Obesity is a chronic disease and a risk factor for diabetes and coronary artery disease, the cause of heart attacks. That, after smoking, obesity is the second most preventable cause of death in the United States. The most successful weight loss program combines calorie reduction, increased physical activity, and when appropriate, behavior therapy to improve eating and exercise habits.
Obesity is more prevalent in some minority populations than among white Americans. These groups include African Americans, especially women, Mexican and Puerto-Rican Americans, some other Hispanic populations, many Native American groups, and those of Pacific Island ancestry.
Americans are consuming about 300 more calories per day than in years past. Part of the problem is that more of us are eating out more often, and portion sizes are larger. Low fat products are everywhere, and many people believe that low fat is healthy and therefore can be consumed freely without regard to quantity. Many Americans ignore calories and fail to get enough exercise.
Another possible cause for the increase in obesity is Americans' obsession with fat in the diet and attempting to eliminate or reduce it by overeating low fat foods. However, many low-fat foods are actually higher in calories than regular fat versions. It is still important to read food labels and compare products, because although fat matters, calories count.
Physical activity counts too. Most Americans do not get enough physical activity. Instead we spend too much time sitting at our computers, driving the car, watching television, and taking the elevator instead of the stairs. All Americans should get at least 30 minutes of moderate exercise, such as brisk walking or biking on most, if not all, days of the week.
By sticking with the basics, weight loss and maintenance can be achieved by adding a few changes to your lifestyle.
