People can be classified being overweight by using the number called body mass index (BMI). BMI correlates with the amount of body fat of people, and it can be calculated by dividing weight in kilograms with height in meter squared . For adults who are classified overweight have a BMI between 25 and 29.9 and those who have BMI of 30 or greater are classified obese . There are many causes leading people to become overweight and obesity in the USA: for example, (1) high-fat food intake such as fast food that contains high sugar and fat is the most organized cause, (2) the absence of physical activity for energy expenditure, and (3) lack of sleep which is associated with weight gain [2, 3]. In the present, there are many adults in the USA who are classified overweight.
