Figure 2. Patterns of weight loss and regain in children and adults. A. On average, adults will lose weight for only about 6-9 months during lifestyle intervention to treat obesity. After this, most will then begin to regain weight (283-286). B. In contrast, children tend to lose more fatness (expressed as BMI z-score) and sustain their weight loss longer following a lifestyle intervention (61,62). This is especially true for younger children. *Based on DeJonge et al (286). †Based on Kraschnewski et al (16).
