U.S. study by Dr. Nackers and published in Springer's International Journal of Behavioral Medicine confirms that a rapid and significant loss of weight at the beginning of regime allowed a better long-term stabilization.
BACKGROUND AND OBJECTIVES:
There is controversy regarding the optimal rate of weight loss and long-term success in weight management after diet. This study examined whether gradual initial weight loss was associated with weight regains long term.
SCHEMA, ENVIRONMENT, PARTICIPANTS AND MEASURES:
The participants included a sample of middle-aged (mean = 59.3 years) and obese women (mean BMI = 36.8) who received a diet to lose weight in 6 months followed by a 1-year program of long-term care. Participants were encouraged to reduce caloric intake to achieve weight loss of 0.45 kg / week. Groups were classified 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 the rate of weight loss during the first month of treatment.
RESULTS:
The groups FAST, MODERATE, SLOW differed significantly in their weight loss for 6 months (- 13.5, -8.9 and -5.1 kg, respectively, ps <.001), and the FAST and SLOW groups differed significantly for 18 months (-10.9, -7.1 and -3.7 kg, respectively, ps <0.001). No significant difference was found for weight rebound within 6 and 18 months (2.6, 1.8 and 1.3 kg, respectively, ps <0.9). Groups FAST and MODERATE were 5.1 and 2.7 times more likely to get weight loss of 10% at 18 months the group SLOW.
CONCLUSIONS:
Collectively, the results show benefits in the short and long-term weight loss rapid initial. A rapid weight loss causes greater weight reduction and long-term maintenance, and are no more susceptible to weight regain that person was a gradual weight loss.
