A number of popular programs exist including Weight Watchers, Overeaters Anonymous and Jenny Craig. These appear to provide modest weight loss (2.9kg) over dieting on one's own (0.2kg) over a two-year period, similarly to non-commercial diets. As of 2005, there was insufficient scientific evidence to determine whether Internet-based programs produce effective weight loss. The Chinese government has introduced a number of "fat farms" where obese children go for reinforced exercise and has passed a law which requires students to exercise or play sports for an hour a day at school (see Obesity in China).
