differs for each person. Factors that might tip the balance include your genetic makeup, overeating, eating high-fat foods and not being physically active.
Being obese increases your risk of diabetes, heart disease, stroke, arthritis and some cancers. If you are obese, losing even 5 to 10 percent of your weight can delay or prevent some of these diseases.
Reasons why obesity is still a problem include?
1. Changes to our diets
Multiple lifestyle changes were independently associated with long-term weight gain, including changes in the consumption of specific foods and beverages, physical activity, alcohol use, television watching, and smoking habits. Strong positive associations with weight change were seen for starches, refined grains, and processed foods. Some foods ?vegetables, nuts, fruits, and whole grains ?were associated with less weight gain when consumption was actually increased. Obviously, such foods provide calories and cannot violate thermodynamic laws. Their inverse associations with weight gain suggest that the increase in their consumption reduced the intake of other foods to a greater (caloric) extent, decreasing the overall amount of energy consumed. Yogurt consumption was also associated with less weight gain in all three cohorts. What needs to happen? We need to start eating healthy diets again. We need to consume more fresh, locally grown fruits and veggies. We need to cook in the home, where we have control over the calorie, fat and sugar content of our diets. Communities need to make access to local markets readily available as well as cost-effective for lower-income families. Eating unhealthy diets shouldn抰 be cheaper than diets that contain healthy food options.
2.Physical activity卭r lack there of
There抯 increasing evidence that our sedentary lives are putting millions of us at increased risk of health problems and even early death. The link between inactivity and obesity and poorer health generally identified in is illuminating but scarcely surprising. In our increasingly technological age, even moderately strenuous physical activity is something most of us don抰 experience on a daily basis. The average child of today now watches between three to four hours of television daily ?and spends additional hours on the Internet. Meanwhile, walking and cycling have been replaced by automobile travel for all but the shortest distances, and for adults, the workplace has become increasingly automated as well.
That抯 the problem. But it does have a solution ?creating home, work and school environments that promote regular physical activity. It won抰 be easy, but then, nothing important ever is.
3. Yo-Yo dieting
Yo-yo diet resulted in large fluctuations in these health measures, decreasing during the low-fat diet and increasing to a diabetic state during the high-fat diet. When health measures during the high fat and low-fat diet regimens of the yo-yo diet group were averaged, their "average health" was improved compared with obese mice that stayed on the high-fat diet.
. What needs to happen? We need to stop 揹ieting?to lose weight and implement healthy changes to our diets. This includes adopting a lifestyle change which includes healthy foods all of the time in addition to physical activity. While these changes may be difficult in the beginning, they will get easier with time. In the long run, healthy lifestyle changes will lead to weight loss and an overall improvement in your health.
