Adherence
Achieving significant weight loss (≥10%) in the first year of a lifestyle intervention is a strong predictor of maintaining that loss at 4 years.
Focus on achieving significant weight loss in the first year, as this is the strongest predictor of long-term success. However, even if you don't lose much initially, staying engaged with the program and adhering to behavioral strategies can still lead to positive outcomes.
WeakSupportsVERY_HIGH confidence
Within the ILI, achievement of both the 5% and 10% categorical weight losses at year 4 was strongly related to meeting these goals at year 1.
Why this rating
Derived from the same large RCT with robust statistical analysis (logistic regression).
