Inactivity is one of the biggest reasons for obesity in children. Berkey et al., conducted a study on 11,887 children from the ages of 10–15 to test whether or not an increase in a person's activity level would reduce a person's body fat. A test done on girls concluded that an increase in physical activity brought their body mass index (BMI) down .11. The male test resulted in a .33 decrease in their BMI. An increase of inactivity showed an increase in BMI for girls by .02. A way to improve this inactivity would be by changing a child's daily physical regime. Switching an overweight child's daily physical activity could help a child lose weight and get into better physical condition. Rodearmel et al., studied a couple of Latino families who had at least one child between the ages of 7–14. This was done over a 6-month span. There were two groups that the children were put into. The first group was the "America on the Move" group and the other group was the "self monitor only" group. The America on the Move group had to walk an additional 2,000 steps per day from their baseline which was already measured through pedometers and to eliminate 100 kcal/day from their normal diet by replacing dietary sugar with no caloric sweetener. The self monitor group did not have to change their physical activity or their diet. This group only had to record their physical activity with pedometers. Both groups had results showing they had decreased their BMIs with the America on the Move group decreasing their BMI much more significantly.
