Physical activity prevents weight gain over time, but the specific dose-response relationship for weight loss and body composition changes is unclear or less strong compared to mortality benefits.
Use physical activity to prevent weight gain over time, but do not rely on it alone for significant weight loss. The dose-response for long-term weight loss is unclear, and combining exercise with dietary changes is likely necessary for body composition improvements.
ModerateQualifiesMEDIUM confidence
The Panel found some merit for the hypothesis that physical activity is associated with the prevention of weight gain over time, but due to the observational nature of the data, the dose-response question remains unclear (Category C).
Why this rating
Category C evidence (observational) for dose-response; Category A for short-term weight loss.
