The Claim

In women who have achieved a normal BMI after weight loss, a longer duration to reach the weight-loss goal is associated with a higher likelihood of subsequent weight regain.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Women who take longer to lose weight and reach a normal BMI are more likely to regain the weight later.

See the scientific wording

In women who have lost weight and achieved a normal BMI, the time taken to reach their weight-loss goal is positively associated with subsequent weight regain, suggesting that greater difficulty in losing weight may predict poorer long-term maintenance.

Why this might work

When weight loss takes a long time, the body lowers its energy use and increases hunger signals, making it easier to regain weight once eating returns to normal levels.

  1. Study: Perception of exercise difficulty predicts weight regain in formerly overweight women

    Women who felt their workouts were harder after losing weight were more likely to gain it back within a year — suggesting that if losing weight felt really tough, keeping it off is also likely to be tough.
