Summary: | Background
Controversy exists regarding the optimal rate of weight loss for long-term weight management success.
Purpose
This study examined whether gradual initial weight loss was associated with greater long-term weight reduction than rapid initial loss.
Methods
Groups were drawn from participants in the TOURS trial, which included a sample of middle-aged (mean = 59.3 years) obese women (mean BMI = 36.8) who received a 6-month lifestyle intervention followed by a 1-year extended care program. Participants were encouraged to reduce caloric intake to achieve weight losses of 0.45 kg/week. Groups were categorized as “FAST” (≥0.68 kg/week,
n
= 69), “MODERATE” (≥0.23 and <0.68 kg/week,
n
= 104), and “SLOW” (<0.23 kg/week,
n
= 89) based on rate of weight loss during first month of treatment.
Results
The FAST, MODERATE, and SLOW groups differed significantly in mean weight changes at 6 months (−13.5, −8.9, and −5.1 kg, respectively,
p
s < 0.001), and the FAST and SLOW groups differed significantly at 18 months (−10.9, −7.1, and −3.7 kg, respectively,
p
s < 0.001). No significant group differences were found in weight regain between 6 and 18 months (2.6, 1.8, and 1.3 kg, respectively,
p
s < 0.9). The FAST and MODERATE groups were 5.1 and 2.7 times more likely to achieve 10% weight losses at 18 months than the SLOW group.
Conclusion
Collectively, findings indicate both short- and long-term advantages to fast initial weight loss. Fast weight losers obtained greater weight reduction and long-term maintenance, and were not more susceptible to weight regain than gradual weight losers. |
