The Claim
Among obese adults, achieving at least 3% weight loss within the first three months of starting any diet is strongly associated with greater long-term weight loss over five years, regardless of diet type.
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.
Obese adults who lose at least 3% of their body weight in the first three months of dieting tend to lose more weight over five years than those who do not, no matter what diet they follow.
See the scientific wording
Among obese adults, achieving at least 3% weight loss within the first three months of starting any diet is strongly associated with greater long-term weight loss over five years, regardless of diet type.
When a person loses weight quickly at the start of a diet, their body reduces hunger signals and increases fat-burning efficiency, making it easier to keep losing weight over time.
