In order to reverse the condition, multiple changes must be made. Some involve intense lifestyle change for the individual, which require readiness for change and dedication to maintaining those changes. Some factors affecting obesity can be improved by changing policy and the environment. School and work environments can offer and market healthful foods or fall into the trap of promoting items that are high in fat, sugar and calories. Policy can establish criteria for healthy foods for shared events such as birthday parties, instead of accepting the traditional cakes and pastries.
Few jobs offer the opportunity for physical activity during the workday.
Sitting at a desk all day is truly a health hazard. It is hard to balance sleeping and sedentary time with enough physical activity unless every opportunity for activity during the workday is maximized. Take the stairs instead of the elevator. Even if there is no reason to take the stairs other than for the exercise, it can make a significant contribution to health. Many people can choose to walk to work from a distant parking lot rather than catch a ride to the door.
