Obesity is a medical condition of excess body fat accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese.

In the study of examined the long-term effectiveness of behavioral weight controlprograms, conducted by Marshall University School of Medicine(1), researchers found that A 2-year follow-up study was designed to assess the effectiveness of a behavioral weight control program on 123 obese male and 386 obese female subjects. Following an 8-week treatment period, mean weight was 176.4 +/- 41.3 lb (no. = 509), yielding a mean weight loss of 9.2 +/- 6.4 lb. Weight change after the 8-week treatment period ranged from a loss of 37 lb to a gain of 5 lb. The 2-year follow-up study showed that mean weight of the 498 subjects was 179.8 +/- 42.9 lb, yielding a mean weight loss of 5.8 +/- 15.5 lb. Weight change ranged from aloss of 71 lb to a gain of 47 lb. After 2 years, 325 subjects (65.3%) were still below their baseline weights, 182 subjects (36.6% of the entire study group) had maintained or enhanced the weight loss achieved during treatment, and 80 subjects (16.1%) weighed at least 10% less than their baseline weight.
