The Claim
In mice, weight regain following weight loss is primarily driven by increased food intake rather than reduced energy expenditure, and pair-feeding prevents weight regain despite prior obesity.
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.
After losing weight, mice regain weight mainly because they eat more, not because they burn less energy; when their food intake is controlled to match that of mice that never lost weight, they do not regain weight.
See the scientific wording
In mice, weight regain after weight loss is primarily driven by increased food intake rather than reduced energy expenditure, as pair-feeding prevents weight regain despite prior obesity.
After losing weight, the brain keeps signaling the body to eat more because of lasting changes in hunger circuits, while fat tissue remains resistant to insulin. This forces the body to consume extra calories to manage blood sugar, leading to weight gain even when energy burning stays normal.
What the research says
1 studyWhen overweight mice lose weight but are allowed to eat as much as they want, they gain the weight back. But if they’re fed the same small amount as lean mice, they don’t gain weight—proving it’s eating too much, not burning fewer calories, that causes the regain.
