The Claim
In children and adolescents with overweight or obesity, face-to-face, family-engaged combined diet and physical activity interventions result in the most consistent improvements in BMI and BMI-z scores at 6 months, with effects typically attenuating within 6–12 months after program cessation in the absence of maintenance support.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In children and adolescents with overweight or obesity, structured programs that involve families and combine diet and physical activity lead to the most consistent reductions in BMI and BMI-z scores at 6 months, but these reductions decrease within 6 to 12 months after the program ends if no ongoing support is provided.
See the scientific wording
In children and adolescents with overweight or obesity, face-to-face, family-engaged combined diet and physical activity interventions produce the most consistent improvements in BMI and BMI-z scores at 6 months, but effects typically attenuate within 6–12 months after program cessation without maintenance support.
When children stop eating healthier and moving more, their bodies burn less energy and store more fat, causing weight to go back up.
What the research says
1 studyWhen kids with extra weight join programs that help them eat better and move more, with their families involved, their weight improves after six months—but if the program stops and no one keeps helping them, the improvement usually goes away within a year. The study confirms this pattern.
