 This research suggests that women who have lost weight are at greater metabolic risk for weight regain than those with a similar body mass index, BMI, who have never lost weight. Additionally, women who have previously lost weight show signs of metabolic adaptation, such as decreased fat oxidation and increased thermogenesis, which can make it harder to maintain a healthy weight. This study also found that women who have maintained a healthy weight have better control over their eating habits and physical activity levels than those who have lost weight.
